Immune Factors

Recurrent reproductive failure (RRF), such as recurrent pregnancy loss and repeated implantation failure, is characterized by complex etiologies and particularly associated with diverse maternal factors. It is currently believed that RRF is closely associated with the maternal environment, which is, in turn, affected by complex immune factors. Without the use of automated tools, it is often difficult to assess the interaction and synergistic effects of the various immune factors on the pregnancy outcome. As a result, the application of Artificial Intelligence (A.I.) has been explored in the field of assisted reproductive technology (ART). In this study, we reviewed studies on the use of A.I. to develop prediction models for pregnancy outcomes of patients who underwent ART treatment. A limited amount of models based on genetic markers or common indices have been established for prediction of pregnancy outcome of patients with RRF. In this study, we applied A.I. to analyze the medical information of patients with RRF, including immune indicators. The entire clinical samples set (561 samples) was divided into two sets: 90% of the set was used for training and 10% for testing. Different data panels were established to predict pregnancy outcomes at four different gestational nodes, including biochemical pregnancy, clinical pregnancy, ongoing pregnancy, and live birth, respectively. The prediction models of pregnancy outcomes were established using sparse coding, based on six data panels: basic patient characteristics, hormone levels, autoantibodies, peripheral immunology, endometrial immunology, and embryo parameters. The six data panels covered 64 variables. In terms of biochemical pregnancy prediction, the area under curve (AUC) using the endometrial immunology panel was the largest (AUC = 0.766, accuracy: 73.0%). The AUC using the autoantibodies panel was the largest in predicting clinical pregnancy (AUC = 0.688, accuracy: 78.4%), ongoing pregnancy (AUC = 0.802, accuracy: 75.0%), and live birth (AUC = 0.909, accuracy: 89.7%). Combining the data panels did not significantly enhance the effect on prediction of all the four pregnancy outcomes. These results give us a new insight on reproductive immunology and establish the basis for assisting clinicians to plan more precise and personalized diagnosis and treatment for patients with RRF.

Abstract Objective: This retrospective study aimed to explore the optimal endometrial preparation method in women with intrauterine adhesions (IUAs).Method: A total of 882 frozen-thawed embryo transfer (FET) cycles were categorized into three groups based on endometrial preparation methods: hormone replacing therapy cycle (HRT, n=636), natural cycle (NC n=174), and HRT with GnRH-a pretreatment (HRT+GnRH-a, n=72. Logistic regression was performed to investigate the association between cycle regimens and pregnancy outcomes. Subgroup analysis of IUAs combined with thin endometrium (≤7mm) was also performed.Results: HRT with GnRH-a pretreatment was associated with higher incidences of clinical pregnancy, ongoing pregnancy, and live birth, but lower early miscarriage compared with either HRT or NC. Logistic regression indicated that after controlling for potential confounders, the incidences of live birth (HRT+GnRH-a as reference; NC: aOR=0.577, 95%CI 0.304-1.093; HRT: aOR=0.434, 95%CI 0.247-0.765) and ongoing pregnancy (NC: aOR=0.614, 95%CI 0.324-1.165; HRT: aOR=0.470, 95%CI 0.267-0.829) remained significantly higher in HRT+GnRH-a compared to those in HRT, but comparable to those in NC. While there was no significant difference with respect to the clinical pregnancy rate (NC: aOR=0.695, 95%CI 0.374-1.291; HRT: aOR=0.650, 95%CI 0.374-1.127) and early miscarriage rate (NC: aOR=1.734, 95%CI 0.417-7.175; HRT: aOR=2.594, 95%CI 0.718-9.378) between groups. Subgroup analysis suggested there was no priority of endometrial preparation method in IUAs combined with thin endometrium.Conclusion: HRT with GnRH-a pretreatment improves pregnancy outcomes in women with history of IUAs. GnRH-a may restore the endometrial receptivity in the FET cycles in IUAs.

