Anyị nwere ike ikwu na a tozuru okè kasị follicle - na egg, nke kwesịrị sovulirovat. N'ihi ya, ọ na-aghọ doro anya na na niile ndị a follicle guzobere, emecha ovulate, i.e. ekwe omume nke ime.

The guzobere obere follicles amalite na n'ụbọchị ndị mbụ nke ịhụ nsọ okirikiri. Otú ọ dị, ha ibu na-amalite na gormonozavisyaschuyu ogbo nke na-abịa ozugbo ẹkụre luteal adọ. N'otu oge mbelata ego nke estradiol na progesterone, ma ego nke follicle na-akpali akpali hormone (FSH) enwekwu.

Ọ ga-kwuru na-achị follicle na-emetụta ọtụtụ ihe na-ike-eduga n'ọnwụ ya. Otú ọ dị, na nke nne ahụ e mere ka ya nile Filiks na-iji na-echebekwa ndị egg na ifatilaiza ya. Ya mere, na-achị follicle "echebe" epidermal ibu na-akpata na-enwogha ibu na-akpata (TGF).

Mgbe 5-7 ụbọchị mgbe mmalite nke menarche mmalite na-etolite obere follicles. Ha na-akpọ tertiary ma ọ bụ antral. Of nke e nwere nnọọ ọtụtụ - banyere 10 iberibe. Nke a na-adọ na-akpọ n'oge folliculogenesis proliferation ma ọ bụ mmalite nke e guzobere obere antral follicles . Na dayameta nke a nta entities adịghị gafere 5 mm.

Iduzi oge ovulation kasị follicle ga-eru a dayameta nke banyere 20 millimeters (ikekwe ọzọ). Na saịtị nke follicle etolite corpus luteum nwere obere nta karịa ya ụzọ.

Ọ bụrụ na njikọta spam adịghị ime, mgbe ahụ, a izu mgbe ntọhapụ nke egg si ovary corpus luteum amalite ibelata na size - regresses. Site na oge nke eriri akpa nwa endothelial ịjụ ndị corpus luteum, dị ka a na-achị,-anwụ anwụ, na n'ọnọdu-ya bụ naanị fọdụrụ òkè nke gbajiri echogenicity.

Ekwu okwu nke folliculogenesis, nwere ike adịghị eche echiche nke "persistent follicle."

Persistent akpọ follicle, nke na-aga niile nkebi nke folliculogenesis, ma e wezụga n'ihi na ozugbo ovulation. Olee ihe nwere ike ime ka a onu na-ghọtara. Otú ọ dị, ndị dọkịta na-iri eyịre ka a variant nke norm, n'ezie, ọ bụrụ na ọ na-adịghị mgbe niile ugboro ugboro.
