For most women, menopause occurs naturally around the age of 49. In the lead up to menopause, the quality and quantity of eggs declines over time. Then the ovaries stop releasing eggs completely.

At this time, the ovaries also stop producing the sex hormones oestrogen and progesterone. This causes menstrual periods to end. When you clock 12 months of no periods, you’re in menopause.
