What are the best treatments for Androgen Insensitivity Syndrome?

Androgen Insensitivity Syndrome (AIS) management focuses on personalized care, including hormone replacement therapy, surgical consultation for gonad management, and specialized psychological support. Because Androgen Insensitivity Syndrome presents along a spectrum—ranging from Complete (CAIS) to Partial (PAIS)—treatment must be tailored to the individual’s specific phenotype and clinical needs.

What are the primary treatment approaches for Androgen Insensitivity Syndrome?

Treatment for Androgen Insensitivity Syndrome is multidisciplinary and must be individualized. For individuals with CAIS, the primary focus is typically estrogen replacement therapy (ERT) to promote bone health and prevent symptoms of menopause after gonadectomy. In cases of PAIS, treatment may involve more complex hormonal management and, in some instances, surgical interventions to address genital ambiguity or functional concerns, always conducted with deep sensitivity to patient autonomy.

Which specialists should be on the care team?

Managing Androgen Insensitivity Syndrome requires a coordinated team to address physical and emotional health. A comprehensive care team typically includes:

• Endocrinologist: To manage hormonal health and bone density.


• Gynecologist or Urologist: To provide expertise on reproductive anatomy.


• Clinical Psychologist: To provide essential support regarding gender identity and psychosocial development.


• Clinical Geneticist: To provide clarity on the underlying AR gene mutation.

What non-pharmacological and surgical options exist?

Non-pharmacological care is vital for those living with Androgen Insensitivity Syndrome. This may include pelvic floor physical therapy or the use of vaginal dilators to address vaginal hypoplasia. Surgical decisions regarding the timing of gonadectomy—often delayed until after puberty to allow for natural growth—are complex and require shared decision-making between the patient and their clinical team to balance cancer risk with hormonal development.

How does treatment effectiveness vary?

Effectiveness varies significantly based on the degree of androgen receptor function. While Androgen Insensitivity Syndrome is classified by these degrees, every patient's experience is unique. Currently, there are no curative pharmacological treatments for the underlying genetic mutation; therefore, care focuses on quality of life and long-term health maintenance.
