[Differences of Sex Development (DSD): Controversies and Challenges]

Area of Science:

• Endocrinology
• Genetics
• Pediatrics

Background:

• Differences of Sex Development (DSD) encompass conditions with atypical chromosomal, gonadal, or anatomical sex.
• While DSD 46,XX (e.g., congenital adrenal hyperplasia) are often clear, DSD 46,XY present diagnostic challenges due to complex gene involvement in gonad development.
• Approximately half of DSD 46,XY cases remain undiagnosed despite advanced genetic technologies like exome sequencing and next-generation sequencing (NGS).

Purpose of the Study:

• To review the primary causes of Differences of Sex Development (DSD).
• To discuss recent advancements and challenges in the clinical management of DSD.
• To address the psychosocial aspects, including patient identity and quality of life, associated with DSD.

Main Methods:

• Literature review of DSD causes and management strategies.
• Analysis of current diagnostic approaches, including genetic testing (exome, NGS).
• Discussion of treatment options, fertility considerations, and long-term patient outcomes.

Main Results:

• DSD 46,XX cases, such as congenital adrenal hyperplasia, are generally well-defined.
• DSD 46,XY diagnoses are complicated by the genetics of bipotential gonad development, leading to diagnostic uncertainty in many instances.
• Despite technological advances, a significant proportion of DSD cases remain undiagnosed, highlighting ongoing diagnostic hurdles.

Conclusions:

• The management of DSD is intricate, necessitating a multidisciplinary approach to address medical, surgical, fertility, and psychosocial aspects.
• Long-term consequences for patients require thorough discussion, focusing on quality of life and personal identity.
• Societal integration and acceptance of individuals with DSD are critical components of comprehensive patient care.
