🔬 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

Quick Recall Flashcards

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.
