aPatients with early-onset AGA with at least one of the following parameters: body mass index (BMI) >25 Kg/m2, insulin-resistance (IR), and/or sex hormone-binding globulin (SHBG) <25 nmol/l. bPatients with early-onset AGA which did not satisfy any of the aforementioned criteria. compared to controls; compared to Group 2; compared to controls; compared to Group 2 (Student’s t-test). The DNA fragmentation was evaluated through TUNEL test. Results are expressed as mean value (standard deviation).
