Pregnant rats were exposed to endosulfan (1 or 2 mg/kg per day) from day 12
of gestation through parturition. Male neonates were fostered to untreated
darns. At 100 days of age, the male offspring were sacrificed. Exposure to
endosulfan during fetal gonadal differentiation altered the process of spe
rmatogenesis by affecting testicular lactate dehydrogenase and sorbitol deh
ydrogenase. Reduction in spermatid count in testis and sperm count in cauda
epididymis was observed. Testis, epididymis and seminal vesicle showed sig
nificant decrease in weights in both the treated groups while no effect on
prostate weight was recorded. Hence it can be suggested that endosulfan int
erferes in the process of spermatogenesis. The overall toxicity was dose de
pendent. (C) 2001 Elsevier Science B.V. All rights reserved.
