RESUMO
AIM: To characterize the effect of the Speroton complex on the free radical homeostasis in the ejaculate of males of infertile couples and the likelihood of pregnancy in partners. MATERIALS AND METHODS: The study group comprised 30 men aged between 26 and 43 years (mean 33 +/- 4.8 years) with idiopathic infertility. All patients received Speroton one sachet once daily during meals for 3 months. The comparison group consisted of 29 men of fertile age having 1 to 3 healthy children. In infertile men, standard semen parameters including the ejaculate volume, sperm concentration, total count and proportion of abnormal forms were within the normal range. Markers of oxidative damage to ejaculate macromolecules were determined using standard diagnostic testing systems. RESULTS: The patients with idiopathic infertility were found to have statistically significant changes in the degree of chemical modification of ejaculate biopolymers. The level of lipid hydroperoxides in infertile men was significantly higher than in fertile participants. Taking Speroton resulted in the decrease of lipid hydroperoxides to the level that did not differ from that in the control group. Using Speroton was also accompanied by a decrease in the level of the oxidative damage DNA biomarker 8-oxodGu and a tendency toward normalization of the carbonyl modification of the ejaculate proteins. Five married couples in the treatment group reported achieving pregnancy. CONCLUSION: Taking Speroton was associated with the normalization of the balance of pro- and antioxidant processes in the ejaculate, as indicated by a decrease in the oxidative destruction of sperm biopolymers. The revealed molecular mechanism of the drug action is the basis for restoring the fertilizing ability and increasing the likelihood of pregnancy. The treatment effectiveness was 16.7%. Speroton is a promising drug that improves the functional sperm characteristics and contributes to achieving pregnancy in couples with a male infertility factor.
