Please research the risks involved in a vasectomy. I personally would not recommend it to any couple, nor any other surgical operation for contraception.
1 in 10 men develop long term testicular pain - your GP will not tell you about this, or indeed quote 1 in 1000. It's a lie.
Worst decision of my life.
Been in constant pain now for nearly a year and a half.
I've had additional surgery where my testicle was taken out of my scrotum, the epididymis cut off, and then stitched back in. Has cured some pain, but I am now in additional pain from the latest surgery, plus my non-operated testicle is still sore.
It hasn't cured my Post Vasectomy Pain Syndrome. I wake in pain every day. It's ruined our sex life completely.
Can't even have them cut off as the pain will remain.
Please research PVPS before even thinking about it. It's very common. The surgery itself is simple, but the after effects are nasty.
We both did not want any more kids, we neither had any of the 'what if you leave/die' intentions, but the effect of the surgery has been horrible. I would never recommend it given the high risk of post surgery complications that can't be cured.
