Iyo yakave ichizivikanwa kwenguva refu kuti panguva yekuzvitakura mumuviri wemai mune ramangwana, kuchinja kukuru kwehomoni kunowanzoitika, pasina iyo iyo kubudirira kwayo uye mugumisiro hazvibviri. Zvisinei, havasi mukadzi wese anoratidzwa kuti aongorore huwandu hwemhomoni. Kuongororwa kweropa kune mahomoni panguva yekuzvitakura kunogadzirirwa zviratidzo zvakananga: kunowanzoparara, kusabereka, in vitro fertilization, kushungurudzwa kwe ectopic pamuviri. Icho chinonyanya kushandiswa chekushandiswa kweHommonal kuve nekudzivirira pamuviri , iyo inogona kuitwa pamba (zvichienderana nenotsanangudzo yepamusoro ye chorionic gonadotropin murwizi). Ichi chinyorwa chichakurukura zvinhu zvekuchinja mumwero wehomoni panguva yekudzivirira.
Maitiro ehomoni panguva yekudzivirira
Kuchinja kunonyanya kukosha kunowanikwa kune mahomoni evanhukadzi. Mune pamuviri, chirwere chepituitary chinowedzera kaviri uye kusunungurwa kwekusunungura mahomoni kunoguma, izvo zvinokurudzira kusunungurwa kwehomoni dzepabonde. Nhamba ye follicle inokurudzira uye inotenderera mahomoni panguva yekuzvitakura inoderedzwa zvikuru, iyo inobatsira kudzivisa kusimwa kwe follicles mune mavha mavari uye kunodzivirira kuvhara.
Iyo hormone progesterone panguva yekuzvimba ndiyo iyo huru uye inotarisira kuchengetedza pamuviri. Iyo inobudiswa nehutachiwana hutsva hwekuguma-hutsika, huchati huchange huri panzvimbo yeyo kuputika kwemapurisa. Progesterone inonzi hormone inobata pamuviri, kana iyo yakawanda isina kukwana, pamuviri unogona kuvhiringidzika panguva yekutanga. Kusvikira mavhiki 14-16 ekuberekwa, progesterone inoberekwa nehutano muviri , uye mushure mekunge panguva iyi-nepa placenta.
Imwe hormone inoberekwa panguva yekuzvitakura inonzi chorionic gonadotropin, iyo inobudiswa nevillus yechirion uye inotanga kuonekwa kubva mumazuva mana ekudzivirira, apo mucheche unotanga kuiswa muchibereko.
Izvo zvisingaiti zvepabonde zvinokanganisa pamuviri
Panguva yekuzvitakura, kune kuwedzera kwekugadzirwa kwe thyrotropic (TTG) uye adrenocorticotropic (ACTH) mahomoni. Utachiona hunokurudzira hormone paunenge uchiita pamuviri hunoita kuti utachiona huve nehutano uye hunoita kuti kuwedzerwa kwehomoni yekemikari. Nokudaro, panguva yepamuviri, kune vamwe vakadzi, chirwere chetachiona chinogona kuwedzera, uye avo vane matambudziko kune chikamu chetachiona, kukura kwavo kunowanikwa. Utachiona hwehutachiona hunogona kuva chikonzero chekubvisa pamuviri pakarepo, uye unyengeri hunotungamirira kukanganisa kwehutano huri mumwana.
Kubva kune rumwe rutivi rwezvinyorwa zvinonzi adrenal, kunewo zvimwe zvakajeka kuchinja. Mazhinji ehomoni ye cortical layer ye adrenals inobudiswa zvakanyanya. Zvakakosha kucherechedza kuti mumadzinza adrenal, mukadzi anobereka mahomoni ehurume, izvo zvinotungamirirwa neimwe enzyme zvinova mahomoni evanhukadzi. Kana nhamba ye enzyme iyi isingakwanisi, mari yacho
Nzira yekuziva sei mazinga ehomoni panguva yekudzivirira?
Nzira iri nyore yekuziva kuti mahomoni eHCG panguva ipi yekuzvitakura ndeyekubatsira kwemaitiro akange aripo - izvi zvinoitwa nekubatsirwa kwekuongorora musha (kusarudza kwepamusoro ye chorionic gonadotropin murwizi). Zvimwe zvinodzidzisa ndezvokugadzirisa kwemahomoni muropa mune ma laboratori chaiwo.