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 Background: Although previous studies had successfully illustrated different pregnancy outcomes by different serum β-hCG levels after embryo transfer, prognosis of pregnancy outcomes remains elusive when the serum β-hCG level is extremely low (e.g., < 100 mIU/ml 14 days after embryo transfer). Therefore, the purpose of our study is to investigate the pregnancy outcomes of patients with low serum β-hCG level 14 days after day 3 embryo transfer. Methods: A retrospective study was performed with 723 patients with a serum β-hCG level between 5 and 100 mIU/ml 14 days after day 3 fresh embryo transfer. Pregnancy outcomes (ongoing pregnancy, early miscarriage, biochemical pregnancy loss, and ectopic pregnancy) were analyzed according to the female patients’ age. Receiver operating characteristic (ROC) curves were plotted to indicate the threshold for prediction of clinical pregnancy and ongoing pregnancy. Sensitivity and specificity were calculated according the ROC curves as well. Results: Of the 723 patients with serum β-hCG level <100 mIU/mL 14 days after day 3 embryo transfer, 85.6% (619) had biochemical pregnancy, and only 14.4% (104) had clinical pregnancy (including 4.7% with ongoing pregnancy, 3.7% with ectopic pregnancy, and 5.9% with early miscarriage). The rate of ongoing pregnancy was significantly lower in ≥ 38-year group compared with < 38-year group (1.3% vs. 5.6%, P =0.029). The serum β-hCG level to predict clinical pregnancy was 44.7 mIU/ml (sensitivity, 91.3%; specificity, 82.1%; area under the ROC curve (AUROC), 0.908). For ongoing pregnancy, the serum β-hCG level was 53.7 mIU/ml (sensitivity, 94.1%; specificity, 81.4%; AUROC, 0.902). Conclusions: Initially low serum β-hCG level 14 days after day 3 embryo transfer indicated poor prognosis with minimal likelihood of ongoing pregnancy.

Abstract Background: Although many previous study investigated the prediction of pregnancy outcomes by serumβ-hCG levels after blastocyst transfer, no study focused on the pregnancy outcomes of patients with initially low serum β-hCG levels. The purpose of the study was to investigate the pregnancy outcomes of patients with low serum β- level 14 days after blastocyst transfer. Methods: A retrospective study was performed in the Third Affiliated Hospital of Guangzhou Medical University. The purpose was to investigate the patients whose serum β-hCG levels were between 5-299 mIU/ml 14 days after frozen blastocyst transfer. Rates of live birth, early miscarriage, biochemical pregnancy loss and ectopic pregnancy were analyzed according to the female patients’ age by chi-squared test. Receiver operating characteristic (ROC) curves were plotted to explore the threshold for prediction of clinical pregnancy and live birth. Results: A total of 312 patients had serum β-hCG levels <300 mIU/ml 14 days after frozen blastocyst transfer, among which 18.6% were live birth, 47.4% were early miscarriage, 22.8% were biochemical pregnancy and 9.6% were ectopic pregnancy. Pregnancy outcomes were comparable between the patients aged <38 years and ≥38 years. ROC curve analysis showed that the predicted value ofβ-hCG for clinical pregnancy was 58.8 mIU/ml with the AUC of 0.752(95%CI :0.680-0.823), sensitivity of 95.0% and specificity of 53.5%.The threshold for live birth was 108.6mIU/ml with the area under the ROC curve (AUC) of 0.649(95%CI:0.0.583-0.715), sensitivity of 93.1% and specificity of 37.0%.For the β-hCG fold increase over 48 hours, the cut-off for clinical pregnancy was 1.4 with the AUC of 0.899(95%CI :0.801-0.996), sensitivity of 90.3% and specificity of 77.8%; the threshold for live birth was 1.9 with the AUC of 0.808(95%CI :0.724-0.891), sensitivity of 88.5% and specificity of 64.5%. Conclusions: Initially low serum β-hCG level 14 days after frozen blastocyst transfer indicated minimal likelihood of live birth. For patients having initial β-hCG >58.8 mIU/ml, luteal phase support is suggested to continue. Another serum β-hCG test and ultrasound should be performed one week later. If the initial serum β-hCG is < 58.8 mIU/ml, luteal phase support is suggested to discontinue and measurement of serum β-hCG and ultrasound can be arranged one week later.

