Sperm morphology of the secretome-treated group (eosin and nigrosin stain; 500× magnification). No abnormal sperm morphology was observed in the control group (1), low-dose group (2), and high-dose group (3) 1 week after the first (A) and third (B) secretome injections. The head (black arrow) and tail (red arrow) of the sperm showed the normal morphology.
