Ferriss Discloses TMS Treatment Caused Two Week Inability to Ejaculate
"After my first effective TMS treatment, the first one that worked, I could not ejaculate for like 2 weeks, and I fucking lost it. The doctor's like, yeah, we've never seen that before. I was like, oh, fantastic."
About this episode
In this episode of Modern Wisdom, host Chris Williamson is joined by author and investor Tim Ferriss along with entrepreneur Nirav Tolia and recurring guest George Mack for a wide-ranging three-hour conversation covering neuromodulation, AI's societal impact, the meaning crisis, and cultural differences between the US and UK. The most newsworthy revelation came from Ferriss, who disclosed dramatic anxiety relief using transcranial magnetic stimulation (TMS) combined with neuroplasticity agents, reducing his generalized anxiety from 8-9 out of 10 to near-zero for months at a time. He revealed investing in AMPA Health, a neuromodulation startup, and said brain stimulation has replaced psychedelics as his primary mental health intervention over the past three years. Ferriss also disclosed an embarrassing and previously unreported side effect from his first successful TMS treatment: a two-week inability to ejaculate that his doctor had never witnessed before. Williamson contributed data showing the UK arrested over 12,000 people for social media posts in 2023—nearly double second-place Belarus and far exceeding Russia and China—sparking debate about Western civil liberties. Tolia revealed that many San Francisco AI researchers privately believe fundamental problems are solved and AGI will arrive rapidly. The conversation expanded into the future of user interfaces, the iPhone's dominance, looksmaxing via AI, and whether secular society can generate meaning without religion. Williamson also detailed his own stellate ganglion block procedure, which increased his HRV by 30% overnight. The episode blended personal experimentation, insider tech commentary, and philosophical inquiry into what happens when technology removes scarcity.
