Key Takeaways

  • Testosterone levels: Abstaining from ejaculation for twenty days does not increase baseline testosterone levels. The only measurable testosterone bump occurs immediately after orgasm for both men and women, lasting briefly before returning to normal baseline levels.
  • Athletic performance: Sexual activity does not impair athletic performance unless it occurs within two hours of competition. Studies measuring grip strength, cycling speed, and weightlifting found no performance differences between men who abstained versus those who had sex the night before.
  • Sperm quality optimization: For conception, abstain two to five days before the fertile window to balance sperm count and quality. Beyond five days, DNA damage accumulates in sperm stored in the epididymis, reducing motility and viability despite higher volume.
  • Psychological effects: Online NoFap communities correlate with increased shame and worthlessness after ejaculation, unlike typical support groups. The guilt-based messaging creates stress around natural urges, though individual abstinence without community involvement poses no physiological harm.

What It Covers

Science Vs examines semen retention claims with urologist Justin Dubin and fertility specialist Brent Hansen, investigating whether abstaining from ejaculation increases testosterone, improves athletic performance, enhances sperm quality, or poses health risks.

Notable Moment

Researchers discovered sperm volume increases approximately twelve percent per day of abstinence up to four days, but DNA damage simultaneously accumulates in stored sperm, making frequent ejaculation beneficial for sperm health despite producing lower volumes per sample.

Episode Transcript

Hi. I'm Wendy Zuckerman. You're listening to Science Versus. Today on the show, we're pitting facts against fapping. That's right. With No Nut November just around the corner, we thought it was a great time to ask, what are the benefits of saving your seed and not ejaculating? And this is something that former tax accountant and current comedian and also my friend, Soren Jayamana, has been curious about for a little while now. Hi, Soren. Hello. How do you feel about, being introduced as a sort of semen retention curious? Oh, I thought you were gonna say as a former tax accountant. Yeah. That's correct. Now for for those who are, uninitiated, semen retention, I've now become very familiar with this term, but it it basically means you you retain your semen. You keep it in. You don't release it. Yes. When did you start getting curious about this semen retention? Well, yes. I guess, more recently as as I've sort of delved into, like, meditation and more kinda yoga, well, I would say tantra type stuff, which is, like, Hindu kind of, I guess, philosophy Uh-huh. And tantra in the West, we think of it as very sex oriented, but it's actually just kinda like ritualistic ways to to build meditation and practice that kind of stuff. A lot of those Eastern philosophies are based on energy and, like, is there are you leaking energy? Uh-huh. Is ejaculating leaking energy? Yeah. Yeah. And I guess that at a very high level, this is the stuff that you make people with. Mhmm. So it's like the creative force of life. Yes. And then if you're just kind of wasting it Giving it to a sock. Yeah. Giving it to a sock. It's funny because it is true that for thousands of years, men in particular have been conflicted over whether to fap or not to fap. Yeah. Right. And for some in the ancient world, semen was seen as this powerful thing. Sometimes this great powerful thing that could do super impressive stuff, like apparently the Sumerian god Enki came, and that's how we got the Tigris and Euphrates Rivers. Yeah, okay. And then, because the but then on the other hand, it's like this conflict that we've had for so long, because then you've got Hippocrates and Taoist mystical practitioners, and then the eighteenth century, you've got philosophers, and the nineteenth century, you've got American doctors, all on team cockblock, saying that things like masturbation and losing your semen weaken a man's body and brain. It's it's it is quite funny, actually, throughout history how much it's, like, all these big thinkers, and this is it's occupying a lot of space. Yeah. And a lot of these ideas are still out there Yeah. When you go online, and it was very interesting that there are just loads of guys out there. Loads is probably the wrong word. When you tell me what you're telling me. Or is it …
