Abstract Purpose: This study aimed to investigate the effect of prophylactic uterine artery embolisation (UAE) on reproductive outcomes in caesarean scar pregnancy (CSP) patients.Methods: Clinical data of CSP patients diagnosed at Shengjing Hospital of China Medical University from January 2014 to December 2019 were collected. According to inclusion and exclusion criteria, 181 patients with reproductive needs were selected and divided into UAE group (n = 51) and non-UAE group (n = 130) according to whether the patient received preventive UAE before their hysteroscopic or laparoscopic operation. The basic characteristics and pregnancy outcomes of individuals of the groups were compared, and propensity score matched (PSM) analysis was used to produce 37 matched pairs.Results: Before PSM, the UAE group had a thinner muscle layer, larger mass size, and higher serum human chorionic gonadotropin level than the non-UAE group. The pregnancy rate and live birth rate of the UAE group were 54.9% and 61.9%, respectively, which were lower than those of the non-UAE group (61.5% and 66.7%), but no statistical differences were observed. Post-PSM, no significant differences between basic characteristics of the groups were observed. The pregnancy rate of the UAE group was 51.4%, lower than that of the non-UAE group (73.0%). The live birth rate of the UAE group was 64.3%, also lower than that of the non-UAE group (72.7%); however, the difference was not statistically significant.Conclusion: Prophylactic UAE is a safe and effective adjuvant treatment for CSP, and has no significant effect on subsequent pregnancy and live birth rates.

Abstract PurposeThe suppression of luteinizing hormone (LH) in patients undergoing gonadotropin-releasing hormone agonist (GnRH-a) pituitary down-regulation may cause LH deficiency which may impact follicular development. However, little is known about effect of LH adding in patients with LH over-suppression. This study to investigate the effects of different gonadotropins on the cumulative live birth rate (CLBR) in the patients with LH over-suppression after GnRH-a pituitary down-regulation. MethodsThis retrospective study used propensity score-matching methodology to compare CLBR, as the primary endpoint, in the patients with LH over-suppression after different GnRH-a pituitary down-regulation regimens, including recombinant follicle stimulating hormone (rFSH) combined with recombinant LH (rLH), or using rFSH alone, or human menopausal gonadotropin (hMG) alone. The secondary endpoints included biochemical pregnancy rate, clinical pregnancy rate, and live birth rate in fresh embryo transfer cycles. ResultsA total of 88 patients were enrolled after matching: 22 patients in the rFSH+rLH group, 44 in the rFSH group, and 22 in the hMG group. The CLBR of the rFSH+rLH group was significantly higher than that of the rFSH and hMG groups (19/22, 86.4% vs. 25/44, 56.8%, P = 0.014; vs. 7/22, 31.8%, P < 0.001). Moreover, the rFSH group had a higher CLBR than the hMG group (P = 0.048). There were no significant differences in any of the secondary endpoints (all P > 0.05). ConclusionExogenous rLH supplementation achieved a higher CLBR than rFSH or hMG alone among patients with LH over-suppression; furthermore, rFSH alone was superior to hMG alone for CLBR.

This study compared the cumulative live birth rates following Intracytoplasmic sperm injection (ICSI) versus conventional in vitro fertilization (cIVF) in women aged 40 years or more and unexplained infertility. A cohort of 685 women undergoing either autologous conventional IVF or ICSI was retrospectively analyzed. The effects of conventional IVF or ICSI procedure on cumulative pregnancy and live birth rates were evaluated in univariate and in multivariable analysis. In order to reduce potential differences between women undergoing either IVF or ICSI and to obtain unbiased estimation of the treatment effect, propensity score was estimated. ICSI was performed in 307 couples (ICSI group), whereas cIVF was performed in 297 couples (cIVF group), resulting in 45 and 43 live deliveries, respectively. No differences were observed in morphological embryo quality, in the number of cleavage stage embryos, in the number of transferred embryos, and in the number of vitrified embryos. As for the clinical outcome, no differences were observed in pregnancy rate, cumulative pregnancy rate, live birth rate, cumulative live birth rate, and abortion rate. The present results suggest that ICSI is not associated with increased likelihood of a live birth for unexplained, non-male factor infertility, in women aged 40 years or more.

