Figure 8. Animal experiment validation in epididymis (NOA: irradiation-induced non-obstructive azoospermia mice, Control: control group): Relative mRNA expression of signature genes (C12orf54, TSSK6, OR2H1, FER1L5, C9orf153) in epididymis. (*indicates P < 0.05, **indicates P < 0.01, ***indicates P < 0.001).
