 The goal of early transition surgeries was the removal of hormone-producing organs (such as the testicles and the ovaries) in order to reduce their masculinizing or feminizing effects.Later, as surgical technique became more complex, the goal became to produce functional sex organs from sex organs that are already present in the patient.In the US in 1917, Dr. Alan L. Hart, an American TB specialist, becomes one of the first female-to-male transsexuals to undergo hysterectomy and gonadectomy for the relief of gender dysphoria.
