Genitalia refers to the reproductive organs of an organism. In humans, these include the external and internal structures involved in reproduction. For males, the primary external genitalia are the penis and scrotum, while females have the vulva as the external part, which includes the clitoris and labia. In addition to external features, genitalia also encompass internal organs such as the testes in males and the ovaries in females. These organs play crucial roles in producing gametes—sperm in males and eggs in females—and are essential for sexual reproduction.
