“Congruency the ART of Being Real” - 46XY DSD Due to 5 α Reductase Deficiency - Challenges in Decision Making

Abstract

Disorders of sexual development (DSDs) are heterogenous group of disorders characterized by discrepancy in chromosomal, gonadal, and phenotypic sex. DSD is a Medico-Social Emergency. 5 α reductase type 2 deficiency is one of the rare causes of 46 XY DSD. The degree of under virilization varies from clinically female to a near male phenotype. Müllerian structures were absent. At puberty, there might be features of virilization. Gender incongruence or dysphoria occurs frequently during puberty. An important marker for diagnosis is an elevated testosterone to dihydrotestosterone ratio in the basal state or following HCG stimulation. All 46 XY DSD require an appropriate molecular diagnosis prior to gender assignment and gender reassignment surgery. Gender reassignment surgery and/or Gonadectomy should be performed only after 18 years if there are compelling indications like suspicion of malignancy or presence of gender dysphoria or gender incongruence.
