Value of endometrial peristalsis analysis technique in detecting and analyzing endometrial peristalsis features

Table 1 The basic information of the patients and the comparison in patients with endometrial peristalsis, no endometrial peristalsis and endometrial peristalsis analysis done unsuccessfully