Abstract Background The ideal protocols of endometrial preparation for polycystic ovary syndrome (PCOS) patients are lacking and need further declaration. Our objective was to compare the clinical outcomes of frozen-thawed embryo transfer (FET) with and without pretreatment gonadotropin-releasing hormone agonist (GnRHa) in PCOS patients. Methods In this retrospective cohort study, we used propensity score matching (PSM) to compare the live birth rate between patients who underwent FET with hormone replacement treatment (HRT) and patients with GnRHa pretreatment (GnRHa + HRT). Patients using GnRHa + HRT (n = 514) were matched with 514 patients using HRT. Results The live birth rate was higher in the GnRHa + HRT group compared with the HRT group with no significant difference (60.12% vs 56.03%, p = 0.073). The clinical pregnancy rate (75.29% vs 70.62%), miscarriage rate (14.20% vs 13.81%) and ectopic pregnancy rate (0.39% vs 0.19%) were similar between the two groups. The preterm birth rate in GnRHa + HRT was higher than HRT (20.23% vs 13.04%). No difference was found in live birth between GnRHa +HRT and HRT before adjusting for covariates (crude OR 1.22, 95%CI, 0.99–1.51, p = 0.062) and after PSM (OR 1.47, 95%CI, 0.99–2.83, p = 0.068). In addition, there is a marginally difference after adjusting for covariates (aOR 1.56, 95%CI, 1.001–2.41, p = 0.048), this finding with p-value close to 0.05 represent insufficient empirical evidence. Similar results were obtained after propensity score matching in the entire cohort. Conclusions GnRHa pretreatment could not improve the live birth rate in women with PCOS.

Abstract Background Traditionally, final follicular maturation is triggered by a single bolus of human chorionic gonadotropin (hCG). This acts as a surrogate to the naturally occurring luteinizing hormone (LH) surge to induce luteinization of the granulosa cells, resumption of meiosis and final oocyte maturation. More recently, a bolus of gonadotropin-releasing hormone (GnRH) agonist in combination with hCG (dual trigger) has been suggested as an alternative regimen to achieve final follicular maturation. Methods This study was a systematic review and meta-analysis of randomized trials evaluating the effect of dual trigger versus hCG trigger for follicular maturation on pregnancy outcomes in women undergoing in vitro fertilization (IVF). The primary outcome was the live birth rate (LBR) per started cycle. Results A total of 1048 participants were included in the analysis, with 519 in the dual trigger group and 529 in the hCG trigger group. Dual trigger treatment was associated with a significantly higher LBR per started cycle compared with the hCG trigger treatment (risk ratio (RR) = 1.37 [1.07, 1.76], I2 = 0%, moderate evidence). There was a trend towards an increase in both ongoing pregnancy rate (RR = 1.34 [0.96, 1.89], I2 = 0%, low evidence) and implantation rate (RR = 1.31 [0.90, 1.91], I2 = 76%, low evidence) with dual trigger treatment compared with hCG trigger treatment. Dual trigger treatment was associated with a significant increase in clinical pregnancy rate (RR = 1.29 [1.10, 1.52], I2 = 13%, low evidence), number of oocytes collected (mean difference (MD) = 1.52 [0.59, 2.46), I2 = 53%, low evidence), number of mature oocytes collected (MD = 1.01 [0.43, 1.58], I2 = 18%, low evidence), number of fertilized oocytes (MD = 0.73 [0.16, 1.30], I2 = 7%, low evidence) and significantly more usable embryos (MD = 0.90 [0.42, 1.38], I2 = 0%, low evidence). Conclusion Dual trigger treatment with GnRH agonist and HCG is associated with an increased live birth rate compared with conventional hCG trigger. Trial registration CRD42020204452.

