Kuberekwa kwehupenyu hutsva inzira yekudedera uye inotarisirwa, inotanga nekudyarwa kweii neine chirwere chemuviri. Zygote inoguma inopinda mumatanho ekufambira mberi kusvika pakuumbwa kwe fetus uye kuberekwa kwomunhu mutsva.
Fertilization uye kubata pamuviri - ichi chinhu chinonyanya kukosha chaunoda kugadzirira nemutoro wose, nokuti izvi zvinoenderana nehutano hwemangwana mwana. Mucherechedzo unofukidza mavhiki maviri ekutanga ekudzivirira kubva pabonde kusvikira pachinonoka kuenda kumwedzi uye zvimwe zviratidzo zvepamuviri.
Nhanho dzekuberekwa
Nzira yekugadza inosanganisira zvikamu zvitatu:
- Kukurukurirana kwakanyanya uye kutenderera kweii uye chirume.
- Garai mitambo yekubata uye kushandiswa kweii.
- Kupindira kwehuta ye ovum shell uye syngamy.
Chii chinoitika mushure mekudyarwa kweii?
Pakati pezvakawanda zvepermatozoa, imwe chete inosvika ku ovum, inopinda muhombe yaro uye inoisimudza mubazi re ampullar ye uterine tube. Nekupindira kweviri spermatozoa, hutachiona hutatu hunoumbwa, huchaparadzwa. Kupinda muzhi kunogona kungova nemunhu mumwe chete, musoro unoramba uri mukati, uye muswe nepakati chikamu zvinoparadzwa. Mushure mokunge musangano wekromosomes unosvika 46. Zygote inoumbwa - iyo inicellular stage ye embryo (danho re zygote rinotora maawa 26-30). Zygote inopatsanura, kwemazuva matatu iyo inofamba ichifamba nechembera uye inopinda mumuganda werinterine, iyo inowirirana nehutachiona hunoshandiswa (iyi inonzi inonzi implantation, inowanikwa musi we6th-7 wekuberekwa). Iyo pfupa inoguma yakagadzirwa nemasvondo makumi maviri nemasere kubva pakuberekwa, inoita mabasa emapapu, tsvete uye chiropa kumucheche - kubva pamakanda kusvika kumucheche ndiyo midziyo inoumba tambo yembilical.
Zvinotora nguva yakareba sei kudiridza?
Zvinotora nguva yakareba sei kudiridza? Fertilization inoitika mushure mekuvhara, mukati meawa gumi nemaviri. Nguva yegadziriro yacho, apo kubereka kunoitika mushure mekuberekwa, kunobva paupenyu hweii, iyo ine nguva shoma shoma kupfuura spermatozoon (maawa gumi nemaviri), iyo inogona kusimbisa hupenyu mumuviri wemukadzi kusvika mazuva mashanu. Nhanho yehuta ndeyemamilimita gumi neminiti paminiti, saka inosvika kumazai, inogona kunge iri awa mushure mekuvhara. Nokuti nguva yekutanga kweivulation haina kunyatsofanotaura, kubata pamuviri kunogona kuitika mazuva 1-7 mushure mokuita zvepabonde.
Kubata pamuviri uye kubereka kunoitika sei?
Zuva rekuberekwa uye zuva rekuberekwa hazvienderani mumatambudziko mazhinji. Chero kana hupombwe hukaitika panguva yekuputika, zvino mazuva aya achabatana, asi anogona kunongedzerwa chete munyaya yehupenyu hwepabonde husina kukwana.
Intrauterine insemination
Ikoko kunewo intrauterine insemination. Iine chimiro chechimiro uye inowanikwa munyaya yekuderera kunononoka muhuwandu hwekugadzira hutachiita hwemurume wemurume, kana mukadzi wacho ane utano. Uyezve, intrauterine insemination inowanikwa pakusimbisa kuipa kwemuviri wechibereki pamusana pepermatozoa, iyo inotangwa
Iko kuedza kweWMO kunodzokororwa panguva yekutenderera 2-3 nguva, chirume chinoshandiswa kurapwa. Mushure mokuwedzera kubereka kwehuta, inorohwa zvakananga munzvimbo yechibereko, iyo inonyanya kuderedza kure kure neii. Kuedzwa kwekuita pamuviri kunofanira kuitwa mavhiki maviri mushure mekuita. Kana iwe uchipedza nenguva uye nezvose zvakasikwa zve intrauterine insemination, kubata pamuviri kunowanikwa mu80% yematambudziko.
