AbstractThis study monitors the effect of male smoking and age of the woman on the success of the intracytoplasmic sperm injection (ICSI) fertilization process as part of the assisted reproduction technique (ART). A total of 703 couples in the in vitro fertilization (IVF) program were included. Binary logistic regression analysis was used to study the effect of male smoking on clinical pregnancy rate and live birth rate. The results from the study showed that interaction of male smoking and women’s age (>35 years) have significant negative impact on ongoing pregnancy rate and live birth rate.

Objective: To evaluate the efficacy of acupuncture compared to placebo acupuncture for women undergoing in vitro fertilisation (IVF) in a systematic review and meta-analysis. Methods: A search was conducted in seven English-language biomedical databases from their inception to 3 April 2019 to identify studies evaluating acupuncture as an adjunct to IVF treatment. Randomised controlled trials (RCTs) that compared acupuncture with placebo acupuncture using a non-invasive placebo acupuncture device in women undergoing a fresh or frozen IVF cycle were eligible, as were studies that tested placebo acupuncture as the intervention. Outcomes were clinical pregnancy rate, ongoing pregnancy rate, miscarriage rate, live birth rate and adverse events. Results: Eight RCTs involving 3607 women were included. Studies were judged to be low risk for most of the risk of bias domains. Acupuncture around the time of embryo transfer was not significantly different to placebo acupuncture in terms of the clinical pregnancy rate (6 RCTs, 2473 women, risk ratio (RR) = 0.99 (95% confidence interval (CI) = 0.88, 1.11), I2 = 51%, moderate certainty evidence), ongoing pregnancy rate (4 RCTs, 1459 women, RR = 0.88 (95% CI = 0.75, 1.02), I2 = 50%, moderate certainty evidence), miscarriage rate (4 RCTs, 502 women, RR = 1.23 (95% CI = 0.89, 1.71), I2 = 30%, high certainty evidence) or live birth rate (4 RCTs, 1835 women, RR = 0.87 (95% CI = 0.75, 1.01), I2 = 0%, high certainty evidence). Outcomes with placebo acupuncture were not significantly different to usual care. Adverse events relating to acupuncture, such as discomfort and bruising, were mild to moderate. Conclusion: Acupuncture administered around the time of embryo transfer did not have a statistically significant effect on IVF outcomes compared with placebo acupuncture.

BackgroundThe definition of recurrent implantation failure (RIF) differs clinically, one of the most controversial diagnostic criteria is the number of failed treatment cycles. We tried to investigate whether the two implantation failure could be included in the diagnostic criteria of RIF.MethodsA retrospective analysis of the clinical data of patients (N=1518) aged under 40 years with two or more implantation failure, recruited from the Center for Reproductive Medicine of the First Affiliated Hospital of Zhengzhou University from January 2016 to June 2019.ResultsAfter adjusting for confounding factors by using binary logistic regression, the results showed that partial general information and: distribution of associated factors were significant differences such as maternal age (aOR=1.054, P=0.001), type of cycle (aOR=2.040, P<0.001), stage of embryos development (aOR=0.287, P<0.001), number of embryos transferred (aOR=0.184, P<0.001), female factor (tubal pathology) (aOR=0.432, P=0.031) and male factor (aOR=1.734, P=0.002) between the groups with two and three or more unexplained implantation failure. And further explored whether these differential factors had a significant negative impact on pregnancy outcome, the results showed that: for patients who had three unexplained implantation failure, in the fourth cycle of ET, the live birth rate decreased significantly with age (aOR=0.921, P<0.001), and the live birth rate of blastocyst transfer was significantly higher than that of cleavage embryo transfer (aOR=1.826, P=0.007). At their first assisted pregnancy treatment after the diagnosis of RIF according to these two different definitions, there were no significant difference in the biochemical pregnancy rate, clinical pregnancy rate, ectopic pregnancy rate and abortion rate (P>0.05), but the live birth rate (35.64% vs 42.95%, P=0.004) was significantly different. According to the definition of ‘two or more failed treatment cycles’, the live birth rate of the first ET treatment after RIF diagnosis was significantly lower than that of patients according to the definition of ‘three or more failed treatment cycles’.ConclusionFor patients with unexplained recurrent implantation failure, two implantation failure cannot be included in the diagnostic criteria of RIF. This study supports the generally accepted definition of three or more failed treatment cycles for RIF.

