Ukuzalwa kobomi obutsha kuyinkqubo yokuthuthumela kunye noxanduva, luqala ngochumiso lweqanda elinesilonda sesinambuzane. I-zygote esiphumelayo ihamba kwiinqanaba zokuphuhliswa ukuya ekuvelweni komntwana kunye nokuzalwa komntu omtsha.
Ukufakela umquba kunye nokukhulelwa - le ngongoma ebalulekileyo ekufuneka uyenze ngayo yonke imbopheleleko, kuba oku kuxhomekeke kwimpilo yengane ezayo. I-Conception ihlanganisa iiveki ezimbini zokuqala zokukhulelwa kwisondo ngaphambi kokulibaziseka kwimihla kunye nezinye iimpawu zokukhulelwa.
Amanqanaba omhlaza
Inkqubo yokuchumisa ibandakanya izigaba ezintathu:
- Ukusebenzisana okude kunye nokuguqulwa kweqanda kunye nesidoda.
- Qhagamshelana ne-gamete ukusebenzisana kunye nokusebenza kweqanda.
- Ukungena kwendoda yesigxobo se-ovum kunye ne-syngamy.
Kwenzeka ntoni emva kokuchumisa kweqanda?
Kwizinto ezininzi ze-spermatozoa, enye kuphela ifinyelela kwi-ovum, ingena kwiigobolondo zayo ize ilukhumbuze kwi-ampullar isebe le-uterine tube. Ngokungena kwe-spermatozoa emibini, i-embroyo ehamba nge-triploid isakhiwe, etshabalalisiweyo. Ukungena kwiqanda kunokuphela kwesidoda esisodwa, intloko ihlala ngaphakathi, kwaye umsila kunye nendawo ephakathi ziyabhujiswa. Emva kokuhlanganiswa kwama-chromosomes kuba ngu-46. I-zygote yenziwa - isiteji esisodwa se-embryo (isigaba se-zygote sigcina iiyure ezingama-26 ukuya ku-30). I-zygote iyahlula, iintsuku ezintathu zihamba nge-tube ye-fallopian kwaye zingene kwisigxina se-uterine, apho siqhotyoshelweyo kwisiseko sokusebenza (le nqubo ibizwa ngokuthi i-implantation, iyenzeka ngosuku lwesithandathu-7 ngosuku lokukhulelwa). I-placenta ekugqibeleni yenziwe ngeeveki ezi-15 ukuya ku-16 zokukhulelwa, yenza imisebenzi yemiphunga, izintso kunye nesibindi kumntwana wesisu - ukusuka kwi-placenta ukuya kumntwana ngumkhumbi owenza umgca.
Kuthatha ixesha elingakanani ukufaka umquba?
Kuthatha ixesha elingakanani ukufaka umquba? Ukufakelwa kwemfuyo kwenzeka emva kokuvuthwa, ngaphakathi kweeyure eziyi-12. Ubude benkqubo, xa utyalwa emva kokukhulelwa, kuxhomekeke kubomi beqanda, obunempilo emfutshane ngaphezu kwe-spermatozoon (iiyure eziyi-12), ezinokugcina ubomi emzimbeni womfazi ukuya kwiintsuku ezingama-5. Ijubane lesidoda li-3-4 millimitha ngomzuzu, ngoko kufinyelela kwiqanda, kunokuba yure emva kokunyuka. Ngenxa yokuba ixesha lokuqalisa i-ovulation alichazi ngokuchanekileyo, ukukhulelwa kungenzeka iintsuku ezi-1-7 emva kokulala ngesondo.
Ukukhulelwa kunye nokuchumisa kwenzeka njani?
Umhla wokukhulelwa kunye nomhla wokuchumisa awuhambisani nakwiimeko ezininzi. Ukuba kuphela ukulala ngesondo kwenzeka ngexesha le-ovulation, ke le mihla iya kuhambelana, kodwa inokuthi ixhomekeke kuphela kwimeko yobomi obungasifanelanga besondo.
Intrauterine insemination
Kukho ne-intrauterine insemination. Inemvelaphi yokuvelisa kwaye iqhutyelwa kwimeko yokunciphisa ngokulinganisela kwisakhono sokuchumisa sesidoda somntu, ukuba le ntokazi iphilile. Kwakhona, ukusabalalisa i-intrauterine kwenzelwa xa kusungulwa umphumo ongalunganga we-mucus wesibeleko kwi-spermatozoa, eyaziswa
Inzame ye-WMO iphinda iphindwe ngexesha lojikelezo kathathu, i-sperm iyafumana unyango olukhethekileyo. Emva kokunyusa ukuveliswa kwesidoda, ijojowe ngqo kwindawo yombeleko, eyanciphisa kakhulu umgama kwiqanda. Uvavanyo lokukhulelwa kufuneka lwenziwe iiveki ezimbini emva kwenkqubo. Ukuba uchitha ixesha kunye nazo zonke iimpawu zokungena kwe-intrauterine, ukukhulelwa kubakho kuma-80% amatyala.
