RESUMEN
To investigate the effects of hepatitis B virus (HBV) infection on the outcomes of Chinese couples undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) and the clinical data of their neonates. A total of 21,999 first embryo transfer cycles were included. They were categorized into four groups based on the couple's hepatitis B surface antigen (HBsAg) result (Group A = female HBsAg- and male HBsAg- ; Group B = female HBsAg+ and male HBsAg- ; Group C = female HBsAg- and male HBsAg+ ; Group D = female HBsAg+ and male HBsAg+ ). The fertilization rate (FR), cleavage rate (CR), implantation rate (IPR), clinical pregnancy rate (CPR), live birth rate (LBR) and miscarriage rate (MCR) were analysed. Multilevel logistic regression was applied to evaluate the association. The total prevalence of HBV infection was 5.74% (2526/43998). There were no statistically significant differences in CRs (98.69%, 98.76%, 98.66%, 98.72%, p > .05), IPRs (45.86%, 47.33%, 45.19%, 39.61%, p > .05), CPRs (62.84%, 65.05%, 61.80%, 56.81%, p > .05), MCRs (12.70%, 11.99%, 12.58%, 4%, p > .05) and LBRs (53.43%, 55.38%, 52.70%, 54.54%, p > .05) among the four groups. However, there were significant differences in FRs (66.25%, 66.55%, 66.32%, 61.92%, p < .05). Group D had the lowest FR. After adjusting for confounders, the multilevel logistic regression showed that HBsAg+ had no impact on the LBR, CPR or MCR. We also analysed the data of 14,465 newborns, including 8593 singletons and 2936 twins. Among the four groups, no variables reached statistical significance, including neonatal birth weight (NBW), twin ratio, gestational age, premature birth, delivery type, fetal macrosomia or low birth weight (p > .05). Our study demonstrates that, although biparental HBV infection may affect the FR, neither single-parent infection nor biparental HBV infection affects IVF/ICSI outcomes or neonatal outcomes.

RESUMEN
Objective: To determine the effect of gender of reciprocal chromosomal translocation on blastocyst formation and pregnancy outcome in preimplantation genetic testing, including different parental ages. Methods: This was a retrospective cohort study that enrolled 1034 couples undergoing preimplantation genetic testing-structural rearrangement on account of a carrier of reciprocal chromosomal translocation from the Reproductive Medicine Center of the First Affiliated Hospital of Zhengzhou University from January 2015 to December 2019. Group A represented 528 couples in which the man was the carrier of reciprocal translocation and group B represented 506 couples in which the woman was the carrier of reciprocal translocation. All patients were divided into two groups according to their age: female age<35 and female age≥35. Furthermore, the differences in blastocyst condition and pregnancy outcome between male and female carriers in each group were further explored according to their father's age. Results: The blastocyst formation rate of group A (55.3%) is higher than that of group B (50%) and the results were statistically significant (P<0.05). The blastocyst formation rate of group A is higher than that of group B, no matter in young maternal age or in advanced maternal age (P<0.05). The blastocyst formation rate in maternal age<35y and paternal age<30y in group A(57.1%) is higher than that of Group B(50%); Similarly, the blastocyst formation rate in maternal age≥35 and paternal age≥38y(66.7%) is higher than that of Group B(33.3%)(all P<0.05). There was no difference in fertilization rate, aeuploidy rate, clinical pregnancy rate, miscarriage rate and live birth rate between Group A and Group B. Conclusion: When the carrier of reciprocal translocation is male, the blastocyst formation rate is higher than that of female carrier. While there is no significant difference between the two in terms of fertilization rate, aeuploidy rate, clinical pregnancy rate, miscarriage rate and live birth rate.

