A sperm cell, is the haploid cell that is the male gamete. It joins an ovum to form a zygote. A zygote can grow into a new organism, such as a human being.
Sperm cells contribute half of the genetic information to the diploid offspring. In mammals, the sex of the offspring is determined by the sperm cells: a spermatozoon bearing a Y chromosome will lead to a male (XY) offspring, while one bearing an X chromosome will lead to a female (XX) offspring ( the ovum always provides an X chromosome).
