Yintoni engahambelaniyo ngokwemizimba?
I-gynecology yanamhlanje ichaza imvelaphi yokulahleka kwezinto ezihamba ngamathambo njengento engafaniyo yohlobo lwezesondo. Kule meko, iingcali zincoma ukuhlolwa ngokucacileyo kwesi sibini ukufumanisa nayiphi na ingozi enkulu. Nangona kunjalo, ngenxa yeemeko ezininzi kunye nezizathu zendawo, akusiyo yonke isibini esivumelana naloo uphando. Yiya kweli nqanaba labantu abanesiphelo, abazama ukukhulelwa umntwana abazange baphumelele ngenxa yokulahleka kwemithwalo engapheliyo.
Enyanisweni, iseli nganye yesintu inegobolondo yamaprotheni, ngamanye amazwi, i-anti-leukocyte antigen eyenza imisebenzi ethile. Injongo ephambili ye-antigen ukufunyanwa kwamalungu angaphandle angena emzimbeni ngokuthe ngqo okanye ngokungathanga ngqo, kunye nokunika impembelelo kwisistim somzimba sokukhusela umzimba esithintela "ukusuleleka" kweentlobo ezahlukeneyo zamalungu enobungozi. Ngenxa yolu hlobo lokukhusela, ukukhuselwa komzimba kuqala ukuhlakulela ngokukhawuleza amaqumrhu okukhusela.
Ukuphumelela ukukhulelwa umntwana, amaqabane kufuneka abe neethahlu ezahlukeneyo zama-chromosomes, ezo, ngenxa ye-atypicality yazo, zandisa amathuba okukhulelwa komzimba kunye nokunyamezela (iintsholongwane zikhusela "ihlumela lothando" ukusuka kusengozini yokukhulelwa kwesisu). Ngaphandle koko, xa isethi ye-chromosome yabalingani ifana nayo, i-anti-leukocyte antigen ibona ukukhulelwa njengento yangaphandle kwaye ibangela inkqubo yokwenyuswa kwiplacenta yesibindi esingaxhaswanga. Ngenxa yoko ukungafani kofuzo lomntu kunye nowesifazane.
Ngaba kunokwenzeka ukuzala ngokungafaniyo kwemfuyo?
Lo mbuzo uceliwe, mhlawumbi, ngabo bonke abatshatileyo abanenjongo yokufumana umntwana wabo. Kodwa ngaphambi kokuthetha ngxaki, kuyimfuneko ukuba ihlolwe. Ukuze ufumane idatha kwi-survey ngokuphathelele ukuhambelana kwezofuzo, kufuneka ubeke isitoreji eninzi kwiiveki ezimbini. Inkqubo yolu vavanyo iquka amanyathelo amanyathelo ngamanyathelo amaqabane omabini: ukususwa nokuqhathaniswa kwamajeni e-DNA, kwakunye nokuhlolwa kwegazi ukusuka kwisini. Iziphumo zohlalutyo akufanele zidlule iisalathisi ngenye indlela, kuba iimbini ezimbini ezifanayo zama-chromosomes sele zithetha ngokungahambelani kwamagciwane esilisa kunye namabhinqa.
Ababelethi be-Gynecologists bathi ukukwazi ukunyamezela ngokupheleleyo umntwana kubalulekile ukuba ugcine amanyathelo amiselwe ngumgqirha, kuba amaqabane amaninzi amaninzi ayengqinelani, kwaye izazi ziyakwazi ukulawula kuzo zonke izigaba zokucwangcisa nokukhulelwa komntwana.
Ukungenelela kweziyobisi, i-vitro fertilization (IVF) okanye ukuchithwa kwe-ICSI yi-series yezenzo ezisemgangathweni esele zinika abazali bexesha elizayo ithuba lokuba nootata kunye noomama. Ukubonisana ngokufanelekileyo kwezityalo zemvelo kukuvumela ukuba ukhethe indlela nganye yesigulane ngasinye kunye kunye nezibini ezitshatileyo ngokubanzi.
