Document Summary
Gonads or primary sex organs are the testes and the ovaries. Gonads produce sex cells or gametes and secrete sex hormones. Joint purpose of the two is to produce offspring. Male games produce sperm and deliver them to women"s reproductive tract. Once fertilized, it becomes an embryo, later called the fetus and keeps developing until birth. These hormones also influence the growth and development of many other organs and tissues of the body. Testes or male gonads which both have an exocrine (sperm producing) function and endocrine (testosterone producing) function. Fibrous connective tissue capsule called tunica albuginea surrounds each teste. Extensions of this capsule divide into wedge shaped lobules. Each lobule has 4 tightly coiled seminiferous tubules seminiferous tubules of each lobe empty sperm into another set of tubules the rete testes. Sperm travel though the rete testes to enter the first part of the duct system, the epididymis.
