Into eyinhloko yama-ovari kumfazi yi-follicles, equkethe iqanda. Emaceleni kukhona izingqimba ezimbili ze-epithelial kanye nezingqimba ezimbili zegobolondo elixhunyiwe.
I-Follicles kuma-ovari - evamile
I-reserve follicular yama-ovaries wesifazane isethwe ngesikhathi sokuzalwa, kulo mzuzu kunezinkulungwane ezingaba ngu-400 kuya ku-2 million. Ngaphambi kokukhulelwa kuma-ovari kukhona ama-follicle amakhulu, ubukhulu bawo - kufika ku-microns angu-200, aqukethe ama-oocyte we-oda elingu-1, ukuthuthukiswa okumile ku-1 prophase meiosis.
Kusukela ekuzalweni kwentombazane kuya eminyakeni yobudala, ukuvuthwa kwe-follicles akukwenzeka, futhi kuphela lapho ukuthuthukiswa ngokocansi kuqala ukukhula kwe-follicles, futhi ngaphandle kwayo kuphuma ama-ovules wokuqala. Inombolo ye-follicles ema-ovarie yentombazane ngayinye ihlukile, kodwa ngokwesilinganiso umkhuba wabo ekuqaleni kokukhulelwa kungaba ngu-300 000.
I-apparatus yezintambo zama-ovari: i-follicles
I-follicle ngayinye ye-ovarian ngaphambi kokukhululwa kweqanda, idlula ngezigaba ezilandelayo zentuthuko:
- I-follicle eyinhloko equkethe iqanda elivuthiwe epithelium ye-follicular, okuzungeze lapho kunezigobolondo ezivela kumathiski ahlangene. Umjikelezo ngamunye wokuya esikhathini uqala ukukhula follicles ngaphezulu (kusuka ku-3 kuya ku-30), lapho ama-ovari enza khona ama-follicles e-preantral.
- Izintambo eziphambili (preantral) zikhula, i-oocyte yazo ihaqwe ngendwangu, futhi emangqamuzaneni e-epithelium follicular, i-estrogens iqala ukuhlanganiswa.
- I-secondary (antral) follicles iqala ukukhiqizwa kwe-flulicular fluid engxenyeni ye-intercellular equkethe i-estrogens ne-androgens.
- I-tertiary (preovulatory) follicles: kusukela enombolweni enkulu ye-follicles yesibili, eyodwa iba yilapho ikhulu, inani le-follicular fluid kuyo landa izikhathi eziyi-100 phakathi nesikhathi sokuthuthukiswa, kanti ubukhulu bama-micrometer angamakhulu amaningana bukhula buya ku-20 mm. Iqanda libhekene ne-tubercle ethwala amaqanda, futhi emzimbeni we-follicle, izinga le-estrogens landa, ama-follicle asele asele asele ngaphezulu.
I-Ultrasound ye-follicles ngesikhathi sokuthuthukiswa kwayo
Ukunquma ukukhula kwe-follicle e-ovari ngesikhathi sokuya esikhathini, i-ultrasound yenziwa ngezinsuku ezithile. Kuze kube usuku lwesishiyagalombili lomjikelezo, izintambo ezincane azitholakali, kodwa ngosuku lwama-7 no-9 ukukhula kwama-follicle wesibili emaqanda amaqanda aqala. Lezi izintambo ezincane nobukhulu bazo zingafinyelela ku-4-8 mm. Ama-follicles amaningi kuma-ovarie amancane phakathi nalesi sikhathi angase akhombise ukucindezeleka kwe-ovari, ukusetshenziswa kwezizalo zokuvimbela, nokuphulwa kwesizinda semvelo emzimbeni (ukwehla ezingeni lika-LH).
Ngokuvamile, ngosuku lwesishiyagalolunye nesishiyagalolunye nesishiyagalolunye nesishiyagalolunye ovary kukhona ambalwa follicles ukukhula, kanti esikhathini esizayo, follicle eyodwa kuphela ovary kwelinye ovary uyaqhubeka sikhule, nakuba ekuqaleni kokuvuthwa i-ovary yesibili iqukethe follicles secondary. I-follicle ephezulu e-ultrasound ibukeka njengeyindilinga yokwenza ama-anhegenous kuze kube ngu-20 mm ngobukhulu. Ukungabi khona kwama-follicle okuvelele emaqanda ama-ovari kumjikelezo amaningana kungase kube uphawu lokungabikho kwabesifazane.
Izimbangela zokukhula okungavamile kwe-follicle, ukuxilongwa nokuphathwa kwezifo
Ama-follicle emaqanda ama-ovari angeke akhule nhlobo, angaqhubeki kuze kube ngosayizi ofanele, ukuvota kungase kungenzeki, futhi ngenxa yalokho,
Ukunquma imbangela yezinto ezingavamile ekuthuthukiseni izintambo, akuyona nje i-ultrasound eyabelwe, kodwa futhi nokuzimisela izinga lama-hormone ocansi ewesifazane. Kuye ngezinga lama-hormone egazini ngezigaba ezihlukahlukene zomjikelezo, umjozi wezinkinga wegazi ubeka izidakamizwa ezicindezelayo noma ezivuselela i-tez noma amanye ama-hormone, ukwelashwa ngama-hormone ocansi, futhi, uma kunesidingo, ukwelashwa kokuhlinzwa.
