Although existing research has shown that the APRI-BT satisfies the assumption of measurement invariance across age and gender, these findings come from western individualistic countries (e.g., Australia). This study aimed to investigate the factorial structure and measurement invariance across age, gender, and clinical status in a sample of Romanian youths. Participants were 1,024 adolescents, 10 to 18 years, recruited from both community and clinical setting. Our results confirmed a six first-order factor structure and two second-order factors (Bully including Bullying Physical, Bullying Verbal, Bullying Social and Victimization including Physical Victimization, Verbal Victimization, Social Victimization). In addition, measurement invariance across age, gender, and clinical status was demonstrated. This study identifies APRI-BT as an instrument with solid psychometric proprieties for measuring bullying and victimization among preadolescents and adolescents.Objective To investigate effect of microsurgical varicocele repair on sexual functions and serum total testosterone level in infertile hypogonadal men with varicocele, and also to determine factors that might predict improvement in total testosterone level after surgery.Methods The study included 202 infertile hypogonadal men (total testosterone level of less then 3.5 ng/mL) with varicocele who underwent microsurgical sub-inguinal varicocele repair.Results Mean serum total testosterone level significantly increased from 2.55 ± 0.66 ng/mL to 3.72 ± 1.34 ng/mL after varicocelectomy (p = .000), and 105 patients (52%) had serum total testosterone level of ≥3.5 ng/mL after the surgery. Mean international index of erectile functions (IIEF-EF) score significantly increased from 27.47 ± 2.96 to 28.61 ±
