The role of asymptomatic infections caused by Chlamydia trachomatis in male infertility and the efficacy of antibiotics in the treatment of this condition are not yet definitely determined. A total of 165 infertile males having abnormal semen parameters (study group) as well as 165 healthy fertile men (control group) were included. Semen samples were taken from all participants and after analysing for semen parameters, undergone real‐time PCR, and reactive oxygen species (ROS) as well as total antioxidant capacity (TAC) assays. Infected individuals of study group were treated with antibiotic. One month after the treatment completion, second semen samples were taken and undergone all the tests mentioned. The frequency of C. trachomatis was significantly higher in the infertile men compared with the fertile ones (4.2% vs 0.6%). Most of the semen parameters were improved and reached their normal range, the level of TAC elevated and ROS level as well as ROS/TAC ratio reduced after antibiotic treatment. Moreover, wives of three infected infertile men (42.9%) became pregnant 4 months after the treatment completion. Our data suggest that asymptomatic infection caused by C. trachomatis is correlated with male infertility and antibiotic therapy can improve the semen quality and fairly treat the male infertility.
