Congenital Androgen Insensitivity Syndrome - Disorder of Sex Development

Learn about Congenital Androgen Insensitivity Syndrome (CAIS), a disorder of sex development (DSD) that affects the reproductive system's response to androgens. Explore the pathophysiology of androgen insensitivity, including the role of androgen receptors and testosterone in normal sexual development. Understand how mutations in androgen receptors lead to the clinical presentation of CAIS, where individuals with XY chromosomes develop female external genitalia despite having testes. Examine the hormonal mechanisms involving testosterone, dihydrotestosterone (DHT), and estrogen in sexual differentiation. Study the embryological development of reproductive structures, including the differentiation of Wolffian and Müllerian ducts, and how androgen insensitivity affects this process. Discover the clinical features of CAIS, including the presence of testes, absence of internal female reproductive structures, and typical female external appearance. Review diagnostic approaches, management strategies, and the psychological and social considerations for patients with this condition. Gain insights into the broader category of disorders of sex development and their impact on reproductive health and fertility.
