ObjectiveRecurrent pregnancy loss (RPL) is a fertility problem for which no exact mechanism of abortion or efficient treatmenthas been described. This study was conducted between 2018 and 2019 to investigate the effectiveness of autologousplatelet-rich plasma (PRP) in improving the live birth rate of women with RPL who required in vitro fertilization (IVF). MethodsA total of 63 patients with at least two previous pregnancy losses and no specific cause detected for the RPL wereincluded and randomly assigned into two groups (PRP and control). Intrauterine infusion of 0.5 mL of autologous PRPwas performed 48 hours before embryo transfer in the PRP group. Women in the control group received standardtreatment. ResultsForty patients completed the study. The baseline and cycle characteristics of the participants did not differ significantlybetween the PRP and control groups. The clinical pregnancy rate was higher in the PRP group (35% vs. 20%, P=0.288). The live birth rate was 15% in the PRP group, but no live births were recorded in the control group (P=0.231). ConclusionThis is the first study to show that intrauterine infusion of PRP in patients with RPL who undergo IVF may increase thechance of live birth. 영어

Non-invasive methods are normally preferred to conventional invasive methods when selecting suitable embryos to improve pregnancy rates after assisted reproduction techniques. One of the most recognized non-invasive methods is to examine the supernatants of embryo culture media. Soluble human leukocyte antigen, class I, G (sHLA-G) antigen is a non-classical class I molecule that has been widely considered as a marker of pregnancy failure or implantation success. In the current study of some Iranian patients, we examined the concentration of sHLA-G at different time points after intracytoplasmic sperm injection and compared the rates to the morphology and quality of the selected embryos. We showed that the concentration of sHLA-G increases over time in high-quality embryos. We conclude that there is a positive relationship between morphology, quality, and sHLA-G concentration. We suggest that this relationship can be used to increase the chance of a successful pregnancy.
