Fig. 2From: Effect and mechanisms of reproductive tract infection on oxidative stress parameters, sperm DNA fragmentation, and semen quality in infertile malesOrdinary optics microscope images of sperm in SCD test (Switzer land staining 10 × 20). 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
