Thoughts on vasectomy causing autoimmune diseases

Me and my husband are talking about him getting a vasectomy. In August we’ll have 4 babies 5 and under so we’re DONE! I asked a “crunchy” mom group their thoughts on vasectomy and gosh I shouldn’t have…they told me that 20% of men have chronic pain post vasectomy. You're more likely to have low testosterone, higher rates of autoimmune disease and more likely to have an aggressive form of prostate cancer. They also don't work 100% of the time. They can cause mens testosterone to drop and depression.

We do want to talk to a urologist about this too but I was just wondering if a urologist told yall this before the procedure. I’m not sure where they got their “facts” I just don’t want to risk my husband in any way.
