Abstract

Background: Male infertility is a common and complex problem and, despite much research in this field, the major cause of infertility unfortunately remains unknown. Genital infection and varicocele are important causes of infertility.

Aims: To compare the influence of genital infection and varicocele individually on male infertility based on semen analysis.

Study Design: Cross-sectional study.

Methods: The study included 120 infertile patients divided into two groups according to the presence of genital infection or varicocele. The first group included 60 examinees with proven genital infection, but without varicocele formation. The second included 60 patients with varicocele, regardless of the varicocele grade, but without genital infection. The fertile parameters were compared and an assessment was performed on the impact on quality of spermatogenesis due to infection and varicocele.

Results: There is a statistically significant difference regarding abnormal forms of spermatozoids (45.94±9.79 vs. 25.27±6.54) and progressive motility (8.15±1.24 vs. 24.95±7.2), between two groups of patients. However, acidity of ejaculates, minimum sperm concentration, total spermatozoid motility and ejaculate volume showed no statistically significant difference.

Conclusion: The study showed a stronger negative influence of genital infection on fertile parameters over varicocele. The significance of our study is the lack of contemporary researches comparing varicocele and genital infection influence on male infertility individually.
