Document Summary
The male reproductive system involves a variety of structures working in synchrony to create and transport the male gamete cell, sperm. Sperm are produced in the testes and transported through a duct system to reach the external world. Sperm are male reproductive cells that carry paternal genetic information for reproduction. Head: the head is flat and oval. The nucleus contributes either an x or y chromosome to the fertilization process. The acrosomal cap contains enzymes that are released prior to fertilization to help the sperm pass through the layers of the egg. Neck: the neck connects the head to the mid-piece. Midpiece: the midpiece is a continuation of the neck with a mitochondrial collar that helps produce energy. Tail: the tail or flagellum is the source of movement for the sperm. Fact: in a single ejaculation, there are approximately 100 million sperm present. The testes are the site of sperm creation and development in the male reproductive system.
