  1. Data are means ± s.e.m. with n = 15 per group. P-values were analyzed with Student’s t-test (nonparametric test, two tailed), **P < 0.01. Expect dominant follicle/freshly ovulated follicle with Fisher’s exact test. Max, maximum value; Min, minimum value; ET, embryo transfer; E2, estradiol; P4, progesterone; E/M = endometrial to myometrial thicknesses.
