The word "genitals" refers to the reproductive organs of an organism. In humans, this includes the external parts such as the penis and scrotum in males, and the vulva and clitoris in females. These organs are involved in sexual reproduction and also play roles in sexual activity and pleasure.
The term "genitals" comes from the Latin word "genitalis," which means "pertaining to generation or reproduction." The root of the word is "genitus," the past participle of "gignere," meaning "to produce" or "to generate."
