Another meta-analysis published in April 2022 shows a link between vasectomy and prostate cancer.

CONCLUSIONS: Our meta-analysis found an association between vasectomy and any, mainly localized, PCa. However, the effect estimates of the association were increasingly close to null when examining studies of robust design and high quality. On exploratory analyses including studies, which adjusted for PSA screening, the association for aggressive and/or advanced PCa diminished.

Patient summary: In this study, we found an association between vasectomy and the risk of developing localized prostate cancer without being able to determine whether the procedure leads to a higher prostate cancer inc

I found this study today that looked at zinc production in the testicles of rats after vasectomy. Zinc has been connected to infertility and testosterone production. I will admit that this paper is beyond my scope of expertise but the authors did acknowledge several other issues associated with vasectomy like Chronic pain and Prostate Cancer. They also acknowledge a lack of understanding and studies done on the changes with the testicles after the procedure. Others on on here might find this to be an interesting read.

I saw your comment in r/childfree post about a husband worried about cancer risks of sterilization. Your comment was removed, as I assume like most people, the mods and commentors don't believe prostate cancer is a risk despite the recent evidence published in Europe and Asia. It's fair to say that in the US, doctors have shut down the linkage despite inconclusive evidence at best so in some respects I can't blame people for believing it. But there seems to be a real effort among some doctors in the US to get a more definitive answer. I wish this paper used the more recent studies from Europe but at this point, I am glad to see a real interest in getting this answered for the doctors that s

I found this Finnish study published early this year. It shows similar results to the Danish and Chinese studies recently published. However, the authors seem to downplay the risk because the mortality rate is lower than expected. They also weren't sure why that would be the case but they did offer some theories. Generally, I would prefer to avoid getting cancer (regardless of the morality rates) especially with elective procedures. Kind of odd to see these two conclusion together (higher incidences of prostate cancer after vasectomy, but 50% decrease in men's risk for overall mortality).

This may hit the India market soon but there remains very limited data on it's safety. It appears the pvps is still an issue in the trials. Hopefully, this can be worked out over time.
