Detailed explanation-2: -The external urethral orifice is the external opening (or meatus) of the urethra. It is where urine exits in both males and females. In males, it is also where the semen is ejected during ejaculation. The male external urethral orifice is located on the glans penis, at the tip, at the junction with the ferenular delta.
