In the cytoplasm of goal cells, testosterone or dihydrotestosterone binds to distinct androgen receptors, as well as hormone-receptor complexes enter the mobile nucleus, exactly where they modulate protein synthesis by influencing the rate at which particular genes are transcribed (

[86] Married Males who interact in bond-servicing things to do like paying out the working day with their partner or youngster haven't any different testosterone amounts as compared to occasions when they do not engage in these types of functions. Collectively, these results suggest that the presence of competitive functions instead of bond-upkeep pursuits is much more pertinent to adjustments in testosterone stages.[87]

Testosterone has various significant actions. It provides adverse feed-back inhibition within the secretion of gonadotropin-releasing hormone with the hypothalamus and also the secretion of luteinizing hormone from your pituitary gland. In addition it directs the development in the embryonic Wolffian ducts in the vas deferens (ductus deferens) and seminal vesicles and stimulates the development of muscle and bone.

Just about every mammalian species examined demonstrated a marked boost in a male's testosterone stage upon encountering a novel

Testosterone is often a steroid within the androstane class that contains a ketone and also a hydroxyl team at positions a few and seventeen respectively. It is actually biosynthesized in a number of measures from cholesterol and is also transformed in the liver to inactive metabolites.[8] It exerts its action by means of binding to and activation on What everyone is talking about the androgen receptor.[8] In people and most other vertebrates, testosterone is secreted mostly with the testicles of males and, into a lesser extent, the ovaries of females.

Androgen receptors take place in a number of vertebrate entire body program tissues, and the two males and females respond similarly to identical concentrations. Enormously differing quantities of testosterone prenatally, at puberty, and during lifestyle account for a share of Organic variances in between males and females.

與其他類固醇激素一樣，睪酮是由膽固醇所衍生的。男性睪丸可以產生大量睪酮，女性卵巢、胎盤及男性或女性的腎上腺網狀帶亦會分泌少量的睾酮。

睪酮對成人的影響，對男性比較明顯，但對男女兩性都同樣重要。隨著年紀漸長，睪酮的份量下降，這些影響亦隨之而減少。這些影響包括：[來源請求]

概括地说，雄激素助长蛋白质的合成及拥有雄激素受体的组织的生长，睾酮的效用可以分为合成代谢及雄性化效应。合成代谢效应包括肌肉质量及力量的增长、增加骨质密度及强度、刺激线性生长及骨骼成熟等。雄性化效应则包括性器官的成熟（尤其是阴茎及胎儿阴囊的生成）、出生后（通常是在青春期）声线的转沉、胡须及体毛的生长等。这些效应一般都是男性的第二性征。
