Scientists Urge Testing of Pesticides Suspected in Low Male Reproductivity

Earlier this year, scientists from the National Institute of Environmental Health Sciences tested nine pesticides previously untested for their anti-androgenic effects. Androgens are male-characteristic hormones, and anti-androgenic substances keep the body from producing or using these hormones.

The study, done in conjunction with the Centre for Toxicology at the School of London, was initiated because “evidence suggests that there is widespread decline in male reproductive health and anti-androgenic pollutants may play a significant role. There is also a clear disparity between pesticide exposure and endocrine disrupting data, with the majority of the published literature focused on pesticides that are no longer registered for use in developed countries.”

Based on estimated anti-androgenic potency, current use, estimated exposure, and lack of previous data, the study concluded with a strong recommendation that dimethomorph, fludioxonil, fenhexamid, imazalil, ortho-phenylphenol and pirimiphos-methyl be tested for anti-androgenic effects in vivo.

All of these pesticides are in current use as fungicides, insecticides, or microbiocides used on farm crops, in landscapes, and for pest control.
