Dihydrotestosterone (DHT) is a metabolite of testosterone, and a more potent androgen than testosterone in that it binds more strongly to androgen receptors. It is produced in the skin and reproductive tissue. A4 and testosterone can also have an extra hydroxyl (-OH) or keton (=O) group bound on position 11.
Testosterone is the primary male sex hormone and androgen in males. [3] In humans, testosterone plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.
After the testes have differentiated, male sex hormones, called androgens, are secreted from interstitial cells (cells of Leydig). The major androgens secreted by these cells is testosterone and secretion begins 8 to 10 weeks after conception.
Androstenedione (Andro): an androgenic steroid produced by the testes, adrenal cortex, and ovaries. While androstenediones are converted metabolically to testosterone and other androgens, they are also the parent structure of estrone. Dehydroepiandrosterone (DHEA): It is the primary precursor of natural estrogens.
DHT is an androgen produced naturally by your body. It’s created as a byproduct of the sex hormone testosterone, meaning your body regularly converts a small amount of the testosterone you ...
Leydig cells release a class of hormones called androgens (19-carbon steroids). [8] They secrete testosterone, androstenedione and dehydroepiandrosterone (DHEA), when stimulated by the luteinizing hormone (LH), which is released from the anterior pituitary in response to gonadotropin releasing hormone which in turn is released by the hypothalamus.
More specifically, androgenetic alopecia is caused by a genetic sensitivity to an androgen called DHT. Your body creates DHT as a byproduct of testosterone, the main androgen hormone in the male body.
DHT binds to androgen receptors in your hair follicles, causing miniaturization and gradual hair loss. With finasteride blocking 5-alpha-reductase, less testosterone is converted into DHT, meaning ...
