Ukuthuthukiswa nokulondolozwa kokukhulelwa kungenzeka ngenxa yokusebenza okujwayelekile komzimba ophuzi - isikhumba sesikhashana sokuvimba kwangaphakathi, okuyinto ngaphambi kweviki lama-20 okhiqiza okuthiwa i-hormone-progesterone okuthiwa ukukhulelwa. Ngemuva kwalesi sikhathi, le nhlangano ibelwe i-placenta.
Isenzo se-progesterone siboniswa ekuqinisekiseni ukwanda okwanele koqweqwe olusebenzayo lwe-endometrium, okuvumela emva kokukhulelwa kweqanda ukwenza "ukufika" okulungile kweqanda lomntwana wesisu emgodini we-uterine (implantation). Uma ukhulelwe kwenzeka, umsebenzi we-hormone ukuvimbela "ukulahlwa" kombungu ngokulawula iziphazamiso ezibangelwa uterine ukuze uvikele ukuqala kokuya esikhathini. Ngaphezu kwalokho, kuvimbela ukuvuthwa okusha. Ukuze uqonde ukuthi umzimba ophuzi uphulukisa kanjani umsebenzi wakhe wokudala ibhalansi ye-hormone ngesikhathi ukhulelwe, ubukhulu be-gland "ephuzi" bufundwa.
Inani lamahomoni okhiqiza umzimba ophuzi, linquma ubukhulu balo. Ngesikhathi esifanayo, izinguquko ezitholakala emgodini we-hormonal ziholela ekutheni ngezikhathi ezahlukene zokukhulelwa azihlali njalo: ezinkathini zokuqala, umzimba ophuzi ukhula kuqala, futhi ngokuhamba kwesikhathi - emasontweni angu-16-20 okukhulelwa - kuba mncane futhi kancane kancane alahleke, anike amandla amandla e-placenta, njengoba kwakunjalo okukhulunywe ngenhla.
Usayizi ojwayelekile womzimba ophuzi
Umkhuba womzimba ophuzi ngesikhathi ukhulelwe ungama-10-30 mm ububanzi. Ukwehluka kokubanzi noma okuncane okuvela kulolu hlu lwamanani kubonisa izimo ezinjengokungasebenzi noma i-cyst yomzimba ophuzi, odinga ukubuyiselwa nokujwayelekile kwezinga le-progesterone emzimbeni wesifazane. Ngakho-ke, isibonelo, ukungahambi kahle komzimba noma ukungaqiniseki kwamaprotheni ekwenzeni i-fetus kungaholela ekungathathwa ngesikhathi sokuqeda ukutholakala kokuntuleka komzimba ophuzi. Ukungaqiniseki kwe-progesterone, ebonakala ngomzimba omncane ophuzi (kufika ku-10 mm ububanzi), ungase wenziwe nge-progesterone equkethe amalungiselelo (i-Dufaston, i-Utrozhestan).
I-cyst yomzimba ophuzi ngesikhathi sokukhulelwa isakhiwo esiyingozi, ubukhulu bayo obubanzi obungaba ngu-6 cm. Akusiyo isongo esithile, ngoba, naphezu kobukhulu bayo, umzimba ophuzi uqhubeka ukhiqiza i-progesterone. Isimo se-cystic singaba nesimiso noma sibe nezinhlungu zokudonsa kancane esiswini esingaphansi. Ngokuvamile, i-cyst kufanele ichitheke yedwa, kodwa noma kunjalo, ukuze igweme izinkinga ezingenzeka (ukuphuma kwegazi, ukudakwa komzimba), ukuqapha okudingekayo kwesimo sayo kuyadingeka. Ngakho-ke, phakathi nokushintsha kwemisebenzi e-placenta, umzimba ophuzi udinga ukuhlolwa okudingekayo kwe-ultrasound.
