Fertilization ndiro danho rokutanga rinofanira kuitika kuti riite mwana! Mukutaura kwakajeka, kufungidzira kunowanikwa apo chirume nezai zvinobatanidza kuumba embryo. Kuti murume nemudzimai vaite mwana, unoda huropi, chibereko, fallopian tubes, chirume uye mazai ane utano .
Basa Rokunyora
Muchivharo, pane chimwe chinonzi follicle. Iyo follicle isaga yakazara-mvura inenge ine dyo rimwe uye masero anogadzirira egg kuti atange kuve nekukura.
Apo mukadzi ane nguva yake, pane boka rose re follicles muovary iri kugadzirira kukura. Iyi follicles, inozivikanwa se antral follicles iri pakati pe2 ne10mm muhukuru.
Uropi hunoita hormone inonzi Follicle Stimulating Hormone (FSH). FSH inotaurira follicles muyvary kuti ikure uye iwedzere. Mumwe anotanga kuva anenge 20mm uye mamwe ose akaparara. Ikoko hupenzi hukuru hunoita estrogen inotaurira kubatana kwechibereko ichikura uye kugadzirira kugadzirirwa. Uropi hunoita nehomoni inonzi Luteinizing Hormone (LH) - izvi ndizvo zvinowanzoonekwa neyvulation predictor kit . LH inongovapo mumuviri kwezuva rimwe chete mwedzi mumwe nomumwe.
Ovulation uye Kusunungurwa kweEki
Inenge maawa 24-36 mushure mekunge LH inoratidzika, ovulation inowanikwa uye egg inosunungurwa kubva kuvhavha. Evha inoda kutorwa ne fallopian tube apo mbeu inogona kuiwana. Ivha rinoberekwa rinonzi embryo .
Mazuva mashanu mushure mekuita, mazai ari pamusana weBlastocyst anokandwa mukati mechiberekwa, apo inoda kuiswa mukati meganda. Kana izvi zvikaitika, mimba yekuita pamuviri inoshandiswa uye nguva inotevera inoshaikwa.
Nzira yeMuteresi
Fertilization inowanzoitika muhutoripian tubes yemukadzi nguva pfupi mushure mokunge ovulation kana chirume chichiita kuti chive chibereko chekubereka.
Panguva yekuita zvepabonde, mamiriyoni emadhimoni anotenderera kuburikidza nehutano hwemukadzi asi mwana mumwe chete unogona kupinda kana kuvhara, mazai. Pakarepo, mushure mokunge mazai nemumhino vasangana, masero anotanga kusanganiswa pamwe nekuparadzanisa izvo zvinotanga kuumba genetic DNA kuenzanisa uye zvepabonde (mukomana kana musikana!) Kwevana remangwana.
Kana imwe mbeu isina kukwanisa kupinda muii, iyo yai inopinda nepamuviri uye inoparadzaniswa. Mushure maizvozvi, mahomoni ako achadzoka kune akangwara uye muviri wemukadzi unotanga kukanda ruvara rukuru rwechibereko kuburikidza nekuenda kumwedzi.
Kana imwe nguva mazai akashongedzwa, inobva yasvetuka mukati mehubhu uye mapiritsi mukati mechibereko , kutanga pamuviri. Vamwe vakadzi vanogona kucherechedza (kana kuti kubuda kweropa) kwemazuva 1 kana maviri kumativi ekuzorora. Dzimwe nguva mazai anogadzirwa anowedzera kunze kwechibereko, zvakadai se fallopian tube kana chirvix , iyo inozivikanwa se ectopic pregnancy.
