title: An ultrasound study of the effect of chronic lead exposure on endometrial cycle changes in the female cynomolgus monkey.
abstract: The effect of up to 10 years of lead (Pb) exposure (1500 micrograms/kg BW/day) on endometrial cycle changes in adult cynomolgus monkeys (n = 30) were examined by real-time ultrasound. Pb exposure had no effect on peak serum estradiol (E2) or progesterone (P4) concentrations, menstrual cycle length, and endometrial response to gonadal steroids as determined by ultrasound.
