Female Urethra

Male Urethra

In males, the urethra is longer and has three parts: the prostatic urethra, the membranous urethra, and the spongy (penile) urethra. It passes through the prostate gland and the penis. The male urethra is also responsible for carrying semen during ejaculation.

Functions of the Urethra
