Abstract
Introduction Fetal health and a receptive and healthy endometrium are two essential factors in achieving successful implantation. If the endometrium is unreceptive, postponing the transfer cycle to a suitable time can enhance the chances of pregnancy. This study aims to assess the impact of endometrial and sub-endometrial blood flows measured by Doppler ultrasound, as well as endometrial volume, on endometrial receptivity in frozen embryo transfer (FET) cycles. Methods 112 patients with a mean age of 33.93 ± 4.93 years underwent in vitro fertilization (IVF). Serum β-hCG level was used to confirm pregnancy, and among the participants, 50 (44.6%) achieved pregnancy after IVF. Results The study results revealed a significant difference in endometrial blood flow between the pregnant and non-pregnant groups, with a higher pregnancy rate observed in participants exhibiting multi-focal and spare endometrial blood flows (p < 0.05). Furthermore, there was a notable association between endometrial blood flow and pregnancy outcome, as indicated by higher ongoing pregnancy rates in those with multi-focal and spare endometrial blood flows (p < 0.05). However, no significant differences were observed in endometrial variables such as volume, length, width, thickness, and pattern between the pregnant and non-pregnant groups. Additionally, contextual parameters showed no significant relationship with pregnancy outcome (p > 0.05). The study also found that endometrial measurement indices did not have a significant impact on pregnancy outcomes, with no significant differences observed between the groups (p > 0.05). Conclusion In conclusion, endometrial blood flow is crucial for a successful pregnancy after IVF, while the predictive value of the endometrial volume is limited for pregnancy outcomes.

Abstract
Embryos of optimal development reach blastocyst stage 116 ± 2 h after insemination. Usable D7 blastocysts represent nearly 5% of embryos in IVF with acceptable pregnancy and live birth rates, however data are still limited. Therefore, this study aimed to analyze the ongoing pregnancy rate (OPR) of D7 blastocysts in single euploid frozen embryo transfer (FET) cycles. An observational study was performed including 1527 FET cycles with blastocysts biopsied on D5 (N = 855), D6 (N = 636) and D7 (N = 36). Blastocysts were classified as good (AA/AB/BA), fair (BB) or poor (AC/BC/CC/CA/CB) (Gardner scoring). FETs were performed in natural cycles (NC) or hormone replacement therapy (HRT) cycles. Patient's age differed significantly between D5, D6 and D7 blastocysts FET cycles (33.2 ± 5.6, 34.4 ± 5.3 and 35.9 ± 5.2, P < 0.001). OPRs were higher when D5 euploid blastocysts were transferred compared with D6 and D7 (56.0% vs. 45.3% and 11.1%, P < 0.001). Poor quality blastocysts were predominant in D7 blastocyst FET cycles (good quality: 35.4%, 27.2%, 5.6%; fair quality: 52.1%, 38.5%, 11.1%; poor quality: 12.5%, 34.3%, 83.3%, P < 0.001 for D5, D6 and D7 blastocysts; respectively). OPR was significantly reduced by D7 blastocyst FETs (OR = 0.23 [0.08;0.62], P = 0.004), patient's BMI (OR = 0.96 [0.94;0.98], P < 0.001), HRT cycles (OR = 0.70 [0.56;0.88], P = 0.002) and poor quality blastocysts (OR = 0.33 [0.24;0.45], P < 0.001). OPR is significantly reduced with D7 compared with D5/D6 euploid blastocysts in FET cycles. The older the patient, the more likely they are to have an FET cycle with blastocysts biopsied on D7, therefore culturing embryos until D7 can be a strategy to increase OPR outcomes in patients ≥38 years.

Abstract
RESEARCH QUESTION What is the discontinuation rate among patients with remaining cryopreserved embryos in Belgium and what are the reasons for discontinuation? DESIGN Multicentre, cross-sectional study across 11 Belgian fertility clinics. Patients were eligible (n = 1917) if they had previously undergone an unsuccessful fresh embryo transfer (fresh group) or frozen embryo transfer (FET) (in-between group) and did not start a subsequent FET cycle within 1 year despite having remaining cryopreserved embryos. The denominator was all patients with embryos cryopreserved during the same period (2012-2017) (n = 21,329). Data were collected through an online anonymous questionnaire. RESULTS The discontinuation rate for patients with remaining cryopreserved embryos was 9% (1917/21329). For the final analysis, 304 completed questionnaires were included. The most important reasons for discontinuing FET cycles were psychological (50%) and physical (43%) burden, effect on work (29%), woman's age (25%) and effect on the relationship (25%). In 69% of cases, the patient themselves made the decision to delay FET treatment. In 16% of respondents, the decision to delay FET was determined by external factors: treating physician (9%), social environment (4%), close family (3%) and society (3%). Suggested improvements were psychological support before (41%), during (51%) and after (51%) treatment, as well as lifestyle counselling (44%) and receiving digital information (43%). CONCLUSIONS The discontinuation rate is remarkably high in patients with remaining cryopreserved embryos who have a good prognosis. Respondents stressed the need to improve the integration of psychological and patient-tailored care into daily assisted reproductive technology practice.

