Permanent induction of morphological abnormalities in the penis and penile skeletal muscles in adult rats treated neonatally with diethylstilbestrol or estradiol valerate: a dose-response study.

This study evaluated the effects of neonatal exposure to different doses of diethylstilbestrol (DES) or estradiol valerate (EV) on penile morphology, penile skeletal muscles, and fertility. Male pups received DES or EV at a dose of 10 microg, 1 microg, 100 ng, 10 ng, or 1 ng per rat on alternate days from postnatal days 2-12. Fertility was tested at 120… (More)
