Iqiniso Mayelana Nendlela Yokukhulelwa Ngomfana Noma Intombazane
Uma unenhliziyo yakho isethwe ekubeni nomfana noma intombazane, akungabazeki ukuthi uthola iseluleko nge-intanethi. Ungathenga ubulili "imikhumbi," ukwengeza kanye ne-vitamin Cocktails, imikhiqizo yolwazi, kanye nama-douche wesifazane othembisa ukuthi uzokwandisa izinkinga zakho zokukhulelwa umfana noma intombazane uma usebenzisa.
Eyaziwa nangokuthi ukukhethwa ngokobulili noma ukushayisana ngokobulili, kukhona ingxube yenkolelo, okungalungi, kanye (nesincane kakhulu) isayensi ngaphandle lapho.
Izeluleko eziningi azilimazi, kodwa ezinye zingalimaza. Okunye ukudla okukhethwa ngocansi kungaba yingozi kakhulu, futhi ezinye izindlela zokuzulazula ngokobulili zinganciphisa izingqinamba zakho zokukhulelwa nhlobo.
Kukhona ubuchwepheshe bokuzala obuzosiza ukuthi ube nentombazane noma umfana. Kodwa-ke, ziyabiza , ziza nezingozi zempilo , kanti namanje azikho amaphesenti angu-100 aqinisekisiwe. Ngaphezu kwalokho, akuwona wonke umtholampilo wokuzala ohlinzeka ngobuchwepheshe bokukhetha ucansi ngaphandle kwesidingo sezokwelapha.
Kulesi sihloko, uzofunda izizathu zokuthi kungani umzali angathemba ukukhetha ubulili bezingane zabo ezizayo, uthole ukubuka kabanzi kwezindlela "ezendalo" ezithandwayo ekubhekeleni ubulili, funda ngezindlela zokucwaninga kuphela zokucabangela intombazane noma umfana, kanye nezinkinga zokuziphatha ezibonakalayo zokukhethwa kocansi ngaphambili.
Kungenzeka ukuthi uMzali Wabazali Ungathemba Ukuba Nomfana Noma Intombazane
Kunezizathu zezokwelapha nezingezona zokwelashwa umzali angase afune ukuba nomntwana wezocansi ezithile.
Ohlangothini lwezokwelapha, zikhona izifo ezithintekayo zobulili ezixhunyiwe ngokocansi.
Isibonelo, i-hemophilia ne-Duchenne i-muscular dystrophy cishe ihlala njalo kubafana. Uma umndeni unomlando walezi zifo, bangase bafise ukukhulelwa intombazane.
Kodwa-ke, iningi labantu elibheke ngokuqondile umfana noma intombazane bafuna ukwenza kanjalo ngezizathu ezingezona zezokwelapha.
Isizathu esivame kakhulu ukulinganisela komndeni.
Yilapho umndeni usuvele unomntwana (noma izingane eziningi) zobulili obulodwa, futhi uthemba ukuthi ingane elandelayo izoba ngokobulili obuhlukile. Noma, uma umbhangqwana uthatha isinqumo sokuba nezingane ezimbili, futhi kakade unomfana (noma intombazane), bangase banqume kakhulu ukuthi ingane yabo yesibili ibe enye yezocansi.
Ucwaningo luye lwathola ukuthi emindenini enabo bonke abafana, imibhangqwana ingcono yokwandisa usayizi wabo womndeni owahlelwe ekuqaleni, inethemba lokuthi olandelayo "uzogcina" abe intombazane.
Ukulinganisela komndeni kuvame ukucatshangelwa komndeni ngokushesha, kodwa kungase kube yinkinga enkulu yomndeni. Isibonelo, uma ugogo nomkhulu unabazukulu kuphela, omunye wezingane zabo angase athembele ukunika ugogo nomkhulu umzukulu (noma ngokuphambene nalokho).
Ezinye izizathu umuntu angase akhethe ukuba nomfana noma intombazane zihlanganisa:
- Ukukhetha ukukhulisa ingane yezocansi ezithile : Uma umbhangqwana uhlela ukuba nomntwana oyedwa, bangathanda kakhulu ukuthi ingane ibe ngumfana (noma intombazane). Noma, umama ongashadile ohleliwe, isibonelo, angase azizwe ekhululekile ukukhulisa intombazane. Umbhangqwana ongashadile wesilisa noma wesilisa ongenaye owesifazane onomntwana onomuntu ongazizwa angase akhululeke ukukhulisa umfana.
- Izizathu zenkolo noma zenkolo : Amanye amasiko nezinkolelo zithanda ubulili obulodwa phezu komunye. (Ngakolunye uhlangothi, ezinye izinkolo ziyakuvimbela noma yiluphi uhlobo lokukhethwa kobulili ngaphambi kokuqala.)
- Ukufa kwengane : Uma umzali elahlekelwa yingane, bangathemba ukuthi babe nomunye umntwana wesini esifanayo. Ngaphandle kwalokho, bangase bafune ukuba nomntwana wobulili obuhlukile, ukuzama ukugwema izinkumbulo ezimbi ezihlobene nokulahlekelwa kwabo.
Yini Okunquma Ubulili Bengane Yakho
I-X ne-Y-chromosomes inqume ubulili. Iqanda lihlala liphethe i-chromosome ye-X, kuyilapho isidoda sinikeza i-X noma i-Y embryo.
Uma i-Y-sperm ifaka iqanda, uthola i-XY-umfana. Uma i-X-sperm ifaka iqanda, uthola i-XX-intombazane. (Kukhona izifo zofuzo lapho kukhona khona i-chromosome yocansi eyengeziwe, njenge-Klinefelter syndrome (XXY), kodwa lezo zifo azivamile futhi zingaphesheya kwalesi sihloko.)
Kucatshangwa ukuthi isigamu sezingane ezizalwa abafana kanye nengxenye kukhona amantombazane, kodwa lokho akulona iqiniso. Isilinganiso samanje sabantu besilisa nabesilisa singama-107 abafana namantombazane ayikhulu. Nakuba lokhu kusho ukuthi abafana abaningana bazalwa kunamantombazane, lokhu akusho ukuthi kunomqondo wokuthi umuntu unomntwana ophakeme kunokuba abe nentombazane.
