BRD2 and varicocele: Among them, the increase in the testicular volume (ΔTV) in the >35-year-old group was greater than that in the ≤35-year-old group (Figure 3B), but there were only significant differences in the increase in the left testicular volume (ΔL-TV) (p < 0.05) (Figure 3B), and the increase in the width of the varicocele vein (ΔVW) was less than that in the ≤35-year-old group (p < 0.05) (Figure 3C), while the decrease degree of FSH (ΔFSH) was greater than that in the ≤35-year-old group (p < 0.05), and the increase in neutral α-glucosidase (ΔNeu) was less (p < 0.05) (Figure 3D).
