  Purpose: To evaluate the levels of DNA fragmentation regarding to spermatozoa morphology in male infertility patients attending Andrology Laboratory at fertility center.  Methods: Semen samples of 196 patients were analyzed using computer-assisted semen analysis (CASA). Sperm DNA fragmentation was measured by the sperm chromatin dispersion test. According to the values of sperm morphology, the groups were conformed by teratozoospermic (105 patients) and normozoospermic (91 patients) men.  Results: Subjects’ ages ranged from 21 to 68 years. Teratozoospermic men were older that the normozoospermic men (39.72 ± 7.86 vs. 36.57 ± 6.29 years; P<0.05). Values of pH were similar in both evaluated groups (P:NS). Parameters of volume, concentration, motility and vitality in teratozoospermic men were significantly lower compared .. View More»
