What term is used to describe the male reproductive cell?

The term used to describe the male reproductive cell is "sperm." Sperm cells are produced in the male reproductive system, specifically in the testes, through a process called spermatogenesis. They are typically motile and have a flagellum that enables them to swim towards the female reproductive cell, the ovum, for fertilization.

In contrast, the other terms provided refer to different aspects of human reproduction. The ovum is the female reproductive cell, the zygote is the initial cell formed when a sperm fertilizes an ovum, and the embryo refers to the early stage of development after fertilization. Understanding the specific roles of these terms clarifies the unique function of sperm in the reproductive process.
