Most of the time, it is secreted by the adrenal glands, and its main function is to strengthen bones and improve immunity. Free testosterone has a wide range of applications in clinical medicine. It is an important drug molecule for some hormonal diseases caused by endocrine hormones and diseases in which testosterone levels are not within the normal range.

A small amount of testosterone is also secreted by the adrenal glands. It is the main male sex hormone and anabolic steroid.

Decreased testosterone: trisomy 21, uremia, myotonic dystrophy, liver dysfunction, trapped testis, primary or secondary hypogonadism (Klinefelter syndrome, Kallman syndrome, etc.), after discontinuation of androgen therapy, etc.
