The article presents the results of urological examination (spermograms and data of ultrasound examination) of 22 patients with chronic brucellosis and diseases of the scrotum (6 patients with orchitis, 16 with orchiepididymitis) before and after conventional therapy (10 patients) and combined treatment with the inclusion of cycloferon (2 courses of 5 intramuscular injection [0.25 g] with an interval of 10 days)--12 patients. It is shown that the administration of cycloferon leads to more effective relief of intoxication symptoms and inflammation in the testes and appendages (reduction of scrotal wall thickness, size of testes and/or adjuncts, and the incidence and severity of hydrocele), and has a positive effect on spermatogenesis (reduction of semen viscosity, the number of white blood cells in semen, sperm agglutination associated with the formation of sperm antibodies in most patients after treatment), as well as reduces the number of exacerbations of chronic orchitis/orchiepididymitis by 2.4 times.
