Objectives: The aim of this study was to determine whether the environmental exposure to pyrethroids affects semen quality and the level of reproductive hormones in men.

Methods: The study population consisted of 334 men who attended the infertility clinic for diagnostic purposes and who had normal semen concentration of 15 to 300 mln/mL. Participants were interviewed and provided a semen sample. The pyrethroids metabolites—3-phenoxybenzoic acid (3PBA), cis-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane carboxylic acid (CDCCA), trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane carboxylic acid (TDCCA), and cis-2,2-dibromovinyl-2,2-dimethylcyclopropane-1-carboxylic acid (DBCA) were analyzed in the urine using a validated gas chromatography ion-trap mass spectrometry method.

Results: Urinary pyrethroids metabolites levels were significantly associated with an increase in the percentage of sperm with abnormal morphology and decrease in sperm concentration, the level of testosterone, and computer-aided semen analysis parameters.

Conclusions: Environmental pyrethroids exposure may affect semen quality and the level of reproductive hormones.
