**3. Prevalence of infection in infertile males.**

Infections of male genital urinary tract account for about 15% of the case of male infertility. Different sites can be affected in the male reproductive system, such as the testis, epididymis, and male accessory sex glands. Spermatogenesis itself can be affected by urogenital infections at different levels of development, maturation, and transport of spermatozoa [3].

Leucocytospermia has been reported among 10–20% of infertile male patients. Twenty-five percent of patients with abnormal semen function have been proved to have antibodies to *C. trachomatis* [5–9, 20].
