Question: 1 / 400

What happens to reproductive organs during puberty?

They shrink

They become dormant

They grow and start making sex cells

During puberty, reproductive organs undergo significant development and maturation. This is a crucial stage in human development, where the body prepares for reproduction. The correct response highlights that the reproductive organs grow in size and begin producing sex cells, which are essential for reproduction.

In males, the testes enlarge and start producing sperm, while in females, the ovaries grow and begin to release eggs through a process called ovulation. Hormonal changes triggered by the brain also stimulate these developments, leading to the onset of secondary sexual characteristics such as breast development in females and increased muscle mass in males.

This growth and functional activation of the reproductive system mark the transition from childhood to adulthood, enabling the potential for reproduction in the future.
