Vimentin immunoreactivity after secretome injection (immunohistochemistry; 500× magnification). In the low-dose group (A1), 1 week after the first secretome injection, a strong vimentin immunoreactivity was observed in the spermatozoa (yellow arrow) and Sertoli cells (blue arrow), whereas in the high-dose (A2) group, the immunoreactivity was moderate. In the low-dose group (B1), 1 week after the second secretome injection, a strong vimentin immunoreactivity was still observed in the spermatozoa and Sertoli cells. Meanwhile, in the high-dose group (B2), the immunoreactivity was very strong in the same cell. In the low-dose group (C1), 1 week after the third secretome injection, moderate vimentin immunoreactivity was observed in the spermatozoa and Sertoli cells, whereas in the high-dose group (C2), the immunoreactivity was strong in the same cells. Then, 1 week after the last injection in the high-dose group (D1), the vimentin immunoreactivity was moderate in the spermatozoa and Sertoli cells. Spermatogonia (red arrow), primary spermatocytes (green arrow), and Leydig cells (white arrow).
