Wg. Foster et al., AN ULTRASOUND STUDY OF THE EFFECT OF CHRONIC LEAD-EXPOSURE ON ENDOMETRIAL CYCLE CHANGES IN THE FEMALE CYNOMOLGUS MONKEY, Journal of medical primatology, 21(7-8), 1992, pp. 353-356
The effect of up to 10 years of lead (Pb) exposure (1500 mug/kg BW/day
) on endometrial cycle changes in adult cynomolgus monkeys (n = 30) we
re examined by real-time ultrasound. Pb exposure had no effect on peak
serum estradiol (E2) or progesterone (P4) concentrations, menstrual c
ycle length, and endometrial response to gonadal steroids as determine
d by ultrasound.
