A new study has found that exposure to glyphosate-based herbicides (GBHs), including Roundup, caused reproductive and developmental effects in both male and female rats, at a dose level currently considered safe in the U.S. (1.75 mg/kg bw/day).

Exposure to GBHs was associated with androgen-like effects, including a statistically significant increase of anogenital distance (AGD) in males and females, delay of first estrous and increased testosterone in females.
