According to the sources, the failure rate for vasectomies is very low, with only one to two in 1,000 men experiencing a failed vasectomy. However, in rare cases, a vasectomy can fail if the doctor misses the vas deferens during the procedure, and the tube can regrow, though this is very uncommon. Another possible cause of failure is having sex too soon after the surgery, without using an alternate form of birth control.

I typically dont use pain killers before or after vasectomy. Just local anesthesia.

One study conducted by researchers at Northwestern University found that men with PPA were more likely to have undergone vasectomy than cognitively normal men of the same age, with 40% of men with PPA having had a vasectomy compared to 16% of others. However, it's important to note that this study only showed a correlation and not causation. Further research is needed to determine whether there is a causal relationship between vasectomy and PPA or other forms of dementia. It's also worth mentioning that the vast majority of men who have undergone a vasectomy do not experience any negative effects on their cognitive abilities.

This is because sperm can remain in the semen and the reproductive system for several months following the procedure, and it can take up to 90 days or more for all the remaining sperm to clear out despite several ejaculations.

the success of a vasectomy reversal can vary based on various factors such as the experience of the surgeon, the technique used, and the specific circumstances of the patient. However, with proper surgical techniques, the success rate can be high. It is best to consult with a qualified medical professional for an individual assessment of your specific case. https://pubmed.ncbi.nlm.nih.gov/21716894/
