The Reproductive System

The human body is a complex system of bone, tissue, organs and fluids. Chemicals produced by glands – cells or organs that secrete fluids – regulate many bodily functions. The pituitary and the ovaries, glands that secrete hormones related to sex and fertility, play a major role in human reproduction.

The pituitary gland, in both males and females, is responsible for producing hormones that travel through the bloodstream and ultimately regulate the maturation and release of gametes (sperm and eggs respectively). In the female, the ovaries produce estrogen, progesterone and other hormones affecting the sex drive and fertility. Testosterone and other hormones, produced by cells in the male’s genital area, contribute to the production of sperm and his ability to achieve and sustain an erection during intercourse.