We examined whether treatment with minimum-dose stimulation (MS) protocol enhances clinical pregnancy rates compared to high-dose stimulation (HS) protocol. A retrospective cohort study was performed comparing IVF and pregnancy outcomes between MS and HS gonadotropin-antagonist protocol for patients with poor ovarian reserve (POR). Inclusion criteria included patients with an anti-Müllerian hormone (AMH) ≤8 pmol/L and/or antral follicle count (AFC) ≤5 on days 2-3 of the cycle. Patients from 2008 exclusively had a HS protocol treatment, while patients in 2010 had treatment with a MS protocol exclusively. The MS protocol involved letrozole at 2.5 mg over 5 days, starting from day 2, overlapping with gonadotropins, starting from the third day of letrozole at 150 units daily. GnRH antagonist was introduced once one or more follicles reached 14 mm or larger. The HS group received gonadotropins (≥300 IU/day) throughout their antagonist cycle. Clinical pregnancy rate was significantly higher in the MS protocol compared to the HS protocol (P=0.007). Furthermore, the live birth rate was significantly higher in the MS group compare to the HS group (P=0.034). In conclusion, the MS IVF protocol is less expensive (lower gonadotropin dosage) and resulted in a higher clinical pregnancy rate and live birth rate than a HS protocol for poor responders.

Background: Many guidelines have been issued regarding the number of embryos to be transferred after in vitro fertilization (IVF), but patients and clinicians may be reluctant to accept or offer a single embryo transfer due to the expected lower chance of pregnancy or live birth. This study was aimed to provide additional information on cycle outcome according to the number and quality of thawed transferred blastocysts. Methods:A retrospective cohort study was designed to collect the data of 505 patients who performed the first frozen blastocysts transfer at Tam Anh General Hospital from June 2018 to September 2019. One good-quality embryo was transferred for 121 patients (Group 1), two good for 214 patients (Group 2), one good and one poor for 112 patients (Group 3), one good and two poor for 25 patients (Group 4), and one or two poor for 33 patients (Group 5). Results:The pregnancy rate was 71.9%, 74.8%, 69.4%, 84.0%, and 39.4% in Group 1–5, respectively. The multiple pregnancy rate was 36.9%, 16.9%, and 32.0% in Groups 2–4, respectively, higher than Group 1 (4.9%). The live birth rate was 55.6%, 50.9%, and 60.0% in Group 2–4, respectively, but not significantly different from the Group 1 (47.9%). Conclusions:Transferring an additional good or poor embryo, along with a good embryo, does not increase the live birth rate while the incidence of multiple pregnancies rises significantly.

Abstract Background So far, only few literatures have studied the relationship between blastocyst transfer position and ART outcomes, and the conclusions are still controversial. Our study is to evaluate the effect of air bubble position on ART outcome and to find the optimal embryo transfer position in frozen-thawed blastocyst transfer. Methods This study included a retrospective cohort analysis of 399 frozen-thawed single blastocyst transfers ultrasound-guided performed between June 1, 2017 and November 30, 2020. All of the women scheduled for frozen-thawed single blastocyst transfers ultrasound-guided. The primary outcome is clinical pregnancy rate and the secondary outcome is live birth rate. Statistical analyses were conducted using One-way Anova, Kruscal Whallis H test, chi-square test and Smooth curve fitting. Results When BFD was less than 19 mm, there was no significant change in clinical pregnancy rate as BFD increased (OR = 0.95, 95% CI: 0.89 to 1.02, P = 0.1373); when BFD was more than 19 mm, the clinical pregnancy rate decreased by 16% for every 1 mm increase in BFD (OR = 0.84, 95% CI: 0.72 to 0.98, P = 0.0363). The effect of BFD on live birth rate were similar to that on clinical pregnancy rate, the inflection point was 19mm, when BFD was more than 19 mm, the live birth rate decreases by 58% for every 1 mm increase in BFD (OR = 0.42, 95% CI: 0.21 to 0.86, P = 0.0174) Conclusions The ideal pregnancy outcome can be achieved within 19mm from uterus fundus after single blastocyst transfer, The clinical pregnancy and live birth at a distance of more 19mm from the uterus fundus have a cliff-like downward trend.

