Kudzokera kuchikoro, takaudzwa kuti kuberekwa kwehupenyu hutsva kunoitika semusangano we ovom uye chirume. Nokudaro, mabasa ei muhupenyu hwemadzimai ose akaoma kufungidzira. Inobva pauwandu uye hunhu hwemaii ayo hutano hwehutano hwevakadzi hunoenderana.
Iko inogadzirwa kupi?
Amai eki anoumbwa mu ovarian follicles. Mazai mavari ari munharaunda yakadzika yedumbu remuviri: imwe iri kurudyi uye imwe iri kuruboshwe. Izvozvo zvinowanikwa mumapapiro emusikana ari mudumbu, uye panguva yekuberekwa, nhamba yavo inenge mamiriyoni 1.5 mamiriyoni. Munguva yehupenyu, nhamba ye mazai haibatsiri, asi, pane zvinopesana, nguva dzose inoderedzwa.
Oogenesis
Nzira yekuita mazai inonzi oogenesis. Oogenesis inogona kugoverwa muzvikamu zvitatu:
- Kuberekwa kwe follicles (kunoitika apo musikana ari mudumbu reamai).
- Kukura kwe follicles (kubva pakuberekwa kusvika pakupera).
- Kusimwa kweiki (kutanga nekupera).
Pachigarire chekusimwa kunofanira kukurukurwa zvakadzama. Kubudirira kweii kunotanga musi wekutanga wemwedzi, apo uchiri kukomberedzwa ne follicle. Pakutanga, uwandu hwehutori hunenge 1-2 mamita. Mumufananidzo wakakura, ukuru hweii mu follicle inenge inenge mamita makumi maviri. Panenge pazuva rechigumi nemana rehupenyu, egg inoparuka. Nguva iyo mazai anobva mumapurisa anouya. Mushure maizvozvi, anotanga kufamba nemugwagwa unoenda kumurume. Nzira yekubudiswa kweii inonzi ovulation.
Ihwo hutachiwana hwehupenyu hunove huri huno hunopfuura maawa makumi maviri nemasere, uye iyo nzira iyo mikana yekudyara inoramba ichiderera. Kana kudyara kusina kuitika, zamai anofa. Kazhinji, panguva imwe neimwe yekutenderera, mukadzi anowana rimwe diki rimwe nerimwe.
Nzira yekuvandudza hutano hweii?
Zvinosuruvarisa, mubvunzo uyu unowanzobvunzwa unowanzosiyiwa usina kupindurwa. Sezvo mutemo, hazvibviri kunatsiridza hutano hwemazai, chinhu chikuru ndechekuvimbisa kuti huno huno huri kuipa. Mushure mezvose, mazai evakadzi aripo mumuviri wake hupenyu hwake hwose, panguva iyo ivo vanobatwa nemhando dzakasiyana dzezvinhu zvakaipa. Pakati pavo - kushungurudzika, hupenyu hwakaipa, tsika dzakaipa nezvimwe zvakadaro.
Kuti musashusha kuora kwehutano hwemai masero emukadzi, inofanira kuva:
- kutungamirira nzira yakarurama yehupenyu, kurega tsika dzakaipa;
- kudzivisa mamiriro ekumanikidza;
- kudya zvakanaka.
