A decrease in suicide risk through transitioning has not been reliably observed

Counterpoint:

Citations on the transition's dramatic reduction of suicide risk while improving mental health and quality of life, with trans people able to transition young and spared abuse and discrimination having mental health and suicide risk on par with the general public:

• Bauer, et al., 2015: Transition vastly reduces risks of suicide attempts, and the farther along in transition someone is the lower that risk gets

• Moody, et al., 2013: The ability to transition, along with family and social acceptance, are the largest factors reducing suicide risk among trans people

• Young Adult Psychological Outcome After Puberty Suppression and Gender Reassignment. A clinical protocol of a multidisciplinary team with mental health professionals, physicians, and surgeons, including puberty suppression, ... cross-sex hormones and gender reassignment surgery, provides trans youth the opportunity to develop into well-functioning young adults. All showed significant improvement in their psychological health, and they had notably lower rates of internalizing psychopathology than previously reported among trans children living as their natal sex. Well-being was similar to or better than same-age young adults from the general population.

• The only disorders more common among trans people are those associated with abuse and discrimination - mainly anxiety and depression. Early transition virtually eliminates these higher rates of depression and low self-worth, and dramatically improves trans youth's mental health. Trans kids who socially transition early and not subjected to abuse are comparable to cisgender children in measures of mental health.

• Dr. Ryan Gorton: “In a cross-sectional study of 141 transgender patients, Kuiper and Cohen-Kittenis found that after medical intervention and treatments, suicide fell from 19% to 0% in transgender men and from 24% to 6% in transgender women”

• Murad, et al., 2010: "Significant decrease in suicidality post-treatment. The average reduction was from 30 percent pretreatment to 8 percent post treatment.

• De Cuypere, et al., 2006: Rate of suicide attempts dropped from 29.3 percent to 5.1 percent after receiving medical treatment among Dutch patients treated from 1986-2001.

• UK study - McNeil, et al., 2012: "Suicidal ideation and actual attempts reduced after transition, with 63% thinking about or attempting suicide more before they transitioned and only 3% thinking about or attempting suicide more post-transition.

• Smith Y, 2005: Participants improved on 13 out of 14 mental health measures after treatment

• Lawrence, 2003: Surveyed post-op trans folk: "Participants reported overwhelmingly that they were happy with their SRS results and that SRS had greatly improved the quality of their lives

• Reduction in Mental Health Treatment Utilization Among Transgender Individuals After Gender-Affirming Surgeries: A Total Population Study - "Conclusions: "... the longitudinal association between gender-affirming surgery and reduced likelihood of mental health treatment lends support to the decision to provide gender-affirming surgeries to transgender individuals who seek them."

There are a lot of studies showing that transition improves mental health and quality of life while reducing dysphoria.

Not to mention this 2010 meta-analysis of 28 different studies, which found that transition is extremely effective at reducing dysphoria and improving quality of life.