Abstract Background Caesarean section rates are rising worldwide. One adverse effect of caesarean section reported in some studies is an increased risk of subfertility. Only a few studies have assessed the relationship between the previous mode of delivery and in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) reproductive outcomes. In this study, we primarily investigated the impact of a history of caesarean section with or without defects on IVF/ICSI-ET outcomes compared to a vaginal delivery history. Methods This retrospective study included 834 women who had a IVF or ICSI treatment at our centre between 2015 and 2019 with a delivery history. In total, 401 women with a previous vaginal delivery (VD) were assigned to the VD group, and 433 women with a history of delivery by caesarean section were included, among whom 359 had a caesarean scar (CS) without a defect and were assigned to the CS group and 74 had a caesarean section defect (CSD) and were assigned to the CSD group. Baseline characteristics of the three groups were compared and analysed. Binary logistic regression analyses were performed to explore the association between clinical outcomes and different delivery modes. Results There were no significant differences in the live birth rate, biochemical pregnancy rate, clinical pregnancy rate, mean implantation rate or abnormal pregnancy rate between the CS and VD groups However, the live birth rate and mean implantation rate in the CSD group were significantly lower than those in the VD group (21.6 vs 36.4%, adjusted OR 0.50 [0.27–0.9]; 0.25 ± 0.39 vs 0.35 ± 0.41, adjusted OR 0.90 [0.81–0.99]). Among women aged ≤ 35 years, the subgroup analyses showed that the live birth rate, biochemical pregnancy rate, clinical pregnancy rate, and mean implantation rate in the CSD group were all significantly lower than those in the VD group (21.4 vs 45.8%, adjusted OR 0.35[0.15 ~ 0.85]; 38.1 vs 59.8%, adjusted OR 0.52[0.24–0.82]; 31.0 vs 55.6%, adjusted OR 0.43[0.19–0.92]; 0.27 ± 0.43 vs 0.43 ± 0.43, adjusted OR 0.85[0.43 ± 0.43]). For women older than 35 years, there was no statistically significant difference in any pregnancy outcome among the three groups. Conclusions This study suggested that the existence of a CS without a defect does not decrease the live birth rate after IVF or ICSI compared with a previous VD. However, the presence of a CSD in women, especially young women (age ≤ 35 years), significantly impaired the chances of subsequent pregnancy.

Abstract Backgound: IVM has emerged as a safe and promising alternative procedure to conventional in vitro fertilization (IVF) for minimizing the risk of ovarian hyperstimulation syndrome (OHSS) in patients with PCOS. Despite the comparable obstetric and perinatal outcomes, there are no definite factors known to affect the outcomes of IVM.Methods: Retrospective analysis of a total of 313 women with PCOS undergoing 427 hCG-primed IVM cycles between January 2010 and February 2016 at the Fertility Center of CHA Gangnam Medical Center, Seoul, Korea. The number of retrieved oocytes and maturation, fertilization, and implantation rates were analyzed. Results: After transferring a mean of 2.4 ± 0.5 fresh embryos, the clinical pregnancy rate was 39.1% (n = 167), and the live birth rate was 30.7% (n = 131) with the implantation rate of 20.9%. The numbers of retrieved (18.1 ± 9.7 vs. 15.6 ± 8.7, p = 0.014), fertilized (8.6 ± 5.2 vs. 6.6 ± 3.8, p < 0.001) oocytes; good-quality embryos (1.3 ± 0.9 vs. 1.0 ± 0.9, p = 0.001); and blastocyst transfer cycles (22 vs. 15, p < 0.001) were significantly higher in the live birth group than in the no live birth group. Among the factors associated with live births, retrieved oocytes had a slightly positive effect on live birth (RR = 1.03; 95% CI, 1.00, 1.06; p = 0.021).Conclusions: It seems that the number of retrieved oocytes has a favorable effect in increasing the clinical pregnancy rate and live birth rate during hCG-primed IVM procedure in women with PCOS. Physicians’ skills and cautious efforts may be required to retrieve a higher number of oocytes in IVM procedures.

