In the study, 96 postmenopausal women recruited from the community were randomly allocated to receive a testosterone gel or a visually identical placebo gel to be applied to the skin. Participants underwent a comprehensive series of cognitive tests at the beginning of the study and 26 weeks later.
All women performed in the normal range for their age at the beginning of the trial. There was a statistically significant and clinically meaningful improvement in verbal learning and memory amongst the women using the testosterone gel after 26 weeks.
Professor Davis said the results indicated that testosterone played an important role in women’s health.
“Much of the research on testosterone in women to date has focused on sexual function. But testosterone has widespread effects in women, including, it appears, significant favourable effects on verbal learning and memory,” Professor Davis said."
