Antibiotics Swelling or herniation of the sac surrounding the testes is called: The widespread nature of sexual reproduction in animals has raised intriguing questions concerning the evolutionary origins of sperm. 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.
