Change in estradiol, FSH and LH over the observation interval. a Mean changes in E2 concentration over the observation interval in the treatment groups (day 1 = day of treatment). b Mean changes in FSH concentration over the observation interval (day 1 = day of treatment) in the treatment groups. c Mean changes in LH concentration over the observation interval (day 1 = day of treatment) in the treatment groups. Differences among treatment groups are identified within days (P < 0.05). * Within day comparisons among experimental groups. N = 10 for 12 mm, 18 mm and post-OV groups
