Table 2 Uterine angles during the menstrual cycle (Prospective Study). This prospective study included patients in the FET cycle (n = 192). The uterine angles during the menstrual, ovulatory, and implantation periods are shown. Data are presented as mean ± standard deviation. P-values were assessed using Wilcoxon’s rank-sum test (*p < 0.05).
