Mu vitro feteleza (IVF) imaonedwa kuti ndi njira zonse zothetsera vuto la kusabereka. Chofunika kwambiri cha ndondomekoyi ndi kupeza mazira azimayi okhwima m'mimba mwa mazira ndi kupitiriza kukula kwa spermatozoa. Mazirawa amakula mu sing'anga yapadera mu chofungatira, kenako mazira ameneĊµa amatumizidwa ku chiberekero mwachindunji.
In vitro fetereza imagwiritsidwa ntchito pochiza mitundu yosiyanasiyana ya kusabereka, kupatula pamene chiberekero chakhala ndi kusintha kwakukulu kwa matupi, monga intrauterine fusion ya makoma.
Kawirikawiri, njira ya mu vitro fetereza imagwiritsidwa ntchito pochitira anthu okwatirana amene, patatha chaka chokhala ndi moyo wogonana nthawi zonse popanda kugwiritsa ntchito njira zolera, musaganize. Komanso, IVF imagwiritsidwa ntchito polepheretsa miyendo ya falsipi, kutayika kwa thupi la mazira ndi mazira, ndi spermatogenesis ndi kuperewera kwa mahomoni.
Ndondomeko ya mu vitro feteleza ikuphatikizapo magawo 4:
- Kukoka kwa ovulation ndi njira yothandizira ovulation ndi mankhwala kuti amasule mazira angapo panthawi imodzi.
- Kuthamanga kwa follicles - mazira okhwima amatengedwa kuchokera ku follicles (kupyolera mukazi), mwa kuika singano mwa iwo, momwe follicular madzi omwe ali ndi mazira amayamwa. Kupuma kwa follicles ndikopweteka kwa mkazi, kumachitidwa pansi pozindikira, popanda kugwiritsa ntchito anesthesia.
- Kulima mazira kumatanthauzira njira yoberekera ndi kukula kwa mazira. Pambuyo pa maola 4-6 pambuyo pa kutsekedwa kwa follicles, spermatozoa imayikidwa pa mazira, chifukwa cha ubwino wopanga feteleza kumayambanso kumagawa maselo.
- Kusamutsa mazira - njira yopititsira mazira pachimake cha uterine pogwiritsa ntchito catheter yapadera, yomwe imayambitsidwa kudzera mumtsinje wa chiberekero pafupifupi 72 maola atatha kuyamwa ma oocyte. Kawirikawiri, mazira 4 amachitidwa kuti akhale ndi mimba yaikulu. Njira yopititsa mwanayo imakhala yopanda kupweteka ndipo safuna anesthesia kapena anesthesia.
Kuchokera pa tsiku loyambitsirana m'mimba, makonzedwe apadera akulamulidwa kuti akhalebe ndi chitukuko chokhazikika komanso choyenera, chomwe chiyenera kutengedwa mwatsatanetsatane malinga ndi lamulo la adokotala.
Kuyamba kwa mimba kumatha kudziwika ndi mlingo wa chorionic gonadotropin pofufuza magazi masabata awiri pambuyo pa mazira adasamutsidwa ku uterine. Chorionic gonadotropin (HG) ndi yoyamba yokhala ndi mimba yokhala ndi mimba, yomwe imapangidwa ndi dzira la fetus ndipo ndi chitsimikizo chotsimikizira kuti ali ndi mimba.
Pakadutsa masabata atatu mutayika feteleza ndi ultrasound, mungathe kuganizira za mwana wamwamuna m'chiberekero.
Pambuyo pa umtro feteleza, mimba imapezeka 20% pa milandu. Pali zifukwa zingapo zomwe zingayambitse kulephera, zomwe zimakonda kwambiri:
- Kusakhala ndi oocyte kukula ndi kuyambitsa mphamvu ya ovulation;
- kuchitika kwa ovulation msanga;
- kusowa kwa mwayi wopezera mazira powatulutsa mapuloteni;
- zosafunikira kapena oocyte zabwino zomwe zimaperekedwa;
- N'zosatheka kuti umuna ukhale ndi umuna;
- ndondomeko ya selo logawana pakati pa mwana wosabadwa siyamba;
- mapangidwe a mazira oyipa;
- Kusamalidwa kwa mazira mu uterine.
Pamene sichiyambila mimba, mu vitro feteleza ikhoza kubwerezedwa. Pali milandu yomwe maanja ena amakhala ndi mimba pokhapokha atayesa 10. Chiwerengero cha zoyesayesa zoyenera za IVF chimatsimikiziridwa ndi dokotala pachifukwa chilichonse payekha.
Khalani wathanzi ndi wokondwa!
