Primary sexual characteristics are the physical attributes directly related to reproduction that are present at birth. In males, these include structures like the penis and testes, while in females, they include the vagina, ovaries, and uterus. These characteristics differentiate male and female bodies and are essential for sexual reproduction. They are distinct from secondary sexual characteristics, which develop during puberty.
