Ukuzalwa okuphindwe kaningi kukhula, ikakhulukazi kwamawele, futhi ukuthakazelisa umphakathi ngokuphindaphindiwe kuyaqhubeka nokukhula. Lokhu kubangela imibuzo eminingi, kufaka phakathi lokho obiza amasheya ahlukene wezimpande. Funda isi-nomenclature namanye amaqiniso ngokuzalwa okuningi.
Ishadi elilula lezimiso zokuzalwa eziningi
Leli phepha elisheshayo lingakusiza ukwazi ukuthi ungabiza amasethi amaningi.
| Inani lezingane | Isikhathi esisebenzisiwe |
|---|---|
| 1 | Singleton |
| 2 | Amawele |
| 3 | Izintathu |
| 4 | Ama-quadruplets (ama-quads) |
| 5 | I-Quintuplets (ama-quints) |
| 6 | Ama-sextuplets |
| 7 | Ama-Septuplets |
| 8 | Octuplets |
| 9 | Amaphutha |
I-prefixes yezinombolo ezine kuya kweziyisishiyagalolunye zivela kuLatini kulazo izinombolo. Ukungashadile, iwele ne-triplet livela ku-Middle English.
Amawele ajwayelekile kakhulu kunezintathu noma ngaphezulu
Ngokusho kwe-United States National Vital Statistics Report, kunama-33.4 amawele amawele azalwe kuwo wonke ama-1000 azalwa ngokuzalwa kanye namasethi angu-101.4 wezintathu noma ngaphezulu kwabazali abangu-100 000.
Ngamanye amazwi, amawele ajwayelekile kakhulu (cishe amaphesenti angu-3 azo zonke ukuzalwa okuphilayo) ngokuhambisana nokukhulelwa nabantwana abathathu noma ngaphezulu (cishe amaphesenti angu-0.1 kubo bonke ababelethi abaphilayo). Lokhu kungamangaza abantu abathile, becabangela inani lokuzalwa okuphindwe kabili elibonwe kumaphephandaba noma emibonweni yangempela yethelevishini.
Izinguquko ku-Birthlet Multi-Order Multiple Births
Izinga lamawele amabili, i-triplet, kanye nokuzalwa okuphezulu okuqala ukuqala ukukhuphuka ngawo-1980, ikakhulukazi phakathi kwamhlophe abesilisa abamhlophe abangabaseSpanishi abaneminyaka engu-25 nangaphezulu ngenxa yokusetshenziswa kwezidakamizwa zokuzala nokusiza amasu okukhiqiza.
Ngesikhathi izinga lababeletha ababeletha likhuphuka ngamaphesenti angaba ngu-50, isilinganiso sezintathu ze-triplet ne-ephakeme ephakeme sanda ngamaphesenti angaba ngu-400.
Izinga lilinganiselwe ngokuphindwe kathathu nokuphindaphindwa okuphakeme kusukela ngo-1998 kuya ku-2004 futhi kusukela ngaleso sikhathi liye lahlehla, futhi liphinde liye eqenjini elifanayo labantu abanomthwalo wokukhula. Lokhu kubangelwa ukuguqulwa kokwelashwa okusizwayo, ikakhulukazi ekudlulisweni kwemibungu embalwa.
Amanani asalokhu aphindwe kathathu abakukho ekuqaleni kwawo-1980. Lokhu kukukhathazeka ngoba izingozi zokufa kanye nokugula okude isikhathi eside kuyaqhubeka kube ngaphezulu kakhulu kwezintathu kanye neziphindaphindiwe ze-oda eziphakeme kunama-singletons.
Ukuzalwa Kwezikhathi Eziningi Kwenzeka
Ungase uzibuze kahle ukuthi owesifazane ukhulelwa kanjani abantwana abaningi. I-biology ngemuva kwayo iyamangalisa kakhulu.
Ngokufanayo
Njalo ngenyanga, owesifazane ukhulula amaqanda avela esibelethweni sakhe (le nqubo ibizwa ngokuthi i-ovulation), engabe isetshenziselwa isidoda ukuze idale umbungu futhi, ekugcineni, i-fetus noma umntwana okhulayo.
Uma umbungu kwenzeka okwehlukaniswa emibungu emibili noma ngaphezulu, amawele afanayo (noma ngaphezulu) angabangela. Ngenxa yokuhlukaniswa kombungu, amawele afanayo afana ne-DNA efanayo. Yingakho banobulili obufanayo njalo.
Uhlobo
Ngakolunye uhlangothi, abanye besifazane bakhipha amaqanda angaphezu kweyodwa ngesikhathi sokuvuthwa; "bakhuluma nge-hyperovulate," okushoyo. Ochwepheshe abaqiniseki ngempela ukuthi kungani abanye besifazane be-hyperovulate nabanye bengakwenzi, kodwa kukholakala ukuthi kuyisakhi sezakhi zofuzo-i-gene hyperovulation. Ngaphezu kwalokho, iminyaka idlala indima, njengoba abesifazane abadala kuneminyaka engama-35 banamathuba amaningi okukhulula amaqanda angaphezu kweyodwa phakathi nomjikelezo wokuya esikhathini.
Uma owesifazane ekhishwa amaqanda amabili (noma ngaphezulu) ngesikhathi sokuvuthwa, khona-ke yilowo nalowo angase ahlwanyelwe umuthi ohlukile, enze imibungu ehlukile.
Kulesi simo, amawele angaba ngabafowabo (angafani), futhi angaba ngamadoda ahlukile noma ubulili obufanayo.
Kuyathakazelisa ukuthi ngezinye izikhathi izinqubo ezimbili ngenhla zenzeka. Lokhu kungaba nzima ukumboza ikhanda lakho nxazonke ngakho nasi isibonelo: Owesifazane u-hyperovulates, ukhulula amaqanda amaningi phakathi nomjikelezo wakhe wokuya esikhathini. Lawa maqanda ahlonywa yi-sperm, bese kuthiwa eyodwa noma ngaphezulu yale mbungu ihlukaniswe. Kulesi sibonelo, owesifazane angaba nokubeletha okuningi (njengama-quadruplets) nezingane ezimbili kuba amawele omndeni futhi amabili afana.
Izinkinga Zokukhulelwa Eziningi
Ekukhulelwe okuningi umama usengozini enkulu yalezi zinkinga:
- Ukuhlukumeza okuvame kakhulu kokukhulelwa okuningi kungukuzalwa kwangaphambi kwesikhathi.
- I-preeclampsia ivame kakhulu ekukhulelweni okuningi kunomuntu okhulelwe owodwa.
- Ukukhulelwa okuningi kubeka owesifazane engozini enkulu yokuthuthukisa isifo sikashukela sokukhulelwa.
- Ukucindezeleka kwe-postpartum kanye nezinkinga zempilo yengqondo yengane zingase zenzeke kakhulu kwabesifazane abanokukhulelwa okuningi.
Izwi elivela ku-Verywell
Uma wena, umlingani wakho noma othandekayo ulindele izingane eziningi, kuhle ukuthola ulwazi. Qinisekisa ukuthi ukhuluma nodokotela wakho ngezinye zezihloko ezinzima kakhulu ezifana nezingozi zomama nezomntwana zokukhulelwa okuphindaphindiwe ngokukhulelwa kwezingculazi.
