Ucwaningo lubonisa ukuthi ama-Twins Amantombazane ahamba kahle kunama-Boy Twins
Izimpi phakathi kobulili ziye zahlaselwa ngokungapheli, kodwa isifundo sinikeza umkhawulo oqondile kubesifazane. Abacwaningi eHelen Schneider Hospital for Women kanye neSackler School of Medicine eYunivesithi yaseTel Aviv ku-Israyeli kusanda kuphetha ngokuthi imiphumela yokukhulelwa kwamabili iyakhuliswa uma okungenani elinye lamawele liyintombazane. Ucwaningo lwango-2009 luhlolisise ukukhulelwa kwezingu-2 500 futhi lwahlukana nemiphumela yentombazane, intombazane, intombazane, namawele amantombazane.
Uyini umehluko phakathi kwamawele amancane namantombazana ama-girl?
Abacwaningi bathola ukuthi ukutholakala kokubeletha kwangaphambi kokubeletha kwakungaphezulu kwamaphantshi amantombazane, futhi izingane zazinenani eliphansi lokuzalwa kwezibalo kanye namazinga okukhula okuphansi lapho bobabili amawele bengamaduna. Phakathi naleso sikhathi, amawele amantombazane ayenezinkinga ezimbalwa zokuphefumula nezenhliziyo. Ngokuthakazelisayo, imiphumela yabonisa ukuthi ithatha intombazane eyodwa kuphela ukuthuthukisa umphumela womfana; ngaphesheya kwebhodi, abafana abanamawele amabili abahle kakhulu kunamaqoqo amawele amawele.
- Ingozi yokulethwa kwesikhashana (ngaphambi kwamasonto angu-31) yayiphezulu kumawele amabili wesilisa.
- Amaphangi amantombazane anesisindo sokuzalwa esincane nesilinganiso sokukhula esincane.
- Amawele amantombazane ayenezinkinga ezimbalwa ngobuchopho bawo namaphaphu.
Abacwaningi bacaphuna "isici esesiphambeko esilisa," echaza ukuthi ukuthutha ukuphazamiseka kwezidakamizwa ezivela emfubusini wesilisa kunomthelela omubi kwamanye amawele. Baphinde bathi abesilisa bangase bancintisane nezinsiza zokudla okunomsoco ngokumelene nesisu somntwana, okukhula kancane kancane, okwandisa isisindo somzimba wesilisa.
Kufanele Ngikhathazeke Ngomfana Wami Amawele?
Okunye ukuhlolwa kwezinsana ezingakabonanga kuqaphela ukuthi abantwana besifazane banenzuzo. Ngokwesibonelo, ekucwaningweni kwezinsana ze-singleton, laba bafana babe namanani aphezulu kakhulu ezinkinga ezithile, nakuba ngokuvamile ziba ngaphezu kwamantombazane ekuzalweni. Izigameko eziphakeme zokukhubazeka nazo zazihlobene nabesilisa.
Kodwa-ke, ukulinganiselwa okuningi okuhlotshaniswa nalolu cwaningo lwezinwele kuye kwavunyelwa. Ngolunye uhlangothi, lufundela amawele ngama-placentas amabili ahlukene, ngaphandle kokufaka ingxenye yamawele e-monozygotic . Futhi, ayikwazi ukuhlukanisa phakathi kokuphindaphindiwe okukodwa noma ngosizo lokuzala, okungathinta umphumela wokukhulelwa. Amaphesenti angaphezu kwamatshumi amabili kwezintathu ezibekwe kulolu cwaningo kwakuyizibili zombili zesilisa nabesifazane, kanti cishe ama-15% ayenamawele amabili womzimba wobulili obufanayo. Okokugcina, isimo sokuphindaphinda saleso sifundo singenza sibe ngaphansi kokubheka. Odokotela abaningi bayavuma ukuthi imiphumela yalolu cwaningo akufanele ishintshe indlela ukukhulelwa okubili okuphathwa ngayo.