Abstract Background: Along with progress in embryo cryopreservation, especially in vitrification has made freeze all strategy more acceptable. Some studies found comparable or higher live birth rate with frozen embryo transfer (FET) than with fresh embryo transfer（ET）in gonadotropin releasing hormone antagonist (GnRH-ant) protocol. But there were no reports about live birth rate differences between fresh ET and FET with gonadotropin releasing hormone agonist (GnRH-a) long protocol. The aim of this study is to analyze whether patients benefit from freeze all strategy in GnRH-a protocol from real-world data.Methods: This is a retrospective cohort study, in which women undergoing fresh ET or FET with GnRH-a long protocol at Chongqing Reproductive and Genetics Institute from January 2016 to December 2018 were evaluated. The primary outcome was live birth rate. The secondary outcomes were implantation rate, clinical pregnancy rate, pregnancy loss and ectopic pregnancy rate.Results: A total of 7,814 patients met inclusion criteria, implementing 5,216 fresh ET cycles and 2,598 FET cycles, respectively. The demographic characteristics of the patients were significantly different between two groups, except BMI. After controlling for a broad range of potential confounders (including age, infertility duration, BMI, AMH, no. of oocytes retrieved and no. of available embryos), multivariate logistic regression analysis demonstrated that there was no significant difference in terms of clinical pregnancy rate, ectopic pregnancy rate and pregnancy loss rate between two groups (all P>0.05). However, the implantation rate and live birth rate of fresh ET group were significantly higher than FET group (P<0.001 and P=0.012, respectively).Conclusion: Compared to FET, fresh ET following GnRH-a long protocol could lead to higher implantation rate and live birth rate in infertile patients underwent in vitro fertilization (IVF). The freeze all strategy should be individualized and made with caution especially with GnRH-a long protocol.

Abstract Study question What is the live birth rate after frozen embryo transfer (FET) of slow-growing embryos frozen on day 5 (D5) or on day 6 (D6)? Summary answer The live birth rate after single FET is significantly higher for slow-growing embryos frozen on D5 compared to those frozen on D6. What is known already Most data on the outcomes of blastocyst transfer stem from studies that evaluate fresh transfer from normal growing D5 blastocyst ET. However not all embryos will begin blastulation nor reach the fully expanded stage by D5; those are the slow-growing embryos. Studies that compare D5 to D6 embryos in FET cycles show contradictory results. Some have reported higher clinical pregnancy rates after D5 FET, while others have reported similar outcomes for D5 and D6 cryopreserved blastocyst transfers. There is a lack of evidence regarding the best approach for vitrifying embryos that exhibit a slow developmental kinetic. Study design, size, duration This retrospective cohort study included 821 single FET of slow-growing embryos frozen on D5 or D6, belonging to patients undergoing in vitro fertilization with donor oocytes between January 2011 and October 2019, in a single fertility center. The origin of blastocysts was either supernumerary embryos after fresh embryo transfer or blastocysts from freeze-all cycles. All embryos were transferred 2- 4h after thawing. Participants/materials, setting, methods We compared reproductive outcomes of slow-growing embryos frozen on D5 versus (n = 442) slow-growing embryos frozen on D6 (n = 379). D5 group consisted in embryos graded 0, 1, 2 of Gardner scale and frozen on D5. Similarly, D6 group consisted in embryos graded 3, 4, 5 of Gardner scale (blastocyst stage) and frozen on D6. Differences in pregnancy rates between study groups were compared using a Chi2 test. A p-value &lt;0.05 was considered statistically significant. Main results and the role of chance Baseline characteristics were comparable between study groups. Overall, mean age of the woman was 42.3±5.4 years old; donor sperm was used in 25% of cycles, and it was frozen in 73.2% of cycles. Pregnancy rates were significantly higher when transferring slow D5 embryos compared to D6 for all the pregnancy outcomes analyzed: biochemical pregnancy rate was 27.7% vs 20.2%, p &lt; 0.016; clinical pregnancy rate was 17.5% vs 10.2%, p &lt; 0.004); ongoing pregnancy rate was: 15.7% vs 7.8% (p &lt; 0.001); live birth rate was: 15.4% vs 7.5%, (p &lt; 0.001). These results suggest that when embryos exhibit a slow development behavior (not reaching full blastocysts at D5), waiting until D6 for blastulation and expansion does not improve clinical outcomes. Vitrification at D5 will should the preferred option in cases where the oocyte is assumed of high quality Limitations, reasons for caution The retrospective design of the study is its main limitation. Also, morphology as sole selection criterion for transfer. However, blastocyst morphology is a very good predictor of implantation and pregnancy, and a good indicator of the embryo’s chromosomal status (higher euploidy rate in higher morphological quality blastocysts). Wider implications of the findings: These results can help to the standardization of laboratory protocols. As the decision of vitrifying slow developing embryos on D5 or D6 is made by the laboratory team or by the gynaecologist in agreement with the patient, having an evidence based strategy simplifies patient counselling and decision making.
