What is PMOS? The condition formerly known as PCOS — explained

In 2026, the global medical community officially renamed PCOS to PMOS. Here's what changed, why it matters, and what it means for the women living with it — and the people who love them.

PMDD: What her partner needs to know

This is not PMS. PMDD is a serious, clinically recognised condition that affects millions of women — and the people who love them often bear witness to its worst moments without understanding what they're seeing.

Endometriosis: What her partner needs to know

Endometriosis affects 1.5 million women in the UK. The average wait for a diagnosis is almost nine years. The research shows it affects the people beside those women just as profoundly.

Heavy menstrual bleeding: What her partner needs to know

HMB is the most common reason for gynaecology referral in the UK — and one of the most routinely minimised. Its most overlooked consequence is iron deficiency anaemia, which causes fatigue that persists all month, not just during her period.

Perimenopause: What her partner needs to know

Perimenopause can begin in a woman's early 40s and last for a decade. 77% of women say their partners don't understand what's happening. This guide is an attempt to close that gap.

Menopause: What her partner needs to know

Menopause is not a brief inconvenience. A 2026 study found that spousal support is a direct predictor of quality of life for postmenopausal women. Understanding what is happening is the most useful thing a partner can offer.