Abstract Background This study compared the effectiveness of recombinant human follicle-stimulating hormone alfa (r-hFSH-alfa; GONAL-f®) with urinary highly purified human menopausal gonadotropin (hMG HP; Menogon HP®), during assisted reproductive technology (ART) treatments in Germany. Methods Data were collected from 71 German fertility centres between 01 January 2007 and 31 December 2012, for women undergoing a first stimulation cycle of ART treatment with r-hFSH-alfa or hMG HP. Primary outcomes were live birth, ongoing pregnancy and clinical pregnancy, based on cumulative data (fresh and frozen-thawed embryo transfers), analysed per patient (pP), per complete cycle (pCC) and per first complete cycle (pFC). Secondary outcomes were pregnancy loss (analysed per clinical pregnancy), cancelled cycles (analysed pCC), total drug usage per oocyte retrieved and time-to-live birth (TTLB; per calendar week and per cycle). Results Twenty-eight thousand six hundred forty-one women initiated a first treatment cycle (r-hFSH-alfa: 17,725 [61.9%]; hMG HP: 10,916 [38.1%]). After adjustment for confounding variables, treatment with r-hFSH-alfa versus hMG HP was associated with a significantly higher probability of live birth (hazard ratio [HR]-pP [95% confidence interval (CI)]: 1.10 [1.04, 1.16]; HR-pCC [95% CI]: 1.13 [1.08, 1.19]; relative risk [RR]-pFC [95% CI]: 1.09 [1.05, 1.15], ongoing pregnancy (HR-pP [95% CI]: 1.10 [1.04, 1.16]; HR-pCC [95% CI]: 1.13 [1.08, 1.19]; RR-pFC [95% CI]: 1.10 [1.05, 1.15]) and clinical pregnancy (HR-pP [95% CI]: 1.10 [1.05, 1.14]; HR-pCC [95% CI]: 1.14 [1.10, 1.19]; RR-pFC [95% CI]: 1.10 [1.06, 1.14]). Women treated with r-hFSH-alfa versus hMG HP had no statistically significant difference in pregnancy loss (HR [95% CI]: 1.07 [0.98, 1.17], were less likely to have a cycle cancellation (HR [95% CI]: 0.91 [0.84, 0.99]) and had no statistically significant difference in TTLB when measured in weeks (HR [95% CI]: 1.02 [0.97, 1.07]; p = 0.548); however, r-hFSH-alfa was associated with a significantly shorter TTLB when measured in cycles versus hMG HP (HR [95% CI]: 1.07 [1.02, 1.13]; p = 0.003). There was an average of 47% less drug used per oocyte retrieved with r-hFSH-alfa versus hMG HP. Conclusions This large (> 28,000 women), real-world study demonstrated significantly higher rates of cumulative live birth, cumulative ongoing pregnancy and cumulative clinical pregnancy with r-hFSH-alfa versus hMG HP.

Abstract Background Various luteal phase supports (LPSs) have been proven to increase the pregnancy rate in fresh cycles of in vitro fertilization or intracytoplasmic sperm injection; however, there is still significant debate regarding the optimal use of LPS. Methods A systematic review with the use of a network meta-analysis was performed via electronic searching of Ovid MEDLINE, the Cochrane Library, Embase, Web of Science, ClinicalTrials.gov and Google Scholar (up to January 2021) to compare the effectiveness and safety of various LPSs, as well as to evaluate the effects of different initiations of LPSs on pregnancy outcomes. The primary outcomes included live birth and ongoing pregnancy, with the results presented as odds ratios (ORs) with 95% confidence intervals (CIs). Results Eighty-nine randomized controlled trials with 29,625 women comparing 14 interventions or placebo/no LPS treatments were included in the meta-analyses. No significant differences were found in terms of the pregnancy outcomes when LPS was started within 48 h after oocyte retrieval versus a delayed initiation between 48 h and 96 h after oocyte retrieval. The addition of gonadotropin-releasing hormone (GnRH) agonists to progesterone vaginal pessaries showed a significant benefit in terms of live birth (OR 1.39, 95% CI 1.08 to 1.78). Only human chorionic gonadotropin (HCG) was found to be more efficacious than the placebo/no LPS treatment in terms of live birth (OR 15.43, 95% CI 2.03 to 117.12, low evidence). Any active LPSs (except for rectal or subcutaneous progesterone) was significantly more efficacious than the placebo/no LPS treatment in terms of ongoing pregnancy, with ORs ranging between 1.77 (95% CI 1.08 to 2.90) for the vaginal progesterone pessary and 2.14 (1.23 to 3.70) for the intramuscular progesterone treatment. Among the comparisons of efficacy and tolerability between the active treatments, the differences were small and very uncertain. Conclusion Delays in progesterone supplementation until 96 h after oocyte retrieval does not affect pregnancy outcomes. The safety of GnRH agonists during the luteal phase needs to be evaluated in future studies before the applications of these agonists in clinical practice. With comparable efficacy and acceptability, there may be several viable clinical options for LPS.

