Hey people. I noticed female circumcision at the top says "also known as female genital mutilation (fgm)" well we have to be fair and make sure everyone knows where to find this page. So, let's say right after the first word, "also known as male genital mutilation (mgm)"
After all, some people do call it that. That's what "also known as" means. Here is some proof.
