Media personality Daddy Freeze’s claim that men must ejaculate 21 times a month to lower prostate cancer risk has sparked debate, though experts say there is no scientific consensus.
A viral comment by Nigerian media personality Daddy Freeze claiming that men must ejaculate at least 21 times a month to reduce the risk of prostate cancer has generated widespread discussion and confusion online. While the topic has been studied, experts emphasise there is no definitive rule, and understanding the risk factors for prostate cancer remains critical given its prevalence, with about one in eight men diagnosed at some point in their lives.
The “21 times” figure originates from a 2004 study of 29,000 men over eight years, which suggested that men who ejaculated 21 or more times per month had a 31% lower risk of prostate cancer compared with those who ejaculated four to seven times per month. However, other studies before and after 2004 have produced inconsistent results, particularly when age is considered. A 2017 study found only a small and uncertain link: men in their 30s who ejaculated more frequently might have a slightly lower risk of aggressive prostate cancer, but no clear connection was observed for men in their 20s, and evidence for men in their 40s was weak.
Another study from 2009 highlighted that sexual activity may affect prostate cancer risk differently depending on age. For younger men in their 20s and 30s, more sexual activity, particularly masturbation, was linked to a slightly higher risk, while men in their 50s appeared to benefit slightly from frequent sexual activity, showing a modestly lower risk. Experts caution that the relationship between ejaculation frequency and prostate cancer is complex, and oversimplified conclusions like the “21 times a month” claim should not be taken as medical advice.
