What is the male gamete called?

The male gamete is referred to as sperm. In human reproduction, gametes are the reproductive cells that unite during fertilization to form a new organism. Males produce sperm cells which are typically motile and specialized for reaching and fertilizing the female gamete, which is the ovum or egg.

The ovum is the female counterpart and plays a different role in reproduction, as it is larger and immobile compared to the sperm. The term 'germ cell' refers more broadly to cells that can give rise to gametes but does not specify the male contribution specifically. Therefore, sperm is the correct term used to identify the male gamete that participates in fertilization.
