Background: Granulocyte-colony stimulating factor (G-CSF) is an innovative therapy in reproductive medicine. Although its mechanisms of action have remained unknown, G-CSF seems to be effective in the case of recurrent abortion or implantation failure and thin endometrium. Objectives: This study was conducted to investigate whether subcutaneous administration of G-CSF has any effect on pregnancy outcome after assisted reproductive technology (ART). Methods: Fifty women with male infertility factors undergoing ART treatment were enrolled and stimulated with the standard long protocol. The G-CSF group of women received one dose of subcutaneous G-CSF (Filgrastim, 300 µg/1 mL) on the day of embryo transfer and again two days later while the placebo group received normal saline. Results: Seventeen patients had a positive β-human chorionic gonadotropin concentration after embryo transfer (8 and 9 in G-CSF and placebo groups, respectively) although the difference was not statistically significant. In addition, spontaneous abortion occurred in three patients (1 patient in the G-CSF group vs. 2 patients in the placebo group). Conclusion: Overall, although G-CSF failed to affect the endometrial thickness, as well as implantation, or clinical pregnancy rates, a lower prevalence of abortion in G-CSF group may be due to the positive effect of G-CSF administration on the endometrium as compared to the placebo group.

Abstract Study question Does the outcome of the first euploid frozen-thawed blastocyst embryo transfer affect the subsequent euploid FBT originating from the same cohort of oocytes? Summary answer The clinical pregnancy rate and ongoing pregnancy rate of the subsequent FBT are higher if a clinical pregnancy was attained in the first euploid FBT. What is known already Numerous factors including patient, cycle and embryological characteristics affect the outcome of an IVF treatment cycle. There is no data available whether the outcome of euploid FBT has an impact on the outcome of the subsequent euploid FBT of embryos originating from the same cohort of retrieved oocytes. Study design, size, duration The study enrolled cycles preimplantation genetic test for aneuploidy (PGT-A) performed between January 2016 and July 2019 at the Bahceci Fulya IVF Center. A total of 1051 patients with single euploid FBT were evaluated and resulted live birth (n = 589, live birth rate (LBR): 56%(589/1051)), miscarriage (n = 100, miscarriage rate (MR): 14.5% (100/689)) and no clinical pregnancy (n = 362, 34,4%, (362/1051)). 159 FBT after the first single euploid FBT originating from the same cohort of oocytes were analyzed. Participants/materials, setting, methods Second euploid FBT cycle after first FBT with a clinical pregnancy were compared to frozen-thawed cycles after a without a pregnancy. Logistic regression analysis was utilized to adjust for potential confounders including female age, body mass index, embryo quality, day of embryo frozen, number previous failed attempt, number of previous miscarriage, endometrial thickness, outcome of the first euploid FBT. Main results and the role of chance The pregnancy outcome from the first euploid FBT in the study group was resulted live birth (25.1%, (40/159)), miscarriage (15.7%, (25/159)) and no clinical pregnancy (59.1%, (94/159). The pregnancy outcome of the subsequent euploid embryo transfer from the same oocyte cohort was clinical pregnancy rate (CPR): (67.3%, (107/159) ongoing pregnancy rate (OPR) (52.2% (83/159) and MR (22.4%, (24/107)). The CPR in the subsequent euploid FBT was 80% (52/65) among patients who achieved a clinical pregnancy in the first euploid FBT and 58.5% (55/94) of those who did not (p = 0.0045). The OPR in the subsequent euploid FBT was 64.6% (42/65) among patients who achieved a clinical pregnancy in first euploid FBT and 43.6% (41/94) of those who did not (p = 0.009). On a multivariate regression analysis, clinical pregnancy in the first euploid FBT was a significant independent predictor for a pregnancy in the subsequent FBT transfer (p = 0.003). Limitations, reasons for caution The limitation of the study is in the retrospective nature of the study. As the PGT-A strategy significantly decreases number of transferable embryos, the sample size of the study is limited. Wider implications of the findings: Identifying predictive factors for the success of euploid FBT is important. These can help physicians while counseling patients regarding the outcome of the previous euploid FBT. Trial registration number NA

