Which Gender Has Eggs?

Females have eggs.

Understanding Female Reproductive Biology

The question "Which gender has eggs?" refers to the biological process of reproduction. In humans and most other sexually reproducing species, females possess eggs, also known as oocytes. These are the female reproductive cells that, upon fertilization by a male's sperm, can develop into a new organism.

  • Egg Count at Birth: A female is born with a finite number of eggs. At birth, a normal female ovary contains approximately 1-2 million oocytes.
  • Egg Decline: The number of eggs steadily decreases throughout a female's life, with a continuous decline occurring each month.
  • No New Egg Production: Unlike males, who continuously produce sperm, females do not produce new eggs after birth.

This biological difference is fundamental to understanding human reproduction and the roles of different genders in the process.
