Umsebenzi upapashwe kwi-Biorxiv Presptions. Ukufumana umntwana kwiXesha Eliphakathi, njengoko kuyaziwa, kuyingozi kakhulu kwaye kuquka umngcipheko obalulekileyo kumama, kunye nomntwana. Abafazi babulawa ngosulelo lwasemva kwexesha, ukukhunjulwa kwe-Utoris kunye nezinye iingxaki, ukuze ubomi bobomi besini esihle ngaloo maxesha simfutshane kakhulu kunabantu.
Akumangalisi ukuba abantu abaninzi baqhagamshelwe ngokuzala umntwana, ababecela ukunxiba iCawa yamaKatolika kubafazi. Phakathi kwabo kukho izingqinisiso ezininzi ezibizwa ngokuba ziibhotile zokuzalwa ezenziwe ngeendlela ezahlukeneyo-isilika, iphepha, i-chirchiment. Kwiindawo ezininzi ezifanayo, imithandazo ebhalwe ekukhuseleni umntu nempilo yakhe, kuquka ukukhuselwa kokuzalwa.
Uninzi lwe-bolts "yoomama" utshatyalaliswa emva koHlaziyo lweCawe, ke lininzi kuphela inani elincinci ukuza kuthi ga namhlanje. Imibhalo-ngqangi yamandulo ibonisa ukuba ezi khabhathi zazisetyenziswa ngexesha lokuzala njengohlobo "lonyango", kodwa akukho bungqina buthe ngqo bokunxiba iitawuli ngexesha lokuzala.
Izazinzulu ezivela kwiCambridge, e-Edinburgh kunye neYunivesithi yaseLondon (e-United Kingdom) zigqibe kwelokuba zibambe uhlalutyo lwe-biomoleccular yenye yeetawuli ezigciniweyo "zoomama" kwaye zifumane impendulo yalo mbuzo. Kuyaphawuleka ukuba abaphandi abakhethe ngqo isampulu, eyayigcina imithandazo ethile yokukhuselwa kwabasetyhini kunye nokukhankanywa kwabasetyhini kunye nokuzalwa komfazi. Ukongeza, bububungqina obubonakalayo bokuba ibhanti yayisetyenziswa kwaye yayinxiba, kuba eminye imibhalo kunye nemifanekiso icinyiwe, kukho amabala amaninzi emvelaphi.
Emva kokuhlalutya iisampulu ezithathwe kwezi ndawo, izazinzulu zafikelela kwisigqibo sokuba ziyahambelana neeproteni zabantu zeCervaco-Vaginol fluid. Ngokudibeneyo nezibakala zingentla, oku kungathathwa njengebubungqina bokuba ibhanti isetyenziswe kakuhle ngexesha lokuzalwa komntwana.
