UCL scientists find no evidence that testosterone eases menopause 'brain fog' despite social media being flooded with claims it works

A UCL review of five studies covering 244 post-menopausal women found no significant improvement in cognitive function among those given testosterone, challenging a trend driven heavily by social media influencers. Researchers examined whether the hormone boosted learning, memory and concentration over periods ranging from four to 26 weeks, finding the evidence insufficient to establish any clear benefit.

Women are reportedly posing as men online to obtain testosterone prescriptions, so strong is social media pressure around the treatment.

Professor Aimee Spector said anecdotal evidence may exist for perimenopausal women, but that group was absent from all five trials reviewed.

UCL noted testosterone prescriptions have already risen sharply in the UK, reflecting demand the new findings now directly challenge.
