Kungani amawele e-Dizygotic enza khona futhi yiyiphi evamile kakhulu?
I-Dizygotic kusho amaqanda amabili (ama-di) ahlolwe ( zygotes ). Amawele angama-dizygotic ayenzeka uma amaqanda amabili ekhulelwa ngamadoda amabili ahlukene. Amawele e-dizygotic ayaziwa nangokuthi amawele angamazwe noma angewona afanayo. Ziyindlela ejwayelekile kakhulu yamawele.
Ngokungafani namawele e-monozygotic (abuye aziwe ngokuthi amawele afanayo), amawele e-dizygotic awahlanganyeli izakhi zofuzo ezifanayo. Amawele e-Monozygotic ahlanganyela amaphesenti angu-100 omunye nomunye.
Amawele e-Dizygotic ahlanganyela amaphesenti angu-50 kuphela. Lokhu kufana nokufana kofuzo okutholakala phakathi kwabantwana bakithi ababelethwe futhi bazalwa ngezikhathi ezahlukene.
Kungani Umuntu Angabona Amawele E-Dizygotic?
Amawele e-dizygotic angase ayenzeke uma ama-oocyte amabili noma ngaphezulu (amaqanda) ekhishwa emjikelezweni owodwa. Uma ngamunye ekhulelwa, amawele angama-dizygotic angabangela.
Ngesikhathi ukwelashwa kwe-IVF , uma imibungu emibili noma ngaphezulu idluliselwa, ungase futhi ukhulelwe ngamawele (noma ngaphezulu.)
Imithi yezidakamizwa iyimbangela evamile yamaduna e-dizygotic. Kuncike ekusetshenzisweni kwezidakamizwa noma ukuzala, izinkinga zakho zokukhulelwa ngamawele ngenkathi uthatha izidakamizwa zokuzala ziphakathi kwamaphesenti angu-5 no-30.
Imithi efana ne- Clomid kanye nenqubo yokuzala injenge- IUI ne- IVF inesibopho sabaningi ababeletha e-United States.
Kodwa izidakamizwa zokuzala akuzona kuphela imbangela yamawele e-dizygotic. Izinkinga zakho zokukhulelwa amawele zingase zibe ngaphezulu uma:
- Unina uneminyaka engu-30 noma ngaphezulu
- Unina ubude kunesilinganiso
- Unomlando womndeni wamawele
- Ukhuluphele kakhulu
- UngumAfrika-waseMelika
Nansi ulwazi oluthe xaxa mayelana nezinkinga zakho zokubeletha amawele:
- Yini Okukhulisa Amathuba Wakho Amadodakazi
- Imibuzo: Ingabe Izinkinga Zakho Zokuthola Amawele Amakhulu Kunokuningi?
Yiphi Indawo Nezizwe Ezihlobene Nakho Nezimpikiswano Zakho Amawele?
Izinkinga zamawele zithinteke kakhulu ubuhlanga ngisho nendawo.
Labo bobuzwe base-Afrika banamathuba okuba namawele, kanti ama-Asiya angenakwenzeka. AmaYurophu awela phakathi.
Kodwa-ke, ngisho naphakathi kwezigaba ezibanzi, kungaba khona ukwahlukana okuningi.
Ngokwesibonelo...
- E-United States, amazinga wokuwahlukanisa ngo-2003 atholakala enama-15.8 ngehora elilodwa lokukhulelwa. Kubantu baseMelika baseCaucasus, izinga lalingu-15.7 ngehora elilodwa, kuyilapho kubamnyama baseMelika, bekuphakeme ku-17.2 kwayinkulungwane.
- EYurophu, izinga lokuguqa i-twinning ngonyaka ka-2003 laliyi-16.4 kwabazali abangu-1 000. E-Luxembourg nasePortugal, izinga lokugubula laliyi-11 ku-1 000. Qhathanisa lokho namazinga wokuwahlukanisa eDenmark, eGreece naseNetherlands lapho kwakunabantwana abangu-20 000 abazalwa-abaphindwe kabili.
