Aim. To asses an effectiveness of assisted reproductive technologies (ART) program given characteristics of the cytokine profile of seminal plasma (SP) entering the female reproductive tract during sexual intercourse. Outcomes and methods. 33 married couples who applied for a treatment of infertility by means of in vitro fertilization /ICSI (Intracytoplasmic Sperm Injection) were included in the prospective study. Patients were recommended to have sexual intercourse with no restrictions during treatment and to have the last sexual intercourse 3 days before an intended transvaginal puncture (ITP). Testing of cytokines (transforming growth factor (TGF)-b1, interferon (IFN)-g, interleukin (IL)-33, IL-6, IL-8, IL-23, IL-10, tumor necrosis factor (TNF)-a, IL-18, IL- 17A, IFN-a, IL-12, monocyte chemotactic protein-1) levels in samples of partners’ SP obtained on the day having ITP were carried out using multiplex analysis with LegendPlex kits (BioLegend, USA). Results. When comparing a cytokine profile of SP in couples who did not become pregnant (n=25) and couples who become pregnant (n=8) increased IL-18 and reduced IL-10 levels (p=0,017 and p=0, 01 respectively) were revealed in the group which got pregnant. To assess a clinical relevance of cytokine content in SP ROC (Receiver Operating Characteristics) curve was used. It was established that determining of IL-18 concentration in SP has the greatest diagnostic significance (the area under a curve was 0.792±0.107, test sensitivity - 62.5%, test specificity - 95.24% at threshold concentration>210.43 pg/ml). Incidence of pregnancy at IL-18 concentration above threshold levels was 83,3% while at lower concentrations of IL-18 pregnancy occurred only in 13.0% of women. Conclusions. Elevated IL-18 levels and decreased IL-10 levels in SP of female patients’ partners who don’t have restriction of sexual life when treating infertility with ART are favorable factors for a pregnancy to occur.
