Sinobuchule bethu bokuzala umntwana onobulumko nangobulumko. Nguye osinike lona, isetyhini, ngokubonelela ngamandla amaqanda, ukwenzela ukuvelisa kuphela umntu oqolileyo, olungele ukudibana nomdaka - ngexesha lokuchumisa.
Khawucinge ngoko kwenzekayo emzimbeni wowesifazane ovuthayo. Ukuqala, ukuvuthwa yi-peak of maturation, ukwakheka kweqanda ngokwayo kunye nokuphuma kwayo kwisigxina esiswini. Ngenye inxalenye yomjikelezo wokuya esikhathini - umjikelezo ovulation wee-follicle eziliqela ezili-ovarian ngaphantsi kweempembelelo ze-hormone ze-estrogen, ezikhuthaza ukukhululwa kwe-hormone ye-luteinizing, qalisa inkqubo ekhokelela ekugqithiseni. Ngaloo ndlela, kuphela omnye wabo, esondela kwiindonga ze-ovary eziqhekezayo ngeli xesha, uphupha kunye neqanda elivuthiweyo liyiyeka.
Uyakuqonda njani ukuba kwakukho i-ovulation?
Abanye besetyhini abanentsholongwane ngomhla wokuvuthwa kunye nomhla emva kokuba banokuziva bengakhululeki ngendlela yentlungu kwisisu esezantsi. Oku kubangelwa kukuba ngexesha lokuphuka kwintollicle eludongeni lwe-ovary, umthamo wamanzi okanye igazi eyenziwa ngexesha eligqityiweyo livutha i-ovary. Iimpawu ze-ovulation zenzeka kwakhona:
- ukwanda kwamanzi e-mucosal;
- ukwanda kwinqanaba le-hormone progesterone kwi-plasma yegazi;
- kuncipha kwiqondo lokushisa elisezantsi ngosuku lovulo kunye nokwanda kwawo ngosuku olulandelayo.
I-Ovulation ingasetyenziswa kwakhona nge-ultrasound, ngoncedo lweemvavanyo zokuhlola, iifowuni zokuvavanya umgangatho wamahomoni emcinini, nokuhlalutya imeko ye-mucus phantsi kwe-microscope.
Ngoko, kwenzeka ntoni emva kokuvuthwa? Ubunzima beqanda ekhishwe kwisigxina sesisu kuya kuma-24 iiyure. Ukuba ngelo xesha okanye iintsuku ezimbalwa ngaphambili (ngenxa yokuba i-spermatozoa ayifuni kumzimba wesetyhini ukuya kwiintsuku ezi-7) ukulala ngokwesondo ngokugcwele, kunye neqanda liza kutyalwa enye ye-spermatozoons eneyona ndlela iphezulu yokukhulelwa (27-31%) .
Ngokuqinisekileyo, elowo umfazi oceba umntwana, kuyamdla ukuba uya kubonisa ukukhulelwa kokukhulelwa emva kokuvutha. Ukuze ungakhathazeki kusengaphambili malunga nombono ongaphumelekanga, kungcono ukuyeka ukuvavanya kuze kube lula ukulibaziseka kwinyanga. Okokuqala, ukunqamana kweqanda lomntwana kwi-uterus kunokuthabatha iiveki ezimbini emva kokuqumba, kwaye okwesibini, iimvavanyo zisekelwe ekuxilongeni emcini we-hormone eyaneleyo emva kokuchumisa kweqanda-hCG, kwaye yanele ngokwaneleyo emva kweentsuku ezi-5 okanye ngaphezulu ngethuba le-ovulation. Kuya kulungelelanisa ukuxilonga ukukhulelwa ubuncinane kwiiveki ezintathu emva kokuvuthwa.
Kodwa ukuba ukuchumisa akunakwenzeka, izinga leprogesterone egazini liyancipha, iqanda lifa kwaye lihamba kunye nokuya esikhathini.
