title: The relationship between mean platelet volume and other platelet indices with testicular artery blood flow and fertility: a preliminary study.
abstract: OBJECTIVE
  To examine the relationship between platelets (PLT) and platelets indices such as mean platelet volume (MPV), platelet distribution width (PDW), and plateletcrit (PCT) as noninvasive biomarkers with testicular artery blood flow and fertility.
  
  
  METHODS
  Fifty-seven healthy and fertile men with normal semen values and 52 patients with abnormal semen values were included in the study. The participants' PLT, MPV, PDW and PCT values were analyzed. Four different levels of the testicular artery, peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistive index (RI) were measured using color Doppler ultrasound.
  
  
  RESULTS
  There was no significant difference in terms of platelet and platelet indices (MPV, PDW and PCT) between the fertile and infertile group. There were no between group differences in the RI values of the testicular- and intra-testicular artery. When all fertile and infertile participants were considered together, there was no statistically significant correlation between the parameters of the testicular artery blood flow (PSV, EDV and RI) and platelet and platelet indices (MPV, PDW and PCT) (P > 0.05).
  
  
  CONCLUSIONS
  There is not statistically significant correlation between any of the following parameters: platelets and platelet indices such as MPV, PDW and PCT, RI of the testicular artery, and fertility.
