Umjovo we-oxytocin ngesikhathi sokubeletha
"Kwezinye izimo - ukungeniswa noma lapho ukuvuleka komlomo wesibeletho kungaqhubeki - umthamo omncane we-oxytocin osesimweni sokwenziwa kunikezwa ngomthambo. Yiqiniso, ukusetshenziswa kwayo kuvunyelwe, umgomo uwukujova kancane ngangokunokwenzeka », Kuchaza uDkt Ariane Zaique-Thouveny, udokotela wezifo zabesifazane e-Polyclinique Majorelle, isikhungo se-ELSAN e-Nancy.

Kodwa i-oxytocin nayo isetshenziswa ngesikhathi sokubeletha, ukuvimbela ingozi yokopha ngemva kokubeletha. “Umjovo womthamo olinganisiwe we-oxytocin ukhuthaza ukulethwa kwe-placenta,” kuphetha yena. Ngaphansi komphumela wokufinyela, ivumela isibeletho ukuthi sihoxe ngemva kokuxoshwa.
I-oxytocin inamuphi umphumela ekunceliseni ibele?
“Ubufakazi bokuthi i-oxytocin iyasebenza ekufinyezweni, iyaqhubeka ibabangela ngemva nje kokubeletha, ngesikhathi sokuphakelwa kokuqala”, kuqhuba uchwepheshe.
