Context:

Androgen insensitivity syndromes (AIS) represent a spectrum of disorders arising from genetic mutations affecting androgen receptor signaling.
These conditions present complex diagnostic challenges, particularly in differentiating between various forms of partial and complete androgen resistance.

Purpose:

To explore the differential diagnosis of 5 alpha reductase deficiency and androgen receptor defects.
To discuss the critical considerations and implications of sex assignment in individuals with disorders of sex development (DSD).

Summary:

The review focuses on two primary areas: 5 alpha reductase deficiency, an enzyme defect impacting testosterone metabolism, and androgen receptor defects, leading to impaired androgen action.
It emphasizes the diagnostic complexities in distinguishing between different androgen resistance syndromes and the ethical and clinical considerations surrounding sex assignment in ambiguous genitalia cases.

Impact:

Provides a framework for clinicians to approach the diagnosis of DSD related to androgen synthesis and action.
Informs clinical decision-making regarding sex assignment, aiming to improve patient outcomes and quality of life.
