Fecal hormone metabolites during the estrous cycle of female giant anteaters. Mean weekly concentrations of fecal P4 and E1 metabolites during the estrous cycles: (A) a multiparous female (Monita: n = 6 cycles), and (B) two nulliparous females (Emelia and Lia: n = 6 cycles). Data are reported as mean ± SEM each week relative to the peak E1 concentration during estrus. Note the shorter estrous cycle length (B, mean, 47 days) and the three-fold lower concentrations of P4 metabolites in the nulliparous females relative to the multiparous female (A, mean estrous cycle length, 62 days).
