I-testosterone kwama-hormone umsebenzi walo emzimbeni womuntu

Kubantu, kukhona indlela ezimbili eziyisisekelo isiqondiso kwezitho izinhlelo: kwemizwa kanye humoral. Eyokuqala yalezi Kwenziwa, sibonga innervation obuningi yangaphakathi izitho, izindlala, kwakheka imithambo yegazi kanye nemisipha nemisipha.

Mshini yesibili kungenxa ezikude hormone okuthiwa i isinyathelo lapho akhiqizwa nezindlala endocrine, bese zidluliselwa egazini ku izicubu nje kumbe izitshengiselo isitho. Ngakho, i-testosterone hormone, le androgen oyinhloko, ikhiqizwa nengcosana ngu cortex adrenal, futhi phezu okuvela ukuthomba kubafana iyaqala ngenkuthalo akhiqizwa testes, wabe excretory Amapayipi we ndlala ikhishwe lingene egazini futhi eminye kuyalithinta uhlelo zemisipha, futhi futhi ku umzimba esibindini. Ngokusho isimiso lwempendulo testosterone bayokwazi ukuqondisa ukukhiqizwa ezinye hormone (njengaku besifazane futhi umzimba besilisa).

testosterone umsebenzi

Testosterone amazinga e amadoda, yebo, iphakeme kakhulu kunanoma ezingeni yayo abesifazane, ngoba emzimbeni wesilisa ke wenza imisebenzi ngaphezulu: e bathombe abafana ngenxa yethonya lakhe, Ukwakheka kwezitho okuthiwa izici yesibili ngokobulili, okungukuthi, isandiso "ekuhlephuleni" izwi ibhande lamahlombe ngokuziqhathanisa ukhalo, ukwandisa yemisipha bone compaction nokuvuthwa of gametes ku gonads.

Ngo amadoda esekhulile, nakho kunomthelela nokugcinwa umsebenzi zocansi, okungukuthi, isifiso sobulili, potency yakha ukuziphatha kobulili psychophysiological. I-testosterone i-hormone ekhiqizwa abesifazane: e cortex adrenal, amaqanda futhi ukuguquka estrogen. Anakho umphumela inhibitory ku nokuvuthwa of follicle wesibeletho futhi silawule ukukhiqizwa estradiol futhi estrone ngokusebenzisa eksisi hypothalamic-pituitary-adrenal. Lapho hypersecretion abesifazane yakhe noma ukuphatha yokufakelwa izidakamizwa equkethe hormone (ama eziningi Anabolic), masculinization kwabesifazane eba, kubonakala ushona izwi, kukhuphuke umzimba izinwele, ukuthuthukiswa muscle ekuziphatheni okunobudlova.

WokuLawula uketshezi kwe-testosterone

Kukhona izindlela eziningana ezithinta ezingeni testosterone. Norma amadoda akhe kuyinto 11-33 nmol / ilitha, futhi abesifazane - 0,24-2,7 kuphela. Kulokhu, lo testosterone i-hormone egazini e amafraktjhini amabili: mahhala futhi nakanjani ukuthutha amaprotheni-albumin futhi globulin ethize uyakwazi ngibopha hormone ocansini (SHBG). Nokho, umsebenzi begazi ububonisa kuphela khulula (2% wezindleko) ne-testosterone nakanjani-albumin. Ngemva kweminyaka engu-30-35 e amadoda testosterone hormone bioavailability yayo, kanye ingxenyenamba Imininingwane, bathambekele wehlise ngesilinganiso esingaba 2-3% / ngonyaka, kanti lapho esekhulile ezingeni kwe-testosterone asebenzayo kuyehla izikhathi 5 (kuqhathaniswa kwentsha) kanye Imininingwane - izikhathi 2.5. Ngokwemibiko ethile, lokhu akuyona nje ukwehla kancane kancane uketshezi yayo, kodwa kukhuphuke sesibopho ukuthobisa SHBG, ingxenyenamba ngaleyo ndlela bioavailable ingasebenzi.
