🔬 Key Reproductive Hormones
| Hormone | Made by | Function |
|---|---|---|
| FSH | Pituitary gland | Causes eggs to mature in ovary; stimulates oestrogen production |
| LH | Pituitary gland | Triggers ovulation (egg release) |
| Oestrogen | Ovaries | Repairs uterus lining; inhibits FSH; stimulates LH surge |
| Progesterone | Ovaries (corpus luteum) | Maintains uterus lining; inhibits FSH and LH |

What is contraception?
Contraception is any method used to prevent pregnancy by stopping fertilisation or implantation of an egg. Methods can be hormonal, barrier, or other approaches.
How does the contraceptive pill work?
The pill contains synthetic oestrogen and/or progesterone. These keep hormone levels high, which inhibits FSH release from the pituitary — preventing egg maturation and ovulation.
