The reproductive system is necessary for the production of new living organisms. The reproductive system is comprised of male and female reproductive organs and structures. Both male and female reproductive organs have internal and external structures.
Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates. Most plants are also hermaphrodites. Historically, the term hermaphrodite has also been used to describe ambiguous genitalia and gonadal mosaicism in individuals of gonochoristic species, especially human beings.

The images below illustrate the male and female body parts that are involved in sexual activity and reproduction. These body parts are also commonly referred to as genitals, reproductive organs, or sex organs. The male body has sexual organs both inside and outside the body. The internal organs include the epididymis, vas deferens, seminal vesicles, and prostate, and the external organs include the penis and testicles.
The male sexual organs include the penis, testicles and prostate gland. The penis is partly inside and partly outside the body. These include skin, muscle, blood vessels and nerves.
Humans are sexual, meaning that both a male and a female are needed to reproduce. Each is equipped with specific organs capable of producing specific cells needed to procreate. The average age of puberty for males is around
The anemonefish is a gender-bending marvel. It starts out as a male, but can switch to female when circumstances allow, for example, when the only female present dies or disappears. In a new study, researchers found that the male-to-female sex-change occurs first in the fish's brain and only later involves the gonads -- sometimes after a delay of months or years.
The more usual term is genitals. In men this sex organ is called a testicle, and in women it is called an ovary. British very informal testicles.
A sex organ or reproductive organ is any part of an animal's body that is involved in sexual reproduction. The reproductive organs together constitute the reproductive system. The testis in the male, and the ovary in the female, are called the primary sex organs.
Sexual intercoursealso called coitusor copulationreproductive act in which the male reproductive organ in humans and other higher animals enters the female reproductive tract. If the reproductive act is complete, sperm cells are passed from the male body into the female, in the process fertilizing the female egg and forming a new organism. In some vertebrates, such as fisheggs are laid outside of the body and fertilized externally. To accomplish internal copulation certain body and organic adaptations are necessary.
