Sperm is a male reproductive cell produced in the testicles. It is crucial for human reproduction. Sperm is mainly composed of a head, which contains the genetic material, and a long, thin tail that enables it to move.
During sexual intercourse, sperm is ejaculated into the woman’s vagina and travels towards the egg. If a sperm successfully fertilizes the egg, an embryo is formed, initiating the development of a new human being.
Sperm is essential for transmitting genetic information from parents to their offspring.
