An overview of the role of bacterial infection in male infertility

Abstract

An important cause of male infertility is the bacterial infections of the genitourinary tract. These infections affect sperm cell function and whole spermatogenesis and also cause deterioration in spermatogenesis, obstruction of the seminal tract, and impairment of spermatozoa function. The most important bacteria associated with genitourinary tract infections include chlamydia trachomatis, Neisseria gonorrhoeae, and genital mycoplasma species. Inappropriate or delayed therapy of the bacterial infections of the genitourinary tract will lead to reduced fertility and, subsequently in severe cases, infertility. In other words, a good understanding of the interaction between bacterial infections and the reproductive system plays an important role in the treatment of infertile men. In this review article, we will discuss clinical and laboratory findings related to the bacterial infection of the genitourinary tract and its effects on male infertility.
