Testosterone: Do We All Need a Boost?

Science Vs examines whether the growing enthusiasm for testosterone supplementation is justified: can raising testosterone levels make people stronger, increase sexual desire or improve energy, and what risks might accompany those changes? The episode features endocrinologists Prof. Shalender Bhasin and Prof. Richard Auchus, alongside social psychologist Dr. Justin Carré. Wendy Zukerman is credited as executive producer. The show notes frame the discussion as an investigation of popular claims, not an endorsement of testosterone use.

The episode separates the broad promise of a testosterone “boost” into distinct questions. It examines size and strength at 02:59, the possibility of “’roid rage” at 09:25, sexual desire at 18:04 and energy at 25:48, before addressing risks at 27:51. That structure matters analytically: a claim about muscle growth does not, by itself, establish a benefit for mood, libido or everyday vitality. The combination of endocrinology and social psychology expertise brings both physiological effects and behavioral questions into the discussion. However, the notes provide no study results, effect sizes or expert conclusions, so they do not establish which advertised benefits hold up.

The immediate context is the promotion of testosterone by influencers, celebrities and government officials, including messages encouraging people to monitor their levels and supplement if they are low. Against those promises, the episode raises infertility, aggression and other possible risks, then turns at 31:49 to the broader question of why testosterone attracts such attention. The key unresolved issue in the supplied notes is how the guests distinguish situations in which testosterone may be appropriate from generalized enhancement claims. The notes also leave unanswered how benefits and risks vary by individual circumstances, treatment approach or baseline testosterone level.
