Amathuba okuba namawele awanqabile. Xa kuthelekiswa noluntu jikelele, omnye kuphela ekuzalweni kwama-30 ngamawele okanye ngaphantsi kwama-3 ekhulwini. Kodwa ezinye iintsapho zibonakala zibetha iingxaki ngokuphindaphinda ezininzi. Kungekudala, umfazi waseBrithani wenza iintloko xa ebeletha ikhefu lakhe lesibini-eneminyaka engama-21 ubudala. Umfana wakhe wokuqala nentombazana-wayeneminyaka emine ubudala xa kufika oodade babo.
I-Royal College yama-Midwives inqikelele ukuba iingxaki zalezi zihlunu ezilandelelanayo zamanqanaba ezincinci zineminyaka engaphezulu kwe-700,000 ukuya kweyoku-1, ekuqaphele ukuba kuqhelekileyo xa ukukhulelwa okuhlukeneyo kwahlukana ngama-singletons.
U mzekelo
Nangona iimeko zinqabile kakhulu, kukho iziganeko ezininzi zeentsapho ezineempendulo ezininzi. Nangona ezinye zihambelana nokuncedisa ukuzala, ezininzi zinjalo ngokukhawuleza. Ngokomzekelo, uKevin noLorraine Horan wase-Ireland, banamaqela amathathu amawele kwaye abazange basebenzise naluphi na unyango lokuzala. Kwaye eli nqaku libhekisela kwiintsapho ezimbini ezahlukileyo iiseshini zesibini zazimangalisa. Ngamanye amaxesha i-multiples ziphumo zonyango lokuzala; UFran Pitre uchaze ibali lalo maqoqo amathathu weewele kwiincwadi zakhe ze-Twins X3.
Iziganeko zokuba neyinye iqoqo lezinto ezininzi
Emva kokuba neeseti zamabini, ngaba kunokwenzeka ukuba ibhinqa liza kusekwa elinye? Kucingelwa ukuba ukunyuka komama osele sele ekhulelwe kwaye ethwele amawele; I-National Organisation of Mothers of Twins Iiklabhu zithi emva kokuba ubenamawele (i- dizygotic ) amawele, amathuba akho okubeka esinye isisombululo esinezihlandlo ezintathu ukuya kwezine kunabantu bonke.
Zombini kunye neendawo zokusingqongileyo zinganceda kule nto. Oomama abathwele amawele angama-dizygotic ngenxa ye-hyperovulation sele bekwazi ukuba namawele; kwaye emva kokuba ethwele ukukhulelwa kokubili, isibeleko saso sinokukwazi ukugcina ngokukhawuleza ukukhulelwa okulandelayo.
