Ukutshalwa kweqanda le-fetal kulandelwa ukuphuma kweqanda lomntwana kanye nohambo lwawo olude ngokusebenzisa i-tube uterine ukuya emgodini we-uterine. Le nqubo ithatha cishe izinsuku ezintathu. Enye iqanda lihamba eduze kwesibeletho ngokufuna indawo yokumiswa. Futhi ngosuku lwesikhombisa kuphela emva kokuba umanyolo we-blastocyst uqala isingeniso emgqeni we-epithelium wesibeletho.
Futhi inqubo yokwethulwa kweqanda lesibusiso emgqeni wesibeletho kuthiwa ukufakelwa. Kodwa ungacabangi ukuthi lokhu kwenzeka ngokushesha. Isikhathi sokunamathiswa kweqanda lesibusiso cishe amahora angu-40.
Ngezinye izikhathi kunomonakalo omncane ku-mucosa, okuboniswa ukuphuma okuncane, okuwuphawu lokufakelwa kombungu . Ngokuvamile lokhu akukwenzeka nhlobo, noma kwenzeke, kodwa kungabonakali kowesifazane. Ubuhlungu ngenkathi kusetshenzwa iqanda lomntwana wesisu akufanele kube yinto evamile. Yiqiniso, abanye besifazane bathi banomuzwa wokumiswa.
Cishe ngokushesha ngemuva kokufaka iqanda le-fetal, ungqimba lwangaphandle luqala ukukhiqiza i-hCG - okuthiwa i-hormone yokukhulelwa. Nguye ozisa wonke umzimba wokuqala kokukhulelwa. Yebo, nokuhlolwa kokukhulelwa kugxile ekwamukeleni ukuhlushwa kwe-hormone. Futhi amaqoqo amabili ahlonishwayo avela lapho ukuhlushwa kwe-hCG kufinyelela ezingeni elithile.
Indawo yeqanda lesisu lokubeletha esibelethweni
Iqanda lomntwana lingasetshenziswa ezindaweni ezihlukene zesibindi, kuye ngezimo ezithile, kodwa ngokuvamile kuvame ukuvela odongeni lwangaphakathi noma oluse ngemuva kwesibindi. Ukunamathiselwe okuvelele kakhulu kweqanda le-fetal ngaphansi kwesibeletho. Uma kukhona ukugxila okuncane kweqanda le-fetal, lokhu kusongela i-placenta previa esikhathini esizayo.
Iqiniso akuyona ukwethuka phakathi nezinyathelo zakuqala zokukhulelwa, uma une-ultrasound yembule ukuthi iqanda lokubeletha linamathele esibelethweni esiphansi. Ezimweni ezingu-95% zenkathi yokukhulelwa i-placenta ihamba, ikhuphuka yonke indlela eya esibelethweni.
Ku-5% amacala asele, kunamathuba onke okudlulisela ngokuphelele ukukhulelwa futhi abelethe ngaphandle kwezinkinga. Kulula ukuthi udinga ukuzikhandla ekuzikhandla ngokomzimba, futhi ngesikhathi sokuzalwa udokotela kufanele aqaphele ngokucophelela isimo sakho - kunengozi yokuphazamiseka kokuqala kokugcoba ngesikhathi sokukhulelwa , kulandelwa ukuphuma kwegazi kanye ne-hypoxia yengane.
Futhi uma usenayo i-previa ephelele, kuzodingeka ubelethe ngesigaba sokudla, ngoba i-placenta igwema ngokuphelele umlomo wesibeletho somlomo wesibeletho futhi umntwana akakwazi ukuphuma ngokwemvelo. Kodwa kusenesikhathi kakhulu ukucabanga ngakho konke lokhu, vumela konke kuqhubeke njengokujwayelekile.
Kungani i-egg fetal ingathinti?
Uma ukunamathiselwa kweqanda lokubeletha esibelethweni kungeke kwenzeke, ukukhulelwa kuphela, futhi kungabi nesikhathi sokuqhubeka. Ngokuvamile iqanda le-fetal lihambisana nokuya esikhathini, futhi njengoba kungabikho ukubambezeleka, owesifazane akaqapheli ukuthi unesisu.
Isizathu salesi senzakalo singaba ukwehluleka kwe-hormonal (ukuphakama okuphezulu noma okuncane kwe-progesterone, estrogen, prolactin, glucocorticoids njalonjalo).
Okubaluleke kakhulu ukulungiswa kwekhanda elimangalisa lesibeletho sokuthola iqanda lomntwana. Uma owesifazane ngaphambi kokukhipha isisu, ukugqoka, egqoke i-intrauterine device, uye wangaphazamisa izifo ezithathelwanayo nezivuvukalayo ngokuhamba kwesikhathi, lokhu kuphula ama-receptor apparatus we-endometrium futhi iphendula ngokungalungile kuma-hormone.
Ngenxa yalokho, i-mucosa ayikulungele ukukhulelwa. Futhi uma iqanda le-fetal ngokwayo lingasebenzi ngokwanele, alihlinzeki inani elidingekile le-enzyme elibhubhisa i-mucosa ngesikhathi esifanele, khona-ke kungenzeka ku-cervix (ukukhulelwa komlomo wesibeletho), i-placenta engavamile, noma ukungena ndawo.
