Аннотация
The goal of this study was to examine the potential transgenerational inheritance of anti-androgenic effects induced by Vinclozolin administered intraperitoneally to pregnant Wistar rats (Crl:WI[Han]). Dams were dosed with Vinclozolin at 0, 4 or 100mg/kg bw/d on gestation days 6-15. Male offspring of F1-F3 generations were bred with untreated females to yield F2-F4 offspring. No evident anti-androgenic effects were observed at 4mg/kg bw/d, but a case of hypospadias as well as delayed sexual maturation in F1 male offspring was observed as a sign of anti-androgenicity at 100mg/kg bw/d. However, F1-F3 males developed normally to sexual maturity and were able to mate and to generate healthy progeny. Sperm count, morphology and motility were not affected in F1-F4 generation male offspring. In conclusion, transgenerational inheritance of Vinclozolin's anti-androgenic effects was not evident in outbred Wistar rats.
