- The testes are always making new sperm.
Key Stage 4

- During ejaculation the sperm cells leave the testes via the sperm duct.
About the Testes as Endocrine Glands
- The testes secrete a hormone called testosterone.
- Testosterone causes the expression of male characteristics during puberty including muscle growth, growth of facial hair and the deepening of the voice.
