How often men masturbate may relate to prostate cancer risk

FCancer's new campaign points to research that men reporting 21 or more ejaculations per month had about a 19–22% lower prostate cancer risk in a long-term study, and it uses videos, a song and apps to raise awareness.

FCancer, a nonprofit cancer organization, has launched a campaign called Beat Cancer Off to raise attention to prostate health. The outreach was created with VML Health and uses playful language, a jingle, a video, a smartphone app and influencer partnerships. The campaign highlights research that associates higher ejaculation frequency with a lower risk of prostate cancer. Organizers say they designed the campaign to reach men with less clinical messaging and to encourage medical screening. Key points: - FCancer and VML Health launched the Beat Cancer Off campaign, which includes a video, song, smartphone app, influencer kits and brand partnerships. - A long-term study of 31,925 men followed for 18 years is reported to have found that men who ejaculated 21 or more times per month had a 19–22% lower risk of prostate cancer compared with men reporting 4–7 ejaculations per month. - A 2025 analysis of 29 studies involving more than 315,000 participants is reported to support a correlation between higher ejaculation frequency and lower prostate cancer risk. - The campaign cites proposed explanations such as more frequent ejaculation reducing prostatic inflammation or clearing substances, and mentions possible links to immune and stress-related factors. - Dr. Lorelei Mucci is quoted as saying frequent ejaculation is not a guarantee against prostate cancer, and the campaign is reported to encourage men to seek medical evaluations; the American Cancer Society is cited on prostate cancer being the second most common U.S. cancer and having higher rates among Black men. Summary: The campaign uses humor and cultural messaging to draw attention to studies linking higher ejaculation frequency with lower prostate cancer risk. Undetermined at this time.