The aim of this study is to evaluate the reproductive outcomes of patients with previous cesarean section (CS) undergoing single-embryo transfer (SET). A total of 5479 patients previously underwent CS or vaginal delivery (VD) were included. The patients with previous CS included single/double cleavage (SCT/DCT), single/double blastocyst stage embryo transfer (SBT/DBT). The comparison of reproductive outcomes between CS and VD, SET, and double-embryo transfer of CS was conducted. The main outcome measures included clinical pregnancy rate (CPR), multiple pregnancy rate (MPR), live birth rate (LBR), and cumulative live birth rate (CLBR). There were no differences in CPR and LBR between patients previously underwent CS and VD, and the preterm birth rate of multiple births in patients underwent CS were significantly higher than underwent VD. As for patients underwent CS, the CPR, MPR, and LBR were lower in patients treated with SCT than DCT in IVF/ICSI cycles. The CPR and LBR of patients treated with SCT were not statistically different compared with DCT and SBT when patients' age were younger than 35 years in FET cycles, and the MPR of patients treated with SCT was lower. The CPR and LBR of patients treated with SCT were lower than DCT/SBT when patients' age were 35 years or older in FET cycles. The CPR, LBR, and CLBR of patients treated with SBT were not lower than DCT in IVF/ICSI-ET, FET, and complete cycles, but the MPR was lower. Reducing the number of embryos transferred should be considered seriously for CS. SCT under the 35 years of FET cycles is feasible. SBT is an effective strategy to reduce MPR of IVF/ICSI, FET, and complete cycles regardless of overall or age stratification.

Objective: To study the risk factors for recurrent ectopic pregnancy (REP) in patients undergoing in vitro fertilization (IVF). Methods: This was a 1:4 matched case-control study that enrolled 227 REP patients and 908 matched intrauterine pregnancy (IUP) patients from the assisted reproductive technology (ART) center of the First Affiliated Hospital of Zhengzhou University from January 2012 to November 2019. Univariate analysis was carried out between the two groups for the occurrence of REP. Multivariate logistic regression analysis was used to explore the risk factors of REP after IVF. Results: The results of univariate analysis showed that there were significant differences in previous treatment of EP, stage of embryo and the number of embryos transferred between the two groups (all P < 0.05). The other factors did not have a significant effect on the probability of developing REP. Multivariate logistic regression analysis showed that after adjusting for confounders, previous treatment of EP, type of embryos transferred and stage of embryo were related to the occurrence of REP (all P < 0.05). Conclusion: Conservative treatment, frozen-thawed embryo transfer and cleavage embryo transfer were independent risk factors for REP after ART treatment.

The aim of this study was to investigate the factors predicting clinical pregnancy rate of in vitro fertilization-embryo transfer (IVF-ET).The data of 9960 patients receiving IVF-ET fresh cycle at our Reproductive Center from January 2009 to December 2017 were first divided into pregnant group and non-pregnant group to find the clinical pregnancy rate-related factors. According to the serum HCG levels at 36âhours and 12âhours after HCG trigger, all patients were divided into 4 groups including <50âmIU/ml, ≥50 and <100âmIU/ml, ≥100 and <200âmIU/ml, and ≥200âmIU/ml groups to know whether the HCG levels at 36âhours and 12âhours affect the pregnancy rate. According to the serum HCG ratio at 36âhours to 12âhours (36âh/12âh) after HCG trigger, all patients were divided into three groups including <0.88, 0.88-1.06 and >1.06 groups to observe whether the serum HCG ratio (36âh/12âh) affects the clinical pregnancy rate. According to different assisted pregnancy modes, all patients were divided into 3 groups including IVF, ICSI, and IVF/ICSI groups to observe whether the assisted pregnancy mode affects the clinical pregnancy rate. The correlation of the clinical pregnancy rate with pregnancy rate-related factors obtained above was analyzed using logistic regression analysis model.The clinical pregnancy rate significantly increased (Pâ<â.01) in the HCG ratio (36âh/12âh) >1.06 group as compared with the HCG ratio (36âh/12âh)â<â0.88 and 0.88-1.06 groups. The serum estrogen (E2) level at 36âhours was significantly lower and the number of retrieved oocytes was significantly higher in the HCG ratio (36âh/12âh) >1.06 group than in the HCG ratio (36âh/12âh) <0.88 and 0.88-1.06 groups (Pâ=â.000).The serum HCG ratio (36âh/12âh) may be used as a predictor of IVF-ET clinical pregnancy rate. High clinical pregnancy rate is probably associated with E2 down-regulation in the HCG ratio (36âh/12âh) >1.06 group.

