HOXA11 and polycystic ovary syndrome: When Hoxa11 gene expression is suppressed, this formula can reverse the consequent decline in receptivity-related gene expression.<h4>Conclusions</h4>QGW is capable of enhancing the expression of genes related to endometrial receptivity in PCOS model rats and increasing the number of pinopodes, thereby improving the endometrial receptivity in PCOS rats.
