# Does having worse premenstrual symptoms mean you are more likely to get pregnant?

Women with more severe premenstrual symptoms were more likely to get pregnant during infertility treatment, with pregnancy rates rising from 12.7% to 35.0% across severity groups. However, the reason is unclear because hormone levels were not measured.

 Moderate study design

185 women undergoing Korean medicine infertility treatment

## What they did

Cohort study of 185 women undergoing a four-month Korean medicine infertility programme. Researchers measured baseline premenstrual symptom severity, then tracked pregnancy rates. Models were adjusted for age, BMI, infertility duration, menstrual cycle irregularity, and prior fertility treatments.

## What they found

Higher baseline premenstrual symptom severity was associated with pregnancy. Pregnancy rates increased from 12.7% in the lowest psychological symptom group to 35.0% in the highest. Odds ratios per standard deviation were 1.66 for psychological symptoms, 1.51 for physical symptoms, and 1.43 for other symptoms.

## What it means for you

Surprisingly, women with more severe premenstrual symptoms were more likely to get pregnant. The authors suggest symptom severity may reflect stronger ovulation and luteal-phase activity, but this remains unconfirmed because ovulation and progesterone were not measured. The study was in a specific treatment setting (Korean medicine), which may limit generalizability.
