The prevalence of varicocele in employees of musician and transport units of AJA University of medical sciences was evaluated. In a cross-sectional study 42 musician and 31 individuals from transport unit of AJA University of medical sciences enrolled. The varicocele was evaluated in left and right testis. The prevalence and grad of varicocele were analysed by χ 2 and P<0. 05 was statistically considered significant. The results showed that the prevalence of varicocele in the musician unit (31%) was significantly higher than in the transport unit (10%) (P=0. 032)، and in the left testis was significantly higher than the right testis. The grad of varicocele in the musician unit was also significantly higher than the transport unit. It seems that the prevalence and grad of varicocele in the left testis are higher than in the right testis and are also high in musicians who their activities are accompany with valsalva manoeuvre.
