Hyperandrogenism is a common reason for consultation, the causes of which can range from common conditions (PCOS) to rarer conditions with major genetic implications (NC21OHD). It is characterized by elevated levels of circulating androgens, mainly testosterone. This excess of androgens usually manifests clinically as increased male-pattern hair growth and, less specifically, acne and alopecia. Its prevalence is estimated at between 6 and 12% in women of reproductive age, and its incidence is increasing.

It is also responsible for infertility. As a reminder, infertility is a major public health issue and affects more and more couples around the world.

The investigators therefore wish to develop innovative tools to improve the diagnosis and management of hyperandrogenism

Inclusion Criteria:

• Patients of childbearing age (16 to 45 years old)
• Suffering from hyperandrogenism
• Established etiological diagnosis with elimination of differential diagnoses
• Informed and not opposed to the collection of their data for the purposes of the study

Exclusion Criteria:

• Pregnancy
• Patients under legal protection measures

The first stage of the study will involve participating centers selecting patients' medical records after verifying their eligibility. It should be noted that the control group will consist of a population for whom tests were carried out for symptoms that were ultimately ruled out with normal results.

The procedures carried out with the French data privacy authority (CNIL, Commission nationale de l'informatique et des libertés) do not provide for the transmission of the database, nor do the information and consent documents signed by the patients.

Consultation by the editorial board or interested researchers of individual participant data that underlie the results reported in the article after deidentification may nevertheless be considered, subject to prior determination of the terms and conditions of such consultation and in respect for compliance with the applicable regulations.

Beginning 3 months and ending 3 years following article publication. Requests out of these time frame can also be submitted to the sponsor

Researchers who provide a methodologically sound proposal.
