Successful implantation requires endometrial receptivity. To investigate the mechanisms of miR-494-3p on receptivity, GnRHa's superovulation scheme was designed to reduce and pregnant mice were injected with antagomir. The regulatory role identified by RT-qPCR, uterine blastocyst count, scanning electron microscopy, hematoxylin-eosin (HE) staining, Western blot. Results indicated that antagomir...
