The testes are two small oval shaped organs located in the scrotal sac outside the body, one on either side of the penis. They are responsible for producing sperm and secreting testosterone. Sperm is produced in the seminiferous tubules. They then move through the epididymis where they mature and combine with other fluids to form semen, until they reach the vas deferens, where they await ejaculation.
