Objectives: The purpose of this study is to determine the family history and the clinical and endocrine statuses of patients with androgenetic alopecia.

Methods: We have gained some results through the clinical study of 580 androgenetic alopecia patients who visited the Alopecia Clinic at the Department of Dermatology, Chung Ang University Hospital between January of 2002 to December of 2003.

Results: 1) Male patients (353) are 1.6 times more common than female patients (227). They are mostly in the twenties(male 169; 48.0%, female 68; 30.0%). 2) In the 353 male patients, Norwood class II is dominant (106 patients; 30.0%). In the 227 female patients, Ludwig class I is more frequent 159 (70.0%). 3) 212 (60.0%) of the 353 male patients and 143 (63.0%) of  the 227 female patients have a family history. 4) The most common accompanying disorder is seborrheic dermatitis (male 247; 70.0%, female 148; 65.0%). 5) Serum testosterone levels were increased in 53 (15.0%) of the 353 males and 29 (12.8%) of the 227 females.

Conclusion: Based on our findings, the development of androgenetic alopecia is significantly related to a positive family history of baldness. Serum testosterone levels in most patients were within normal limits and were increased only in a small number of the patients with androgenetic alopecia.  Female androgenetic alopecia patients have increased in number and the male to female ratio is now 1.6:1.
