Research on women and testosterone has been limited, but as more is done, experts are seeing that the hormone affects the female sex drive, just as it does the male. It also plays an essential ...
ABP is essential to concentrating testosterone in levels high enough to initiate and maintain spermatogenesis. Intratesticular testosterone levels are 20–100 or 50–200 times higher than the concentration found in blood, although there is variation over a 5- to 10-fold range amongst healthy men.
The onset of puberty is controlled by two major hormones: FSH initiates spermatogenesis and LH signals the release of testosterone, [19] an androgen that exerts both endocrine activity and intratesticular activity on spermatogenesis. LH is released from the pituitary gland, and is controlled by pulses of gonadotropin-releasing hormone.
Testosterone is also synthesized in far smaller total quantities in women by the adrenal glands, thecal cells of the ovaries, and, during pregnancy, by the placenta. [158] In the testes, testosterone is produced by the Leydig cells. [159] The male generative glands also contain Sertoli cells, which require testosterone for spermatogenesis.