Abstract Background High-quality single blastocyst transfer (SBT) is increasingly recommended to patients because of its acceptable pregnancy outcomes and significantly reduced multiple pregnancy rate compared to double blastocyst transfer (DBT). However, there is no consensus on whether this transfer strategy is also suitable for poor-quality blastocysts. Moreover, the effect of the development speed of poor-quality blastocysts on pregnancy outcomes has been controversial. Therefore, this study aimed to explore the effects of blastocyst development speed and morphology on pregnancy and neonatal outcomes during the frozen embryo transfer (FET) cycle of poor-quality blastocysts and to ultimately provide references for clinical transfer strategies. Methods A total of 2,038 FET cycles of poor-quality blastocysts from patients 40 years old or less were included from January 2014 to December 2019 and divided based on the blastocyst development speed and number of embryos transferred: the D5-SBT (n = 476), D5-DBT (n = 365), D6-SBT (n = 730), and D6-DBT (n = 467) groups. The SBT group was further divided based on embryo morphology: D5-AC/BC (n = 407), D5-CA/CB (n = 69), D6-AC/BC (n = 580), and D6-CA /CB (n = 150). Results When blastocysts reach the same development speed, the live birth and multiple pregnancy rates of DBT were significantly higher than those of SBT. Moreover, there was no statistical difference in the rates of early miscarriage and live birth between the AC/BC and CA/CB groups. When patients in the SBT group were stratified by blastocyst development speed, the rates of clinical pregnancy (42.44 % vs. 20.82 %) and live birth (32.35 % vs. 14.25 %) of D5-SBT group were significantly higher than those of D6-SBT group. Furthermore, for blastocysts in the same morphology group (AC/BC or CA/CA group), the rates of clinical pregnancy and live birth in the D5 group were also significantly higher than those of D6 group. Conclusions For poor-quality D5 blastocysts, SBT can be recommended to patients because of acceptable pregnancy outcomes and significantly reduced multiple pregnancy rate compared with DBT. For poor-quality D6, the DBT strategy is recommended to patients to improve pregnancy outcomes. When blastocysts reach the same development speed, the transfer strategy of selecting blastocyst with inner cell mass “C” or blastocyst with trophectoderm “C” does not affect the pregnancy and neonatal outcomes.

Abstract Objective: This retrospective study aimed to explore the optimal endometrial preparation method in women with intrauterine adhesions (IUAs).Method: A total of 882 frozen-thawed embryo transfer (FET) cycles from patients with history of IUAs were categorized into three groups based on endometrial preparation methods: hormone replacing therapy cycle (HRT, n=636), natural cycle (NC n=174), and HRT with GnRH-a pretreatment (HRT+GnRH-a, n=72. Logistic regression was performed to investigate the association between cycle regimens and pregnancy outcomes. Subgroup analysis of IUAs combined with thin endometrium (≤7mm) was also performed.Results: HRT with GnRH-a pretreatment was associated with higher incidences of clinical pregnancy, ongoing pregnancy, and live birth, but lower early miscarriage compared with either HRT or NC. Logistic regression indicated that after controlling for potential confounders, the incidences of live birth (HRT+GnRH-a as reference; NC: aOR=0.577, 95%CI 0.304-1.093; HRT: aOR=0.434, 95%CI 0.247-0.765) and ongoing pregnancy (NC: aOR=0.614, 95%CI 0.324-1.165; HRT: aOR=0.470, 95%CI 0.267-0.829) remained significantly higher in HRT+GnRH-a compared to those in HRT, but comparable to those in NC. While there was no significant difference with respect to the clinical pregnancy rate (NC: aOR=0.695, 95%CI 0.374-1.291; HRT: aOR=0.650, 95%CI 0.374-1.127) and early miscarriage rate (NC: aOR=1.734, 95%CI 0.417-7.175; HRT: aOR=2.594, 95%CI 0.718-9.378) between groups. Subgroup analysis suggested there was no superiority of endometrial preparation method in IUAs combined with thin endometrium.Conclusion: HRT with GnRH-a pretreatment improves pregnancy outcomes in women with history of IUAs. GnRH-a may restore the endometrial receptivity in the FET cycles in IUAs.

