Both sperm and urine are expelled from the body by the urethra. Sperm are stored behind the seminal vesicles and when the signal to ejaculate is encountered, this enters the ejaculatory duct and is ejected into the urethra through the opening of the ejaculatory tubule above the seminal mound and out of the body. Urine is stored within the bladder, and when the signal to urinate occurs, urine enters the posterior urethra, passes through the seminiferous tubercle into the anterior urethra, and then exits the body. Therefore, both sperm and the first half of urine are expelled from the body by the urethra. The second half of sperm does not enter the bladder or the posterior urethra, but enters the seminal vesicles through the opening of the ejaculatory duct. Urine enters the posterior urethra from the bladder, flows through the seminal mons and then exits the body through the anterior urethra. Sperm and urine are discharged from the same place, and the place of discharge is called the urethra, but the sperm and the latter part of the urine have different pathways.
