# How do estradiol and progesterone levels relate to PMS symptoms across the menstrual cycle?

Progesterone levels are linked to PMS symptoms and appear 5 to 7 days before symptoms develop. This preliminary finding suggests progesterone may be required for PMS symptoms to occur.

 Early or limited evidence

10 women with confirmed PMS and 8 asymptomatic women

## What they did

10 women with PMS and 8 asymptomatic women had daily measurements of estradiol and progesterone plus daily symptom reports during the same menstrual cycle.

## What they found

Progesterone was significantly and positively correlated with PMS symptoms throughout the entire cycle and preceded symptoms by 5 to 7 days. Both hormones were consistently but not significantly higher in PMS women overall.

## What it means for you

Progesterone may trigger PMS symptoms days before women notice them. Limitation: very small study of 10 women with PMS and preliminary findings that require confirmation with larger research.