Amandla okuzikhethela ngokocansi emndenini kunzima futhi angathinteka ubude phakathi kokukhulelwa, ukuzalwa kokuzalwa, ukutholakala kwezidakamizwa zemvelo, nezinye izinto (eziningi zazo ezingaziwa).
I-IVF ne-PGD: I-Scientific Method
Indlela kuphela yokuba nengane ekhethekile-cishe engamaphesenti angama-99 ngokunemba-i- IVF kanye nokuxilongwa kwe-genetic pre-plantation, noma i-PGD . Lokhu kwasiza ubuchwepheshe bokubeletha kwasungulwa ukuze kusize ukugwema isifo sofuzo esithile, kanti lokho kusesebenza kakhulu.
Kodwa-ke, i-IVF-PGD ingasetshenziswa futhi ukukhulelwa ingane yezocansi ezithile ngezizathu ezingezona ezokwelapha. I-IVF ne-PGD iyingozi kakhulu futhi iyabiza kakhulu , okwenza ukuthi iningi lemikhaya lingabikho. Ngisho nalabo abadinga i-IVF , ngenxa yokungabi nabantwana, ngokuvamile abakwazi ukukhokhela ukwelashwa.
Nge-IVF, izidakamizwa zokuzala zisetshenziselwa ukuvuselela ama-ovari womfazi. Umqondo wukuthi ama-ovari avuthwe amaqanda amaningi, esikhundleni sejwayelekile noma ezimbili ezenzeka emjikelezweni wemvelo.
Ngesikhathi sokuhamba komjikelezo, ngenkathi lona wesifazane engaphansi kwe-anesthesia, inaliti eqondiswa yi-ultrasound ifakwa ngodonga lwangasese ukuze lithole amaqanda. Umlingani wesilisa uhlinzeka ngesampula sowesilisa, ngaphandle kokuthi kusetshenziswe umnikezeli wesilisa. Khona-ke, ebhodini, amaqanda nesidoda bahlanganiswa. Ngithemba ukuthi amanye amaqanda azokhulelwa. Amaqanda aphethwe yimibungu.
Ukuze i-PGD iyingxenye yenqubo, amaseli ambalwa aphikisiwe emibungu ekhulayo. Lezi zithunyelwa ukuhlolwa kofuzo. Yileyo ndlela ukuthi inqume ukuthi yimiphi imibungu engama-XX (amantombazane) no-XY (abafana).
Owesifazane (noma umbhangqwana) angase anqume ukuthi yiziphi imibungu ezidluliselwa emuva embelethweni wesifazane. Isibonelo, uma efuna intombazane kuphela, khona-ke imibungu engu-XX kuphela izocatshangelwa.
Ngaphambi kokuba ucabange nge-IVF, kubaluleke kakhulu ukuthi uqonde zonke izingozi kumama nengane. I-PGD iza nezingozi zayo nezindleko zayo.
Ezinye izinto ezimbalwa okufanele uzikhumbule:
- Asikho isiqinisekiso sokuthi uzothola noma yimiphi imibungu yocansi oyithandayo. Ungathola yonke imibhalo engu-XX noma yonke i-XY. (Ukuhlunga i-Sperm kungathuthukisa izinkinga zakho; bheka okuningi kulokhu ngezansi.)
- Kuzodingeka ucabangele ukuthi uzokwenzani ngemibungu eyengeziwe yobuningi obungayifuni . (Ungase ubanikeze kumbhangqwana ongenalutho, uwalahle, noma awunikeze ucwaningo.) Ukwenza lesi sinqumo kungaba inselele ngokomzwelo nangokwemvelo.
- Ngisho ne-IVF ne-PGD ayikho amaphesenti angu-100 aqinisekisiwe. Amaphutha namaphutha kwenzeka.
- Njengalapho kungekho isiqinisekiso sokuthi uzothola umbungu wezocansi ozifunayo, i-IVF ayifuni ngisho nesiqiniseko sokukhulelwa. I-embrying edlulisiwe ayisho ukuthi uthatha ekhaya ingane .
- Akuwona wonke umtholampilo wokuzala ozimisele ukunikela nge-IVF ne-PGD ngenxa yezizathu ezingekho zokwelapha. Ezinye imitholampilo izozicabangela ukulinganisela komndeni.
Isibungu Ukuhlunga Nge-Insemination noma i-IVF
Kunenye inqubo yezokwelapha engaphumeleli njenge-IVF ne-PGD, kodwa inegunya lezesayensi kunanoma yiziphi izindlela "zemvelo". Lokho kuhlunga isisu, ikakhulukazi ngobuchwepheshe obubizwa ngokuthi i-cytometry yokugeleza. Ubuchwepheshe bunelungelo lobunikazi ngaphansi kwegama elithi MicroSort®.
I-MicroSort® yayingaphansi kwe-FDA ukucutshungulwa iminyaka eminingana, kodwa inkampani eqhuba ukuhlolwa kwe-clinic e-United States isuse isicelo sabo. I-MicroSort® ayisatholakali e-USA, futhi i-FDA ayizange ivume ngokomthetho noma ayivumeli ubuchwepheshe.
I-MicroSort® okwamanje iyatholakala eMexico, eNyakatho Cyprus, eMalaysia naseSwitzerland. Ngezinye izikhathi abantu baya kwelinye lalezi zindawo ukuze basebenzise ubuchwepheshe, ngokuvamile emitholampilo efinyelela embonini yezokwelapha kwezokwelapha.
I-sperm ikhetha nge-MicroSort® isebenza kanje. Le ndoda inikeza isampula yesidoda, eyenziwa ngokuzivuselela . Ngaphandle kwalokho, isampula yesimanga singase sivela kumnikezeli wesilisa. Insizwa idlula inqubo ekhethekile yokuhlanza ukukhipha uketshezi lwesisu nomuthi ongagudluki.