BACKGROUND: The study was designed to investigate the roles of endometrial thickness (EMT) at the day of human chorionic gonadotropin (hCG) administration on pregnancy outcomes in a large patient population. METHODS: This retrospective cohort study included 9,952 patients undergoing their first IVF/ICSI with autologous oocytes from January 2011 to January 2015. Patients were divided into three groups based on the EMT (group A:≤8 mm; group B: 9-14 mm and group C:≥15 mm). Live birth rate (LBR), clinical pregnancy rate (CPR), early miscarriage rate (EMR), and ectopic pregnancy rate (EPR) were analyzed. Additionally, the live birth rate was analyzed for patients with single or double gestational sacs. RESULTS: Significant differences (p < 0.05) were detected in the LBRs (30.38%, 45.73% and 54.55% for groups A, B, and C, respectively), CPRs (38.57%, 55.04% and 64.32%, respectively), and EPRs (5.58%, 3.48% and 2.19%, respectively), with thicker endometrial thickness favoring all three parameters. However, no differences were found in the EMRs among the three groups (15.64%, 13.44% and 13.05%, respectively, p > 0.05). After adjusting for female age, body mass index (BMI) and endometrial pattern, the multivariate logistic regression analysis demonstrated that the associations between EMT and LBR (adjusted OR: 2.645; 95% CI 2.020-3.464; p < 0.01), CPR (adjusted OR 2.693 95% CI 2.012-3.605 p < 0.01), and EPR (adjusted OR: 0.298 95% CI 0.101-0.713; p < 0.05) were significant. Additionally, live birth rates in the double gestational sac group were different (p < 0.05) among patients with different EMT (72.73%, 87.28%, and 87.36%, respectively), whereas no difference was found in the single gestational sac group. In the double gestational sac group, LBR was positively correlated with increasing endometrial thickness only in patients with twin pregnancies but not in patients with singletons. CONCLUSIONS: Our study shows that endometrial thickness at the day of hCG administration has an effect on LBR, CPR and EPR, with all three parameters increasing with the EMT. Furthermore, successful twin pregnancies are associated with a thicker endometrium.

We observed the effects of changes in progesterone (P) during late follicular phases on the treatment outcome of in vitro fertilization-embryo transfer (IVF-ET) and intracytoplasmic sperm injection (ICSI) in patients with different ovarian responses. The data of 8,575 cycles of patients receiving gonadotropin-releasing hormone (GnRH) agonist using the long protocol were retrospectively analyzed. According to the number of oocytes retrieved, the cycles were divided into poor ovarian response group (oocyte retrieval <5), intermediate ovarian response group (5≤ oocyte retrieval ≤15), and high ovarian response group (oocyte retrieval ≥16). We found that in the poor ovarian response group, the clinical pregnancy rate was not significantly associated with both the level of P or the day of human chorionic gonadotrophin (hCG) and the duration of pre-hCG P elevation (p = 0.66 and p = 0.1874). In intermediate and high ovarian response groups, the clinical pregnancy rate was inversely related to both the level of P on the day of hCG administration and the duration of pre-hCG P elevation (all p < 0.0001). The cut-off values of serum P level on the day of hCG administration were 1 ng/ml and 1.75 ng/ml in intermediate and high ovarian response groups, respectively. The cut-off values of pre-hCG P elevation duration were obtained on day 1 in the intermediate ovarian response group, and days 1 or 3 in the high ovarian response group. After correcting for other confounding factors, multivariate logistic regression analysis indicated that P level on the day of hCG administration was not associated with clinical pregnancy rates, but pre-hCG P elevation duration was negatively associated with clinical pregnancy rate in the intermediate and high ovarian response groups. P level is associated with clinical pregnancy rate only in the patients with intermediate or high ovarian response. The longer the duration of pre-hCG P 1 ng/ml, the lower the clinical pregnancy rate.
