Female 28-day hormonal cycle (menstruation):About 95% of the testosterone in males is produced by the Leydig (interstitial) cells of the testes and the rest is produced by adrenal glands. Among FSH, LH and Testosterone, testosterone is the most important hormone in males which plays a major role in the normal growth and development which includes the development of the body, facial hair, the functions of the larynx which in turn leads to the change in the voice after puberty, the enlargement of the genitals and the secondary sex characteristics in men. |
