Abstract

 Introduction: Infertility is defined as the inability to conceive after 1 year of unprotected sexual intercourse. In 40% of infertile couples, a male factor is involved. A probable cause of male infertility is leukocytospermia, which may be associated with poor sperm parameters. This study was carried out to determine ferquency of leukocytospermia, and evaluate its correlation with sperm concentration, motility and morphology in infertile men.Materials and Methods: We retrospectively reviewed semen analysis of 150 infertile men referred to Kashan's Infertility Center during 2007- 2008. Frequency of leukocytospermia (semen WBC>0.25x106/m1) and its correlation with sperm concentration, morohology and motility was investigated. Seminal WBC concentration was determined by peroxidase method. Samples were grouped as with and without leukocytospermia based on WBC >0.25x106 threshold. Sperm parameters as well as age, job and rate of smoking were compared in these two groups by Chi-square, Fisher’s analysis and t-test.Results: Mean age of these 150 infertile men was 28. 126 patients (84%) were nonsmokers. 33 patients (22%) had leukocytospermia. Leukocytospermia was not correlated with age or smoking. In leukocytospermia patients, 29 (88%) had sperm concentration >20x106; 21(64%) had sperm motility>50%, and 5 (15%) had sperm morphology >40%. In nonleukocytospermic patients, 100 (85%) had sperm concentration >20*106; 105 (90%) had sperm motility >50%, and 13 (11%) had sperm morphology >40%. Leukocytospermia was not correlated with sperm concentration or morphology (P»1.00, P=0.743, respectively); but significantly correlated with motility (p=0.001).Conclusion: With respect to correlation of leukocytospermia with sperm motility, and important role of sperm motility in fertilization, we can conclude that detection and treatment of leukocytospermia, after excluding genitourinary infection, may have positive influence on fertility and pregnancy rates in infertile couples.
