Science glossary film: Sperm

Male reproductive cells, also referred to as the male gametes. Human sperm contain 23 single chromosomes. This genetic material is contained in the head of the sperm, which also has a midsection, and a tail that propels them in a swimming motion. The semen produced by the male reproductive tract, as a medium for sperm, typically contains over 100 million sperm cells, all of which have but one purpose: to fertilize the single available egg.
