Detailed explanation-1: -Urethra: The urethra is the tube that carries urine from the bladder to outside of your body. In males, it has the additional function of expelling (ejaculating) semen when you reach orgasm.

Detailed explanation-2: -Urethra-this is a tube that extends from the bladder to the external opening at the end of the penis. The urethra carries both urine and sperm. Seminal vesicles-these are 2 small glands above the prostate gland that make up much of the fluid in semen.

Detailed explanation-3: -During sexual arousal, muscles at the base of the bladder contract in order to close off the passageway from the bladder into the urethra, the tube through which urine and semen leave the body. This makes it impossible for urine to be released during ejaculation.
