RESULTS: Sixty-three percent placebo-treated subjects developed >18 mm, 39% 23% groups. The risks for each group developing large follicle single cycle were not different. No dominant persisted >2 weeks any subject. CONCLUSION: These results demonstrate follicular continues treatment contraceptives. In addition, findings fail support result
