Unique for its role in human reproduction, a gamete is a specialized sex cell carrying 23 chromosomes—one half the number in body cells. At fertilization, the chromosomes in one male gamete, called a sperm or spermatozoon , combine with the chromosomes in one female gamete, called an oocyte. The function of the male reproductive system Figure 1 is to produce sperm and transfer them to the female reproductive tract. The paired testes are a crucial component in this process, as they produce both sperm and androgens, the hormones that support male reproductive physiology. In humans, the most important male androgen is testosterone.

The sperm ducts have a network of structures that belong to the genitourinary and reproductive systems. The tubules are intertwined to form the rete testis testicular network. From the testicular network of each testicle begin the efferent ducts that reach the epididymis small elongated body on the top-rear edge of the testicle , and the final tract of the sperm ducts is located between the efferent ducts of rete testis and the vas deferens main transport channel for semen. The tracts or spermatic cords represent the universe of the vas deferens and blood vessels and nerves that are flanked in its course. The ejaculatory ducts , which are essential for the transport of sperm, extend through the prostate gland and are included in the prostatic urethra. The tissue that lines the inside wall of the sperm ducts is a moist layer of mucous membrane. The mucous membrane is surrounded by three layers of circular and longitudinal muscle fibres, which facilitate muscle contractions of the ducts.
