research Interventions for Hirsutism (Excluding Laser and Photoepilation Therapy Alone)

33 citations , April 2015 in “Cochrane library”

This review examined various treatments for hirsutism and found low to very low quality evidence suggesting that flutamide and spironolactone may help reduce hair growth, while metformin was ineffective.

research Non-Classic Congenital Adrenal Hyperplasia

42 citations , April 2013 in “Steroids”

This review discusses the pathophysiology, molecular genetics, and management of non-classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency, with no new clinical findings reported.

research Epidemiology, Diagnosis, and Management of Hirsutism: A Consensus Statement by the Androgen Excess and Polycystic Ovary Syndrome Society

378 citations , November 2011 in “Human reproduction update”

This review discusses the epidemiology, causes, diagnosis, and management of hirsutism in women, noting that effective treatment requires addressing the root cause as well as the hair growth.

research Phenotypic Profiling of Parents With Cryptic Nonclassic Congenital Adrenal Hyperplasia: Findings in 145 Unrelated Families

62 citations , March 2011 in “European journal of endocrinology”

This study found that parents identified with cryptic NCCAH through genetic testing are mostly asymptomatic but may experience temporary female infertility and require glucocorticoid stress coverage in specific circumstances.

research The Androgen Excess and PCOS Society Criteria for the Polycystic Ovary Syndrome: The Complete Task Force Report

1540 citations , October 2008 in “Fertility and Sterility”

This review discusses the definition of polycystic ovary syndrome proposed by the AE-PCOS Society Task Force, emphasizing hyperandrogenism, ovarian dysfunction, and excluding related disorders, while noting potential variations needing more research.

research Evaluation and Treatment of Hirsutism in Premenopausal Women: An Endocrine Society Clinical Practice Guideline

502 citations , February 2008 in “The Journal of Clinical Endocrinology & Metabolism”

This review discusses hirsutism management guidelines, recommending androgen testing only for women with abnormal hirsutism scores and advocating for combined therapy approaches depending on severity and underlying conditions, but it reports no new clinical results.

A Prospective Study of the Prevalence of Nonclassical Congenital Adrenal Hyperplasia Among Women Presenting with Hyperandrogenic Symptoms and Signs

research A Prospective Study of the Prevalence of Nonclassical Congenital Adrenal Hyperplasia Among Women Presenting with Hyperandrogenic Symptoms and Signs

150 citations , November 2007 in “The Journal of Clinical Endocrinology and Metabolism”

This study determined that nonclassical congenital adrenal hyperplasia has a 2.2% prevalence among hyperandrogenic women in Spain, with basal serum 17-hydroxyprogesterone showing excellent diagnostic performance.

research A Randomized Bilateral Vehicle-Controlled Study of Eflornithine Cream Combined with Laser Treatment Versus Laser Treatment Alone for Facial Hirsutism in Women

125 citations , February 2007 in “Journal of the American Academy of Dermatology”

This study found that adding topical eflornithine to laser hair removal significantly improved the reduction of unwanted facial hair in women over a 6-month period, compared to laser treatment alone.

research Androgen Excess in Women: Experience with Over 1000 Consecutive Patients

947 citations , February 2004 in “The Journal of Clinical Endocrinology and Metabolism”

In this study, polycystic ovary syndrome was the most prevalent cause of androgen excess, and suppressive hormonal therapy improved hirsutism, menstrual dysfunction, and acne in most patients, though side effects were common.
