Ovum

The female gamete, which is larger than sperm, non-motile, and produced in smaller quantities in the ovaries.

Puberty

The period of sexual maturation during which the production of germ cells begins and secondary sexual characteristics develop.

Testes

The primary male reproductive organs responsible for sperm production and hormone secretion.

Vas Deferens
