Fig. 3From: Effect and mechanisms of reproductive tract infection on oxidative stress parameters, sperm DNA fragmentation, and semen quality in infertile malesSCD test, AO staining for fluorescence microscopy (AO staining 10 × 40). A Sterile patients with mycoplasma infection; B Males with normal fertility. a. large-size dispersion halos; b. medium-size dispersion halos; c. small-size dispersion halos; d. no dispersion halo. The percentages of sperm small-size dispersion halos and no dispersion halo were significantly higher in Group A than those in Group B. On the contrary, the percentage of sperm with large-size dispersion halos was significantly lower in Group A than that in Group B (P < 0.05)Back to article page
