In vitro fertilization (IVF) inofungidzirwa senyika yose uye nzira yakanakisisa yekugadzirisa dambudziko rekushaya vana. Chinokosha chemuitiro ndechokuwana mazai echikadzi akakurumbira kubva mumapapiro omukati uye nekuwedzera kuwedzerwa kwemurume wepermatozoa. Mazai aya anogadzirwa anowedzera mune imwe svikiro chaiyo muine incubator, saka mazamu aya anotamirwa muchibereko chairo zvakananga.
In vitro fertilization inoshandiswa kurapa maitiro akasiyana-siyana ekushaya simba, kunze kwekuti kana chibereko chikava nekushanduka kwemaatomical, zvakadai se intrauterine fusion yemasvingo.
Kazhinji kacho, nzira ye in vitro fertilization inoshandiswa kurapa vakaroorana avo, mushure memakore eupenyu hwepabonde nguva dzose pasina kushandisa zvekudzivirira, havafungi. Uyezve, IVF inoshandiswa pakudzivirira kweiyo fallopian tubes, yakaputsika manzwiro ematope uye mavhai, ne spermatogenesis uye hormonal infertility.
Nzira ye in vitro fertilization inosanganisira zvikamu 4:
- Hormonal stimulation ye ovulation ndiyo nzira yekukurudzira ovulation nezvinodhaka kusunungura mazai akawanda panguva imwe chete.
- Nguva ye follicles - mazai akakura anobviswa kubva ku follicles (kuburikidza nemudzimai), nekuisa nenyuchi mukati mavo, iyo iyo follicular fluid ine mazai inoyamwa. Kuvhara kwema follicles kunorwadza kwemukadzi, unoitwa pasi pekucherechedza kwechidimbu, pasina kushandisa anesthesia.
- Kukura kwemazai ndiko kutarisa kwemaitiro ekugadzirisa uye kukura kwemazai. Mushure memaawa mana kubva maawa matanhatu mushure mokuputika kwemapaupiki, spermatozoa inowanikwa pamazai, semugumisiro wekubudirira kwekuberekwa embryo kukura kunotanga nekuparadzanisa masero.
- Kudhindwa kwemazai - iyo nzira yekuendesa mazai muuterine cavity achishandisa catheter chaiyo, iyo inotanga kuburikidza nemugero wechibereki anenge maawa 72 mushure mekugadzirwa kweoocyte. Kazhinji, anenge mashizha mana anotorwa nokuda kwehutano hukuru hwokuzvitakura. Iko kushandiswa kwekuberekwa kwembryo kunosuruvarisa uye hakudi kuti anesthesia kana anesthesia.
Sezvo zuva rekuendeswa kwemuviri, kugoverwa kwakakosha kunorayirwa kuti urambe hunobudirira uye hunobudirira huri kubudirira, iyo inofanira kutorwa zvakasimba maererano nemirairo yachiremba.
Kutanga kwepamuviri kunogona kuongororwa nehuwandu hwe chorionic gonadotropin nekuongorora ropa masvondo maviri mushure mekuberekwa kwaiendeswa kune uterine cavity. Chorionic gonadotropin (HG) ndiyo yekutanga yakakonzerwa nehutachiona, inoberekwa ne fetal egg uye chiratidzo chinotendwa chekusimbisa kuberekwa.
Makore matatu apfuura mushure mekuvhara mazai mukati mehutachiona ne ultrasound, unogona kutarisa mucheche mubereki.
Mushure mokunge in vitro fertilization, pamuviri inowanikwa chete mu20% yemhosva. Pane zvinhu zvakawanda zvinogona kutungamirira kukundikana, izvo zvinowanzoitika ndezvi:
- kusabatwa kwe oocyte kukura nehommonal stimulation ye ovulation;
- izvo zvinoitika nguva isati yasvika ovulation;
- kusava nekukwanisa kwekuwana mazai mukuputika kwe follicles;
- kushaya kukodzera kana hutsika hwakanaka hweoocytes inowanikwa nekuputika;
- kusakwanisika kwekugadzirisa mumumvuri pathologies;
- Iko kushandiswa kwemajekesheni ekuparadzanisa kwema embryo hakutanga;
- kuumbwa kwemaambuki ehurombo hwakanaka;
- asina kubudirira kuiswa kwemazai muuterine cavity.
Kana kusati kwatanga kutora pamuviri, in vitro fertilization inogona kudzokororwa. Kune zviitiko izvo vamwe vakaroorana vane pamuviri mushure mokuedza 10. Nhamba yekuedza kweVIV inoshanda yakagadziridzwa nachiremba pane imwe nyaya imwe neimwe.
Iva noutano hwakanaka uye ufare!
