Endocrine effects of chlorinated hydrocarbons in rhesus monkeys.
Ecotoxicol. Environ. Saf. 2, 161-172 (1978)
After the rhesus monkey was demonstrated to be a suitable model for man in both metabolic and endocrinological studies, effects of hexachlorobenzene (HCB) and polychlorinated biphenyls (PCB) on the pattern of sexual hormones in cycling female rhesus monkeys were investigated. After confirmed ovulation, four adult female rhesus monkeys were treated during the following cycle with 4 mg/kg/day of HCB, and four other monkeys were treated with the same dose of Clophen A 30. Ovulation was blocked in three PCB-treated and one HCB-treated monkeys. Whereas the levels of luteinizing hormone and follicle-stimulating hormone did not seem to be changed directly by the treatment, low estrogen levels were found during the anovulatory cycles. Studies with PCB- and HCB-treated superovulated rats indicated interaction of the chemicals with ovarian steroidogenesis. Altered hepatic steroid metabolism may also cause low estrogen levels in treated animals.
