The politically correct, terrified psychiatric consensus may say that to avoid being targeted by Social Justice Dipshits, but that's not what clinical studies show. See the link below, which tracked post-surgery individuals and found increased rates of suicide.

The tl;dr:

Mortality from suicide was strikingly high among sex-reassigned persons, also after adjustment for prior psychiatric morbidity. In line with this, sex-reassigned persons were at increased risk for suicide attempts. Previous reports [6], [, [10], [11] suggest that transsexualism is a strong risk factor for suicide, also after sex reassignment, and our long-term findings support the need for continued psychiatric follow-up for persons at risk to prevent this.
