Ukuzalwa kokuphila okusha kuyinkqubo yokuthuthumela nokuzibophezela, iqala ngokukhulelwa kweqanda elinesilonda sesidoda. I-zygote eholayo ihamba ngezinyathelo zokuthuthukiswa ekudalweni kwe-fetus nokuzalwa komuntu omusha.
Ukukhulelwa nokukhulelwa - leli phuzu elibalulekile okudingeka ulilungiselele ngayo yonke imithwalo yemfanelo, ngoba lokhu kuncike empilweni yengane ezayo. Umklamo uhlanganisa amasonto amabili okuqala wokukhulelwa ekuziphatheni ngokobulili kuze kube sekupheleni kokuya esikhathini kanye nezinye izimpawu zokukhulelwa.
Izigaba zokukhulelwa
Inqubo yokukhulelwa iqukethe izigaba ezintathu:
- Ukuxhumana okude nokuguqulwa kwamaqanda nesidoda.
- Thinta ukuxhumana kwe-gamete nokusebenza kweqanda.
- Ukungena kwesibindi segobolondo le-ovum kanye ne-syngamy.
Kwenzekani emva kokukhulelwa kweqanda?
Eziningi ze-spermatozoa, eyodwa kuphela ifinyelela i-ovum, ingene kwigobolondo layo iphinde ifake emnyangweni we-ampullar we-tube uterine. Lapho ukungena kwe-spermatozoa, ukungena kwe-spermatozoa kabili, kwakhiwa umbungu, ozobhujiswa. Ukungena eqanda kungenza umuthi owodwa kuphela, ikhanda lihlala ngaphakathi, futhi umsila kanye nengxenye ephakathi zibhujiswa. Ngemuva kokuhlanganiswa kwama-chromosomes kuya kuba ngu-46. I-zygote yakha - isiteji se-unicellular ye-embryo (isigaba se-zygote sihlala amahora angu-26-30). I-zygote ihlukanisa, izinsuku ezintathu ihambahamba emgodini we-fallopian iphinde ingene emgodini we-uterine, lapho ifakwe khona ungqimba osebenzayo (le nqubo ibizwa ngokuthi i-implantation, kwenzeka ngosuku lwesithupha lwenyanga yesi-6). I-placenta ekugcineni yenziwa ngamasonto angu-15-16 okukhulelwa, yenza imisebenzi yamapayipi, izinso nesibindi kumntwana - kusukela e-placenta kuya emfuswaneni yizona izitsha ezifaka intambo yomlomo.
Kuthatha isikhathi esingakanani ukutshala?
Kuthatha isikhathi esingakanani ukutshala? Ukukhulelwa kwenzeka emva kokuvuthwa, ngaphakathi kwamahora angu-12. Ubude besikhathi, lapho ukukhulelwa kwenzeka emva kokukhulelwa, kuxhomeke ekuphileni kweqanda, eliphila isikhathi esifushane kune-spermatozoon (amahora angu-12), okungasindisa impilo emzimbeni wesifazane kuze kube yizinsuku ezingu-5. Ijubane le-sperm liyizigidi eziyi-3-4 ngomzuzu, ngakho-ke sifinyelele iqanda, kungaba ihora ngemva kokujula. Ngoba isikhathi sokuqala kwe-ovulation asibikezeli ngokunembile, ukukhulelwa kungase kwenzeke izinsuku ezingu-1-7 emva kokulala ngokocansi.
Ukukhulelwa nokukhulelwa kwenzeka kanjani?
Usuku lokubeletha nosuku lokukhulelwa aluhambisani nezeziningi. Kuphela uma ukulala ngokobulili kwenzeka ngesikhathi sokuvuthwa kwegazi, lezi zinsuku zizovumelana, kodwa zingagcinwa kuphela uma kwenzeka impilo engavamile yocansi.
Intrauterine insemination
Kukhona futhi insemination ye-intrauterine. Unomvelaphi wokufakelwa futhi wenziwa uma kwenzeka ukuncipha okulinganiselwe emzimbeni wokufaka umquba wesilisa, uma owesifazane ephilile. Futhi, i-intrauterine insemination yenziwa lapho kusungulwa umphumela omubi we-mucus womlomo wesibeletho ku-spermatozoa, eqaliswa
Umzamo we-WMO uphindwa ngesikhathi sokujikeleza izikhathi ezingu-2-3, isidoda sithola ukwelashwa okukhethekile. Ngemuva kokukhulisa ukuvuthwa kwesidoda, ijojowe ngqo endaweni yesibeletho, okuyinto eyanciphisa ibanga iqanda. Ukuhlolwa kokukhulelwa kufanele kwenziwe 2 amasonto emva kwenqubo. Uma uchitha isikhathi futhi nazo zonke izici ze-intrauterine insemination, ukukhulelwa kwenzeka kumacala angu-80%.
