Lub ntsiab mechanism yog nws transformation thiab cov transformation ntawm lub follicle rau hauv ib tug paub tab qe.

Lub ntsiab theem ntawm folliculogenesis yog lub tsim ntawm lub hom (thawj) follicle.

Hom hauv paus tsim los ntawm successively tswv yim theem:

- pib ntawm tsim ntawm ib tug tibneeg ntau ntau cov me me antral hauv paus ,

- txoj kev loj hlob thiab kev loj hlob ntawm me me hauv paus

- maturation ntawm lub hom follicle,

Peb yuav hais tias ib tug paub tab tseem ceeb follicle - lub qe, uas yuav tsum tau sovulirovat. Yog li, nws yuav paub tseeb hais tias tag nrho cov kauj ruam follicle tsim, nws thiaj li ovulate, i.e. tau ntawm cev xeeb tub.

Cov tsim ntawm me me hauv paus pib nrog cov thawj hnub ntawm lub cev ntas. Txawm li cas los, lawv txoj kev loj hlob yog pib xwb gormonozavisyaschuyu theem uas los sai li sai tau tom qab kawm tiav ntawm lub luteal theem. Nyob rau tib lub sij hawm txo tus nqi ntawm cov estradiol thiab progesterone, tab sis tus nqi ntawm cov follicle stimulating lawm (FSH) tsub kom.

Nws yuav tsum tau muab sau tseg tias tus tseem ceeb follicle yog cuam tshuam los ntawm ntau yam tseem ceeb uas yuav ua rau nws txoj kev tuag. Txawm li cas los, tus poj niam lub cev yog tsim kom tag nrho cov ntawm nws cov dab raug tswj khaws cia lub qe thiab fertilize nws. Yog li ntawd, cov hom follicle "tiv thaiv" epidermal kev loj hlob tau thiab hloov tau lub kev loj hlob tau (TGF).

Tom qab 5-7 hnub tom qab qhov pib ntawm menarche pib tsim me me hauv paus. Lawv kuj hu ua tertiary los yog antral. Ntawm uas muaj heev ib tug xov tooj - txog 10 daim. Qhov no theem no yog hu ua thaum ntxov folliculogenesis loj hlob los yog thaum pib ntawm lub tsim me me antral hauv paus . Cov kab uas hla ntawm cov me chaw tsis pub tshaj 5 hli. Lawv nyob rau hauv ib lub "hlaws" nyob rau periphery ntawm lub zes qe menyuam. Rau ib txhia lub sij hawm, ib feem ntawm lub follicle qab nyob rau hauv loj thiab yog muaj zog.

Li ntawd, cov hom follicle yog tsim tom qab kwv yees li 10 hnub ntawm lub cev ntas, thiab lub sij hawm no nws ntev mus txog 15 millimeters. Lwm tus yog hauv paus uas tau ua tsis tau tejyam mus nce lub Desired qhov ceeb thawj, regress thiab tuag. Raws li ib tug tshwm sim, peb yuav xaus tias tus tseem ceeb follicle yuav ua tau ntau tshaj ib tug. Thaum ob tug los yog ntau tshaj mature qe uas yog ces fertilized, tsim ntau yam uas cev xeeb tub. Qhov no tus txheej txheem yog tsis ntau, tab sis xws li mob sau cia. Feem ntau cov feem ntau nws yog iatrogenic ua tshuaj raws li nyob rau hauv cov tshuaj hormones, qhov ncauj contraceptives los yog IVF.

Yuav kom ncaj lub sij hawm ntawm ovulation hom follicle yuav tsum mus txog ib lub cheeb ntawm txog 20 millimeters (tej zaum ntau). Ntawm qhov chaw ntawm lub follicle rau corpus luteum muaj ib tug me ntsis me me dua nws cov thawj ntawm.

Yog hais tias fertilization tsis tshwm sim, ces ib lub lim tiam tom qab qhov kev tso tawm ntawm lub qe los ntawm lub zes qe menyuam corpus luteum pib kom txo tau nyob rau hauv loj - regresses. By lub sij hawm ntawm uterine endothelial rejection ntawm lub corpus luteum, raws li ib tug txoj cai, tuag, thiab nyob rau hauv nws qhov chaw no xwb seem ntawm lub siab tawg tag echogenicity.

Hais txog folliculogenesis, yuav tsis nyob rau lub tswvyim ntawm "pheej follicle."

Pheej nws hu ua tus follicle, uas kis tau rau tag nrho cov ua sawv ntawm lub folliculogenesis, tsuas yog tam sim ntawd ovulation. Yuav ua li cas yog vim li cas yuav ua tau kom qhov no tshwm sim yog tsis qoos taub. Txawm li cas los, cov kws kho mob feem ntau noj persistence raws li ib tug variant ntawm lub cai, ntawm chav kawm, yog hais tias nws yog tsis lossi rov qab.

Tej zaum nws tshwm sim hais tias ib tug pheej follicle yog hloov dua siab tshiab rau hauv ib tug me me ntawm zes qe menyuam cyst. Ntawm tus neeg mob nyob rau hauv uas muaj yog ib tug cyst, koj yuav tsum tau saib. Yog hais tias tus txheej txheem no tsis ua kev tsis txaus siab, cov kev kho mob yog tsis yuav tsum tau.

Raws li txoj cai, pheej follicle ruptures ntawm ovulation, tab sis cev xeeb tub nrog rau qhov no qhov teeb meem yog suab tsis yooj yim sua vim hais tias ntawm lub tsev me nyuam ib yam nkaus thiab nyias endometrium rau implantation.
