Body 101
Know your body, inside and out. Clear, simple facts about the male and female reproductive systems.
The male reproductive system includes the testes, the tubes that carry sperm, the glands that make semen, and the penis.
From puberty, the testes make sperm and the hormone testosterone, which brings changes like a deeper voice and body hair.
Knowing how your body works helps you look after it. Watch to learn the basics.
Yowun Piyasa (Youth Hub) is for you to get to know about your body, health and relationships.
