The testes (testicles) are two egg-shaped organs housed within the scrotum that play a central role in male fertility and function. According to studies performed in mice, the final stages of sperm maturation appear to be regulated by a gene known as Katnal1, which is expressed by the Sertoli cells that support and nourish immature sperm within the walls of the seminiferous tubules (the site of spermatogenesis). It also is the job of the epididymis to bring the sperm to maturity, since the sperm that emerge from the testes are immature and incapable of fertilization.

The epididymis is a duct-like organ that connects the testis to the vas deferens and is comprised of four anatomical regions: the initial segment, caput, corpus, and cauda. Sperm maturation occurs during epididymal transit by the interaction of sperm cells with the unique luminal environment of each epididymal region. A fundamental change that occurs during capacitation is alkalinization of sperm cytoplasm, in which the intracellular pH levels increase, particularly in the flagellum.