Abstract Study question What is the effect of endometrial compaction on live birth rate in frozen-thawed embryo transfer (FET) cycles? Summary answer In FET cycles with artificial endometrial preparation, the chance for live birth was significantly higher in cycles with endometrial compaction. What is known already Most studies conclude that thinner the endometrium poorer the pregnancy outcome. These studies mostly include measurements in the follicular phase. Since endometrial thickness indicates receptivity, one may expect the endometrial thickness measured on ET day to be more important to predict the outcome. However, few studies assessed endometrial thickness on ET day and unlike follicular phase studies conflicting results were obtained regarding pregnancy outcome. The change in endometrial thickness may be more valuable to predict the pregnancy outcome rather than a single measurement. Study design, size, duration Retrospective observational cohort study. 283 FET cycles in which all patients underwent artificial endometrial preparation were reviewed. Participants/materials, setting, methods: The inclusion criteria were artificial endometrial preparation, age between 20–38 years. The same protocol was applied to all patients for the endometrial preparation.The change of endometrial thickness between the end of estrogen phase and embryo transfer day was recorded. Any decrement is defined as endometrial compaction. The patients were grouped according to the changes of endometrial thicknesses as compaction and non-compaction. Main results and the role of chance Among 283 cycles, 89 had endometrial compaction and 194 did not have compaction. The clinical pregnancy, implantation and live birth rates were significantly higher in the compaction group when compared to non-compaction group (P values 0.007, 0.009, and 0.039, respectively). In order to evaluate the results according to the degree of compaction, we divided the patients into 5% compaction slices. The live birth rate was significantly higher in the 5–10% compaction group (P = 0.016). A multivariable logistic regression analysis was performed to examine the independent effects of different variables on live birth chance.In FET cycles with artificial endometrial preparation, the chance for live birth was significantly higher in cycles with endometrial compaction (OR: 2.352, 95% confidence interval {CI} 1.297–4.264, P = 0.005). A receiver operating characteristic (ROC) curve analysis was performed to evaluate whether there was a certain threshold of endometrial thickness at the end of estrogen phase for endometrial compaction to occur. The sensitivity and specificity of 9.25 mm at the end of estrogen phase calculated from the ROC curve were 76.4% and 58.8%, respectively (area under the curve: 0.701, 95% CI 0.640–0.763; P < 0.001). Limitations, reasons for caution The main limitations of the study were its retrospective nature, relatively small sample size and utilization of different ultrasound techniques at different measurements (using transvaginal ultrasound at the end of the estrogen phase and transabdominal ultrasound on ET day). Wider implications of the findings: Recently a cohort study they found that endometrial compaction results in better pregnancy outcomes, similar to our findings. But, this is the first study to suggest a threshold value (9.2) for endometrial thickness before the commencement of progesterone in regards to increase the chance of compaction.

Abstract Background The aim of this study was to explore the impact of endometrial thickness change after progesterone administration on pregnancy outcome in patients transferred with single frozen-thawed blastocyst. Methods This observational cohort study included a total of 3091 patients undergoing their first frozen-thawed embryo transfer (FET) cycles between April 2015 to March 2019. Endometrial thickness was measured by trans-vaginal ultrasound twice for each patient: on day of progesterone administration, and on day of embryo transfer. The change of endometrial thickness was recorded. Results Regardless of endometrial preparation protocol (estrogen-progesterone/natural cycle), female age, body mass index (BMI), and infertility diagnosis were comparable between patients with an increasing endometrium on day of embryo transfer and those without. However, clinical pregnancy rate increases with increasing ratio of endometrial thickness. Compared with patients with Non-increase endometrium, those with an increasing endometrium on day of embryo transfer resulted in significantly higher clinical pregnancy rate (56.21% vs 47.13%, P = 0.00 in estrogen-progesterone cycle; 55.15% vs 49.55%, P = 0.00 in natural cycle). Conclusions In most patients, endometrial thickness on day of embryo transfer (after progesterone administration) increased or kept being stable compared with that on day of progesterone administration. An increased endometrium after progesterone administration was associated with better pregnancy outcome.

Infertility Patients

Background: Infertility is defined as failure to conceive a clinical pregnancy after 12 months or more of regular unprotected intercourse. The birth of Louis Brown opened door to whole new world. Science of reproduction unfolded with better understanding of physiology and pharmacology of gonadotropins. Improved stimulation protocol, and lab facilities are available for IVF and intracytoplasmic sperm injection (ICSI). The objective of this study was to study relation between uterine scoring system for reproduction (USSR) scoring and pregnancy rate in patients undergoing ICSI and embryo transferred.Methods: A prospective observational study was conducted. Study comprised 48 women visiting with infertility for ICSI and embryo transfer. Baseline scan done on day2 of menses. Patients started on estradiol valerate for endometrial preparation. Transvaginal sonography done on 10th day of menstrual cycle for USSR scoring. USSR scoring includes parameters such as endometrial thickness, endometrial layering, myometrial contractions, myometrialechogenecity, uterine artery Doppler flow, endometrial blood flow, myometrial blood flow.Results: Out of total 48 infertility patients for embryo transfer 22 conceived, which gives 45.83% pregnancy rate. No patients had a perfect score of 20. Patients with score of 17-19 had pregnancy rate of 66%. Endometrial thickness of 10-14mm gave optimum result of 52%. Pulsatality index <2.19 was associated with pregnancy rate of 66%.Conclusions: USSR scoring is highly indicative of good pregnancy outcome in patients undergoing ICSI and embryo transfer. Endometrial morphology and thickness was strongly correlated with successful pregnancy outcome.
