The prevalence of men’s health conditions increases with advancing age. Evidence mainly sourced from populations in the United States suggests that about 40% of men are affected by erectile-dysfunction at age 40, which increases to roughly 70% by age 70.[1] About 50% of men over age 50 show evidence of benign-prostatic-hyperplasia, which increases to more than 80% in men over 70.[2] About 99% of all prostate cancers occur in men over age 50,[3] and testosterone levels decrease by as much as 0.4–2% annually after age 40.[4]
