Female is the sex of an organism, or a part of an organism, which produces egg cells. The "egg cell" is defined as the larger gamete in a heterogamous reproduction system, while the smaller gamete is produced by the male. A female individual cannot usually reproduce without sexual intercourse with a male, although some exceptions exist.
A common symbol used to represent the female gender is ♀ (Unicode: U+2640), a circle with a small cross underneath. This symbol also represents the planet Venus and may be seen as a stylized representation of the goddess Venus' hand mirror.
