Prolactin muvarume

Prolactin inonzi hormone inobatanidzwa mukugadzirisa kwemaitiro emadzimai panguva yekudzivirira uye munguva yekuyamwisa. Zvinotendwa kuti iyi hormone inoberekwa chete mumutumbi wevakadzi, asi mumuviri wemurume inowanikwawo. Mune varume, inokurudzira kuumbwa uye kukura kwakanaka kwepermatozoa, pamwe nekugadzirwa kwe testosterone.

Chii chinonzi prolactin?

Prolactin inonzi polypeptide hormone inogadzirisa zvivako zvinotevera:

• Lactotropic masero elobe anterior ye planditary gland;
• Chimwe chinyorwa chepa placenta;
• Iyo mucheche membrane yechibereko (endometrium).

Basa guru reprolactin ndiko kukura uye kukura kwezamu, pamwe nekukurudzira kwakasimba kwe lactation. Masayendisiti anotaura kuti prolactin inodzvinyirira mahomoni, nokuti nekuwedzera kudzvinyirira, kushungurudzika kwepfungwa, kuneta kana kukanganisa kwezvimwe zvekunze zvisina kunaka, zvarinowanikwa mumuviri womunhu zvinowedzera.

Pasinei nechokwadi chokuti kusvikira zvino prolactin inoreva mahomoni asina kudzidza (hapana ruzivo pamusoro pekubatanidzwa mune zvimwe zvirongwa zvemagetsi), mamwe mashoko pamusoro payo akawana nguva yose yekutsvakurudza. Izvi zvidzidzo hazvirevi chete basa reprolactin semutevedzeri wemafungiro ekuberekwa kwevakadzi, uyewo vakakanganisa kubatanidzwa kwei polypeptide mumagadzirirwo emagetsi anongoratidzirwa chete emunhu wenyama. Izvi zvinosanganisira, semuenzaniso, kuti prolactin mumarume inobata kugadzirwa kwechinyakare chinokwana spermatozoa. Nokuda kwezviito zvehuropi basa, varume vanodawo prolactin.

Ingofungidzira kuti mumuviri wemurume mabasa ehomoni iyi akafanana neanororal metabolism mumuviri wechikadzi. Mafungiro akadaro angave akaipa. Physiologically, prolactin muvarume, semadzimai, inobudiswa mumutambo wekare wepituitary gland. Mukuwedzera, mune izvi zvinosanganisira chimwe chimiro chehuropi hwevanhu - hypothalamus. Munenge mishonga yose nhengo dzomuviri womunhu dzine prolactin molecule, uyewo zvinogamuchirwa zvinosangana nehomoni iyi. Zvisinei, sayenzi haisati iine ruzivo rwakajeka pamusoro pebasa reprolactin uye nhengo yaro mumabasa anoitika munhengo idzi.

Prolactin muvarume nevakadzi: kusiyana

Sezvo mune hutachiona hwehutachiona uye hutano hwezvipombwe zvevarume nevakadzi pane mutsauko mukuru, munyaya iyi, chokwadi, basa reprolactin richave rakasiyana. Kunyanya, kusiyana kunozozviratidza pachavo nemararamiro, zvirwere, nezvimwewo. Semuenzaniso, chiratidzo chekuzvitakura mumudzimai panguva yekuongororwa kuchava kuvapo kwehuwandu hweprolactin, nokuti nevhiki rechisere rokutora chikwata chake chichawedzera zvinoshamisa.

Mumamiriro ezvinhu akadai, hormone prolactin muvarume inowedzera uwandu hwe testosterone, uye mumamiriro ezvinhu akadaro seprolactinemia isingaperi, iyo inokonzerwa nekushandurwa mukati mekuvhara kwemahomoni ekureruka, kubudiswa kwe testosterone nemasero eLeydig akatsika. Kuumbwa kwe androgens kwezvinyorwa zvinonzi adrenal (iyo iyo cortex yemhesi) zvakananga zvichienderana nehuwandu hweprolactin.

Prolactin inowedzera: zvikonzero

Kuwedzera kwemasimba eprolactin mumarume kunoratidza zvirwere zvakasiyana-siyana, uye ine chirwere chechipatori chaiyo. Zvirwere izvi zvinosanganisira zvipembenene zvakasiyana-siyana zvepituitary gland. Zviratidzo zvezviratidzo zvevarume nevakadzi zvakasiyana. Muvanhu, kuwedzera kwehuwandu hwehomoni iyi kunotungamirira kusina simba, kupera uye kunonyorera kwemakumbo, uye mumadzimai - kunokonzera kusakanganiswa kwemwedzi, kusvikira pakupera. Chirwere chemakiriniki akadaro chinogona kuva uye kana chirwere ichi chinokanganisa chete glands zvepabonde. Semuenzaniso, muvakadzi i polycystic ovary, uye mumarume, maererano-prostate adenoma.
