Influence of TEAS on endometrial pinopode development in women on the theoretical embryo implantation day. Photograph A showing pinopodes in scanning electron microscopy. Histogram B showing that the mean number of pinopodes seen per high-power field was higher in the TEAS group than in the control group (*P < 0.05, two-tailed Student’s t-test). Linear regression analysis C showed that the serum progesterone levels were positively correlated with the number of endometrial pinopodes
