In the last few decades with the industrial revolution many environmental contaminants have estrogenic activity (endocrine disruptors, EDs) are released into the environment affecting the male reproductive system and male fertility. Sperm motility is one of the initial tests performed to assess sperm function; only motile sperm can achieve fertilization in vivo. The present study aimed to investigate the possible effects of a group of EDs that represent a widespread chemicals in the environment genistein (Gen), is a naturally occurring isoflavone (100 μM), bisphenol A (BPA), that is used in the manufacture of plastics and other products and released largely into the environment (100 μM), nonylphenol (NP) is an important environmental toxicant and potential endocrine disrupting chemical (10 μg/ml), TCDD, that is formed as an unwanted by-product in the manufacture of chlorinated hydrocarbons (2.5 μg/ml), atrazine (Atraz) is a herbicides (500 μM), dibromochloropropane (DBCP) is a pesticide (10 μg/ml), and diazinone (Diaz) is a insecticide (500 μM) on human sperm motility and kinematic characteristics. Human spermatozoa were incubated in Ham's F10 media with/without the tested chemicals or DMSO as positive control for 6 hr at 37℃ in 5% CO2. Then, sperm motility was assessed using computer assisted semen analyzer. Interestingly, all the chemicals tested significantly decreased sperm motility as compared to the control groups. However, only Diaz significantly decreased sperm kinematic characteristics namely, VCL, VSL, STR, VAP, and ALH. We suggest that the environmental chemicals may have an effect on male fertility via decreasing sperm motility.
