Ukufakelwa kwesisu kumnye wexesha elibalulekileyo lokukhulelwa. Oku kungenxa yokuba umntwana ozayo unokubunjwa komzimba okwangaphandle kwimizimba yomama - emva kwesiqingatha seengcambu zikayise (23, i-haploid set).
Ngethuba lokumiselwa kwembungu, i-embryo iyafakwa kwisibeletho, ibe yindawo engqambileyo ye-mucous layer. Ngelo xesha, i-villi ye-embryo ingene kwi-mutersa ye-uterine, enokuthi ihambe kunye negazi elincinci.
Xa i-embryo iqhotyoshelweyo eludongeni lwesisu, kwaye oku kwenzeka kumaxesha ahlukeneyo kumfazi ngamnye, ngokuphindaphindiweyo ukususela ngomhla we-8 ukuya kwe-14 ngosuku emva kokuvuthwa. Ngeli xesha, umbungu usuvele unamaxwebhu amabryonic amabini - ngaphakathi nangaphandle. Ukususela kwiqabunga elingaphakathi, umntwana uza kukhula, kwaye ukusuka kwiphepha elingaphandle-i-trophoblast, eliza kubumba i-placenta kwikamva. Ngu-trophoblast oza kudlala indima ephambili ekuphuhliseni phambili kokukhulelwa: lujongene nokuphuhliswa kwezinto ezithile ezithintela umama ukuba ahlasele kwaye anqabe umntwana.
Kwisiza sokusungulwa kwembungu, izicubu ze-uterine ziba zihlazo, ziqokelela amanzi, i-lipids kunye ne-glycogen-le nkqubo ibizwa ngokuba yindlela yokuphendula. Kukho i siphene sendawo kwingqamane yomlenze wesibeleko. Ngokuqhelekileyo, ngaphambi kokuba ngomhla we-14 emva kokuvuthwa, le mpahla ivaliwe, kodwa ukuphuma kwegazi ezincinane kungenzeka, Endaweni yokuphendula ngokukhawuleza, ukubunjwa kweempahla ezininzi zepentecenta ezayo kwenzeka, kwaye ziya kuphuma.
I-IVF, i-embryo implantation ibaluleke kakhulu, njengoko iqinisekisa isiqhamo sokuqhumisa kwaye ibonise ukuba umfazi unokukwazi ukuthwala esi siqhamo. Oku kuthetha ukuba akukho phendulo yokulahlwa kwaye kukho amathuba aphezulu okukhulelwa okuphumelelayo.
Iimpawu eziphambili ze-embryo implantation zihlukaniswe zibe yi-subjective kunye nenjongo.
Izimpawu ezicwangcisiweyo zokufakelwa ziquka:
- intlungu, ukudonsa, ukubetha okanye ukusika kwisisu esezantsi;
- ubuthathaka, ukwesaba, ukucaphuka;
- uvakalelo lokubamba, i-scrapers kwisibeleko;
- uvakalelo lokukhathala kunye ne-malaise jikelele;
- kaninzi izibonakaliso zezibilini zokufakela izibilini zowesetyhini zichaza kunye nemeko yazo ngaphambi kokuya esikhathini.
Iinjongo zeenjongo zokufakela embryo ziquka:
- ukuphuma kwintsholongwane emfutshane okanye ukukhutshwa kwamanzi ngexesha lokuzaliswa kwembungu;
- ukwanda kwisebusuku yomzimba ukuya kuma-37.0-37.9 degrees. Kubalulekile! Ukwandisa izinga lokushisa ukuya kuma-38 nangaphezulu lingabonakalisa uphawu lwezinye izifo kwaye kudinga ukubonisana nodokotela. Xa kufakwa, ubushushu buhlala buncinci;
- ukufumanisa i-hCG egazini kunye nomchamo - ukufumanisa le hormone kuyisiseko sovavanyo lokukhulelwa. Esi sibonakaliso esibaluleke kakhulu, kwaye sibonisa ukuphunyezwa ngokuphumelelayo.
Nangona kunjalo, kubalulekile ukuba uqaphele ukuba ukushisa komzimba ngexesha lokufakelwa kombungu kungasoloko kuqhelekile, kwaye kwanokuncipha. Kwakhona, ukuphawula akuvumelekanga. Ngokuphindaphindiweyo ngokuphindaphindiweyo kwabasetyhini ubuhlungu xa kufakwa imbryo kwisisu esezantsi, kwendalo kunye nokuqina.
Kubalulekile! Xa i-embryo ifakwa, ukubonakala kwinto elula, ixhomekeke, ayininzi. Ukuba uqaphela ukukhutshwa ngokuxhomekeka kwimihlobo yesisu, ehambelana nentlungu kwisisu esezantsi, kha wuleza ugqirha ugqirha! Oku kungaba ngumqondiso wokuqala wokukhipha isisu. Ngokukhawuleza uphendulela uncedo, uvumelekile ukuba ugcine umbungu kunye neyakho
Kufanelekile ukukhumbuza ukuba ngexesha lokumiselwa kukho uhlobo "lokukhethwa kwendalo": ukungenakukwazi ukuqhubeka nokuphuhliswa, amaqanda azaliswe ngumhlaza unqatshelwe ngumzimba womama kwaye akafaki kwisisu. Oku kuvimbela ukuphuhliswa kweembryo ezingaphantsi komntwana kumntwana, ekubeni ukugatywa ngaphambi kokumiselwa kuphephile, akusongeli ubomi kunye nempilo kamama. Kodwa ngokuchaswa ezininzi ngaphambi kokumiselwa, kufuneka kuhlolwe uvavanyo olupheleleyo lwezonyango ukuchonga nokuphelisa izizathu zokuphulwa kwenkqubo.
