Serum estrogen (dotted line) and progesterone (solid line) values obtained from an animal treated with ORG 9935 200 mg/kg/day throughout the follicular phase (cycle days 2-13). A biphasic pattern of estrogen followed by progesterone secretion is seen, suggesting ovulation. Samples were not collected days 18 and 19.
