You should definitely read up on it more before proceeding with the so-called procedure. I’m about 3.5 months out and I’ve basically had the symptoms of chronic prostatitis ever since (pain/burning/heaviness in scrotum and near the prostate). Go on Google Scholar and read up on post-vasectomy pain syndrome symptoms and rates.
Also, read up on chronic post-surgery pain. By referring to this as a procedure and not a surgery, I think the urologists (unwittingly?) cause those of us going in to discount the risk. Here are a couple interesting publications on the more general topic of chronic post-surgery pain and whether the risks outweigh the rewards for an unnecessary surgery:
https://bjanaesthesia.org/article/S0007-0912(17)34271-X/pdf (“Awareness of the risk of chronic pain is particularly relevant when patients wish to have surgery for reasons other than illness or disability, for example, male and female sterilization and some cosmetic surgery operations, which may be performed for aesthetic rather than medical reasons. Chronic pain after vasectomy has been the subject of several studies. These show an incidence of around 15%. . . It is disappointing then to find in a recent publication on sterilization the statement: ‘Whether a postvasectomy pain syndrome exists remains controversial’.”).
https://bjanaesthesia.org/article/S0007-0912(17)36346-8/pdf (Vasectomy is the second most common operation performed on men worldwide. It is performed for social reasons rather than because of illness and men having vasectomies are pain-free before the procedure. It is distressing, therefore, to and that chronic testicular pain occurs in between 5% and 33% of patients.").
