Fertility and sterility
Oral contraceptives were administered cyclically to 96 female rhesus monkeys for 5 years. Forty-eight animals received Enovid-E and 48 were treated with Ovulen at doses 1, 10, and 50 times the human dose. Ophthalmic lesions did not occur at any of the dose levels employed. Significant fundic lesions, including papilledema, venous dilatation, venous retinal thrombosis, or arterial retinal thrombosis, did not develop in any of the treated animals.
