| Abstract: | This study examined the effects of exposure to p-Nonylphenol (NP) on the motility of the spermatozoa of Japanese medaka (Oryzias latipes). Spermatozoa collected from adult males reared for 2 weeks in aqueous solutions of 20 and 100 μg/L NP showed similar swimming speeds but significantly lower percentages of motile spermatozoa than those of untreated controls. These results suggest that even a short exposure to NP might reduce significantly spermatozoan viability in fish. |
