I-ECO - iyini futhi yenziwa kanjani?

Isifinyezo se-IVF sizwakala yibo bonke abesifazane, kodwa akubona bonke abesifazane abakwazi lokhu nokuthi kwenziwa kanjani. Ngaphansi kwaleli gama, emithini yokuzala, kuyisiko ukuqonda ukukhulelwa kweqanda elivuthiwe elivuthiwe ne-spermatozoa ngaphansi kwezimo ze-laboratory. Ngamanye amazwi, ukwethulwa kweseli wesilisa ocansini kwenzeka ngaphandle komzimba wesifazane. Le nqubo ikhulisa kakhulu amathuba okukhulelwe futhi isetshenziswe ezimweni lapho imibhangqwana eshadile, ngenxa yezizathu ezithile noma enye, ingazikhulelwa ngokwemvelo isikhathi eside. Ake sibheke i-IVF ngokuningiliziwe, futhi sikutshele ukuthi le nqubo ihamba kanjani ngezigaba.

Iyini i-IVF?

Okokuqala, kufanele kuphawulwe ukuthi kuzo zonke izimo ezifanayo, le nqubo ingaba neminye imiyalezo ehlobene nokusebenza komzimba wesifazane, ukutholakala noma ukungabikho kokuphulwa kwakhe.

Nokho, ezimweni eziningi, inqubo ye-IVF ihlanganisa izinyathelo ezilandelayo:

• ukufakwa kwe-superovulation (igama lesibili - ukugqugquzela ama-ovari);
• ukukhishwa kwama-follicles ema-ovari;
• ukukhulelwa kwama-oocyte eqoqwe kanye nokulima kwawo;
• ukudluliselwa kwemibungu emgodini wesibeletho;
• ukusekelwa kwesigaba sokuqamba;
• ukuxilongwa kokukhulelwa kwenkathi encane.

Kwezinye izimo, ukuxoshwa okufakwayo kungenzeka ngaphandle kwesigaba sokuqala, ngaphansi kwezimo zemjikelezo wemvelo. Cabanga ngendlela yokwenza i-IVF ngokuningiliziwe.

Ukukhishwa kwe-superovulation

Umgomo walesi sigaba ukuthola amangqamuzana amaningi asusiwe ngangokunokwenzeka emjikelezweni owodwa. Kulesi simo, izinhlobo eziningana zezinhlelo ezibizwa ngokuthi izivumelwano zingasetshenziswa. I-classics, noma njengoba ibizwa nangokuthi, ide, qala ngosuku lwe-21 lomjikelezo. Kuphela cishe inyanga. Kulokhu, ukukhethwa kwehlelo lokuvuselela, kanye nezidakamizwa okufanele zenziwe futhi amadoksi abo ayenziwe ngabanye. Ngokuqondene nenqubo emfushane , iqala ngezinsuku ezingu-3-5 zomjikelezo futhi iphela izinsuku ezingu-12-14 kuphela.

Kumele kuqashelwe ukuthi lesi sigaba sithinta ukuqapha inqubo yentuthuko ye-follicles, kanye ne-endometrium, eyenziwa ngokusebenzisa umshini we-ultrasound. Kulesi simo, inani le-follicles, ubukhulu balo bulotshiwe, ubukhulu be-endometrium bubekiwe.

Isikhathi se-follicles

Le nqubo ihilela ukukhishwa kwamaseli wesini omzimba avela emzimbeni. Kuqhutshwa ngaphandle, usebenzisa i-ultrasound. Kulokhu, kusetshenziswe izinaliti. Ngenxa yokuxhaphazwa, amaqanda ama-5-10 atholakala. Inqubo ngokwayo iyenziwa ngaphansi kwe-anesthesia engaphakathi noma ephakathi. Ngemuva kwehora ngemuva kocingo, lona wesifazane ushiya isikhungo.

Ukukhulelwa kwama-oocyte kanye ne-in vitro isiko

Amaqanda, futhi kanye nabo spermatozoa othathwe kumlingani noma umnikeli, bafakwa emkhatsini wezakhi. Kule nkathi ukuthi ukukhulelwa kwenzeka. Ngosizo lwamatayipi amade aphansi ngaphansi kwe-microscope, ukukhulelwa kweqanda kwenzeka futhi ukwethulwa kwe-spermatozoon kuyo.

Emva kwalokhu kuvela inqubo yokulima, okungathatha izinsuku ezingu-2-6, kuye ngokuthi i-IVF protocol ekhethwe udokotela.

Ukudluliswa kwesisu

Okokuqala, kufanele kuqashelwe ukuthi lokhu kuqhutshwa kungahle kwenziwe ezinyathelweni ezihlukahlukene zokuthuthukiswa kombungu: kusukela ku-zygote kuya kwisiteji se-blastocyst. Ukuze kuzuzwe umphumela ophezulu, ngokwemigomo yamazwe ngamazwe, ama-embryologists adlulisa imibungu emibili ngesikhathi esisodwa.

Uma sikhuluma ngokuthi ama-embri agcwaliswa kanjani nge-IVF, ngaleyo ndlela, njengenqubo, i-anesthesia ayidingekile. Ngosizo lwamakhemikhali akhethekile angena emgodini wesibeletho ngokusebenzisa umsele womlomo wesibeletho, ama-embrasi akhulisweyo athuthwa.

Ukwesekwa kwesigaba sokuqapha

Yenziwa ngamalungiselelo e-progesterone. Kudingekile ukufakelwa okuphumelelayo kwebungu elifakwe emzimbeni ku-myometrium ye-uterine.

Ukuxilongwa kokukhulelwa

Lenziwa ngokusungula i-hCG engxenyeni yegazi labesifazane futhi lwenziwa kakade ngosuku lwangama-12-14 kusukela ngesikhathi sokusebenza. Isiqiniseko se-Ultrasound sokuphumelela kwe-IVF singenziwa kusukela ezinsukwini ezingu-21 ngemuva kokudluliselwa. Ngendlela, ivela kulo mzuzu (usuku lokutshala) ukuthi i-parameter enjalo ibhekwa njengesikhathi sokukhulelwa ne-IVF.
