Title

Evaluation of intracellular anion superoxide level, heat shock protein A2 and protamine positive spermatozoa percentages in teratoasthenozoospermia

Pages

Abstract

 Background: Teratoasthenozoospermia (TA) is a severe form of Male infertility with no clear etiology. Objective: To compare the level of intracellular anion superoxide (O2– ), heat shock protein A2 (HSPA2) and protamine deficiencies in ejaculated spermatozoa between teratoasthenozoospermic and normozoospermic men. Materials and Methods: In this case-control study, semen samples of 20 infertile men, with TA (with normal morphology lower than 4%_ and total motility lower than 40% ) as the case group and 20 normozoospermic fertile men as the control group were evaluated for intracellular O2 – and HSPA2 by flow cytometry and Protamine deficiency by Chromomycin A3 (CMA3) test. Results: The rate of CMA3+ spermatozoa in the case group was higher than controls (p=0. 001). The percentages of HSPA2+ spermatozoa in the cases were significantly lower than controls (p=0. 001). Also, intracellular O2 – levels in the case group were significantly higher than controls (p=0. 001) and had positive correlations with sperm apoptosis (r=0. 79, p=0. 01) and CMA3 positive sperm (r=0. 76, p=0. 01), but negative correlations with normal morphology (r=-0. 81, p=0. 01) and motility (r=-0. 81, p=0. 01). There was no significant correlation between intracellular O2 – and HSPA2 in the case group (r=0. 041, p=0. 79). Conclusion: We suggest that the increase in intracellular O2 – , decrease in spermatozoa HSPA2+, and high percentages of spermatozoa with immature chromatin might be considered as etiologies of infertility in TA patients.
