We posted a urologist’s advice on prolonged chastity and whether or not prostate milking is necessary a while ago.
A 2004 study found that the more often men ejaculated, the less likely they were to get cancer, while some things should be avoided (learn about the specific mesothelioma-related cause at https://mesotheliomaexplained.com/mesothelioma-lawyers/ as an example of such). The sample of this study (with many participants under 50 years old) made it hard to gauge the reliability of the results.
IFLScience! reports that a follow-up study by Harvard T.H. Chan School of Public Health has extended the study and recently presented the results of their research.
Men who ejaculated more than 21 times a month were significantly less likely to develop prostate cancer than those who did so 4-7 times. For those with a (adult) lifetime average above 21 times a month, cancer risk was reduced by a third.
The bad news is that regular enjoyment doesn’t have a measurable effect on the most deadly forms of prostate cancer, instead reducing the “organ-confined and low-grade” cancer risks.
If you’re good at understanding statistics, the actual numbers are here.
