“…SOD activity was in FF higher than in serum [33]. In prospective cohort study by Younis et al,in patients including PCOS, endometriosis and unexplained infertility, antioxidant enzyme's activities were measured [34]. There was statistically difference between pregnancy positive group and pregnancy negative group according to serum SOD activities.…”

Purpose The Fas-Fas Ligand interaction is one of the essential events for the induction of apoptosis whereas the exact role of their soluble forms in the reproductive system is still not fully understood. Also oxidative stress in the pathogenesis of infertility causing diseases in women and has been suggested as one of the important factors that negatively affect IVF outcome. In this study, our aim was to evaluate serum and follicular fluid levels of soluble Fas soluble Fas Ligand, malondialdehyde, superoxide dismutase and total antioxidant capacity in patients undergoing IVF and compared with controls. Methods This study included 109 patients. Patients were classified as unexplained infertility (N=31), PCOS (N=19), tubal factor (N=9) and endometriosis (N=10) and compared with male factor infertility (N=40) that was the control group. sFas and sFasL levels were measured by immunoassay method. MDA, SOD and TAC levels were measured by colorimetric method. Results Patients with unexplained infertility, PCOS and tubal factor had significantly lower sFas levels compared with their controls (respectively, p<0.01, p<0.05, p<0.05). However, SOD activity in unexplained infertility, PCOS and endometriosisgroupswere significantly higher than control group (p<0.01).Decreased follicular fluid TAC levels were found in all patient groups compared with controls (respectively, p<0.01, p<0.05, p<0.01, p<0.01).Patients with tubal factor had significantly higher serum sFasL (p<0.05), but lower follicular fluid sFasL levels (p<0.05) compared with unexplained infertility. Tubal factor and endometriosis groups had lowerfollicular fluid TAC levels compared to unexplained infertility and PCOSgroups (p<0.01). Conclusion(s) In this study, serum and follicular fluid sFas levels were decreased and antioxidant activity was impaired in infertility, possibly implying increased apoptosis. Especially in unexplained infertility group changes in this parametres more remarkable.

“…Interestingly, pregnancy negative infertile woman who never conceived had lower PON activity than women who became pregnant but OH increased PON activity promoting a favorable environment for implantation [20]. Our patient exhibited a 57% reduction of PON activity partly due to her homozygous PON G192A mutation and partly to her aPL favoring infertility and her PON activity could not rise after OH because of the same reasons.…”

Ovarian hyperstimulation (OH) is not a contraindication in selected women with antiphospholipid syndrome and/or systemic lupus erythematosus (SLE). A young woman who was persistently positive antiphospholipid antibodies, low protein free S and homozygous for the paraoxonase G192A mutation underwent three courses of OH; after the fourth course she developed severe thromboembolism and clinical features of SLE despite the use of a gonadotropin-releasing hormone agonist alongside aspirin that should have minimised the risk of OH syndrome. We provide a pathogenetic interpretation of these events in the light of the patient's investigations.

“…This polymorphism also was not included in the final version of the test panel due to lack of information about its role in the development of a number of multifactorial diseases such as female infertility, metabolic syndrome, vascular disorders. It is also not described methods compensatory treatment of conditions caused by decreased activity of paraoxonase especially in IVF [87]. It is seems to be better approach the appointment of testing SNP of detoxification system genes individually to women exposed to the adverse effects of the environment, having contact with toxic substances, kept smoking.…”

Background: At present, the patient preparation for IVF needs to undergo a series of planned tests, including the genotyping of single nucleotide polymorphism (SNP) alleles of some genes. In former USSR countries, such investigation was not included in overwhelming majority of health insurance programs and paid by patient. In common, there are prerequisites to the study of more than 50 polymorphisms. An important faced task is to determine the optimal panel for SNP genotyping in terms of price/number of SNP. Materials and methods: During 2009-2015 in the University Hospital of St. Petersburg State University, blood samples were analyzed from 550 women with different reproductive system disorders preparing for IVF and 46 healthy women in control group. In total, 28 SNP were analyzed in the genes of thrombophilia factors, folic acid cycle, detoxification system, and the renin-angiotensin system. The method used was real-time PCR. Results: A significant increase in the frequency of pathological alleles of some polymorphisms in patients with habitual failure of IVF was shown, compared with the control group. As a result, two options defined panels for optimal typing SNP before IVF were composed. Standard panel includes 8 SNP, 5 in thromborhilic factors, and 3 in folic acid cycle genes. They are 20210 G4A of FII gene, R506Q G4A of FV gene (mutation Leiden), -675 5G44G of PAI-I gene, L33P T4C of ITGB3 gene, -455 G4A of FGB gene, 667 C4T of MTHFR gene, 2756 A4G of MTR gene, and 66 A4G of MTRR gene. Extended panel of 15 SNP also includes 807 C4T of ITGA2 gene, T154M C4T of GP1BA gene, second polymorphism 1298 A4C in MTHFR gene, polymorphisms of the renin-angiotensin gene AGT M235T T4C and -1166 A4C of AGTR1 gene, polymorphisms I105V A4G and A114V C4T of detoxification system gene GSTP. Conclusion:The results of SNP genotyping can be adjusted for treatment tactics and IVF, and also medical support getting pregnant. The success rate of IVF is increased as the result, especially in the group with the usual failure of IVF.
