The primary sex organs are called gonads, and male and female bodies both have them. The testes are the gonads for males, and the ovaries are the gonads for females. The gonads can produce hormones and cells, making them mixed glands.
The testes, being the main sex organs of the males, produce the sex hormone testosterone. This hormone is vital to the maintenance and development of the secondary sex organs. Testosterone is also responsible for the intensity of sexual desires and sexual characteristics and development in males.
The ovaries of the females are a part of the endocrine system because they facilitate endocrine functions. Aside from that, however, the ovaries are also tasked with the production of estrogen and progesterone (the female sex hormones). The corpus luteum and the ovarian follicles known as graafian produce estrogen. But, estrogen production is also seen in he adrenal cortex, the placenta and even in the male testes. This hormone has to take care of so many functions, which are as follows: the control of sexual desire, the development of the secondary sex organs in females, the management of sex organs and characteristics, and the facilitation of the uterus’ changes. Progesterone is secreted by the corpus luteum. This hormone is only useful before and throughout pregnancy. It prepares the uterus to accept the fertilized egg and thereafter safeguards the egg from experiencing unplanned abortion.