Abstract Study question Is dydrogesterone (DYG) equivalent compared to cetrorelix with respect to clinical pregnancy rate, ongoing pregnancy rate and live birth rate in oocyte donation (OD) cycles? Summary answer DYG is comparable to cetrorelix in terms of clinical pregnancy, but higher rates of ongoing pregnancy and live birth were observed in the DYG group What is known already Progestin-primed ovarian stimulation (PPOS) is an ovarian stimulation regimen based on a freeze-all strategy using progestin as an alternative to GnRH analog for suppressing a premature LH surge. DYG is an oral progestin that has been studied in PPOS protocols. Published reports indicate that length of ovarian stimulation, dose of gonadotrophin needed and number of MII retrieved from PPOS cycles are comparable to short protocol of GnRH agonists during OD cycles. However, while some studies noted no differences in terms of live births, worse pregnancy rates have been reported in recipients of oocytes from PPOS cycles compared to GnRH antagonists. Study design, size, duration Prospective controlled study to assess the reproductive outcomes of OD recipients in which the donors were subjected to the DYG protocol (20mg/day) compared with those subjected to the short protocol with cetrorelix (0.25 mg/day) from Day 7 or since a leading follicle reached 14 mm. The OD cycles were triggered with triptoreline acetate and the trigger criterion was ≥3 follicles of diameter &gt;18mm. Participants/materials, setting, methods 202 oocyte donors were included, 92 under DYG and 110 under cetrorelix. The study was performed in a private infertility center between January 2017 and December 2020. The main outcome included the rates of clinical pregnancy, ongoing pregnancy and live births. Secondary outcomes included the number of oocytes retrieved, number of MII, fertilization rate, length of stimulation and total gonadotropin dose. Differences were tested using a Student’s t-test or a Chi2 test, as appropriate. Main results and the role of chance Compared to antagonist cycles, cycles under DYG had fewer days of stimulation (9.9 ± 0.9 vs. 10.8 ± 1.1, p&lt;.001) and a lower total gonadotropin dose (1654 ± 402.4 IU vs. 1844 ± 422 IU, p&lt;.001). The number of MII retrieved was no different: 16.9 (SD 6.2) with DYG and 15.4 (SD 5.8) with cetrorelix (p = 0.072). Recipients and embryo transfer (ET) characteristics were also similar between groups. The mean number of MII assigned to each recipients was 6.7 (SD 1.8) in DYG and 6.6 (SD 1.7) in cetrorelix (P = 0.446). The fertilization rate was 66.2% in DYG versus 67.6% in cetrorelix (P = 0.68). Regarding the reproductive outcomes, the overall clinical pregnancy rate in DYG group (65/87: 74.7%) and cetrorelix group (66/104: 63.4%) (p = 0.118) was similar. Meanwhile, the DYG group compared to cetrorelix group had higher rates of ongoing pregnancy (63.2% vs 45.1%; p = 0.014) and live births (54,9% vs 37.8%; p = 0.040). Limitations, reasons for caution These results should be evaluated with caution. The limitations of this study include the limited number of participants enrolled and the limited data on pregnancy outcomes. A randomized controlled trial is necessary to provide more evidence on the efficacy of the DYG protocol. Wider implications of the findings: The efficacy of PPOS protocol compared to GnRH-antagonist protocol in terms of reproductive outcomes has been little studied. PPOS using DYG yields comparable clinical pregnancy rates compared to cetrorelix in OD cycles. The differences found regarding the rates of ongoing pregnancy and live births should be further investigated. Trial registration number Not applicable

Objective This retrospective study was conducted to explore causes of unsynchronized follicular maturation (UFM) and analyze the effects of large follicle puncture on embryo quality and pregnancy outcome. Methods Clinical features and controlled ovulation hyperstimulation (COH) were compared between the puncture group (n = 48) and the control group (n = 2545). We analyzed the COH process with in vitro fertilization during fresh cycle embryo transfer with different clinical pregnancy outcomes. We compared clinical characteristics and COH process of patients in the clinical pregnancy (n = 774) and non-clinical pregnancy (n = 527) groups. Finally, factors related to pregnancy outcomes were analyzed using multivariate logistic regression analysis. Results Age, level of estradiol on down-regulation day, and initial gonadotropin dose were significantly higher in the puncture group than in the control group. We detected significant differences in age, infertility, and body mass index (BMI) between the clinical and non-clinical pregnancy groups. Age, BMI, and endometrial thickness on the day of human chorionic gonadotropin administration were the independent factors influencing pregnancy outcome. Conclusions Patient’s age and level of anti-Müllerian hormone were the main factors causing UFM in patients undergoing COH. Large follicle puncture had no significant effect on pregnancy outcome.
