Abstract

Background: The largest percentage of failed invitro fertilization (IVF) cycles, are due to lack of implantation. As hereditary thrombophilia can cause in placentation failure, it may have a role in recurrent IVF failure.
Objective: Aim of this case-control study was to determine whether hereditary thrombophilia is more prevalent in women with recurrent IVF failures.
Materials and Methods: Case group comprised 96 infertile women, with a history of recurrent IVF failure. Control group was comprised of 95 healthy women with proven fertility who had conceived spontaneously. All participants were assessed for the presence of inherited thrombophilias including: factor V Leiden, methilen tetrahydrofolate reductase (MTHFR) mutation, prothrombin mutation, homocystein level, protein S and C deficiency, antithrombin III (AT-III) deficiency and plasminogen activator inhibitor-1 (PAI-1) mutation. Presence of thrombophilia was compared between groups.
Results: Having at least one thrombophilia known as a risk factor for recurrent IVF failure (95% CI=1.74-5.70, OR=3.15, p=0.00). Mutation of factor V Leiden (95% CI=1.26-10.27, OR=3.06, P=0.01) and homozygote form of MTHFR mutation (95% CI=1.55-97.86, OR=12.33, p=0.05) were also risk factors for recurrent IVF failure. However, we could not find significant difference in other inherited thrombophilia’s.
Conclusion: Inherited thrombophilia is more prevalent in women with recurrent IVF failure compared with healthy women. Having at least one thrombophilia, mutation of factor V Leiden and homozygote form of MTHFR mutation were risk factors for recurrent IVF failure.

Abstract

Background: Implantation failure of blastocyst is one of the main reasons of failure to become pregnancy following use of Assisted Reproductive Techniques. HLA-G, one of the non-classic HLA subtypes, seems to have a vital role in neutralizing of mother immune system. According to importance of ins/del polymorphism of HLA-G in regulation of HLA-G expression, it seems that this polymorphism has an important effect in immune response against embryo, and so success of embryo implantation.
Objective: In this experiment we try to evaluate association of HLA-G ins/del polymorphism with risk of occurrence of RIF in ART treated infertile women.
Materials and Methods: To evaluating insertion/deletion polymorphism association with RIF we design a case-control study. We select 40 women with history of recurrent failure to become pregnant following IVF as RIF case group. Forty women with pregnancy following IVF were selected as control. Members of both groups were assessed to rule out of anatomical, immunological and known genetical cause of infertility. Presence of 14 bp insertion/deletion alleles was assessed using PCR-PAGE technique. The data were analyzed by means of SPSS software using Chi-Square tests at the significant level of p<0.05.
Results: Our data shows that frequency of heterozygote genotype (ins/del) was significantly higher in case group. Furthermore presence of HLA-G insertion/deletion genotype shows association with increase of implantation failure risk by 3.85 fold.
Conclusion: According our results, Heterozygote genotype of ins/del leads to increase of RIF risk. It seems that by genotyping of HLA-G polymorphism, we can predict risk of implantation failure in infertile women after use of ART.

Abstract

Background: Platelets contain a significant amount of growth factors that have positive effects on local tissue repair and endometrial receptivity.
Case: Here we present a 45-yr-old woman with primary infertility and two failed in vitro fertilization (IVF) cycles who was candidate to receive donor eggs. Five consecutive frozen-thawed embryo transfer cycles with good quality embryos were performed within 2 yr. With the diagnosis of recurrent implantation failure (RIF), the patient was treated for improving endometrial receptivity with intrauterine administration of autologous platelet-rich plasma (PRP), 24 hr before embryo transfer. The patient gave birth to a healthy baby boy weighing 2350 gr in the cesarean section.
Conclusion: Extensive literature search suggests that this is the first successful pregnancy after administration of PRP in a woman with RIF. Local administration of PRP before embryo transfer may play a vital role in successful implantation