Khona-ke, amangqamuzana wesilisa abunwe ngombala okhethekile ophendula nge-DNA okuqukethwe okutholakala kumasamu omzimba. Amaseli wesilisa afakwa ku-cytometer yokugeleza, okuyinto yobuchwepheshe obwenza ukuthi ukuhlonza izinhlayiyana kulamanzi njengoba kudlula i-laser. Amaseli e-X aneziqu eziningi ze-DNA kunezingqamuzana ze-Y-sperm, ngakho-ke amaseli e-dyed X-dyed akhanya kakhulu uma edlula ukukhanya kwe-ultraviolet.
Yile ndlela ama-cell cell ahlelwa ngayo futhi ahlonishwe, ngamunye. Ubuchwepheshe abuphelele. Okwamanje akunakwenzeka ukuthola uhlobo oluhlanzekile lwe-x-sperm noma uhlobo lwe-sperm.
Isibonelo se-X noma se-Y singasetshenziselwa isibeletho sowesifazane nge-IUI , noma singasetshenziswa kanye ne-IVF yedwa noma IVF-PGD.
Lezi yizilinganiso zokuphumelela ezivivinyweni zemitholampilo ezenziwa eU.SA:
- Kulabo abafuna intombazane, amasampula wesiduna sowesifazane ayinamaphesenti angu-87 X-ethwele amangqamuzana omuthi. Uma isetshenziselwa ukuqeda i-insemination noma nge-IVF, lapho ukukhulelwa nokuzalwa kutholakala, amaphesenti angu-93 emibono yabangela intombazane.
- Amasampuli ahlukaniswe ngamaduna aqukethe amaphesenti angama-74 Y-ethwele amangqamuzana omzimba. Lapho ukukhulelwa okuphumelelayo nokuzalwa kutholakala, amaphesenti angama-85 aholela emntwaneni.
Amaphesenti angenhla abhekisela ekuphumeleleni kokuthola ucansi olufunwa ngumzali noma abazali abahlosiwe. Lezi akuzona amazinga okuphumelela emithi yokwelapha ngokujwayelekile.
Imijikelezo ye-IUI kulesi sifundo yabangela ukukhulelwa emitholampilo amaphesenti angu-14 esikhathi. Imijikelezo ye-IVF yayinezinga eliphezulu lokukhulelwa kwezingane ezingamaphesenti angama-30, futhi imijikelezo yokudlulisa embryo efriziwe yayinezinga elingama-32 emitholampilo yokukhulelwa. Lezi zazifaniswa nemiphumela yokuphumelela ekulindelwe ngaphandle kobuchwepheshe bokuhlunga isilisa.
Akukwazi ukuthi yiziphi izingozi ezingase zibe khona ekuvezeni ama-sperm cell kudayi, ukukhanya kwe-ultraviolet, noma ukucindezela okuphezulu okudalwe ku-cytometer yokugeleza. Kungase kube khona ingozi yokwanda kwe-chromosomal kumaseli wesilisa, kodwa okwamanje, asazi ngempela.
Njengoba kushiwo ngenhla, i-MicroSort® ayisatholakali e-USA. Uzodinga ukuhamba phesheya ukuyisebenzisa. Ukuvakasha kwezokwelapha zokwelashwa kokuzala kunemithelela, izindleko, nezinzuzo zayo okufanele zicatshangelwe.
I-Ericsson Albumin Method
Indlela yokuhlunga i-albin ye-sperm ukukhetha-okungcono eyaziwa ngokuthi i-Ericsson Albumin Method-iyindlela yokuphikisana yokukhetha ucansi ngaphambili. Kutholakale futhi kunelungelo lobunikazi nguDkt. Ronald Ericsson, okwamanje yiloluhlobo olulodwa kuphela lobuchwepheshe bokuhlunga isilisa e-USA.
Ukuphumelela kwalendlela kuphikisana kakhulu. Kukhona izifundo (eziningi zazo ezibandakanya uDkt. Ericsson ngokwakhe) eziye zabika ukuthi le ndlela ingaphakamisa izilinganiso ezithinta isondo esisodwa noma enye, kodwa kunezifundo ezingazange zithole impumelelo ngokusebenzisa indlela ye-albin filtration.
Ukuze uchaze ubuchwepheshe nje, indlela ye-Ericsson ihilela ukubeka amangqamuzana e-sperm ahlanjululwe phezulu kwesisombululo se-albin. I-albhamu iyinhlobo yeprotheyini ngokwemvelo etholakala emzimbeni. I-albinin igcwele ukwanda okwandayo, futhi kamuva kunzima kakhulu ngezansi.
Umqondo wukuthi amaseli ka-Y azogebha phansi afike afinyelele esitokisini esikhulu kunazo zonke. Okwenza lokhu kwenzeke-kungakhathaliseki ukuthi ijubane lamaseli we-Y-sperm noma ukukhanya kwabo okulula kakhulu uma kuqhathaniswa namaseli e-X-akucaci.
Kulabo abafuna umfana, indlela yokuhlunga ilandelwa yi-insemination , noma i-IUI.
Kulabo abafuna intombazane, i-IUI isetshenziselwa futhi ngemuva kokuthi ama-cell cells ahlungiwe, kepha imithi yokwelapha i-Clomid ingezwa kwiprothotho yokwelashwa. Kuthiwa ukuthi i- Clomid ishintshe umsila womlomo wesibeletho , okwenza kube ngcono kakhulu kuma-X-cell cell.
Yiziphi amathuba okuthola ucansi ofuna? Amazinga okuphumelela abikiwe ahlukahluka. Le nqubo kuthiwa iphumelele kangcono kulabo abanethemba lokuba nomfana, cishe cishe amaphesenti angama-80 abafana abahlelayo njengoba kuhlelwe. Kulabo abafuna intombazane, izinga lokuphumelela libikwa ukuthi lingamaphesenti angaba ngu-70. Phakathi kwamaphesenti angu-15 no-30 wezingane ezizalwa ngale ndlela ngeke kube ngobulili abazali abahlosiwe abayethemba.
Yiqiniso, lokhu kungokwezifundo ezithola ukuthi le nqubo iphumelele nakancane.
