背景介紹：
睪酮是一種C-19類固醇，男性從睪丸和腎上腺皮質分泌，女性從腎上腺皮質和卵巢分泌。睪酮也是由雄烯二酮的外周組織產生的，這在男性中沒有什么生理意義，但在女性中，大約有一半的循環睪酮是從這個來源產生的。睪酮測量主要用于男性性腺功能減退和女性高雄激素狀態的臨床評估。
睪酮在血液中循環與三種蛋白質結合：性激素結合球蛋白(60-80%)、白蛋白和皮質醇結合球蛋白。只有大約1-2%的總循環睪酮保持不受約束或自由。盡管目前仍在研究中，但大多數研究人員都接受將游離睪酮測定作為生物活性成分的一種衡量標準。建議采用游離睪酮測定，以克服運輸蛋白變化對總睪酮濃度的影響。
Testosterone is a C-19 steroid secreted from the testis and the adrenal cortex in men and from the adrenal cortex and ovaries in women. Testosterone is also produced by peripheral tissues from androstenedione, which is of little physiological signi? cance in men, however in women about half of the circulating testosterone is derived from this origin. Testosterone measurements are used mainly for clinical evaluation of hypogonadism in males and hyper-androgenic states in females.
Testosterone circulates in the blood bound to three proteins: sex hormone binding globulin (60–80%), albumin and cortisol binding globulin. Only about 1–2% of the total circulating testosterone remains unbound or free. Even though it is still under investigation, most researchers accept the free testosterone determination as a measure of the biologically active fraction. Free testosterone determinations are recommended to overcome the influences caused by variations in transport proteins on the total testosterone concentration.
