mutilation that will likely lead to suicide
I haven't seen any studies that have eliminated enough factors (socialital, economic, employment, state of interpersonal relationships, follow up therapy, previous underlying conditions, etc) out of the equation out right states that reassignment surgery itself leads to suicide.
And the surgery by itself probably wouldn't curb or cure the already higher among the general population suicide rates. Because of all the other factors being coming up short and it's only part of the transition. Not to mention if they even wanted surgery. They do not all need it to relieve their dysmorphia.