I-Shettles Method
Indlela ye-Shettles yokukhethwa ngocansi kuyindlela engcono kakhulu eyaziwayo yokucabanga ngomfana noma intombazane. Kuthiwa nguDkt. Landrum Shettles , owayeyiphayona elidala le-IVF, le ndlela isekelwe ekubonweni kwakhe kwesidoda eminyakeni yama-1950.
Ngenkathi uDkt. Shettles izinkomba zanyatheliswa ezincwadini zamaphephandaba ohlaziya ngaleso sikhathi, kamuva ubuchwepheshe nokucwaninga okulandelwayo kubonise indlela yokwenza iphutha.
Ukuze kucace, le ndlela ayinawo ukuqinisekisa kwesayensi yamanje. Akusebenzi.
Isibonelo, iningi le ndlela lithatha ukuthi i-Y isisu ibhukuda ngokushesha kune-X-sperm. UDkt Shettles weza kulesi siphetho ngokubheka ubungako nokuziphatha kwamasamu omzimba. Uqaphele ukuthi amangqamuzana amancane omzimba agijima ngokushesha kunamakhulu amakhulu, futhi wanquma ukuthi amangqamuzana amancane wesilisa kufanele abe yi-Y futhi athathe izinto ezinkulu ze-X-chromosome.
Abaningi ososayensi abalandelayo benza izinhloso ezifanayo, ngokusekelwe emsebenzini kaDkt. Shettles. Kodwa-ke, ukuhlaziywa kwesidakamizwa esisizwa ngekhompiyutha (CASA) -kungazange kwakhiwe kuze kube phakathi nawo-1980-sekutholile ukuthi lokhu akulona iqiniso. Amagciwane e-Y awathathi masinyane ngokulingana kunama-cell-X.
Nakhu okushiwo yi-Method Shettles, kanye nezinkinga.
Ithiphu ye-Shettles # 1: Uma ufuna ukuba nomfana, ukulala ocansini kuyisondelene ne- ovulation ngangokunokwenzeka. Okungcono, kungakapheli amahora angu-12 ngaphambi kokuvota kwakho okulindelekile. Futhi, gwema ucansi (noma sebenzisa amakhondomu) kuze kube manje. Imfundiso yukuthi amaseli we-Y afika eqanda ngokushesha, ngaphambi kokuba amasosha omzimba aphethe i-X angakwazi.
Uma ufuna ukuba nentombazane, yenza ucansi nsuku zonke uma isikhathi sakho siphelile, kuze kube yizinsuku ezimbili kuya kwezine ngaphambi kokulindela ukugoba. Bese, gwema ucansi. Futhi, gwema ukuya ocansini uma unomuthi ovuthwa kakhulu wesibeletho somlomo wesibeletho .
Inkolelo yokuthi i-X-ethwele isisindo samasamu abadobi abahamba kancane kodwa bayosinda isikhathi eside kunamaseli we-Y-sperm, futhi kuphela amasosha omzimba a-X azobe esekhona uma iqanda livulwa.
Inkinga ngalesi seluleko : Akunakwenzeka ukuba isikhathi socansi sibe amahora angu-12 ngaphambi kokuvuthwa. Ucwaningo luye lwabona ukuthi akukho ndlela yokulandelela ukuvota kwekhaya ekhaya leyo enembile.
Ukugwema ubulili ezinsukwini ezimbili ngaphambi kokuthi ulindele ukuvota kusho ukuthi ulahlekelwa izinsuku zakho ezivundile kakhulu. Kanti futhi, ukugwema ucansi uma unekhanda elimhlophe leqanda le-cervical mucus lisho ukuthi ugwema isikhathi sakho esivundile kakhulu.
Izingqinamba zakho zonke zokukhulelwa nhlobo-noma umfana noma intombazane-yehla.
Ngaphezu kwalokho, okubaluleke nakakhulu, izifundo zokulandelelwa ngesikhathi sokulala ngokocansi ziye zathola imiphumela exubile futhi engavumelani. Abanye bathola ukuthi ukulala ocansini eduze kwe-ovulation kwandisa amathuba okukhulelwa intombazane, ezinye izifundo zathola ukuthi zandisa amathuba okukhulelwa umfana, kanti abanye bakuthola ukuthi akuzange kwenzeke umehluko nhlobo.
Ithiphu ye-Shettles # 2: Uma ufuna umfana, yenza ucansi usebenzisa isikhundla sokungena kwangemuva , i-aka "isitayela se-doggy." Sebenzisa izikhundla zocansi ezithola umuthi oseduze nomlomo wesibeletho ngangokunokwenzeka ukuze unikeze "i-Y-sperm ngokushesha" amaseli anenzuzo.
Uma ufuna ukuthatha intombazane, yenza ucansi esiteshini sezithunywa zevangeli kanye nokungena "okungajulile", ngakho-ke imbongolo isuswa kancane emgodini wesibeletho, lapho imvelo yangasese igcwele khona kancane.
Inkinga ngalesi seluleko : Isikhundla socansi asithinteki ukuthi masinyane amangqamuzana omzimba athola kanjani iqanda. Manje sazi ukuthi ama-sperm amaseli ka-Y awagijimi ngokushesha kunama-cell ahamba no-X.
Ithimba le-Shettles # 3: Hlanganisa neviniga ukwandisa i-asidi yesifazane, ukunikeza amangqamuzana e-X-nzuzo. UDkt. Shettles ukholelwa ukuthi ama-X-sperm cells ayenamandla kunamaseli e-Y.
Inkinga ngalesi seluleko : U-Douching ungaphazamisa ukulinganisa kwe-pH yemvelo yesisindo sakho. Lokhu kungabangela ukucasuka nokutheleleka, futhi ususe umqubu womlomo wesibeletho okhulisayo osiza yonke insimu yesilisa ("abafana" kanye "namantombazane") asinde.
Ekugcineni, ukuwashisa kunganciphisa izinkinga zakho zokukhulelwa nhlobo. Okuningi ngalokhu ngezansi.
