Ukufakelwa kweqanda le-fetal kulandelwa ukuphuma kweqanda le-fetal kunye nohambo lwayo olude kwi-tube ye-uterine ukuya kwi-uterine cavity. Le nkqubo ithatha malunga neentsuku ezintathu. Olunye iqanda ludlulela kwisibeleko ekufuneni indawo yokumisela. Kwaye ngosuku lwesikhombisa emva kokuchumisa kwe-blastocyst kuqala ukuqaliswa kwi-epithelium yesibeleko.
Kwaye inkqubo yokuzisa iqanda lomntwana ekudongeni kwesibeletho kuthiwa ukufakwa. Kodwa musa ukucinga ukuba oku kwenzeka ngokukhawuleza. Isikhathi sokuncedisa iqanda lomntwana sele li malunga neeyure ezingama-40.
Ngamanye amaxesha kukho umonakalo omncinci kwi-mucosa, ebonakaliswa yintsholongwane ephumayo, ebonakalisa ukufakwa kwimbungu . Ngokuqhelekileyo oku akukwenzekayo nantoni na, okanye kwenzeka, kodwa kungabonakaliyo kumfazi. Ubuhlungu ngexesha lokumiselwa kweqanda le-fetal akufanele liqheleke. Enyanisweni, abanye abesetyhini bathi bavakalelwa ngumzuzu wokumiswa.
Ngokukhawuleza emva kokubambisa iqanda lomntwana, uhla lwalo lwangaphandle luqala ukuvelisa iHCG - okubizwa ngokuba yi-hormone yokukhulelwa. Nguye ozisa umzimba wonke wokuqala kokukhulelwa. Ewe, kwaye iimvavanyo zokukhulelwa zijoliswe ekuqwalaselweni kwe-hormone. Kwaye kubonakala imichilo emihle xa i-hCG ifikelela kwizinga elithile.
Indawo yeqanda le-fetal kwi-uterus
Iqanda lomntwana lingasetyenziselwa kwiindawo ezahlukeneyo zesisu, kuxhomekeka kwiimeko ezithile, kodwa ngokuqhelekileyo kubakho kwindonga yangaphambili okanye yangemva kwesisu. Isiqhotyoshelo esihle kakhulu seqanda lomntwana esezantsi kwesibindi. Ukuba kukho ukutsalwa okuphantsi kweqanda le-fetal, oku kusongela i-placenta previa esikhathini esizayo.
Inyaniso ayiyiyo inyikima ngexesha lokuqala lokukhulelwa, ukuba une-ultrasound ibonisa ukuba iqanda lomntwana lixhomekeke kwisibeletho esiphantsi. Kwi-95% yamatyala enkampu yokukhulelwa i-placenta ihamba, iphakama yonke indlela eya ngasezantsi kwesibeletho.
Kwi-5% ekhoyo yamatyala, kukho onke amathuba okutshintshela ngokupheleleyo ukukhulelwa nokuzala ngaphandle kwengxaki. Kulula nje ukuba uzinciphise ukuzikhandla ngokomzimba, kwaye ngexesha lokuzalwa ugqirha kufuneka alonge ngenyameko imeko yakho - kukho umngcipheko wokuphazamiseka kwangaphambili kweplantshi ngexesha lokukhulelwa , kulandelwa ukuphuma kwegazi kunye ne-hypoxia yomntwana.
Kwaye ukuba unayo i-placenta previa epheleleyo, kuya kufuneka uzalise ngokucwangcisa i-caesarean section, kuba i-placenta iyayinqanda umlomo wesibeleko somntwana kwaye umntwana akakwazi ukuphuma ngokwemvelo. Kodwa kusekuqaleni ukuba ucinge ngako konke oku, vumela zonke izinto ziqhubeke njengesiqhelo.
Kutheni i-egg fetal ingafaki?
Ukuba isinamathiselo yeqanda lomntwana wesibindi esenzelwa isisu asenzeki, ukukhulelwa kuphelile, kwaye kungabi naso ixesha lokunyathela. Ngokuqhelekileyo iqanda le-fetal lihamba kunye nokuya esikhathini, kwaye ekubeni kungabikho ukulibaziseka, le ntokazi ayiboni ukuba unesisu.
Isizathu salo mzekelo sinokusilela kwe-hormonal (ukuphakama okuphezulu okanye okuphantsi kweprogesterone, estrogen, prolactin, i-glucocorticoids njalo njalo).
Kubaluleke kakhulu ukulungelelaniswa kweembilini zombelethi ukuba ufumane iqanda lomntwana. Ukuba ibhinqa ngaphambi kokukhipha isisu, ukutshiza, ukugqoka i-intrauterine device, ayizange ilandele izifo ezithintekayo nezikhuphayo ngexesha, le nto iphula izixhobo ze-receptor ze-endometrium kwaye iyenzeka ngokungafanelanga kuma-hormone.
Ngenxa yoko, i-mucosa ayikulungele ukukhulelwa. Yaye ukuba iqanda le-fetal ngokwayo lingasebenzi ngokwaneleyo, aluboneli inani elifunekayo le-enzymes elibhubhisa i-mucosa ngexesha elifanelekileyo, ngoko liyakwenzeka kwisibeleko (ukukhulelwa kwesibeletho), i-placenta engaqhelekanga, okanye ukungabikho ndawo.
