2. Puberty is a period from which our body changes from a child to an adult. This happens because our body wants to prepare itself to be able to have a baby.

3. WHY DOES IT HAPPEN? Puberty starts when extra amounts of chemicals called hormones start to be produced in the body. The body produces the sex hormones estrogen, progestogen and testosterone which are responsible for many different changes in the body. The brain and pituitary gland release the sex hormones that regulate the reproductive organs.

4. The reason boys have a reproductive system is because it provides the sperm needed to fertilize a female’s egg, which can then develop into a baby . During puberty the levels of the hormone testosterone in your body begin to rise. This causes the penis and testicles to get bigger and the testicles to produce sperm. The testicles cannot make sperm before puberty. Sperm look like tadpoles, with what appear to be a head and a tail .

5. MALE REPRODUCTIVE SYSTEM
