A recent UK Independent article Masturbation can be good for the over-50s, reported on a study published in the British Journal of Urology International that showed a link between masturbation and increased risk of prostate cancer. The study examined the sexual habits of men diagnosed with prostate cancer under the age of 60 against a control group. Younger men engaging in sexual activity (sex and masturbation) at least 20 times a month appear to be at an increase risk of prostate cancer. Interestingly, the risk decreased in men over 50 who engaged in sexual activity at least 10 times a month.
The researchers have no explanation as to why masturbation, as opposed to sexual intercourse, is a marker for increased risk of prostate cancer. Seems like men of any age should just relax and enjoy themselves…by themselves or otherwise.
