We present the results from an investigation over the incidence and age distribution of androgenetic alopecia (AA) among a large group of young adults- soldiers and young men that were to be enlisted. The degree of familial heredity was also investigated. 502 males from 18 to 19 years of age were examined. The presence of AA in each participant was confirmed by inspection. The evaluation of the clinical stage of AA was determined according to the modified version of the Hamilton-Norwood scale. The type of hair distribution over the body and the other signs of tissue hyperandrogenemia were also identified. The data about their familial history were collected by means of a direct inquiry and the subjective assessment of the investigated people about the state of their hair was also considered. Results: In 123 (24,5%) from the investigated men early signs of AA were established, in 47 (9,36%)- AA was II degree and in 1 person (0,19%)- III degree. In 41 (23,9%) of the AA patients we observed positive familial history of AA with more paternal than maternal relatives. In 48 (28%) of the participants AA was associated with acne vulgaris. Conclusion: The incidence of AA in the explored population is high. The initial signs of AA have an onset earlier than 17 years of age. 1/3 of the persons with AA have positive familial history and present frequent association with acne vulgaris.
