The purpose of this study is to evaluate the family history, clinical and endocrine status of patients with androgenetic alopecia. 736 patients with androgenetic alopecia who had visited Dept. of Dermatology, Chung Ang University during the 2 years from January, 1999 to December, 2000 were examined. Results were as follows: 1) Male patients(571) are more common than female patients(165). They are mostly in the twenties(male patients: 325; 56.9%, female patients: 45; 27.3%). 2) In the 571 male patients, Hamiton-Norwood type IIIv is predominant(99 patients: 17.3%). In the 165 female patients Ludwig type I is predominant (103 patients: 62.4%). 3) 340 patients(59.5%) among 571 male patients and 51 patients(30.9%) among 165 female patients have family history. 4) The most common accompanying disorder is seborrheic dermatitis(male patients: 349; 62.2%, female patients: 94; 57.0%). 5) Serum testosterone levels are increased in 78 male patients(13.7%) and 23 female patients(13.9%) This results suggest that those who want to treat androgenetic alopecia at earlier ages are gradually increasing. And it seems to believe that the age, genetic factors, localized effects of androgens on the scalp and the density and/or functional activity of androgen receptors may influence the pathogenesis of androgenetic alopecia.