Abstract
Objective The objective of this prospective study is to compare the prevalence and severity of nausea and vomiting in the first trimester between singleton pregnancies conceived from stimulated in vitro fertilization (IVF) and frozen embryo transfer cycles (FET). Methods All women were recruited at 6 weeks gestation and filled in the modified Pregnancy-Unique Quantification of Emesis and Nausea (PUQE) to document whether they had any experience of nausea and vomiting weekly till 12 weeks gestation. The primary outcome was the prevalence of nausea and vomiting and the secondary outcomes included severity of nausea and vomiting and pregnancy outcomes. Results A total of 360 pregnant women were recruited and 171 were in the stimulated IVF group and 189 in the FET group. The overall return rate was 82.2% (81.8% in the stimulated IVF group and 82.5% in the FET group). Nausea and vomiting were worse in the FET group compared with the IVF group. There were significantly more women who felt nauseated or sick in the FET group (p value = 0.032 for week 11 and p value = 0.046 for week 12); significantly more women with a longer duration of nausea in the FET group (p value = 0.044 for week 7 and p value = 0.030 for week 8); significantly more women with more vomiting in a day in the FET group (p value = 0.042) and significantly more women with retching or dry heaves in the FET group (p value = 0.030 for week 8 and p value = 0.028 for week 11). Conclusion Nausea and vomiting were significantly more prevalent and severe in the FET group when compared with the stimulated IVF group.

Abstract
RESEARCH QUESTION What are the effects on pregnancy outcome in patients with polycystic ovary syndrome (PCOS) in endometrial preparation cycles for vitrified-warmed embryo transfer with or without gonadotrophin releasing hormone (GnRH) agonist pre-treatment? DESIGN A total of 212 patients with PCOS referred to Royan Institute, Tehran, Iran, between 20 August 2017 to 20 June 2018 were included. The patients were randomly assigned to receive oestradiol after downregulation with GnRH agonist (group A) or without GnRH agonist down-regulation (group B). RESULTS A total of 188 patients with PCOS completed the trial, 93 patients in group A and 95 patients in group B. Basal oestradiol and LH levels were significantly higher in group B (26.66 versus 41.61, P = 0.01 and 0.93 versus 5.33, P < 0.0001, respectively). Clinical pregnancy rates were not significantly different in both groups (31.2% versus 33.7%). Similarly, no significant differences were found between groups A and B in miscarriage (9.7% versus 11.6%), implantation (0.58 versus 0.51) and live birth (21.7% versus 22.1%) rates and for medical complications during pregnancy and neonatal anomalies. CONCLUSIONS Our findings indicate that endometrial preparation for frozen-thawed embryo transfer with and without ovarian suppression by GnRH agonist provides similar results.

Abstract
PURPOSE OF THE STUDY To study the role of endometrial and subendometrial blood flow measured by 3D power Doppler as predictors of pregnancy in frozen embryo transfer (FET) cycles. METHODS A hospital-based prospective study of two hundred and twenty-one (221) women undergoing FET cycles with a triple-line endometrium ≥7 mm on day 14 endometrial and subendometrial blood flow was assessed using 3D power Doppler, and various indices endometrial volume, subendometrial volume and their vascularisation index (VI), flow index (FI) and vascularisation flow index (VFI) were obtained and compared between the pregnant and the non-pregnant group. Primary outcome was clinical pregnancy. RESULTS Out of 221 women, 97(43.89 %) became pregnant, while 124 (56.10 %) failed to become pregnant. The endometrial volume was comparable between the two groups. Endometrial VI, FI and VFI were significantly higher in the pregnant as compared to the non-pregnant group. There was a significant difference in subendometrial VI and VFI between the two groups, but FI was similar. CONCLUSIONS Endometrial and subendometrial vascularity by 3D power Doppler can be a useful parameter in predicting pregnancy in FET cycles.
