Abstract We have studied the oxidative status of 155 semen samples, 95 originating from healthy individuals and 60 from infertile patients, which were subdivided into two groups: (a) normozoospermic with genitourinary tract infection (GTI); and (b) with pathological spermiogram and GTI. Several phases of infection were observed: with bacterial presence only, bacteria and leukocytes, and leukocytes only, following the routine inflammatory pattern. Leukocyte numbers, bacterial strains, pro- and anti-oxidants, and selected pro-inflammatory cytokines (IL-1 beta, IL-6, IL-8 and TNF-alpha) were studied. Additionally, two oxido-sensitive indices were created (SOD/XO and CAT/XO) in order to follow particular phases of semen infection in two subgroups of patients. Different patterns of activities of pro- and anti-oxidant substances, as well as cytokines, were observed in the studied populations. It was reflected mainly by elevated XO activity in a group of patients with a pathological spermiogram while, in a group of patients with GTI and normozoospermia, xanthine oxidase was normal. In the latter group, oxido-sensitive indices were elevated in favour of anti-oxidants; similarly, this occurred with IL-6 levels in comparison to healthy controls. It appears therefore that normozoospermic semen recovers better after infection than pathological semen. Perhaps, IL-6 secretion might be helpful in the observed recovery?
