Scientific evidence does not show that frequent ejaculation causes major physical harm and may be associated with a lower long‑term risk of prostate cancer: large prospective analyses found men report...
Research finds that sexual activity and orgasm remain possible for many men aged 80 and over, but both the frequency of partnered sex and rates of orgasm decline sharply compared with younger older ad...
A small but growing body of human epidemiology, tissue‑level gene‑expression work, and mechanistic reviews test the "prostate stagnation" idea—that ejaculations might flush xenobiotics or carcinogenic...
Large prospective cohort studies and several case–control analyses report an inverse association between higher ejaculation frequency in adulthood and subsequent prostate cancer risk—especially for ej...
Evidence is mixed but leans toward a modest protective association between higher ejaculation frequency in adulthood and lower overall prostate cancer incidence in large prospective cohorts, while som...
Large prospective analyses find a modest inverse association between higher ejaculation frequency and subsequent prostate cancer diagnosis, with signals that the protective association appears across ...
The strongest prospective evidence links higher ejaculation frequency in adulthood to a lower overall prostate cancer incidence, most notably from the long-running Health Professionals Follow‑up Study...
A body of large observational studies finds that higher ejaculation frequency is associated with a lower subsequent risk of being diagnosed with prostate cancer, including in middle-aged and older men...
Lifestyle changes such as exercise and diet reliably improve and cardiovascular health in older men, but the scientific literature does not support a direct, meaningful change in penile length from li...
