RESUMEN
The urogenital inflammations may be considered as "apparatus pathology". We analyze only inflammatory diseases of the prostate gland, because it may be extensible to the entire male genital apparatus. Among aethiological agents of infections an important role belongs to Chlamydia and Mycoplasma; we describe various methods for diagnosis of the Chlamydia and Mycoplasma infections. When objective clinical findings are poor or absent (such in prostatosis and prostatodynia) the transrectal ultrasonography demonstrates characteristic pictures useful for diagnosis and follow-up. Our clinical data and anatomo-pathological remarks suggest a real correlation between varicocele and genital inflammations (26%). This association doesn't represent the only cause of infertility, but frequently reduces the probability of male fertility.
