This lesson covers the role of hormones in human reproduction, including puberty and the menstrual cycle, as required by the AQA GCSE Combined Science Trilogy specification (8464). You need to know the key reproductive hormones, where they are produced, and what they do.
Puberty is the stage of development when the body becomes sexually mature — capable of reproduction. It is triggered and controlled by hormones released from the pituitary gland and the reproductive organs.
| Hormone | Produced By | Role |
|---|---|---|
| Testosterone | Testes (male) | Stimulates sperm production; causes development of male secondary sexual characteristics |
| Oestrogen | Ovaries (female) | Causes development of female secondary sexual characteristics; involved in the menstrual cycle |
