Comparison of progesterone (A) and estradiol (B) fluctuations through the menstrual cycle of rhesus and pigtail macaques. The first day of the menses was considered day 0. Open bars represent progesterone means of 12 PT and filled bars 12 RM +/- standard deviation of the means measured throughout the cycle. Also note progesterone levels (A), consistently rose through the cycle peaking at day 21 in both macaques. Significant differences were detected between day 0 and 21 for both species (P<0.02 PT; P<0.01 RM). Also RM have significantly higher progesterone levels on day 14 than on day 0 (P= 0.048). (B) Peak estradiol levels in both macaques were on day 14 with significant differences between day 0 and day 14 for PT (P=0.043), and day 14 and 21 for RM (P= 0.027). Significant differences in progesterone levels of RM were limited to between day 0 and day 7(P=0.046) and day14 and 21(P= 0.0028).
