Study, 1980

Do women commit violent crimes more often at certain times in the menstrual cycle?

Yes. Among 50 women charged with violent crimes, 44% committed their offense during the paramenstrual phase (just before or after the period), with very few crimes during ovulation and the post-ovulatory phase.

Early or limited evidence 50 women charged with violent crimes.

What they did

Researchers examined records of 50 women charged with violent crimes and determined when in their menstrual cycle each crime occurred.

What they found

44% of crimes happened during the paramenstrual phase (just before or after the period). Very few crimes happened during the ovulatory and post-ovulatory phases. The timing of crimes was not related to whether women reported having PMS symptoms.

What it means for you

This study found a pattern of more crimes during certain cycle phases in women who committed violent crimes. The pattern was not explained by women's self-reported PMS symptoms. This is a descriptive study of criminal records, not a controlled trial.
