The objective of this in vitro study was to determine the effect of nonylphenol (NP) as an environmental toxicant on the spermatozoa motility and viability. The dose- and time-dependent effect of nonylphenol (1, 10, 100 and 200 μg/mL) dissolved either in 0.1% dimethyl sulfoxide (DMSO) or 0.1% ethanol (ETOH) on the motility and viability of bovine spermatozoa, as a cell model, during several time periods (0 h, 2 h, 4 h and 6 h) were examined. The motility of spermatozoa was determined by the Sperm Vision(TM) CASA (Computer Assisted Semen Analyzer) system. The results showed decreased spermatozoa motility in all experimental groups with the addition of NP dissolved in 0.1% DMSO and 0.1% ETOH (P < 0.001 and P < 0.05). The lowest spermatozoa motility was found at doses > 100 μg/mL of NP in comparison with the control group. The viability of bovine spermatozoa detected by the MTT cytotoxicity assay was decreased significantly (P < 0.001) in all experimental groups with NP dissolved in 0.1% ETOH. The viability in groups with NP dissolved in 0.1% DMSO was significantly (P < 0.05) decreased at 1 μg/mL of NP and significantly decreased (P < 0.001) at doses > 10 μg/mL of NP. After 6 h of culture the MTT assay proved a negative effect of all NP doses the on cell viability. The obtained data clearly indicate the negative effect of NP as an endocrine disruptor on spermatozoa motility and viability, which should be seriously considered in the case of exposure to NP in animals and humans and as a reason of male reproductive dysfunction.

D013081 Sperm Motility Movement characteristics of SPERMATOZOA in a fresh specimen.
