Yenzeka umbungu esibelethweni. Kwenzekani ngemuva kwekwakheka kwembewu?

Emva kokukhulelwa, iqanda elindela indlela eside futhi nzima zokwakha ku le endometrium lesizalo. Ngokwezibalo, abantu abangaphezu kwengxenye babo abazange zenzeke. Kulokhu lowo wesifazane engathandi ngisho ukwazi ukuthi kukhona baqala ukuvela impilo entsha.

Ngokwesilinganiso, zokwakha umzila umbungu kwenzeka ngesonto emva kokukhulelwa. Sonke lesi sikhathi, uhamba Iqanda eduze amashubhu fallopian futhi limatasa asathuthuka, ukulungiselela lo mcimbi. amahora 20 emva kokukhulelwa, ihlukaniswe yaba izingxenye ezimbili. Ngemva kwalokho egg uye ngokuthi i zygote. Phakathi nohambo lwakhe, wabhekana ngokuphumelelayo ngokuphindaphindiwe yahlukaniswa ukwakha ibhola esiqinile amaseli amaningi. Lapho inombolo yabo ifinyelela 16-32, le zygote iba Morula. Uma ihlukaniswe yaba izingxenye ezimbili, enye ithola amawele. Lapho Morula ifinyelela kwesibeletho, yakhiwa liphuza lamaseli 64. Ezinye zazo ngeke zibe umbungu, bese okunye uyomenzela placenta nemisipha.

Morula kancane kancane liphenduka isibani egcwele uketshezi. Ngemva kwalokho, kuba i-blastocyst. Isendlalelo ebusweni iba amaseli nge placenta, nalabo ezingaphakathi, zibe umbungu. Kungenxa esigabeni blastocyst iqanda eselivundisiwe ifika kwesibeletho.

Lokhu kwenzeka ngokuvamile, kodwa uma le amashubhu fallopian , ngoba noma ngabe yisiphi isizathu, ingahambeki, zokwakha umzila umbungu kungenzeka okulungile odongeni yabo. Kufika ukukhula komntwana ethunjini, okuyinto ingozi hhayi nje ngobe kutawutfutfukisa nempilo yokuzalana kwabantu besifazane, kodwa futhi impilo yakhe.

Kanjani ngempumelelo kudlule yenzeka umbungu esibelethweni kuxhomeke ekutheni isilungele lona wokugcina. Ukuthola kuwo, lo-blastocyst akha kwezinsuku ezimbalwa ngaphezulu ukubhukuda khulula. Ekulungiseleleni kwesibeletho ngoba yenzeka ngendima eziyisisekelo eyadlalwa progesterone hormone.

Kubalulekile kakhulu ukujiya kanye nozwela endometrium, kusukela imibungu baqala ukuhlanganyela naye, hhayi ezifakelwa, uma ayikalungi salokhu. Isikhathi yimpumelelo kakhulu ukwethulwa blastocyst esibelethweni ziyinkathi kusuka 20 kuya 24 umjikelezo wokuya esikhathini. Endometrium ngalesi sikhathi Lesi sifo siphatha kakhulu kuwo, ngoba zazikhiqiza izinhlobo eziningi ezinkulu izinto asebenzayo.

Blastocyst ngesikhathi yenzeka lingena ke ahlangene asesibelethweni Ukubhidliza kwenzeka ekukhishweni kwegazi. Ngezinye izikhathi endometrium okunomsoco anele wakhe, khona-ke kwesisu kwenzeka.

Uma yenzeka umbungu asiphumeleli, khona-ke okukhipha ngokusebenzisa sangasese. Ngokwezibalo, u-40% blastocysts, abaye bawela kwesibeletho, kungukuthi ukusebenza ngo mucosa yayo.

Uma yenzeka kuphumelela, placenta ucala kutfutfukisa ukuthuthukiswa umbungu nokukhulelwa i-hormone hCG. Kudingeka mayelana 2 amaviki athole ukusizakala niqinile kwesibeletho. Phakathi nale nkathi, kwesisu kungenzeka, kodwa cishe ngeke, ngokushesha ngemva yenzeka.

Kakade izinhlamvu ziqala ukwakheka ezinye kwezitho izinhlelo umbungu. Kulezi amasonto amabili sisengakwazi ukuba bahlukana baba izigaba ezimbili kanye kumiswa izithelo ezimbili. Uma kwenzeka kamuva etholwe twins Siamese.

Omama abaningi abalindele abanesifiso bafunde ukuthi ukuthi yenzeka livelile. It kuvela ukuthi zikhona ezinye zezimpawu ezikhombisa ukuthi lokhu okwenzekayo. Ngakho, zokwakha umzila we-embryo: Izimpawu:

• kungenzeka ukubeka amabala;

• ishadi of lokushisa lomzimba basal siyenzeka nokwehla elibukhali yayo (usaba yenzeka) ngalolu suku.

Lokhu kungenxa yokuthi ngemva ukwethulwa blastocysts phakathi endometrium, ngokwesilinganiso, kwakubikwa ukukhululwa ngokushesha i-estrogen, okuholela ukwehla kwezinga lokushisa. Phela, kwakungenxa yokunithanda kuye esigabeni sokuqala lomjikelezo uphansi.

Ngakho, zokwakha umzila we-embryo kuhambisana ukwehla lokushisa lomzimba basal ukopha abanye okuncane. Ngokwezibalo, uphumelela kuphela 60% blastocysts, kuyilapho okukhipha asele. A zokugula esiyingozi liwokunamathiselwe yayo odongeni tube fallopian ngesikhathi isimiso salo. Okuhambayo nokuthuthukiswa iqanda eselivundisiwe kuthatha cishe isonto. Ukuze yenzeka ngempumelelo ukuzwela kubaluleke kakhulu futhi ukujiya endometrial.