Ithiphu ye-Shettles # 4 : Uma ufuna ukuba nomfana, owesifazane kufanele abe ne-orgasm . Lokhu kuzokusiza amangqamuzana ase-Y ukuba agijime ngokushesha. Uma ufuna ukuba nentombazane, owesifazane akufanele abe ne-orgasm.
Futhi, ngokusho kukaDkt. Shettles, ukungenayo i- orgasm kuzokwenza ukuthi i-pH ibhalise imvelo yangasese ibe yinto engcono kakhulu ku-Y-ethwele isisindo samagciwane.
Inkinga ngalesi seluleko : Njengoba kushiwo ngenhla, manje siyazi ukuthi i-Y-chromosome ethwele amangqamuzana wesilisa ayigezi masinyane ngokulinganisa kune-X-carry cell sperm. Futhi, abukho ubufakazi bokuthi noma ukungenayo i-orgasm kuzothinta ubulili bomntwana okhulelwe. Ungaziphili i-orgasm egameni lesayensi-mbono!
I-Whelan Method
I-Whelan Method isekelwe eselulekweni sikaDkt. Elizabeth Whelan, owayeyisifo se-epidemiologist (i-epidemiologist isosayensi ohlola izifo). Indlela yakhe isekelwe ekucwaningweni kuka-1970 uDkt. Rodrigo Guerrero.
UDkt. Guerrero wathola ukuthi izinkinga zokukhulelwa umfana zaziphakeme kakhulu uma ukulala ocansini kwenzeka izinsuku eziningi ngaphambi kokuvuthwa kwegazi, futhi ukuthi izinkinga zokuba nentombazane ziphakeme kakhulu uma ubulili beba khona ngaphambi nje noma ngemva kokuvuthwa.
Lona iseluleko esiphikisana ngqo sikaDkt. Shettles. (Awakwazi kokubili kokubili.)
Njengalokhu iseluleko sikaDkt. Shettles, ukulandela amathiphu okukhetha ucansi ngobulili obulodwa kunganciphisa imithelela yakho yonke yokukhulelwa nhlobo. Uma ugwema ucansi ngezinsuku ezine ngaphambi kokuvuthwa, awunayo ucansi uma uvuna kakhulu.
UDkt. Whelan uthi kulabo abazama ukuba nomfana, amaphesenti angu-68 athola umfana wabo, futhi kulabo abafuna intombazane, baphumelela ngamaphesenti angu-58 esikhathi. Kubekho ukuqinisekiswa kwangaphandle kwalezi zibalo.
Indlela ye-O + 12
Indlela ye-O + 12-okusho ukuvuthwa kwamafutha kanye namahora angu-12-kuthiwa yenzelwe owesifazane owayefuna ukuba nentombazane kodwa waqhubeka enobafana ngendlela yeShettles.
Umqondo lapha ukuthi uma ufuna ukuba nentombazane, isikhathi sokulala ocansini amahora angu-12 edlule. Futhi, ubulili kuphela ngesikhathi esisodwa.
Ngaphandle kokungekho izifundo ngale ndlela, kunezinkinga ezimbili ezinkulu.
Enye, akunakwenzeka ukuba isikhathi sobulili senzeke amahora angu-12 ngemuva kokuvuthwa ngoba awukwazi ukuthola ihora eliqondile (noma ngisho nosuku) olulutholile. Indlela kuphela yokwenza kanjalo izoba nokuhlolwa kwe-ultrasound njalo. Ngisho noma kunjalo, umzuzu wokuvuthwa kungenzeka ungaphuthelwa.
Uma ucabanga ukuthi ishadi lakho lokushisa lomzimba eliyisisekelo liyakutshela usuku ovumile ngalo, ucwaningo lithole ukuthi lokhu akuyiqiniso. Ngenkathi i-BBT isichazamazwi ingakunikeza umbono wokuthi uma uvula, ukukhuphuka kwamazinga okushisa akutholaki ngokunembile usuku oluthile iqanda likhishwe ku-follicle. Ngokuqinisekile akukwazi ukukutshela ihora eliqondile.
Inkinga yesibili enkulu nge-O + 12 yukuthi ukunciphisa izinkinga zakho zokukhulelwa. Uma ufuna ukukhulelwa, ucansi kufanele lwenzeke ngaphambi kokuvuthwa , futhi kufanele ulale ocansini izikhathi ezingaphezu kwesisodwa ngesikhathi sakho esivundile.
Iqanda lihlala kuphela amahora angu-12 kuya kwangu-24 emva kokukhishwa kwalo. Ungase uphelelwe ngokuphelele ithuba lakho lokukhulelwa uma uzama ukwenza ucansi kanye kuphela, futhi emva nje kokuvulwa.
Isikhathi socansi
Lesi yisihloko esinzima kakhulu sokutadisha, ngoba awukwazi ukulawula ngokuphelele ukuhlolwa. Awukwazi ukuvala imibhangqwana phezulu ebhodini izinyanga ngenkathi bezama ukukhulelwa. Ngaphezu kwalokho, isikhathi esiningi, ubulili buba ngaphezu kosuku olulodwa kumjikelezo.
Kuye kwaba nemizamo eminingi yokuthola izinsuku "zemilingo" ukuba nomfana noma intombazane, konke kube nemiphumela ehlukahlukene:
- Omunye umcwaningi washo ukuthi uma ukukhulelwa kwenzeka ngosuku lokuvuthwa, cishe unomfana. Uma kwenzeka izinsuku ezimbili ngaphambili, kungenzeka ukuthi ube nentombazane.
- Omunye umcwaningi uphakamise ukuthi kungenzeka ukuthi ube nomfana uma ubulili kwenzeka izinsuku ngaphambi kokuvuthwa.
- Omunye usosayensi wachaza okuphambene nalokho, ukubiza ucansi okwenzeka eduze kwe-ovulation kwandisa izingqinamba zomfana, kuyilapho intombazane ingenzeka uma ubulili kwenzeka ezinsukwini ezimbalwa ngaphambili.
- Njengoba usuvele ufunde ngenhla-nje ucabangela uShettles, Whelan, no-O + 12-ungabona izindlela eziningi ezihlongozwayo ziphikisana!
