Increases in platelet count and platelet indices such as mean platelet volume (MPV), platelet distribution width (RDW) and plateletcrit (PCT) have been reported in a wide range of pathological settings. The aetiology of varicocele, a vascular disease, is poorly defined. In this study, we aimed to examine the relationship between varicocele, platelet count and a series of platelet indices. A total of 69 patients with varicocele and 56 patients without varicocele were enrolled in the study. Patient sperm parameters, platelet,
MPV, PDW and PCT values were analysed. There were semen abnormalities in 37 (53.6%) patients in the varicocele group and 19 (33.9%) patients in nonvaricocele group (P < 0.05). There was no significant difference in platelet count or platelet indices (MPV, PDW and PCT) between the patients with and without varicocele (P < 0.05). There was no statistically significant difference in platelet count or MPV, PDW and PCT between patients with varicocele and the control subjects.
