Please explain what are things to consider before a vasectomy?

Nothing specific...: Nothing specific is required, but the following is useful" - realize it is a permanent measure for male contraception; vasectomy reversal would cost 10-20 times for vasectomy and usually not be covered by insurance; - expect some intraoperative tucking pressure and ache, and some self-limiting postop ache and bruise; - continue precaution against pregnancy until post-vas semen exam shows no sperm.
