Surprisingly, no consensus yet exists as to the answer. However, a wide gap yawns between popular lore and the views of most reproductive health experts. Intercourse (partnered intimacy) offers benefits. Yet no convincing evidence supports prioritizing orgasm over intercourse.

For example, this review  examined 16 studies on ejaculation frequency: Evidence for Masturbation and Prostate Cancer Risk: Do We Have a Verdict?  The authors concluded that no individual study variables specifically caused direct outcomes.

Fewer than half (seven) of the studies reported protective associations (reduced rates of cancer). Three of these reported contradictory findings in their study populations related to controlled variables (e.g., age range). There was some agreement across studies that later in life ejaculation frequency (at various points during one’s life) correlated with better prostate health.

However, as one research team noted, no one yet knows which specific ejaculation-related factors might offer benefits. Penetrative intercourse, masturbation, pre-ejaculation arousal, nocturnal emission, or factors still unknown?

There’s a potential confound too. Healthier men may ejaculate more (at least with partners), so ejaculation frequency should correlate with better health.

In any case, the prostate is a gland, not a muscle. Glands secrete fluids all on their own (e.g., wet dreams), and do not require physical intervention. If a man cares to engage in Synergy, his body can meet his ejaculation needs (if any) without intervention.

What do the experts say?

Researchers have investigated various factors related to prostate cancer (obesity, occupational exposures, STIs, circumcision, vasectomy, multiple sexual partners, and, of course, sexual activity). Yet the only recognized risk factors for prostate cancer to date are older age, race and ethnicity, and a family history of the disease.

Healthcare professionals currently recommend the following protective measures: prostate-specific antigen screening, nutrition and dietary choices, physical activity, and other lifestyle and behavior modifications. In fact, a 2008 study on men with prostate cancer, reported in a major medical journal, showed that support-group attendance, stress-management techniques, moderate exercise, and improved diet could actually “turn off” many disease-promoting genes (including those associated with cancer, heart disease, and inflammation). At the same time, protective, disease-preventing genes were up-regulated or “turned on.”
