Follicles pamashizha

Chinhu chinokosha chemavha mavari mumukadzi ndeye follicles, ine egg. Pasi payo pane epithelial zvidimbu uye zvidimbu zviviri zvekubatanidza shell.

Nyaya dzinowanikwa pamapapiro omukati - inowanzo

Izvozvo zvinokonzerwa nemapapiro emukadzi zvinowanikwa pakuberekwa, panguva ino pane mazana anenge mazana mana uye kusvika kumamiriyoni maviri. Usati uchangopera mumayamu mavari masikati makuru, masero awo - kusvika pamamita mazana maviri emakironi, ane maoocyte emurairo 1, kukurudzirwa kwakamira muna 1 prophase meiosis.

Kubva pakaberekwa musikana kusvika kumakore ekuyaruka, kushambidzwa kwema follicles hazviitiki, uye chete panguva yekukurudzirana kwepabonde kunotanga kukura kwe follicles, uye kunze kwadzo kunobuda mavhiri ekutanga. Nhamba ye follicles mu mavharasi emusikana mumwe nomumwe akasiyana, asi paavhareji tsika yavo pakutanga kwekuyaruka inenge 300 000.

Zvinyorwa zvipfeko zveivhai: follicles

Nhengo imwe neimwe ye-ovarian follicle isati yasunungurwa evha, inopfuura nepakati pezvikamu zvinotevera zvekugadzirwa:

1. Chirwere chepakutanga chine mazai echinyorwa mu follicular epithelium, kwakapoteredza maiva nehombodo kubva mumagetsi anogadzirisa. Mwedzi mumwe nomumwe unotanga kukura kupfuura follicles (kubva pa3 kusvika ku30), iyo mavha mavari anogadzira preantral follicles.
2. Primary (preantral) follicles inokura, maoocyte avo akakomberedzwa nembambo, uye mumasero e follicular epithelium, estrogens inotanga kuumbwa.
3. Secondary (antral) follicles inotanga kubudiswa kwe follicular fluid mu intercellular nzvimbo ine estrogens uye androgens.
4. Zvidzidzo zvepamusoro (preovulatory) follicles: kubva pachiwande chikuru chechipiri follicles, imwe inowedzera, chiyero che follicular fluid mauri inowedzera kazana munguva yekukura, uye ukuru hwemazana mazana emakrometer inokura kusvika 20 mm. Evha iri pane mazai anotakura mazai, uye mumvura ye follicle, uwandu hweedrogen huwandu, zvisizvo zvechipiri follicles zvinopfuura.

Ultrasound ye follicles panguva yavo yekukura

Kuti uone kukura kwehupenzi muyvary panguva yekuenda kumwedzi, ultrasound inoitwa pane imwe mazuva. Kusvikira zuva rechinomwe rekufamba-famba, follicles hazvisati dzagadziriswa, asi musi we7 kusvika ku9 kukura kwechipiri follicles mu mavha mavhiri anotanga. Aya madiki mapundu uye hukuru hwavo hunogona kusvika kusvika 4-8 mm. Mhando dzakawanda dzemapundu mazhizha panguva iyi dzinogona kuratidza mavari ekunyengedza, kushandiswa kwemishonga, nekuputsa kwemarimoni mumutumbi (kuderera mumwero weLH).

Kazhinji, pazuva rechinomwe 7-9 muhutari kune mashoma mashoma, uye mune ramangwana, rimwe chete rinonyanya kukosha mune imwe chirwere chinoramba richikura, kunyange zvazvo pakutanga kwekutsvaga kwehutachiwana wechipiri chevhiri rinowedzerawo follicles. Iyo inonyanya kuve yakagadziriswa inonzi ultrasound inoratidzika seyenderedzwa yakagadzirwa maitiro kusvika 20 mm muhukuru. Kushayikwa kwema follicles muhutachiona hutachiona hungave chiratidzo chekushaya vana muvakadzi.

Zvimwe zvinokonzera kusakanganiswa kwemapurisa, kukurapa uye kurapwa kwematambudziko

Nyuchi dzinenge dzisingadi kukura zvachose, usati dzakura kusvika kuhukuru hwakakodzera, ovulation haigone kuitika, uye semugumisiro, mumwe mukadzi anotambura nekushaya vana. Asi zvinokwanisika uye kumwe kuputsa kwekutsvaga kwema follicles - polycystic ovary . Nayo, ultrasound haigoni kuonekwa neyakasikwa, asi nekuwedzera kwenhamba yezvipembenene mumakumbo maviri-mavari-anopfuura 10 muhukuru hwega kubva 2 kusvika 10 mm, uye mugumisiro uchavawo kusagadzikana.

Kuti uone chinokonzera kusakanganisika mukugadzirwa kwemapurisa, kwete ultrasound chete inorayirwa, asiwo kusarudza kwehutachiona hwemadzimai evanhukadzi. Zvichienderana nehuwandu hwemhomoni muropa mune zvikamu zvakasiyana-siyana zvekufamba-famba, gynecologist inorondedzera zvinodhaka zvinodzvinyirira kana kukurudzira kufanana kwetz kana mamwe mahomoni, kurapwa nemahomoni ezvepabonde, uye, kana zvichidikanwa, kurapwa kwekuvhiya.
