Understanding Male Hormones: Testosterone, DHT & More

In males, the predominant hormones are testosterone, dihydrotestosterone (DHT), and androstadienedione. These hormones are responsible for the development and maintenance of male reproductive structures and secondary sexual characteristics.

Testosterone is the primary male sex hormone produced in the testicles. It plays a crucial role in the development of male genitalia and male sexual characteristics, such as a deep voice, facial hair, and muscle mass. Testosterone also affects libido, sexual desire, and energy levels.

Dihydrotestosterone (DHT) is derived from testosterone through the action of the enzyme 5-alpha-reductase. It is the active form of testosterone in many tissues, particularly the prostate gland, hair follicles, and sebaceous glands. DHT is essential for the development of the penis, prostate, and external genitalia in males during puberty. It also plays a role in male pattern baldness and prostate enlargement (benign prostatic hyperplasia).

Androstadienedione is another androgenic hormone produced in the testicles and adrenal glands. It is less potent than testosterone and DHT but can be converted into testosterone and DHT in the body. Androstadienedione plays a role in maintaining libido and sexual function.
