Kwindlela yokusetyenziswa ngobuncwane kwi-in vitro, iingcamango ze- IVF protocol zifutshane. Kuthetha inhlanganisela ethile yemithi yokukhuthaza umsebenzi we-ovari. Ukutyunjwa kwesigulane somgaqo-nkqubo kunomntu ngamnye (kuxhomekeke kwiminyaka yobudala, izifo ezithintekayo, imvelaphi ye-hormonal kunye nempumelelo yemizamo yangaphambilini yokusatshalaliswa kwangoku). Injongo yecandelo lethu kukuqwalasela iimpawu ze-protocol emide ye-IVF, kwaye zingaphi iintsuku ezihlala kuyo, kunye nezicwangciso zayo.
I-protocol ye-IVF ende ihamba njani?
- Isigaba sokuqala somgaqo-nkqubo omde xa uzama ukuchithwa kwezinto ezikhuselekileyo kukuthintela i-ovulation ngaphambi kwexesha. Ukwenza oku, iintsuku ezi-7-10 ngaphambi kokuqala kokuya esikhathini, isigulane sichazwe izidakamizwa ezithintela imisebenzi yama-ovari (oko kukuthi, ukunciphisa imveliso ye-hormone yokuvuselela i-luteinizing and follicle). Lezi yobisi umfazi kufuneka athathe iintsuku ezili-10 ukuya kwe-15, emva koko i-ultrasound ye-uterus kunye nama-ovari, kunye nokuhlolwa kwegazi kwizinga le-estradiol. Ukuba isiphumo asihambisani nokunyango lwayo, ngoko kufuneka izidakamizwa zithathwe iintsuku ezingama-7.
- Emva kokupheliswa kwezidakamizwa zokudambisa i-hormone kuya kwinqanaba lesibini leprotocol - ukuvuselelwa kwama-ovari. Ngenxa yoko, isigulane simiselwe i-hormone - gonadotropin, ekhuthaza i-ovulation. Ngenxa yoko, iifolli ezimbini okanye ngaphezulu ezipheleleyo zingakhula kwi-ovary. Ulawulo lwe-ultrasound lwenziwa ngosuku lwesixhenxe emva kokuqala kokungena kwe-gonadotropin. Kwiimeko ezininzi, le hormone kufuneka ithathwe kwiintsuku eziyi-8 ukuya kwe-12.
- Isigaba sesithathu senkqubo emide yinto ebizwa ngokuba yi-follicle. Kule nqanaba, ukukhula kobugqwetha kuqinisekiswa, apho i-ovules ekhulile iqulethwe khona. Kule meko, misela i-hormone ye-hormone yezidakamizwa - i- chorionic gonadotropin . Umlinganiselo oyintloko wokuthatha i-HCG kukuba ubuncinane ubuncinane bobuqili obuvuthiweyo kunye nenqanaba le-estradiol ubuncinane be-200 pg / ml nge-follicle. Ukulawulwa kwe-hCG kwenziwa iiyure ezingama-36 phambi kokuqokelela i-oocyte.
Ngaloo ndlela, saqhelana nobude be-protocol ende ye-IVF kwiintsuku. Into ephambili ngexesha lokuvuselela kukulandela ngokulandelelana yonke imiyalelo (thabatha izidakamizwa eziyimfuneko kwiintsuku) kunye nezifundo eziyimfuneko. Ukuphululwa komnye wabo kunokugqithisa umphumo osalindelekileyo.