Yingakho isifundo sowezibalo sika-2016 sazama ukuphendula lo mbuzo, ukuzama ukuthola ukucaca esihlokweni.
Ekubuyekezeni kwedatha, abacwaningi abakwazanga ukuthola ukuthi lobulili ngosuku oluthile lwalukwazi ukuholela kumfana noma intombazane. Kungaba kuhle (futhi kulula!) Uma ubulili besimiso singasakaza izinkinga-kodwa isayensi yamanje ithi akunakwenzeka.
Ukudla, Izithako, nokudla
Cishe zonke izidlo ezithinta ubulili ziwela ngaphansi kwezigaba ezintathu eziyisisekelo:
- Ikhalori namafutha adla
- Ukudla okubonakala kuthinta pH yomzimba wakho
- Ukwehlisa noma ukwandisa ama-amaminerali athile
Ngokusho kwama- calorie-fat theory , abomama abadla izidlo eziphakeme ngekhalori banamathuba okuba nomfana. Lapho izidlo zingaphansi kwama-khalori, intombazane inamathuba amaningi.
Lokhu kwakusekelwe kwizifundo zobungani bobulili obuguqukayo phakathi nempi nendlala. Nakuba ezinye izikhathi ezithile zesikhathi zibonisa ukushintsha kwesilinganiso socansi, ezinye izifundo azitholanga lokhu. Akungabazeki ukuthi okuqukethwe okunamafutha noma ikhalori kokudla kwakho kuzokushintsha izimo zakho zokuba nomfana noma intombazane.
Ngokomqondo we-pH wokudla , ungashintsha i-pH yomzimba wakho ukuba ube no-acidic noma ngaphezulu kwe-alkaline ngokusekelwe kulokho okudlayo. Kutholakale ukwedlulele ngokwengeziwe ukuba nentombazane; ama-alkaline amaningi kufanele akhulise amathuba okuba nomfana.
Lokhu kusekelwe ekuhloleni kwe-vitro ukuthi indlela amangqamuzana e-sperm asabela ngayo ekuvezweni kwemvelo. Kuyiqiniso ukuthi emvelweni webhu, i-X-sperm ingakwazi ukumelana nemibandela eningi elula kune-Y-sperm.
Nokho, kuphakama izinkinga ezimbili:
- Akunakwenzeka ukubikezela ukuthi amasilisa omzimba azosabela kanjani endaweni yemvelo ngokusekelwe kulokho okwenzeka esitokisini se-petri.
- Okwesibili, umzimba wakho usebenza kanzima ukugcina i-homeostasis, noma izimo ezifanele impilo yakho nempilo yakho. Lokhu kuhlanganisa ukugcina amazinga e-pH athile. Amazinga akho e-pH ushintsho ngokusekelwe kumahomoni akho (ahlukahluka kumjikelezo wakho wokuya esikhathini), isikhathi sosuku, amazinga okucindezeleka, nezinye izici eziningi kakhulu. Ngeke ukwazi ukulawula lokhu ngokwakho, ikakhulukazi ngezinga noma ngokunemba ongayidinga uma kungenzeka ukuba ucabange ucansi oluthile olusekelwe kumazinga e-pH.
Ngokusho kokudla okwenziwe ngamaminerali , ukudla okungaphansi kwe-sodium ne-potassium, kanye ne-calcium ephakeme ne-magnesium, kuthiwa kwandisa izinkinga zokuba nentombazane.
Kukhona isifundo esisodwa esincane ekusebenziseni lokhu kudla ngokuhambisana nobulili obuphelelwe yisikhathi. Baqeda ukuhlolwa kwegazi ukuqinisekisa ukuthi ukudla kudinga amazinga amaminerali aguqukile. Yonke imibhangqwana yayizama ukuba nentombazane.
Ngesikhathi sokudla, abesifazane kwakudingeka badle ukudla okulungiselelwe ngosawoti, badle imikhiqizo yobisi (okungenani amagremu angu-500 ngosuku), gwema amazambane (aphezulu e-potassium), bese uthatha i-calcium (500 kuya ku-700 mg) i-magnesium (400 kuya ku-600 mg), kanye ne-vitamin D. Izindleko zokwengeza zazihlukahlukene ngokusekelwe emisebenzini yomsebenzi wegazi.
Ngezikhathi zobulili, imibhangqwana yatshelwa ukuba igweme ukulala ngokocansi ezinsukwini ezimbili ngaphambi kosuku olulindelekile lokuvota kanye nezinsuku eziningana emva kokuvuthwa kwatholakala. Lokhu kulandela inkolelo yesikhathi socansi yeShettles ukuba ibe nentombazane.
Ucwaningo lwaba nenani eliphakeme kakhulu lokuphuma, okuqala ngamabhangqwana angu-150, futhi kuphelile nabesifazane abangu-32 kuphela abahlangana kokubili kokudla kanye nokulinganisa isikhathi sobulili. Kulabo, amaphesenti angu-81 abeletha amantombazane.
Ucwaningo lubuye lwathola ukuthi labo abangazange bazuze isikhathi esifanele, kodwa balondolozwe ekulandeleni ukudla, izinkinga zabo zentombazane zaziphakeme (kodwa hhayi njengezinga eliphezulu).
Isixwayiso mayelana nokudla okulinganayo ngokobulili : Ezinye zezidlo eziphakanyisiwe zikhona ngokweqile. Bangase balawule ngokucophelela ukudla okuhlukahlukene okudlayo noma ukudla kwakho kwekhalori. Ngesikhathi eside, ezinye zalezi zidlo zingalimaza impilo yakho. Kulabo abanomlando wokudla okuphazamisekile, ezinye zalezi zidlo zingabangela ukubuyela emuva.
Futhi, uma kuziwa ekuthatheni izithako, noma ukuvimbela ukufakelwa okuncane kwamaminerali (kufaka phakathi usawoti kanye ne-potassium), gcina engqondweni lokhu kungase kube yingozi empilweni yakho yonke.
Ngaphambi kokuqala noma yikuphi ukudla noma ukuthatha noma yiziphi izithako , khuluma nodokotela wakho kuqala.
