If You Want To Avoid Prostate Cancer You Should F*ck Your Brains Out

But, err, only with women. That’s real science too: the more female sexual partners you have over a lifetime the lower your risk of getting prostate cancer. And the more male sexual partners you have over a lifetime then the higher the risks of prostate cancer. That’s an effect that has actually been observed and there’s also a couple of convincing stories about why that should be:

Association between sexual activity and prostate cancer risk was examined.
•Having had >20 female sexual partners associated with decreased prostate cancer risk.
•Having had >20 male sexual partners were suggestive of greater prostate cancer risk.
•Self-identification as a homosexual was suggestive of greater prostate cancer risk.
•No association found between sexually transmitted infections and prostate cancer.

Don’t forget that just having some data isn’t enough: torture the data for long enough and you can find patterns in absolutely everything. It’s only when there’s some theory theory about what’s going on that we can start to take it all seriously.

An the basic theory about more female sexual partners is as follows: the prostate actually produces the seminal fluid which is part of the ejaculate. More sex more often means this gets flushed out more often and that’s why they think that the cancer risk declines.

But, of course, that isn’t all. for presumably the same effect could be gained simply by having lots more sex with just the one person, rather than having many partners. The response to that being, well, yes, but that ain’t the way that relationships work as anyone who has ever had more than one of them will attest. The early phases of a new relationship are going to involve a great deal more rumpy pumpy than the later stages of one: meaning that someone who has had a larger series of new relationships almost certainly will have had more rumpy in total.

As to the rise in cancer from the number of male lovers this is explained in the paper simply by the mechanics of anal sex.
