The reproductive system is necessary for the production of new living organisms. The ability to reproduce is a basic characteristic of life. In sexual reproduction, two individuals produce offspring that have genetic characteristics from both parents. The primary function of the reproductive system is to produce male and female sex cells and to ensure the growth and development of offspring.
The reproductive system is comprised of male and female reproductive organs and structures. The growth and activity of these organs and structures is regulated by hormones. The reproductive system is closely associated with other organ systems, particularly the endocrine system and urinary system.
Both male and female reproductive organs have internal and external structures. Reproductive organs are considered to be either primary or secondary organs. The primary reproductive organs are the gonads (ovaries and testes), which are responsible for gamete (sperm and egg cell) and hormone production.
The other reproductive structures and organs are considered secondary reproductive structures. Secondary organs aid in the growth and maturation of gametes and developing offspring.
