# How common is infertility in older women and what conditions are linked to it?

Permanent infertility affects 2.6% of women aged 40-42, and subfertility affects 7.7%. Premenstrual tension is more common in infertile women (almost 40%) than in fertile women (29.4%).

 Moderate study design

4034 women aged 40-42 in Norway (78% response rate from 5139 invited)

## What they did

Cross-sectional health screening of 4034 women out of 5139 invited (78% response rate) aged 40-42 in one Norwegian county. Included clinical screening and questionnaires about reproductive history and infertility.

## What they found

Permanent primary infertility in 2.6%, subfertility in 7.7%. Infertile women more often had pelvic inflammatory disease (32% versus 11%), amenorrhea (13% versus 3.3%), and premenstrual tension (almost 40% versus 29.4%) compared to fertile women.

## What it means for you

Premenstrual tension is more common in women who cannot get pregnant, suggesting a link. However, we don't know if one causes the other or if both are caused by something else. The study included a large population from one country but cannot prove cause and effect.
