The female sex is defined as the one which produces the larger [[gamete]] (the egg) and which typically bears the offspring. In contrast, the male sex has a smaller gamete (sperm) and rarely bears offspring.

Sex can also refer to sexual intercourse, the physical act of reproduction, also known as "sexual relations" or "having sex." - where the male penis enters the female vagina, and ejaculates sperm cells into the female's reproductive tract. This might eventually cause a sperm cell to fertilise an egg cell, and thus reproduce. Apart from the purely reproductive part,  sex in various forms(anal, oral, S/M and so on) is an important part of human social life, no longer limited to marriage(except for some religious fundamentalist societies).

In some animals, sex may be assigned to specific structures rather than the entire organism. Earthworms, for example, are normally [[hermaphrodites]].
