External genitalia refers to the visible reproductive organs located outside the body. In males, this includes the penis and scrotum, which houses the testes. In females, the external genitalia consist of the vulva, which includes structures such as the labia, clitoris, and the opening of the vagina. These organs play essential roles in reproduction, sexual function, and protection of internal reproductive structures. They also contribute to sexual arousal and pleasure. Understanding external genitalia is important for health education and awareness regarding human anatomy and reproductive health.