Objective: The aim of this study was to compare the pregnancy outcomes of in vitro fertilization with embryo transfer between embryos cultured in a time-lapse monitoring system (TLS) and those cultured in a conventional incubator (CI).Methods: The medical records of 250 fertilized embryos from 141 patients undergoing infertility treatment with assisted reproductive technology at a tertiary hospital from June 2018 to May 2020 were reviewed. The study population was divided into TLS and CI groups at a 1 to 1 ratio (125 embryos per group). The primary outcome was the live birth rate. Results: The TLS group had a significantly higher clinical pregnancy rate (46.4% vs. 27.2%, p=0.002), implantation rate (27.1% vs. 12.0%, p=0.004), and live birth rate (32% vs. 18.4%, p=0.013) than the CI group. Furthermore, subgroup analyses of the clinical pregnancy rate and live birth rate in the different age groups favored the TLS group. However, this difference only reached statistical significance in the live birth rate in women aged over 40 years and the clinical pregnancy rate in women aged 35–40 years (p=0.048 and p=0.031, respectively). The miscarriage rate, cleavage rate, and blastocyst rate were comparable.Conclusion: TLS application improved the live birth rate, implantation rate, and clinical pregnancy rate, particularly in the advanced age group in this study, while the other reproductive outcomes were comparable. Large randomized controlled trials are needed to further explore the ramifications of these findings, especially in different age groups.

Study QuestionDoes dual trigger in freeze-all in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles improve the cumulative live-birth outcome compared with human chorionic gonadotropin (hCG) trigger?Summary AnswerDual trigger for final follicular maturation improves the cumulative pregnancy and live-birth rates compared with hCG trigger in freeze-all IVF/ICSI cycles.What Is Known AlreadyDual trigger could increase the numbers of oocytes and mature oocytes and improve pregnancy rates.Study Design, Size, DurationThis retrospective cohort analysis included data from 4438 freeze-all IVF/ICSI cycles between January 2012 and December 2017.Participants/Materials, Setting, MethodsWomen aged 20−49 years who underwent ovarian stimulation and oocyte retrieval for autologous IVF/ICSI with a freeze-all policy in our centre were enrolled. Data on number of oocytes retrieved, number of mature oocytes, clinical pregnancy rate, live-birth rate, cumulative pregnancy rate, and cumulative live-birth rate (CLBR) were assessed and compared between patients who underwent a dual trigger and hCG trigger. Multivariate logistic regression was performed to identify and adjust for factors known to independently affect the CLBR.Main Results and the Role of ChanceA total of 4438 IVF/ICSI cycles were analyzed, including 1445 cycles with single hCG trigger and 2993 cycles with dual trigger. The cumulative biochemical pregnancy rate (60.8% vs. 68.1%, P&lt;0.001; odds ratio (OR): 0.727; 95% confidence interval (CI): 0.638–0.828), cumulative clinical pregnancy rate (52.9% vs. 58.5%, P&lt;0.001; OR: 0.796; 95%CI: 0.701–0.903), and CLBR (44.3% vs. 50.5%, P&lt;0.001; OR: 0.781; 95%CI: 0.688–10.886) were all significantly lower in the hCG-trigger group compared with the dual-trigger group. The clinical pregnancy rate (48.2% vs. 58.2%, P=0.002; OR: 0.829; 95%CI: 0.737–0.934) and embryo implantation rate (34.4% vs. 38.9%, P&lt;0.001; OR: 0.823; 95%CI: 0.750–0.903) in each transfer cycle were also significantly lower in the hCG-trigger group compared with the dual-trigger group. After controlling for all potential confounding variables, the trigger method was identified as an independent factor affecting the CLBR. The OR and 95%CI for hCG trigger were 0.780 and 0.641–0.949 (P=0.013).Limitations, Reasons for CautionThe data used to analyse the effect of dual trigger on cumulative pregnancy and live-birth outcomes were retrospective, and the results may thus have been subject to inherent biases. Further prospective randomized controlled trials are required to verify the beneficial effects of dual trigger.Wider Implications of the FindingsDual trigger had a positive effect on CLBRs, suggesting that it could be used as a routine trigger method in freeze-all cycles.Study Funding/Competing Interest(s)This study was supported by grants from National Key Research and Development Program of China (2018YFC1004800), the Natural Science Program of Zhejiang (LY19H040009), the National Natural Science Foundation of China (No. 81601236).

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.
