The most prevalent DSD type was 46, XY DSD (61.2%), followed by 46, XX DSD (19.7%) and sex chromosome DSD (19.1%). Among people with 46, XY DSD, androgen biosynthesis disorders were dominant, particularly 5-a reductase 2 deficiency (46.7%). Among 46, XX DSDs, the most common subtype was androgen excess disorders (51.7%) comprising 21a-hydroxylase deficiency (48,3%) and 11\u03b2-hydroxylase deficiency (3.4%). Turner syndrome was most prevalent among sex chromosome DSD (71.4%) with others being Klinefelter syndrome, 45, XO\/46, XY mixed gonadal dysgenesis and 46, XX\/46, XY chimerism. The degree of ambiguity was variable depending on the type of DSD and similarly, sex assignment at birth was influenced by the level of ambiguity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The study underscores the significance of comprehensive approaches for DSD diagnosis and management, especially in regions with limited resources.
