In the human male, the urethra is about 8 inches (20 cm) long and opens at the end of the penis. The urethra provides an exit for urine from the bladder as well as semen from vasa differentia during ejaculation.
Thus, it knows as a urogential duct. It has three regions. Vasa defferentia collects sperm form inside the testis and transfers them epididymis through rete testis. Ureters are the tubes that convey urine from the kidney to urinary bladder.