Amabhokisi ngokubhekisana nezikhalazo
Ucwaningo lwe-Lab luye lwathola ukuthi ama-cell ahlobene no-X angakwazi ukumelana nokushisa okushisa okuncane okushisa kune-Y-carrying sperm. Ngokusekelwe kulokhu, kulabo abafuna ukuba nentombazane, amadoda akhuthazwa ukuba agqoke izikhalazo. Izikhalazo zibeke amathelethi eduze komzimba, ikhulise amazinga okushisa ama-scrotum.
Ingabe kukhona ubufakazi bokuthi lokhu kwenza umehluko? Cha.
Futhi, khumbula ukuthi uma uzama ngenhloso yokwandisa izinga lokushisa kwe-scrotum, uthatha ingozi yokunciphisa isibalo sabantu bonke-hhayi nje ama-cell a-Y abhekene namagciwane.
Ukuguqula Umzimba Wakho Omzimba PH NgeViniga noma I-Baking Soda
Inkolelo ye-douching yokukhetha ngokocansi ngaphambi kokuba ikhethwe isekelwe ebufakazini bokubheka ukuthi ama-X-ethwele amangqamuzana omzimba anenhlanhla kunama-cell asebenzisa i-Y. Ucwaningo (ku-petri izitsha) lithole ukuthi i-X-sperm ingakwazi ukubekezelela izindawo eziningi eziyinkimbinkimbi, futhi ukuthi i-Y-sperm yenza kangcono ezindaweni eziningi ze-alkaline.
Uma ufuna intombazane, izingosi zeluleki ezitshengisa ubulili zibiza ukuthi kufanele uphuze ngesisombululo seviniga, futhi uma ufuna umfana, ukusebenzisa isisombululo sokwebhaka sokwebhaka. Noma, futhi okuvame ukushiwo, zama ukumboza umunwe wakho nge-baking soda bese ubeka umunwe wakho esiswini sakho. (Eyaziwa nangokuthi "i-baking soda finger").
Ungenzi lokhu. Akukho bufakazi obuzokusiza ukuthi ube nomfana noma intombazane.
Futhi, kunezizathu eziningi zokungazami:
- Imvelo yakho yangasese-ngokwayo-idala izimo ezifanele ukugcina isidoda siphila uma ukhula kakhulu. Ukungaboni kahle kungadla ama-pH amahle futhi kuphelele ukubulala wonke amangqamuzana omuthi-hhayi nje ama-Y noma ama-cell we-sperm othembela ukukukhomba.
- Uzohlanza umcubu wakho wesibeletho , okudingeka ukhulelwe.
- Ungathola ukutheleleka noma ukuzwa ukucasuka kwesisu. Zombili lezi zinganciphisa izinkinga zakho zokukhulelwa. Abuye ajabule!
Izinkinobho zokukhetha ngokocansi e-Home
Kukhona imikhiqizo kanye "namakethi wokukhetha ucansi" ongayithenga. Ngokuvamile bafika ngolwazi noma izikhombisi-ndlela okufanele zilandelwe, kanye nezinhlobo ezihlukahlukene zamathuluzi noma izithako.
Kungase kuhlanganise idivaysi ye-douching (ngokuvamile nge-recipe yokulandela, ukwenza ekhaya), iziphakamiso zokudla kanye namamenyu, imikhiqizo yokulandelela i-ovulation njengamashmometers noma amaphuzu wokuhlolwa kwe-ovulation , njalonjalo. Ungase uthole ama-pH ahlose ukuhlola u-acidity noma u-alkalinity wesifazane wakho, izikhukhula zomlomo wesibeletho, noma isisu sakhe. Kungase futhi baphonsa ukuhlolwa kokukhulelwa noma amabili.
Abanye bahlanganisa amaqembu e-intanethi "ukwesekwa" noma amaforamu, ngokuvamile nje iqembu elizimele le-Facebook nabanye ababelethi abanethemba lokukhulelwa intombazane noma umfana.
Ungadli imali yakho.
Okokuqala, ngeke bakutshele noma yini ongazange uyifunde lapha, thola mahhala kwenye indawo ku-inthanethi, noma encwadini oyithatha emtatsheni wezincwadi.
Okwesibili kokubili, konke kusekelwe ebuchosheni obuningi "isayensi." Akukho bufakazi bokuthi ukuhlola i-pH ye-mucus yakho yesibeletho kuzokusiza ukuthi ube nomfana noma intombazane. Isikhathi esithatha isikhathi socansi-for-a-girl (noma umfana) into enhle kakhulu. Futhi akukho "magic" ukudla noma amamenyu azoqinisekisa ukuthi unomfana noma intombazane.
Okwesithathu, uma kuziwa ekufakeni izithako, ungcono ekuthengeni izithako ngokwakho .
Futhi khumbula ukuthi i-FDA ayilawuli izithako-ngakho-ke awukwazi ngisho nokuthi ukuxuba kwakho "umfana" kuqukethe lokho abakushoyo okuqukethe, becabanga ukuthi bayokutshela lokho okukuyo ngaphambi kokuthenga kwakho.
Ungabuye futhi uthenge ukuhlolwa kwe-ovulation eshibhile, ukuhlolwa kokukhulelwa, nokuhlolwa kwe-pH.
Okokugcina, amanye alawa masayithi angama siteshi ogaxekile . Ezinye ziyiqiniso, kodwa bambalwa amasayithi wokuphanga afuna ukutshontsha imininingwane yakho yekhadi lesikweletu.
Lezi zingosi zingaqiniseka. Bangase babe nobufakazi obukhazimulayo. Nokho, khumbula, wazi kanjani ukuthi labo bantu bangempela? Futhi kuthiwani ngabo bonke ababengajabuli? Ikakhulukazi uma ukubuyekezwa kushicilelwa yinkampani ngokwabo, awunayo indlela yokwazi ukuthi yiziphi izindaba ongafundile.
Bangase banikeze isiqinisekiso sokubuyisela imali, kodwa ingabe isiqiniseko sabo sihlanganisa ukubuyisela imali yakho uma ungatholi umfana noma intombazane oyilindele? Abakwazi ukukuthembisa lokhu, ngakho-ke qaphela.