- I-Nigeria inezinga eliphezulu lokubhabhisa ama-twinning, nge-twinning jikelele ye-dizygotic ye-40 ngokuzalwa kwaba-1 000. Noma kunjalo, ukuhlukahluka kutholakala ezindaweni ezihlukahlukene. E-Nigeria eNtshonalanga naseMpumalanga, amazinga wokuwahlukanisa aphakathi kuka-33 kuya ku-66.5 ngosuku lokuzalwa okungu-1 000. E-Nothern Nigeria, inani lalingu-19.4 per 1,000 kumaqembu athile.
Lezi zinguquko zitholakala ngamawele angama-dizygotic. Kodwa lokhu okungafani nendawo kanye nobuhlanga akutholakali amawele we-monozygotic, noma amawele afanayo. Izinga lamawele afanayo ahlala njalo kuwo wonke amazwe, okwenzeka cishe ku-4 ngokukhulelwa okungu-1 000.
Ama-Twist Dizygotic kanye nobulili
Ingabe uzoba namawele amantombazane, amawele amantombazane, noma amawele amantombazane?
Nazi izinkinga zakho:
- Amawele amantombazane amantombazane ayinhlobo ejwayelekile kunazo zonke amawele angama-dizygotic, avela amaphesenti angu-50 yesikhathi.
- Amawele amantombazane namantombazane ayingxenye yesibili evame kakhulu.
- Amawele amantombazane amantombazane ajwayelekile kakhulu.
Amawele E-Dizygotic Nezikhwama Zabo Amniotic ne-Placentas
Amawele e-dizygotic ngokuvamile anezikhwama ezihlukile zamamniotic nama-placentas. Lokhu kwaziwa ngokuthi i-dichorionic-diamniotic. (Ngezinye izikhathi kuthiwa u-Di-Di okwesikhashana.)
Lokhu kuyisethaphu esivamile kunazo zonke zamawele we-dizygotic. Ama-di-Di amawele anezingozi zokukhulelwa eziphansi kakhulu.
Kunezikhathi ezingavamile zamawele angama-dizygotic abelana nge-placenta eyodwa. Kulesi simo, ngamunye unesikhwama sakhe se-amniotic. Lokhu kubizwa ngokuthi i-monochorionic-diamniotic (i-Mo-Di okwesikhashana).
Izingozi ziphakeme kumawele afana ne-placenta, ngenxa yengozi ye- twin-to-twin syndrome syndrome . Ukukhulelwa kungabhekwa eduze.
Ngenxa yokuthi ama-placentas amabili angakwazi ukuxosha ngokuhamba kwesikhathi, kungaba nzima ukukhomba nge-ultrasound noma ngabe kukhona ama-placentas amabili noma owodwa kamuva ekukhulelwe.
Ngenxa yalesi sizathu, udokotela wakho angakuthumela i-ultrasound ngasekupheleni kwe-trimester yokuqala, lapho kusengenzeka ukubona ukuhlukaniswa kwama-placentas amabili.
Ukunciphisa Ingozi Yakho Yamawele Uma Usebenzisa Ukwelashwa Kwesizalo
Kuye kwaba nokwanda kwe-twinning ye-dizygotic emazweni athuthukile emhlabeni jikelele, futhi lokhu kwenzeka enkulu ngenxa yokusetshenziswa kokwelashwa kokuzala. Emashumini ambalwa eminyaka, ama-twin rates akhuphuka phezulu, kuze kube ngonyaka ka-2000, lapho amazinga ekugcineni eqala ukwehla kancane.
Bafinyelele phezulu futhi baqala ukwehla ngoba njengoba ubuchwepheshe bokunakekelwa kwezenzalo buye phambili, ochwepheshe bokuzala bafumene izindlela zokunciphisa inani lokukhulelwa okuphindwe kaningi. Umgomo wokunakekelwa kokungabi nabantwana kufanele ube yinye ingane enempilo, eyodwa ngesikhathi.
Akunakwenzeka ukuqeda ngokuphelele ingozi yamawele ngenkathi ukwelashwa kokuzala, kodwa izinketho ezimbalwa ziyatholakala.
Ukusebenzisa umthamo ophansi kunazo zonke zokwelashwa kokuzala : Ingozi enkulu yamawele ivela ngesikhathi sokusetshenziswa kwezidakamizwa zokuvuna (i-gonadotropins) kanye nokulala ngokocansi noma ukusabalalisa. Akukho ukulawula ukuthi zingaki izinhlobo ze-follicle ezingakhula noma zikhule.
