Reproductive organ

Reproductive organ

Reproductive organs, also known as sex organs, are parts of an organism that directly involve in the process of reproduction. Many species, both plants and animals, have sexual specialization, and their populations are divided into male and female individuals. Complex reproductive systems have evolved in animals to produce offspring.

Male reproductive organs

The main male reproductive organs in humans and many other animals are the testes (singular: testis), which produce sperm, and the penis, which delivers sperm to the female reproductive system.

Testes

The testes are two oval organs that produce sperm and the male hormone testosterone. They are located in the scrotum, a pouch of skin that hangs outside the body behind the penis.

Penis

The penis is the male organ for sexual intercourse. It has three parts: the root, which attaches to the wall of the abdomen; the body, or shaft; and the glans, which is the cone-shaped end of the penis.

Female reproductive organs

The main female reproductive organs are the ovaries, which produce eggs, and the uterus, which receives the fertilized egg and provides a place for the fetus to develop.

Ovaries

The ovaries are two oval organs located in the female pelvic cavity. They produce eggs and the female hormones estrogen and progesterone.

Uterus

The uterus, or womb, is a hollow, pear-shaped organ located in a woman's lower abdomen between the bladder and the rectum. It is where the fertilized egg implants and the fetus develops.
