Differences of sex development (DSD) occurs when the development of chromosomal sex, gonadal or internal/external genitalia is atypical. It has an incidence of 1: 1000-4500 live born children. New chromosomal array technologies (SNP-array) can analyze the genome of the individual providing information of copy number variation (CNV) of specific chromosomal regions helping to identified pathogenic variants that could explain the etiology of the DSD. This study aims to analyze th...

Background/Aims: 46,XY gonadal dysgenesis (GD) is classified as complete (CGD) or partial (PGD) depending on gonadal morphology and function. In contrast to the typical female external genitalia in CGD, the phenotype of PGD is variable depending on androgen production. A diagnosis of PGD is based on clinical/biochemical features, gonadal histology and genetic findings. The aim of this study is to characterise these features, particularly histological, in a lar...
