Exploration of hirsutism: elements for a strategy.

Area of Science:

• Endocrinology
• Reproductive Medicine

Background:

• Hirsutism, characterized by excess androgen production, affects numerous women.
• Establishing an efficient diagnostic strategy for hirsutism is crucial for effective management.

Purpose of the Study:

• To determine the optimal diagnostic strategy for investigating hirsutism in women.
• To evaluate the diagnostic value of various hormonal assessments and stimulation tests.

Main Methods:

• Investigation of 50 women presenting with hirsutism.
• Basal hormonal evaluations including serum testosterone, DHA-S, and LH.
• Luteinizing hormone-releasing hormone (LHRH) stimulation tests.
• Adrenocorticotropic hormone (ACTH) stimulation tests.
• Inhibition tests to assess hormonal control.

Main Results:

• Basal hormonal evaluations, especially serum testosterone, demonstrated significant diagnostic value.
• Dehydroepiandrosterone sulfate (DHA-S) and luteinizing hormone (LH) also provided valuable information.
• LH response to LHRH stimulation showed limited diagnostic utility.
• ACTH stimulation tests were useful for identifying enzyme deficiencies in cases with normal basal hormone levels.
• Inhibition tests were less effective in pinpointing the origin of hyperandrogenism but indicated hormonal control by ACTH and/or LH.

Conclusions:

• Basal hormonal assessments are the cornerstone for hirsutism exploration.
• ACTH stimulation tests are valuable for specific enzyme deficiency detection.
• Inhibition tests primarily clarify the regulatory control of androgen secretion rather than its source.
