New to Cyproterone? There is a guide in the encyclopedia. Read the guide → Studysummary In this study, the researchers observed that antiandrogen treatment with Cyproterone acetate led to atrophy of pilo-sebaceous units and may activate Langerhans cells, contributing to local inflammation. Our plain-language summary of this paper — not a Tressless recommendation.
The study analyzed the effects of Cyproterone acetate (CPA) on pilo-sebaceous units in 14 hirsute women over 12 months. Biopsies showed an increased number of hair follicles and sebaceous gland hyperplasia before treatment. Post-treatment, 64.2% of cases exhibited atrophy of pilo-sebaceous units, with noticeable inflammatory infiltrate and basal layer vacuoles. Six cases showed marked hyperplasia of Langerhans cells. The findings suggested that antiandrogen treatment led to hair follicle and sebaceous gland atrophy, with Langerhans cell activation and inflammation as local consequences of hair follicle involution.
