Sex Drive: The Dirrrrrrty Science

Testosterone Myths

The episode kicks off with a deep dive into the myths surrounding testosterone and its perceived role in sex drive. Wendy Zukerman and Professor Caroline Pukall discuss how testosterone is often marketed as a magic bullet for boosting libido, despite scientific evidence suggesting otherwise. Caroline explains that while testosterone supplements might help men with clinically low levels, they don't significantly impact those with normal levels.

The science says that for most of us, getting a little more testosterone won't affect our gurr.

For women, the situation is similar, with testosterone rarely being the solution unless specific conditions like menopause are involved 1.

   

Kisspeptin Research

The exploration of kisspeptin, a relatively new hormone, reveals its potential impact on human libido. Professor Waljit Dhilo shares insights from his research, highlighting how kisspeptin might influence sexual arousal by affecting brain regions linked to inhibition and arousal. In a study involving both men and women, kisspeptin appeared to enhance arousal levels, although participants didn't report feeling significantly different.

You've got a brake and you've got an accelerator. So effectively, you're taking off that brake.

--- Professor Waljit Dhilo

This research suggests that while kisspeptin shows promise, it isn't the definitive solution to boosting libido 2.
