I-IVF ifaka ntoni?
Okokuqala, kufuneka kuqatshelwe ukuba kuzo zonke iinkalo, le nkqubo inokuthi ibe nemibono enxulumene nomzimba wowesifazane, ubukho okanye ukungabikho kokuphulwa kwakhe.
Nangona kunjalo, kwiimeko ezininzi, inkqubo ye-IVF iquka amanyathelo alandelayo:
- ukutyunjwa kwe-superovulation (igama lesibili - ukuvuselela ii-ovaries);
- ukugqitywa kwee-follicle kuma-ovari;
- ukuchumisa i-oocytes kunye nokulima kwazo;
- ukudluliselwa kwama-embrosi kwisibilini se-uterine;
- inkxaso yecandelo lolawulo;
- ukuxilongwa kokukhulelwa kwexesha elincinci.
Kwezinye iziganeko, ukugqithiswa kokufakelwa komzimba kungenzeka ngaphandle kwesigaba sokuqala, phantsi kweemeko zentshukumo yokuya esikhathini. Cinga indlela yokwenza i-IVF ngcaciso.
Ukuchithwa kwe-superovulation
Injongo yale nqanaba kukufumana iiseli ezininzi ezivuthiweyo njengoko kunokwenzeka kumjikelezo omnye. Kule meko, iindidi ezininzi zeziprotocols zingasetyenziswa. I-classic, okanye njengoko ibizwa kwakhona, ide, qalisa ngomhla we-21 womjikelo. Ihlala malunga neenyanga. Kule meko, ukhetho lwezicwangciso zokuvuselela, kwakunye neziyobisi eziza kulawulwa kwaye iifayili zazo zenziwa ngabanye. Ngokuphathelele umgaqo- mfutshane omfutshane , uqala ngeentsuku ezingama-3-5 zomjikelo kwaye uhlala kwiintsuku ezili-12-14 kuphela.
Kufuneka kuqatshelwe ukuba eli nqanaba libandakanya ukubeka iliso kwinkqubo yophuhliso lwee-follicle, kunye ne-endometrium, eyenziwa ngokusebenzisa umshini we-ultrasound. Kule meko, inani lezintluli, ubukhulu babo burekhodwe, ubukhulu be-endometrium buzinzile.
Ukugqithwa kwee-follicle
Le nkqubo ibandakanya ukususwa kweeseli zesini zesini ezisuka kumzimba. Kuqhutyelwa ngaphandle, usebenzisa i-ultrasound. Kule meko, ukusetyenziswa kweenaliti kusetyenziswa. Ngenxa yesiphumo, amaqanda ama-5-10 atholakala. Inqubo ngokwayo iyenziwa phantsi kwe-aneshesia ye-intravenous okanye yendawo. Kwiyure enye emva kocingo, lona wesifazane ushiya iziko.
I-oocyte ukuchumisa kunye nenkcubeko ye-vitro
Amaqanda, kunye kunye ne-spermatozoa ethathwe kumlingane okanye umnikeli, abekwe kwisidlo esisondlo. Kule nqanaba ukuchumisa kwenzeka. Ngoncedo lwezibilini ezide eziphantsi kwe-microscope, ukutyalwa kweqanda kwenzeka kwaye ukufakwa kwe-spermatozoon kuyo.
Emva koko kufike inkqubo yokulima, enokuthatha iintsuku ezingama-2-6, kuxhomekeke kwiprotocol ye-IVF ekhethwe ngugqirha.
Ukudluliselwa komzimba
Okokuqala, kufuneka kuphawulwe ukuba oku kuqhutyelwa kwimiqathango eyahlukeneyo yophuhliso lombungu: ukusuka kwi-zygote ukuya kwisigaba se-blastocyst. Ukuze ufezekise umphumo ophezulu, ngokwemiqathango yamazwe ngamazwe, ama-embryologists adlulisa ama-embrasi ama-2-3 kanye kanye.
Ukuba sithetha ngendlela ama-embro azaliswa ngayo nge-IVF, ngoko ke le nkqubo, njengomthetho, i-anesthesia ayifuni. Ngoncedo lwezicathulo ezikhethekileyo ezifakwe kwisigxina se-uterine ngokusebenzisa umsele womlomo wesibeleko, ama-embrasi akhulayo ahanjiswa.
Inkxaso yesigaba esilandelayo
Ukuxilonga ngokukhulelwa
Yenziwa ngokuseka i-hCG egazini legazi kwaye iyenziwa kakade ngomhla we-12-14 ukusuka kumzuzu wenkqubo. Ukuqinisekiswa kwe-ultrasound yempumelelo ye-IVF kungenziwa kwiintsuku ezingama-21 emva kokutshintshwa. Ngendlela, kuvela kulo mzuzwana (usuku lokutyala) loo parameter ithathwa njengexesha lokukhulelwa ne-IVF.
