Menstruation ‘does not affect cognitive ability’

A new study has shown that the menstrual cycle and levels of oestrogen, progesterone and testosterone in the system have no impact on a woman’s working memory, cognitive bias ability to pay attention to two things at once.

The study, conducted by the Medical School Hannover, Germany, and University Hospital Zürich, Switzerland, found that while some hormones were associated with changes across one cycle in some of the women taking part, these effects didn't repeat in the following cycle.

Overall, none of the hormones the team studied had any replicable, consistent effect on study participants' cognition.

Professor Brigitte Leeners, of University Hospital Zürich, said she deals with many women who “have the impression that the menstrual cycle influences their well-being and cognitive performance”.

The researchers recruited 68 women to undergo detailed monitoring to investigate changes in three selected cognitive processes at different stages in the menstrual cycle. The team looked for differences in performance between individuals and changes in individuals' performance over time, and found none.ADNFCR-2094-ID-801837516-ADNFCR
