How safe are saline infusions into the. Scrotum to enlarge? I've seen fetish videos and am curious to try it.

Unsafe. Do not have anything to do with anyone who suggests such a procedure.Unless the saline is inected inro a previously surgically placed tissue expander. This is occasionally used in very young children who require scrotal expansion to accomodate undescended testes or a testicular prosthesis. Saline infusions could well become infected and cause an abscess. Would be temporary till saline is absorbed.
Scrotum infusion. This is dangerous and may cause severe damage...Testes function or damaged is also possible.