Kodwa Umngani Wami U-XYZ futhi Wayenomfana / Intombazane
Kukhona izindaba eziningi zokuphumelela ezithunyelwe ngaphandle lapho. Ungabathola emaqenjini abanjwe ngokobulili kanye namaqembu e-Facebook , noma uwazwe kubangane abafunga ngendlela ethile abazama ngayo. Ungase futhi ufunde ubufakazi noma izibuyekezo kumawebhusayithi okukhethwa komzimba wezocansi.
Ngisho noma othile esebenzisa indlela enesiqiniseko sezesayensi, izinkinga zabo zokuthola ucansi abazifunayo zihle kakhulu-cishe 50-50! Lokho kuyoba njalo kuyiqiniso.
Ubufakazi be-anecdot hhayi ubufakazi.
Futhi khumbula ukuthi abantu bangase babuyele esithangamini, noma bathumele isibuyekezo ku-Amazon, uma bephumelela besebenzisa indlela. Labo abangatholi lokho ababekufunayo ngokuvamile baqhubekela phambili. Labo abathola ukuthi umfana (noma intombazane) abuyele eqenjini inkanyezi. Baphumelele! Bangase bathi bangcweti ukuthi ungayithola kanjani ingane oyifunayo.
Labo abangenayo impumelelo bancane amathuba okubuyela ukutshela indaba yabo. Bangase basolwa ngokungahambisani nezikhombisi-ndlela ngokwanele. Abatholi ilungelo lokuhlanganyela indaba ephumelelayo. Akukho nzuzo yokubika ukuthi bahlulekile emgomweni wabo.
Ukukhathazeka Ngokuziphatha Nokuphikisana Ngokukhethwa Ngocansi
Ngesikhathi abanye odokotela bephikisa ukuthi ilungelo lokukhetha ukuthi unomfana noma intombazane (ngaphakathi kwesizathu) luwela esigabeni esibanzi samalungelo okuzala, akuwona wonke umuntu ovumelanayo. Abazali abaningi ngasese noma bafisa obala intombazane noma umfana, kodwa kubonakala sengathi kukhona umugqa okhishwe uma kuziwa ekuthatheni izinyathelo zokwenza leso sifiso sifezeke.
Nazi ezinye zezimpikiswano ngokumelene nokukhethwa kocansi ngaphambi kokuqala:
- Ukuphikisana nomqondo wokuthandana komzali okungenasisekelo. Cishe cishe wonke umama nobaba abafuna ngempela umntwana wobulili obulodwa, kodwa babenomunye wabo, bazokutshela ukuthi bayamthanda lo mntwana kakhulu. Kodwa-ke, abanye banombuzo wokuthi ukukhetha okunjalo ngaphambi kokukhulelwa kungaphazamisa uthando olungenamthetho.
- Kungenzeka ukuthi uqale umthambeko ophuthumayo uqondise "abantwana abakha umklami." Abanye abahleli bezimiso zokuziphatha bakhathazeka ukuthi uma siqala ukuvumela abantu ukuba bakhethe ubulili bomntwana wabo, kuzoholela kubazali abazama ukukhetha ezinye izici ze-genetics yengane. Lolu buchwepheshe alukho manje, noma kunjalo.
- Ingozi yemiphumela yomphakathi, uma ubulili obulodwa buhlelwa ngaphezu komunye. Ezimweni lapho ubulili obulodwa buhlelwa ngaphezu komunye, ikhono lokukhetha ubulili bomntwana lungabangela ukungalingani kwesilinganiso sobulili emphakathini. Lokhu sekuvele kunenkinga e-China, lapho abafana bethandwa khona ngamantombazane. Isilinganiso sangempela sobulili lapho sasilinganiselwa ukuba sibe ngu-113.5 abafana kuwo wonke amantombazane ayikhulu. Izinkinga zokulingana ngokobulili emfundweni nakwezinye izindawo nazo zihlupheka kakhulu eChina.
- Ingozi yengane engahlangabezane nokulindela kobulili bomzali. Umzali ofisa ukuba nentombazane (noma umfana) angase abe nemibono ethile yokuthi kusho ukuthini ukuba intombazane (noma umfana). Kuthiwani uma ingane ingakutholi lokho okulindelwe? Lokhu kungaba nemiphumela yengqondo futhi kubangele izinkinga ebuhlotsheni bomzali nabantwana.
- Ukuphikisana kwenkolo ekukhethweni kocansi ngaphambi kokuqala. Ezinye izinkolo zingavumi ukuthatha izinyathelo zokuzama ukukhetha noma ukulawula ubulili bezingane zabo ezizayo. Ngisho nasezinkolweni lapho ubulili obulodwa (ngokuvamile owesilisa) buyawuthandwa ngaphezu komunye, ukuphazamisa "uhlelo lukaNkulunkulu" lungase lukhunjulwe.
Izwi elivela ku-Verywell
Abantu abaningi bafisa ngasese ingane yengane ethize. Mhlawumbe bahlale bephupha ngokukhulisa intombazanyana noma umfana omncane. Mhlawumbe bafuna ukukhulisa ingane yocansi ngalinye. Lezi zifiso ezivamile futhi akukho lutho lokuba namahloni ngakho.
Naphezu kwala mathemba, lapho umntwana ezalwa, cishe wonke umzali uzothi bayathandana. Ngesikhathi ingane ilapha, ubulili abukhathali.
Kukhona ubuchwepheshe obuncane bezokwelapha ezingakusiza ukuba nomntwana wezocansi ezithile, kodwa zingabiza kakhulu (njenge-IVF-PGD) noma azitholakali e-USA (njenge-Microsort®). Kukhona nezindlela ezihlukahlukene zokukhetha zobulili "zemvelo", iningi lawo elingenalo ukusebenza kwesayensi noma ukuma emhlabathini onamandla kakhulu. Yize izindlela eziningi zingenabungozi, akuzona zonke izingozi. Khuluma nodokotela wakho ukuze uthole isiqondiso.
