Semen Retention: Should You Stop Ejaculating?

Key Takeaways Copied to clipboard!

• Claims that semen retention boosts testosterone, mood, or athletic performance are largely unsupported by current scientific evidence, with studies showing no significant testosterone increase from abstinence.  Copied to clipboard!
• While abstaining from ejaculation for a short period (up to four days) increases semen volume, prolonged abstinence (beyond five days) may lead to increased sperm DNA damage and lower sperm motility, which is detrimental for fertility.  Copied to clipboard!
• The perceived psychological benefits of semen retention, such as increased self-control or happiness, are likely due to the discipline involved rather than direct physiological changes caused by avoiding ejaculation, and the associated online communities can foster negative emotions like shame.  Copied to clipboard!

• Key Takeaway: Historically, views on male ejaculation have conflicted, with ancient Sumerian beliefs viewing it as powerful, while figures like Hippocrates and 18th/19th-century doctors warned against it as weakening.
• Summary: Throughout history, men have been conflicted over ejaculation, with ancient cultures sometimes viewing semen as a powerful creative force. Conversely, historical figures like Hippocrates and 19th-century doctors believed that losing semen, including through masturbation, weakened the body and brain.

Online Claims and Expert Investigation

• Key Takeaway: Semen retention is an overwhelmingly popular topic on social media, yet medical experts specializing in men’s health were initially unaware of the term, suggesting claims lack scientific backing.
• Summary: A urologist noted that semen retention claims on social media surpassed other men’s health topics in popularity, garnering over one billion views. However, experienced specialists in the field had never heard of the concept, indicating that the widespread claims are largely unsubstantiated by medical professionals. The investigation aims to fact-check these popular online assertions.

Testosterone and Mood Claims Debunked

• Key Takeaway: Abstaining from ejaculation for 20 days does not increase baseline testosterone levels; the only observed testosterone bump occurred immediately following orgasm.
• Summary: A study involving 20 days of abstinence showed that men experienced increased arousal and more intense orgasms upon resumption, but their baseline testosterone levels remained unchanged. The only measured testosterone increase happened after ejaculation on day 21, contradicting the claim that retention boosts this hormone. Furthermore, claimed benefits like glowing skin and thicker hair contradict known physiological effects of high testosterone, which often cause acne and hair thinning.

Impact on Athletic Performance

• Key Takeaway: Sexual activity or abstinence the night before athletic events generally does not impact performance, though exertion within two hours of an event may cause temporary fatigue.
• Summary: The belief that athletes should abstain from sex for peak performance, exemplified by historical coaching decisions, is not supported by most research, which shows no impact on lifting or cycling ability. The only noted negative effect occurs if sexual activity happens within two hours of exertion, potentially causing temporary fatigue due to physical strain and elevated heart rate during recovery.

Sperm Quality and Fertility Window

(00:25:50)

• Key Takeaway: For fertility, semen retention beyond five days is counterproductive, as it increases sperm DNA damage while only short-term abstinence (2-5 days) optimizes both sperm quantity and quality.
• Summary: While abstinence increases semen volume and sperm count (volume increases by about 12% per day up to four days), sperm motility (swimming ability) decreases with longer abstinence periods. Sperm are stored in the epididymis after maturation, where they can accumulate DNA damage if not ejaculated. For couples trying to conceive naturally, the optimal abstinence period before a partner’s ovulation is two to five days.

Risks of Prolonged Retention

(00:36:03)

• Key Takeaway: The primary risk of semen retention is psychological, stemming from online communities that promote guilt and shame around ejaculation, which studies link to increased feelings of worthlessness.
• Summary: Medically, not ejaculating is generally not harmful, though some research suggests frequent ejaculation might lower prostate cancer risk by clearing the prostate. The greater danger identified by experts is the psychological toll from online ‘No Fap’ communities, which can induce guilt, stress, and even suicidal thoughts upon relapse. These forums are noted for fostering negative ideologies, unlike typical support groups.
