Menopause

Early menopause and premature ovarian insufficiency (POI)

Sometimes menopause happens earlier than expected. Premature ovarian insufficiency (POI) refers to reduced ovarian function before the age of 40; early menopause refers to menopause between about 40 and 45.

This can be unexpected and emotional news. This page explains what these terms mean and why ongoing support and follow-up matter, sensitively, and without alarm.

Key points

  • POI is when the ovaries reduce function before age 40.
  • Early menopause happens between about 40 and 45.
  • It can affect periods, symptoms, fertility and long-term health.
  • Support and follow-up are important, and help is available.

What POI and early menopause mean

In POI, the ovaries stop working as expected before 40. This isn't always permanent or complete, and it's different from typical menopause. Early menopause is menopause occurring a little earlier than average. A specialist can explain which situation applies to you.

Why follow-up matters

Because oestrogen has wide effects on the body, earlier menopause can have implications for symptoms, bone and heart health, and fertility. For this reason, ongoing review and support are important, and there are options to help, discussed individually.

Fertility and emotional support

POI can affect fertility, though outcomes vary and pregnancy is sometimes still possible. This can be a difficult adjustment, and emotional support is an important part of care. You don't have to navigate it alone.

When to see a specialist

If you have menopausal symptoms or periods stopping before 40 to 45, it's worth seeking review. A specialist can assess what's happening, arrange relevant tests, and talk through support and options.
