Evaluation of the semen quality of patients attended in a clinical analyzes in the Cascavel municipality, Brazil

The objective of this study was to investigate the prevalence of altered spermograms of individuals living in a municipality in the west of Paran and attended at a private laboratory for clinical analysis, as well as the main alterations found in this study. Methods: We analyzed electronic reports of patients undergoing sperm examination in a private laboratory located in the municipality of Cascavel, Paran, from January 2014 to December 2016. Results: It was verified that of 888 tests analyzed, only 1% presented all parameters analyzed within normality, while 99% of the cases presented some type of alteration. There was a change in the following parameters with statistical significance between the number of reports analyzed: time of liquefaction, sperm concentration, head anomalies, tail abnormalities, number of spermatocytes and spermatids (p <0.0001), viscosity (p = 0.1098), live forms (p = 0.0524), progressive motility (p = 0.0010) and total motility (p = 0.0013). Conclusions: There was a high prevalence of altered spermograms and a great number of alterations were observed, which requires the need for complementary tests to determine the causes of these alterations.
