Kuvandudza uye kuchengetedza pamuviri kunokwanisika pamusana pekushanda kwechimiro chemuviri - chirwere chenguva pfupi chekuvhara mukati, iyo isati yasvika vhiki ye20 inobudisa izvo zvinonzi inonzi hormone-progesterone. Mushure mekunge nguva iyi, basa iri rakapiwa kune placenta.
Chiito cheprogesterone chinoratidzwa mukugadzirisa kukura zvakakwana kwehutano hwemagetsi e endometrium, zvichiita mushure mokunge mazai ei aite "kukwirira" kwakarurama kwema fetal egg mu uterine cavity (implantation). Apo mimba inobata, basa rehomoni nderokudzivirira "kurambwa" kwembryo nokudzivirira zvipembenene zvehutachiona zvehutano kuitira kuti zvidzivirire kutanga kwekuenda kumwedzi. Mukuwedzera, inodzivirira hutachiva hutsva. Kuti unzwisise kukosha kwemuviri wechirwere kunoporesa nebasa rayo yekusika hutachiona hwemashure panguva yekuzvitakura, ukuru hwe "yellow" gland inodzidzwa.
Nhamba yehomoni inobereka yomuviri, inotarisa kukosha kwayo. Panguva imwecheteyo, kuchinja kwehutachiona hunokonzera kuti panguva dzakasiyana-siyana dzepamuviri havasi kugara: mumatangiro ekutanga, mutumbi wejena unokura pakutanga, uye gare gare - pamasvondo makumi matanhatu nemakumi matanhatu kubva pakuberekwa - kunowira zvishoma uye zvishoma nezvishoma kunopera, kugovera masimba kune placenta, sezvazvaive zvakataurwa pamusoro apa.
Izvo zvakasikwa kukura kwejecha muviri
Chimiro chejena muviri panguva yekuzvitakura chiri 10-30 mm muhupamhi. Kukanganisa kwakakura kana kuti kuderera kubva kune huwandu hwehutano hunoita zvinhu zvakadai sekusakwanira kana cyst yemazuva, iyo inoda kudzorerwa nekusimudzira kwezinga reprogesterone mumuviri wemukadzi. Saka, somuenzaniso, kupererwa kwepamuviri kana kushaya kukwana mumutambo wekutakura fetus kunogona kutungamirira kuti isatorwa munguva inopedza kubvisa kuongororwa kwekushayikwa kwomuviri. Progesterone isingakwanisi, inozivikanwa nekatsvuku muviri (kusvika kusvika 10 mm muhupamhi), inogona kubhadharwa nekushandiswa kweprogesterone ine magadzirira (Dufaston, Utrozhestan).
Iyo cyst body inobata pamuviri inobata muviri, iyo yakareba iyo yakareba inogona kusvika kusvika masendimita matanhatu.Iyo haisi mungozi, sezvo, pasinei nehukuru hwayo, mutsvuku unoramba uchibudisa progesterone. Chimiro chinogona kunge chisingaiti kana kuti nekurwadza zvishoma mumimba pasi. Kazhinji, kristi inofanira kuparara pachayo, asi zvisinei, kuitira kuti usapinda zvinetso zvinokonzera (kubuda ropa, kudhakwa kwemuviri), zvinotarisirwa kuongororwa zvemuitiro wacho zvinodiwa. Nokudaro, panguva yekuchinja kwemaitiro kune placenta, iyo yemajemi muviri inoda kushandiswa kwechirongwa che ultrasound.
