The sex hormones are important in the development of the primary and secondary sexual characteristics in both males and females. The two main classes of sex hormones are the androgens and the estrogens. The androgens are derived from testosterone while the estrogens are derivatives of estradiol.
The androgens are the male sex hormones. They are responsible for the development of the primary and secondary sexual characteristics in males. The estrogens and the progesterone are the female sex hormones. They control the development of the primary and secondary sexual characteristics in the females.
The male sex hormone is the testosterone. The testosterone is synthesized by the leydig cells of the testes. Testosterone is responsible for the development of the secondary sexual characteristics in men. This hormone is very essential for the production of sperm.
The estrogens are responsible for the development of the female secondary sexual characteristics such as development of breast, further development of the uterus, vagina, etc
Aside this, the estrogens also have non-reproductive effects. The progesterone plays a critical role in the menstrual cycle and pregnancy. The production of estrogens is stimulated by the Follicle Stimulating Hormone (FSH). Follicle Stimulating Hormone is controlled by the hypothalamus via Gonadotropin Releasing Hormone (GnRH).
The synthesis of progesterone is also stimulated by Lutenizing Hormone. Just like the Follicle Stimulating Hormone, the leteinizing horumone is in turn stimulated by the hypothalamic Gonadotropin Releasing Hormone.
