Okuqukethwe
Iyini i-corpus luteum?
I-corpus luteum, ebizwa nangokuthi "i-corpus luteum", ikhula okwesikhashana inyanga ngayinye phakathi nengxenye yesibili yomzimba. umjikelezo wokuya esikhathini, futhi ngokunembe kakhudlwana kwesigaba seluteal, okungukuthi ngemva nje kokuphuma kweqanda.
Eqinisweni, uma i-ovulation isiphelile, i-ovarian follicle equkethe i-oocyte iyashintsha futhi ithatha umbala ophuzi ukuze ibe indlala ye-endocrine etholakala ngaphakathi kwe-ovary futhi indima yayo eyinhloko iwukukhipha. progesterone.
Ukubaluleka kwe-corpus luteum ukuze ukhulelwe
Edingekayo ekuzaleni nasekukhuleni okufanele kokukhulelwa, i-progesterone ekhiqizwa yi-corpus luteum isiza ukulungisa i-endometrium ukuze yamukele iqanda ngemva kokuhlangana. Ulwelwesi lwesibeletho - noma i-endometrium -, izacile kakhulu ekuqaleni komjikelezo wokuya esikhathini, luzoqina ngokubukeka kwemithambo yegazi namaseli ukuze kunikeze indawo ekahle yesiguli. ukufakelwa, okungukuthi, isikhathi lapho umbungu ufaka khona esibelethweni.
Kulinganiselwa ukuthi i-progesterone ikhishwa ezinsukwini ezingu-14 zokugcina zomjikelezo wokuya esikhathini. Imfihlo eyenza ukwanda kwezinga lokushisa lomzimba - ngaphezu kwama-37 ° C -, isibonakaliso sokuthi i-ovulation yenzekile.
Indima ye-corpus luteum ngesikhathi sokukhulelwa
Ngemva kokukhulelwa, i-embryo iyazigxilisa ngemva kwezinsuku ezimbalwa kuphela esibelethweni futhi ikhiphei-hormone HCG - ihomoni ye-chorionic gonadotropin - noma i-beta-hCG, nge-trophoblast ezoba i-placenta. Kuyinkomba yokukhulelwa izinga layo likhuphuka phakathi namasonto okuqala ngemva kokukhulelwa. Imvamisa kungalesi sikhathi lapho kuvela khona izimpawu zokuqala zokukhulelwa: ukukhathala, isicanucanu, imizwa, ukuvuvukala kwesifuba ...
Indima yehomoni i-HCG iwukuqinisekisa ukusebenza kahle kwe-corpus luteum kanye nokukhishwa kwe-progesterone, okubalulekile ekugcineni ukufakwa kombungu esibelethweni. Ezinyangeni ezintathu zokuqala, i-corpus luteum izoqhubeka nokukhiqiza le hormone ebalulekile yokukhulelwa. Kusukela enyangeni yesine, i-placenta ivuthwe ngokwanele ukuze kuqinisekiswe ukushintshana phakathi kukamama nengane iyodwa.
Kuyini ukuxhumana phakathi kokuphuphuma kwesisu kanye ne-corpus luteum?
Ezimweni ezingavamile, i- ukukhulelwa kwesisu kungase kuhlotshaniswe nokuntuleka kwe-corpus luteum, ebizwa nangokuthi ukungasebenzi kahle kwe-luteal. Ukushoda kweHormonal okungase futhi kuhlanganiswe nobunzima bokukhulelwa.
Ukwelashwa kwezidakamizwa kungase kunqunywe ukunxephezela ukwehluleka.
I-Cyclic corpus luteum: lapho ukuvundiswa kungenzeki
Uma iqanda lingavundisiwe, libizwa ngokuthi i-cyclic corpus luteum. Izinga lokuphuma kwamahomoni liyancipha kakhulu, isibeletho nemithambo yegazi olwelwesi lwesibeletho kuyafingqa. Ingxenye engaphezulu ye-mucosa bese ixoshwa ngendlela yemithetho. Kuyisiqalo somjikelezo omusha wokuya esikhathini.
