Ivha inoberekwa inoita nzira yakaoma kupinda muchibereko - nzvimbo iyo ichakurira munguva yose yekuzvitakura. Muchibereko, mazai anopinda mudanga re blastocyst. Blastocyst ibhola rakazara nemvura. Icho chinyorwa chekunze cheblastocyst chichapedzisira chichikura mumapatenta, uye masero mukati anobva ava mucheche. Iye zvino anofanirwa kupindira muitiro, izvo zvinoreva kumubatanidzwa kwechibereko chechibereko. Icho chiri shure kwekupedzwa kwekugadziriswa kuti kuberekwa kunofungidzirwa kuti kwasvika.
Migomo ye embryo inogadzirwa
Pane imwe mubereki, embryo iri musina kusununguka kwemazuva anoverengeka, uye iyo inogadziriswa inotanga pakarepo. Izvozvo zvinonzi mazai ekugadzirisa mahwindo zvinouya pamazuva 6-8 mushure mekuvhara. Kusimwa kwemukati mumadziro emuviri kunowanikwa musi we5th-10 mushure mokuberekwa. Imbryo inofanira kunyatsobatanidzwa nemuviri weamai. Paavhareji, embryo inoda mazuva gumi nemaviri kuti iite zvakasimba mumubereki. Pane imwe nguva iyo embryo inosungirirwa pachibereko, mukadzi angave ane kubuda kwechiropa kuduku. Izvi zvinokonzerwa nekubatanidza kwembryo kusvika pachibereko. Mukati iyi nguva yose kune mikana yakakura yekusununguka kwepamuviri.
Kuti muve nepamuviri mabudiro mumuviri, vakadzi vanofanira kufanana newindo rekugadziriswa, kugadzirira kwechibereko kuti vagamuchire embryo, uye kuvapo kwei ovum yakazosvika pakero ye blastocyst. Mushure mokunge blastocyst yakabatanidzwa, kuumbwa kwebumbiro rakananga kunobva mumuviri wamai. Iye zvino vane ukama hukama hwepedyo nemumwe.
Nei pasina embryo inogadzirwa?
Sezvazvinozivikanwa, inenge 40% yeBlastocysts iyo yakabudirira kupinda muchibereko haisi kuiswa. Chimwe chezvikonzero izvo embryo inorambwa ndeye kuputsa mu endometrium - iyo inonzi iterine membrane. Iyi membrane inogona kunge isina kuwandisa zvakakwana kune blastocyst. Kana kuti pane chero kukanganisa. Kazhinji, kubvisa pamuviri ndiko kukonzera kusakosha mu endometrium. Somugumisiro wekusakanganiswa kwakadaro, kuora mwoyo kunowanikwa. Muchiitiko ichi, vakadzi vazhinji havatombofungi nezvekuita pamuviri, nokuti mazai evha anogadzirwa nemwedzi unotevera.
Kurongeka kwemasamu
Kuenzanisa kwemakirusi anoshandiswa makiriniki anoshanda muIVF fertilization. Kliniki yega yega ine zvinyorwa zvayo. Zvisinei, yakawanda pane iyi ndeye alphanumeric classification.
Nzvimbo yacho inonyanya kuongorora kunaka uye kutaridzika kwembryo. Icho chinonyanya kukoshesa muhutano hwemasumbu pazuva rechipiri nerechitatu rekusimudzirwa nhamba yemasero, pamwe nehuhu hwavo.
A qualitative embryo inofanira kuva nenhamba inotevera yemasero:
- kwemazuva maviri-kubva 2 kusvika ku 6 masero;
- kwemazuva matatu - kubva 4 kusvika ku10 masero;
- kwemazuva mana - anopfuura 8 masero.
Mifananidzo iri muhutano inoratidza hukuru hwe blastocyst, pamwe chete nechikwata chekuwedzera. Kune zvikamu 1 kusvika ku6. Mune mamwe makiriniki, ini ndinoratidzawo nhamba yemasero ari nhamba.
Tsamba yokutanga inoshandiswa muhutano inoratidza hutano hwemukati masero esero, iyo inonzi embbryo inokura. Inogamuchirwa kusiyanisa zvikamu zvinotevera - A, B, C, D, iyo A ndiyo yakanyanya kunaka.
Tsamba yechipiri inoratidza hutano hwe trophoblast - ichi ndicho chekunze kweblastocyst. Ndicho chiyero
Kushandisa kusarudzwa kwemazii, nzvimbo dzekudzivirira mafungiro dzinogadzirisa zvakananga sero iyo inogona kuzvibatanidza pachayo epithelium yebereki nenzira yakanakisisa. Icho kubva kwaari kuti hutano hwakanaka uye huzere huzere huchakudziridza. Mushure mekugadziriswa kwegadziriro kwapera, kushandiswa kwebasa rekuberekwa mukati memamai kunotanga.
