Does Polygamy Offer Protection Against Prostate Cancer? Data from regions with significant polygamy, such as the Middle East and North Africa, demonstrate lower prostate cancer incidence. Research suggests regular ejaculation may lower prostate cancer risk. It is essential to distinguish between polygamy and promiscuity, as the latter elevates cancer risk due to STIs. Fact-checking reveals substantial global disparities in prostate cancer rates: 27% for Black males, 12% for White males, and 7% for Asian males in the MENA region. Further investigation is necessary to substantiate the link between polygamy and reduced prostate cancer risk.
