Sezvo pakusangana kunoitika? Kunyange gumi apfuura ichi kunogona chete zvokufungidzira, asi zvino tichibatsirwa supertechnologies azvaiitwa zvinogona kunyange kuonekwa.

Chokutanga, ngatirambei pakutanga kwacho - iri kuibvisa pakati oocytes. Ivo vachiyaruka ari ovaries, izvo varerei zvose zvakafanira zvinhu. Pamusana kwavari, kunomutsa pfungwa kukura uye kuibvisa pamusoro oocytes. Kwete kure shure uye follicle kuti runopoteredza zai - uyewo vachishingaira kukura, uye watsemuka uye zvabudiswa zai mukati abdominal mhango zvasvika imwe saizi. Panguva ino, kwemakemikari omuviri maitiro anonongedzera masa fanera pamusoro fallopian sepombi kuti zai atova kunze uye inguva "adzoke kuboka." Fanera, sezvinoita vacuum, nokufamba ayo faibha kunokwezva zai iri fallopian chubhu. Kana paine chikonzero chinoita urume uye zai havasi mberi mune dumbu, asi vanoramba vari mutopota, ipapo ichi inonzi Tubhari pamuviri kana ectopic. anomaly ichi, umo panguva kukura zygote chubhu ruptures, saka vanachiremba akabvisa mudumbu kwakadaro.

The fallopian chubhu ndiyo zai kazhinji uye panosangana urume uye chirongwa muchangosangana. Izvi ndiyo nguva chaizvo vasanonoka, sezvo zai anorarama kwerinenge zuva, uye urume zvikanzwika zvinokosheswa nzvimbo kwemaawa anenge matanhatu.

Panguva iyi kuwana chete akasimba, zvikuru musoro dzisingaoneki. On munzira vakasangana vakawanda nezvipingamupinyi. Mumwe wavo - the remuromo madzihwa, rinova wakawondereiko kudai mazuva ose ari kusachinja-chinja panguva kusunungurwa zai. Ndokusaka vakadzi kunzwa panguva ovulation kuwedzera kusangana nekutsi kwemukadzi mwando, zvishoma yakakura zvinoverengeka chiedza segirazi buditsa. At muromo urume musoro dzinokosha zvinhu kuti kuiparadza zai rusvingo. muchangosangana asati kunoitika, vamiririri izvi anosangana nemumwe uye gwara kuzarurwa dzisingaoneki nechomukati. In vhidhiyo, zvinoitika zvakasimba zvakakwana, kana urume mukati zai chakakombama zvavo zononoka inofamba iri muswe. Izvi unoumba tanga mudumbu fomu - zygote. Nechekare panguva iyi mudariro dzisingaoneki, kubatanidzwa nomumwe pamwe chete, anounza 23 okutodza yokugara mashoko, iyo pamwe chete navamwe zai okutodza achasarudza kuti pakuzadzisa azvarwa. Kana urume hwapinda mukati zai, goko zvinoramba zvichitowedzera kukosha gobvu, izvo kunotadzisa mberi kupinda pakati dzisingaoneki.

Kamwe pakusangana kunoitika, hormone hurongwa nokukurumidza kupindura ezvinhu anochinja. The muviri anopiwa chiratidzo kuti pakunambwa kwakaitika. Zvinoita kunzwa muchangosangana? Pasinei Zvaiita nehasha, asi kwete nenzira panguva yokunambwa, muviri haazivi nezvazvo. Chete pashure pachava mamwe matanho, muviri mumwe mukadzi wacho uchatanga kunzwa vepakutanga zviratidzo pamuviri.

Kana pakusangana harina anowanzoita kuti zygote kunotangira kuti fallopian chubhu kuti dumbu, riri pasi pokudzora mahormone kare kugadzirira kugamuchira embryo. Zvinotora anenge mazuva matanhatu, uye zygote "anosarudza nzvimbo" pezvizuva achiri mudumbu. Endometrium panguva ino yava kwazvo gobvu, anongoremberera - chero nzvimbo akagadzirira kutora zygote. Kazhinji kacho wanamatira pamberi kana rwemberi parusvingo dumbu, uye pashure mumwe vhiki zygote iri kunyudzwa zvachose mai doro rukoko. nguva ino yose embryo chikafu chii kusvitsa zai follicle - zvinobatsira zvinovaka muviri - kwemafuta uye mapurotini. Kamwe pakusangana kunoitika, uye achabatanidza kuti dumbu, kuti placenta kachitanga uye anotanga mwedzi mipfumbamwe- gestational nguva pakukura kwemwana.
