Research cited in this study

23 / 23 results

research Parenteral and Oral Cyproterone Acetate Treatment in Severe Hirsutism

5 citations , March 2010 in “Gynecologic and obstetric investigation”

This study found that parenteral administration of cyproterone acetate was more effective than high-dose oral treatment in reducing facial hair diameter and improving dermatological parameters in patients with severe hirsutism, despite similar androgen suppression.

research An Open Randomized Comparative Study of an Oral Contraceptive Containing Ethinyl Estradiol and Cyproterone Acetate with and without the GnRH Analogue Goserelin in the Long-Term Treatment of Hirsutism

18 citations , March 2010 in “Gynecologic and obstetric investigation”

This study found that both combined therapy with goserelin and oral contraceptives, and oral contraceptives alone, significantly reduced hair diameter in severe hirsutism without a significant difference between treatments.

research Comparison of Diane 35 and Diane 35 Plus Finasteride in the Treatment of Hirsutism

50 citations , April 2000 in “Fertility and Sterility”

This study found that a combination therapy of Diane 35 with finasteride was more effective at reducing hirsutism scores in women with idiopathic hirsutism or polycystic ovary syndrome after 3 months compared to Diane 35 alone.

research Antiandrogen Treatment of Polycystic Ovary Syndrome

52 citations , June 1999 in “Endocrinology and Metabolism Clinics of North America”

This review concludes that antiandrogens with ovarian suppression may significantly improve hirsutism and androgenetic alopecia in women with PCOS, but treatment needs to continue unless the underlying PCOS cause is addressed.

A Prospective Randomized Trial Comparing Low Dose Flutamide, Finasteride, Ketoconazole, and Cyproterone Acetate-Estrogen Regimens in the Treatment of Hirsutism

research A Prospective Randomized Trial Comparing Low Dose Flutamide, Finasteride, Ketoconazole, and Cyproterone Acetate-Estrogen Regimens in the Treatment of Hirsutism

113 citations , April 1999 in “The Journal of Clinical Endocrinology and Metabolism”

This study found that all four treatments—flutamide, finasteride, ketoconazole, and EE-CPA—significantly reduced hirsutism, but EE-CPA and flutamide appeared most effective, with varying effects on androgen levels and side-effect profiles.

research Treatment of Hirsutism: Comparisons Between Different Antiandrogens with Central and Peripheral Effects

75 citations , March 1999 in “Fertility and sterility”

This study concluded that finasteride, cyproterone acetate, and flutamide were similarly effective at reducing hirsutism in women, though they acted through different mechanisms.

research Hirsutism II: Treatment

15 citations , August 1998 in “Australasian journal of dermatology”

This review discusses various treatments for hirsutism, including cosmetic techniques, anti-androgens like spironolactone, and new drugs such as finasteride and flutamide, but it reports no new clinical results.

49 citations , June 1998 in “Journal of Endocrinological Investigation”

In this study, both cyproterone acetate-estrogen combination (Diane®) and finasteride were effective in reducing hirsutism, but Diane® showed greater long-term efficacy and cost-effectiveness.

research Oral Contraceptives and Cyproterone Acetate in Female Acne Treatment

4 citations , December 1994 in “PubMed”

This study found that treatment with cyproterone acetate and estradiol improved emotional well-being and acceptance of being viewed among women with hirsutism, with no significant differences between oral and transdermal estradiol groups.

research Cyproterone Acetate for Severe Hirsutism: Results of a Double-Blind Dose-Ranging Study

94 citations , July 1991 in “Clinical endocrinology”

In this study, cyproterone acetate at 2 mg daily was found to be as effective as higher doses in reducing hair growth for hirsute women over 12 months.

research Hirsutography: Photographic Measurement of Linear Hair Growth in Hirsute Women During Comparison of Anti-Androgen Treatments

4 citations , January 1991 in “Journal of obstetrics and gynaecology”
