Prostate-specific antigen 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. Follicle-stimulating hormone is necessary for sperm production (spermatogenesis), and luteinizing hormone stimulates the production of testosterone, which is also needed to make sperm. The main function of the testes is producing and storing sperm. The acrosome contains proteins that help the sperm penetrate the outer shell of an egg. The midsection of the sperm contains energy producing mitochondria. These specialized structures provide the energy necessary for the sperm cell to move.
