Major study launches to uncover hidden health risks in androgen insensitivity
NCT ID NCT04708431
First seen Jun 27, 2026 · Last updated Aug 14, 2026 · Updated 9 times
Summary
This study follows 650 people aged 8 to 99 with androgen insensitivity syndrome (AIS) to better understand their long-term health. Researchers will track hormones, bone density, heart health, metabolism, and tumor risk through regular check-ups and scans. No treatments are being tested; the goal is to learn how AIS affects the body over time and improve future care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could provide a clearer picture of long-term health risks and optimal monitoring for people with androgen insensitivity syndrome.
- What could go wrong
- This is an observational study with no treatment being tested, so it will not directly lead to new therapies. Results may take years to emerge and may not apply to all forms of AIS.

* INCLUSION CRITERIA: Inclusion Criteria for AIS Subjects In order to be eligible to participate in this study, an individual must meet all the following criteria: 1. Individuals ages 8-99 years old with known androgen insensitivity based on pathologic androgen receptor gene mutation or based on clinical diagnosis of complete androgen insensitivity (CAIS) based on 46 XY karyotype, presence of testis, absence of uterus, high testosterone without signs of virilization at birth or during puberty and/or multiple members in the family also presenting with clinical CAIS. 2. Identify as male or female 3. Patients with both complete, partial, and mild androgen insensitivity are eligible 4. Stated willingness to comply with all study procedures and availability for the duration of the study 5. Ability of subject or guardian to understand and the willingness to sign and date a written informed consent document. Inclusion Criteria for Relative of AIS Subjects 1\) Adult Relatives of patients with AIS EXCLUSION CRITERIA: Exclusion Criteria for AIS Subjects 1. An individual who meets any of the following criteria will be excluded from participation in this study: Patients with other diagnoses such as partial or complete gonadal dysgenesis, 5-alpha reductase deficiency, and 46 XY. If, following a diagnostic work-up, a patient is determined to have causes for 46 XY DSD other than androgen insensitivity; they will no longer be followed on this protocol. They will have the opportunity to continue care with the team under the Data Collection Protocol or may be referred to an expert or multidisciplinary DSD team in the community. 2. Patients with significant non-endocrine medical conditions. Exclusion Criteria for Relative of AIS Subjects 1\) Patients with significant non-endocrine medical conditions.