Kodwa-ke, uma odokotela basebenzisa imishanguzo yokwanela ngokwanele ukugqugquzela i-follicle eyodwa noma emibili, izingqinamba ze-multiples zingancishiswa. Yiqiniso, uma kunezinhlobo ezimbili ze-follicles, ingozi yamawele iphakeme kunaleyo uma kune-follicle eyodwa kuphela.
Futhi, uma ngaphezulu kweyodwa-noma ezimbalwa kuya ku-follicle eziningana zikhula, udokotela angakwazi "ukukhansela" umjikelezo bese ucela lo mbhangqwana ukuba ungalalali.
Ukudluliswa kwe-embryo okungenayo i-IVF (SET-IVF) : Ngokufaka umanyolo we-in vitro, udokotela angakwazi ukulawula ukuthi imibungu eminingi idluliselwa esibelethweni. Lapho i-IVF yayisanda futhi ingasebenzi kahle, ukudlulisa imibungu emibili kuya emine ngesikhathi kwakungavamile. Ithemba ukuthi okungenani oyedwa "uzamathela." Kodwa ngezinye izikhathi, okungaphezu kokukodwa "kunamathele."
Manje, ngeziguli ezincane nezinhle zokugulisa, ukudluliswa kombungu ongashadile kuyindlela yokukhetha. Kulesi simo, i-embryo eyodwa yekhwalithi elihle idluliselwa. Kukhona ingozi ephansi kakhulu yokwabelana okufanayo. Kodwa ingozi ephakeme yokuwashaza i-dizygotic iqedwa.
Ukudluliswa kwe-embryo e-frozen IVF (FET-IVF) : Ukwenziwa ngcono kwe-cryopreservation kwenza ukudluliswa kombungu ongashadile kusebenze. Okufanelekile, umbhangqwana uzothola okungaphezu kweyodwa embryo yekhwalithi enhle. Kodwa kwenzekani emibungu engadluliswa?
Nge-FET-IVF, imibungu "eyengeziwe" ingahle iqhwa njengamanje. Khona-ke, uma ukukhulelwa kungenzeki, umjikelezo we-FET-IVF ozayo ungahlolwa.
Uma ukukhulelwa kwenzeka nge-embryo yokuqala idluliselwe, ungagcina imibungu egciniwe "eqhweni" yezingane zakubo, noma inganikelwa omunye umbhangqwana noma ucwaningo lwesayensi.
I-Trizygotic Triplets ne-Quadrazygotic Quadruplets
Uma amaqanda amathathu ehlwanyelwa izidakamizwa ezintathu ezihlukene, lokhu kungabangela izintathu ezintathu .
Uma amaqanda amane ahlwanyelwa izidalwa ezine ezihlukene, ungathola ama-quadruplets angu-quadrazygotic.
Kungenzeka futhi ukuthi umama okhulelwe nge-multiple order order ukuze abe namaqoqo amawele.
Isibonelo, ama-triplets angase aqale njengamawele angabonakali (noma amawele e-dizygotic). Khona-ke, enye yalezi zygote ihlukaniswa, iholela esethi yamawele afanayo (noma amawele e-monozygotic). Konke, uzoba namawele amabili afanayo kanye newele elilodwa elingafani nenza iqoqo lezintathu.
Uma uthola lokhu kunzima ukukuqonda, zama lokhu. Thatha amapeni amabili, elilodwa elibomvu nelinye elimnyama.
Dweba ubuso be-smiley nopeni obomvu, ngezinwele ezincane ezingaphezulu.
Dweba esinye ubuso smiley nephoyinti elimnyama.
Manje, kusukela ebusweni bomnyama obunzima, dweba imigqa emibili phansi naphuma, ngamunye eya ebusweni obusha obuhlukile be-smiley.
Kumbuthano oyedwa omkhulu, udwebe umugqa oseduze nenye yobuso obomvu kanye nobuso obombili obumnyama. Lezo ziyizintathu - amawele amabili afanayo (ipeni elimnyama) nelinye elilodwa "sibini" (ipeni elibomvu).
Noma kunjalo, iningi lamaphilisi e-high-order akhiwa ngamawele angafani.
