Many of the claims go well beyond or even directly against the scientific evidence about what scientists call “T.”
Myth No. 1: Testosterone is the male sex hormone.
T isn’t just a male hormone: It’s also the most abundant biologically active steroid hormone in women’s bodies — crucial for female development and well-being. It helps support ovulation, for instance. And T isn’t just a sex hormone, either. In men and women, receptors for the hormone are found in almost all tissues, and it contributes to lean body mass, bone health, cognitive function and mood, among other attributes.
Myth No. 3: Testosterone supercharges your love life.
Ads for testosterone boosters promise “vigor & vitality,” increased “stamina” and “improved confidence in the bedroom,” while tabloid publications make tantalizingly specific pronouncements such as: “The higher the testosterone level, the greater the amount of sexual activity.”
Unfortunately for marketers and would-be Lotharios, “studies of men’s testosterone and sexual behavior suggest either weak or null relationships,” as one review of the scholarly literature put it in 2017. A certain (relatively low) level of testosterone is necessary for optimal sexual functioning, but above that threshold, more T doesn’t make much difference, for men or women.
