Chinthu chachikulu pa mazira ambiri mwa mkazi ndi follicles, omwe ali ndi dzira. Pansi pake pali zigawo ziwiri zosiyana siyana ndi zigawo ziwiri za chipolopolo chogwirizanitsa.
Mapuloteni pa mazira ochuluka - nthawi zambiri
Malo osungirako mapiritsi a amayi amatha kubereka, panthawiyi pali pafupifupi 400,000 mpaka 2 miliyoni. Asanafike msinkhu m'mimba mwa mavalasi ndi ma follicles oyambirira, kukula kwake - mpaka ma microns 200, ali ndi ma oocyte a 1 dongosolo, chitukuko chimene chinaima mu 1 prophase meiosis.
Kuchokera pa kubadwa kwa msungwana mpaka msinkhu wa zaka zachinyamata, kusasitsa kwa follicles sikuchitika, ndipo pokhapokha pa chitukuko cha kugonana kumayamba kukula kwa follicles, ndipo kuchokera mwa iwo mumachokera mazira oyambirira. Chiwerengero cha ma follicles m'mayamayi a mtsikana aliyense ndi osiyana, koma pafupipafupi chizoloŵezi chawo pachiyambi cha kutha msinkhu ndi pafupi zikwi mazana atatu.
Zipangizo zamatsenga za mazira ochuluka: follicles
Nthendayi iliyonse yamatenda asanatulutse dzira, imadutsa muzigawo izi:
- Mapuloteni aakulu omwe ali ndi dzira lachangu mu follicular epithelium, kumene kuli zipolopolo zochokera m'magulu ogwirizana. Mwezi uliwonse umayamba kukulirakulira (kuyambira 3 mpaka 30), yomwe mazira amawonekedwe amapanga mapuloteni oyambirira.
- Mapuloteni oyambirira (preantral) amakula, ma oocyte amazungulira ndi nembanemba, ndipo m'maselo a follicular epithelium, estrogens amayamba kupanga.
- Mapulogalamu apakati (antral) amapanga kupanga follicular fluid m'kati mwa malo okhala ndi estrogens ndi androgens.
- Mapulogalamu apamwamba (preovulatory) follicles: kuchokera kumtundu wambiri wa follicles, umodzi umakhala waukulu, kuchuluka kwa follicular madzi m'thupi kumawonjezereka kasanu pa nthawi ya chitukuko, ndipo kukula kwa micrometer mazana ambiri kumakula kufika 20 mm. Dzira lili pa dzira lodzaza dzira, ndipo mumadzimadzi amtunduwu, mlingo wa estrogens umakhala wopindulitsa, ndipo mapuloteni otsalawo amakhala opitirira.
Ultrasound ya follicles pa chitukuko chawo
Kuti mudziwe kukula kwa follicle mu ovary pa nthawi ya kusamba, ultrasound ikuchitika masiku ena. Mpaka tsiku lachisanu ndi chiwiri la zozungulira, mapuloteni sakhala otsimikiziridwa, koma pa tsiku la 7 mpaka 9 kukula kwa ma follicles yachiwiri mu mazira oyamba amayamba. Izi ndizigawo zing'onozing'ono komanso kukula kwake zimatha kufika mpaka 4-8 mm. Ma follicles ambiri pa mazira ang'onoang'ono panthawiyi angasonyeze kuti ovarian, kutengera njira zowathandiza kulera, komanso kuphwanya mahomoni m'thupi (kuchepa kwa mlingo wa LH).
Kawirikawiri, pa tsiku la 7 mpaka 9 mu ovary muli zochepa zosawerengeka, ndipo m'tsogolomu, chipolopolo chimodzi chokha chomwe chimayamba kukula, ngakhale kuti kumayambiriro kwa kusamba, kachilombo kachiwiri kamakhala ndi follicles yachiwiri. Chipangizo chachikulu cha ultrasound chimawoneka ngati chozungulira chomwe chimapangidwa mpaka 20 mm kukula. Kupezeka kwa ma follicles opambana mu mazira ochulukirapo angakhale chizindikiro cha kusabereka kwa amayi.
Zomwe zimayambitsa chithunzithunzi chopanda pake, matenda ndi matenda
Mapuloteni omwe amapezeka m'mimba mwake sangawonjezere konse, sangafike kukula, kukula kwa ovulation sikutheka, ndipo chifukwa chake,
Kuti mudziwe chomwe chimayambitsa vuto la kupangika kwa ma follicles, sikuti ultrasound imayikidwa, koma komanso kutsimikiza kwa msinkhu wa mahomoni ogonana mwa amayi. Malinga ndi msinkhu wa mahomoni m'magazi osiyana siyana, mzimayi amaletsa mankhwala omwe amachititsa kuti mankhwalawa asakanikizidwe, kapena kuti amachititsa kuti mankhwalawa asakanike.
