In fact, it’s the exact opposite: there’s overwhelming evidence that getting a cut can dramatically improve the sex lives of men and their partners.

Vasectomies, which have a 99% success rate, are considered the most effective form of contraception. And yet, it’s estimated that only one in 10 men in the US undergo the procedure, which is about half the rate in the UK and Canada, with some studies suggesting that number is also falling.

So what’s stopping American men who don’t want to get their partner pregnant from getting a cut? Some researchers think concerns about erectile dysfunction might be to blame.

“Many patients are concerned about the association between vasectomy and sexual function and fear that the quality of their sex life may be affected after surgery,” the researchers wrote in a meta-analysis of 20 studies on the topic in 2020. The thing is, they found pretty much the exact opposite: Several studies confirmed that men who had vasectomies had “significantly improved erectile function, orgasms, and sexual satisfaction and felt more secure and more confident in their sex life after surgery”.

Female partners have also reported improvements with their recently cut men, especially in terms of orgasm, libido and lubrication. The researchers also found evidence that men who had a vasectomy slept more often than men without a vasectomy. Or rather, “Men who had a vasectomy had more sexual contact per month than men who had not had a vasectomy.”

Of course, that’s not to say there’s no risk of complications, but the researchers note that those risks are relatively small — about one to two percent. And they usually involve temporary infection or scrotal pain, not erectile dysfunction. “There is basically no concern about ED cases getting worse later on, because erections and sperm creation are two separate mechanisms,” explains Darshan Patela urologist at the University of California, San Diego School of Medicine who was not associated with the meta-analysis.

In fact, for men who have sexual difficulties after a vasectomy, performance anxiety may be a more likely culprit than physiological issues. Some studies have shown that vasectomies can cause increased anxiety or depression, but researchers believe this is mainly due to a lack of education about the safety of the procedure, as well as insufficient access to mental health counseling. (For his part, Patel recommends therapy for men struggling sexually after the cut.)

Because again, physically, everything will be fine – if anything, better than ever.
