Kanjani ekuhlaleni kwesisu senzeka: kancane iwele, ukufinyelela ikhodi bese ukungazali

Kukhona ubuhle ekhethekile sokukhulelwa. Isithembiso impilo entsha emzimbeni womuntu wesifazane kubukeka kakhulu ukuphila-evuma. izinqubo eziyinkimbinkimbi kukhona e- zonke izigaba "isimo ezithakazelisayo." I ngqo usuku owesifazane ebamba isethi akwenzeki ngaso sonke isikhathi. Udokotela ubhala kumadokhumenti ngosuku lokuqala lokugcina esikhathini njengoba ekuqaleni sokukhulelwa. Nakuba empeleni Ukuphila okusha kuqala cishe amasonto amabili kamuva irekhodwe ephepheni ithemu. Kanjani ukukhulelwa?

Isigaba ukulungiselela

Konke kuqala nge-ovulation. Inyanga ngayinye ku esibelethweni ilungiselela ukuba adedele "ukhetho" ezimbalwa, kodwa amaqabunga ngokuvamile iqanda elilodwa kuphela, ngezinye izikhathi ezimbili. Uma kuzodingeka angaphezu kwelilodwa, futhi womabili avundiswa, ke ozozalwa twins anobuhlobo. Basuke, ngqó, amaphahla akuzona nhlobo. Futhi kubonakala sengathi bayoba njengebhuqu izingane ezimbili kubazali abafanayo.

izingane 16 ngesikhathi?

Injani ukuzalwa kwamawele kuyisenzakalo esikhethekile kweqiniso? Njenganoma iyiphi enye, kodwa ngasizathu simbe esikhathini esithile inani imibungu efanayo isimiso sezakhi zofuzo. Kwakucatshangwa ukuthi umuntu angase abe amaningi njengoba 16 ngesikhathi amawele, njengoba at the stage of 16 blastomeres, isitokisi ngasinye kungaba zisenza sibe lonke umzimba. Kodwa lenqwaba twins izifo zivamise ukwenzeka ngenxa yokwelashwa ukungazali, ngoba owesifazane ebamba abantu izingane engaphezu kwemibili ngasikhathi sinye akukhona evamile.

emacaleni angakajayeleki

By the way, ngokuphambene nenkolelo evamile, umfana nentombazane akukwazi twins kweqiniso, ngoba amadoda nabesifazane abaseBhayibhelini ahlukene zofuzo, iqoqo amawele afana ncamashí. Okuwukuphela kwakuthiwa kungenzeka: babafana ababili Izakhi zofuzo, kodwa esinye sazo ukuthuthukiswa natal okungahambanga kahle, futhi amantombazane kwakhiwa phansi singahlangabezani samanje. Lezi "amantombazane" kukhona ezingenalusizo.

Ukufinyelela kunqatshelwe

Kanjani ukukhulelwa? Ngemva kokudedelwa ova tube fallopian, kungaba ukuhlangabezana isidoda okulindile. Kodwa ngokuvamile nezigidi zabangane babo. Akuwona wonke umuntu angabona zalisa yezinyoni. Ososayensi bathole ukuthi amaqanda ngalinye has a ethile "ukufinyelela ikhodi", esizibonakalisa isakhiwo chemical amaprotheni emaphethelweni yangaphandle. Uma isidoda ikhodi "efanele" phezu emvilophini, lo sokukhulelwa kungathatha indawo. Ngemva Ukungena amaseli besilisa ku iqanda ingasasebenzi futhi ayitholakali kweminye "ukhetho".

basola biochemistry

iseli zabesifazane is ngakho wahlela ukuba ngaphambi kokukhulelwa ke ayiphelele - inqubo meiosis iphela kuphela ngemva nokuxhumana isidoda. Uma umhlangano okufanelekelayo "umlingani" ingekho, iqanda uyabhujiswa, isimo hormone - nokuya esikhathini kuqala. Ukwazi kanjani ekuhlaleni kwesisu senzeka, kuyasiza ukuchaza ezinye ukungazali lemibhangqwana lapho abalingani efana ezimbili ziphilile. Ezimweni ezinjalo, indoda nomfazi azivumelani ezingeni kwamakhemikhali. Uma ukudala umndeni nabanye abalingani, abantwana elingangena ngokuphepha ozalwa kokubili.

Ngo inqubo nje ebamba isisu kukhona okuningi izimfihlo. Asazi yonke imithetho okwenzekayo. Kodwa kunento eyodwa ecacile - kudingeka izifundo okwengeziwe okuzala. Khona-ke bazokwazi engasiza imibhangqwana ukuhlupheka nenzalo.
