DSD
Also written as: DSD — Disorders of Sex Development
Conditions where chromosomal, gonadal, or anatomical sex development differs from typical male or female patterns.
Full Definition
Disorders of sex development encompass a diverse group of congenital conditions characterized by atypical development of chromosomal, gonadal, or anatomical sex characteristics. DSD can be classified into three main categories: sex chromosome DSD (such as Turner or Klinefelter syndromes), 46,XY DSD (including androgen insensitivity syndrome and 5α-reductase deficiency), and 46,XX DSD (primarily congenital adrenal hyperplasia). These conditions may present with ambiguous genitalia at birth, discordant pubertal development, or primary amenorrhea. Management requires a multidisciplinary approach involving pediatric endocrinologists, urologists, psychologists, and genetic counselors. The current terminology emphasizes medical precision while respecting patient dignity and avoiding stigmatizing language.
Usage
Usage note: Preferred term over older terminology like 'intersex' or 'hermaphroditism' in clinical documentation.
