Frequent ejaculation linked to longer life, lower cancer risk, Japanese doctor says

A Japanese urologist has sparked widespread discussion by referencing a Harvard study that suggested ejaculating 21 times a month could help prevent prostate cancer. However, many questioned the feasibility of such a high frequency. Now, Dr. Kurata Mochida, a popular urologist with a significant online following, has cited multiple studies to propose a more accessible approach: consistent and slightly more frequent ejaculation is linked to a longer lifespan.

Citing a long-term study published in the *British Medical Journal*, Mochida highlighted research tracking 918 middle-aged men over a decade. The findings revealed that men who ejaculated more frequently had a 50% lower mortality rate compared to those who ejaculated less often. For instance, if 10 men in the low-frequency group died over 10 years, only 5 in the high-frequency group did.

Mochida suggests that the benefits extend beyond just cancer prevention. He posits that ejaculation triggers a cascade of positive effects in the body and brain. During ejaculation, the brain releases a potent mix of neurotransmitters: dopamine for happiness, beta-endorphins for stress relief, oxytocin for anti-aging and cell repair, and serotonin for mood stabilization and combating depression. This rare "four-in-one" neurochemical release can significantly reduce stress and enhance mental and brain health.

Furthermore, research indicates that men who maintain a regular ejaculation habit exhibit about 30% higher immunity markers than those who do not, bolstering their defense against illnesses. Another UK study following 2,500 men for four years found that men experiencing a significant decrease or interruption in ejaculation frequency faced a 1.7 times higher risk of developing serious diseases. Mochida also linked testosterone levels to longevity, noting a German study where men with low testosterone who didn't receive treatment had a 2.3 times higher mortality rate over 10 years compared to those treated.

While the initial suggestion of 21 ejaculations per month aimed at prostate cancer prevention, Mochida now advises against undue pressure, citing studies from countries like Spain. These studies suggest that ejaculating fewer than three times a month can increase health risks, including prostate cancer. Therefore, he recommends a more achievable target of 3 to 4 times per month as a beneficial frequency for maintaining prostate health and overall well-being.
