| Seminiferous tubules | Thin, coiled structures in the testis where sperm are produced. |
| Vas Deferens | A sperm-carrying tube that begins at the testis and ends at the Urethra |
| Seminal Vesicles | Small glands adjacent to the terminals of the vas deferens that secrete an alkaline fluid (important role in male fertility by contributing to the formation of healthy semen and functional sperm. This is where 60% of semen comes from. |
