OBJECTIVE: To evaluate the effect of manual acupuncture on endometrial blood flow parameters by three-dimensional (3D) power Doppler ultrasound in women undergoing in vitro fertilization embryo transfer (IVF-ET). METHODS: Seventy patients undergoing IVF-ET were equally randomized into traditional or sham acupuncture treatment group for totally 4 days (from the day of oocyte aspiration to the day of embryo transfer) of treatment by random envelope method at the Reproductive Medicine Center and Outpatient Department of Integrated Traditional Chinese and Western Medicine, Tongji Hospital, Tongji Medicine College, Huazhong University of Science and Technology from January 2013 to December 2015. Patients in the traditional acupuncture group accepted traditional acupuncture methods with manual acupuncture, and Zhongji (CV3), Qihai (CV 6), Sanyinjiao (SP6), Taichong (LR 3), Tianshu (ST 25), Guilai (ST 29) and Zusanli (ST 36) were chosen. Patients at the sham acupuncture group accepted shallow acupuncture methods at 4 non-meridian points at each shoulder and upper arm. Outcome measures included endometrial ultrasonic indices such as vascularization index (VI), flow index (FI) and vascularization flow index (VFI), endometrial thickness and volume, subendometrial VI (sVI), subendometrial FI (sFI), subendometrial VFI (sVFI), implantation rate, clinical pregnancy rate, abortion rate, live birth rate and number of live births. RESULTS: Finally, 34 patients in the traditional acupuncture group and 35 in the sham acupuncture group completed this trial. VI, FI and VFI of the traditional acupuncture group were significantly higher than those in the sham acupuncture group (P<0.05). No significant differences were found in endometrial thickness, endometrial volume, sVI, sFI, sVFI, implantation rate, clinical pregnancy rate, abortion rate, live birth rate and number of live births (P>0.05). CONCLUSIONS Manual acupuncture performed after oocyte aspiration and before transplantation improved the endometrial blood flow parameters VI, RI and VFI in women who underwent IVF-ET, instead of sVI, sFI and sVFI. Therefore, acupuncture might be beneficial in women undergoing IVF-ET by increasing endometrial blood flow and endometrial receptivity. (Registration No. ChiCTR2100053354).

OBJECTIVES: To evaluate the report quality, methodological quality and evidence quality of the systematic reviews and meta-analyses (SRs/MAs) of acupuncture for in vitro fertilization-embryo transfer (IVF-ET). METHODS: The SRs/MAs of acupuncture for IVF-ET were searched electronically from databases of CNKI, Wanfang, VIP, SinoMed, PubMed, Embase, Cochrane Library, from inception of each database to September 27th, 2022. Two reviewers independently screened the literature and extracted the data. Using PRISMA statement, the AMSTAR 2 scale and the GRADE system, the report quality, methodological quality and evidence quality of the included SRs/MAs were assessed. RESULTS: A total of 28 SRs/MAs were included, with PRISMA scores ranging from 8.5 points to 27 points. The problems of report quality focused on protocol and registration, retrieval, risk of bias in studies, additional analysis, limitations and funding. The methodological quality of included studies was generally low, reflecting on items 2, 3, 7, 10, 12 and 16. A total of 85 outcome indexes were included in the GRADE system for evidence grade evaluation. Most of the evidences were low or very low in quality. The reasons for the downgrade were related to study limitations, inconsistency, imprecision and publication bias. CONCLUSIONS Acupuncture therapy improves the outcomes of IVF-ET, but the methodological quality and evidence quality of related SRs/MAs are low. It is recommended to conduct more high-quality studies in the future to provide more reliable evidences.

BACKGROUND: Currently, more and more infertility couples are opting for combined acupuncture to improve success rate of in vitro fertilization (IVF). However, evidence from acupuncture for improving IVF pregnancy outcomes remains a matter of debate. OBJECTIVE: To quantitatively summarized the evidence of the efficacy of acupuncture among women undergoing IVF by means of systematic review and meta-analysis. METHODS: Four English (PubMed, Web of Science, EMBASE, and Cochrane Register of Controlled Clinical Trials) and Four Chinese databases (Wanfang Databases, Chinese National Knowledge Infrastructure, Chinese Science and Technology Periodical Database, and SinoMed) were searched from database inception until July 2, 2023. Randomized controlled trials (RCTs) that evaluated the acupuncture's effects for women undergoing IVF were included. The subgroup analysis was conducted with respect to the age of participants, different acupuncture types, type of control, acupuncture timing, geographical origin of the study, whether or not repeated IVF failure, and acupuncture sessions. Sensitivity analyses were predefifined to explore the robustness of results. The primary outcomes were clinical pregnancy rate (CPR) and live birth rate (LBR), and the secondary outcomes were ongoing pregnancy rate and miscarriage rate. Random effects model with I² statistics were used to quantify heterogeneity. Publication bias was estimated by funnel plots and Egger's tests. RESULTS: A total of 58 eligible RCTs representing 10,968 women undergoing IVF for pregnant success were identifified. Pooled CPR and LBR showed a signifificant difference between acupuncture and control groups [69 comparisons, relative risk (RR) 1.19, 95% confifidence intervals (CI) 1.12 to 1.25, I²=0], extremely low evidence; 23 comparisons, RR 1.11, 95%CI 1.02 to 1.21, I²=14.6, low evidence, respectively). Only transcutaneous electrical acupoint stimulation showed a positive effect on both CPR (16 comparisons, RR 1.17, 95%CI 1.06 to 1.29; I²=0, moderate evidence) and LBR (9 comparisons, RR 1.20, 95%CI 1.04 to 1.37; I²=8.5, extremely low evidence). Heterogeneity across studies was found and no studies were graded as high-quality evidence. CONCLUSION Results showed that the convincing evidence levels on the associations between acupuncture and IVF pregnant outcomes were relatively low, and the varied methodological design and heterogeneity might inflfluence the fifindings.

OBJECTIVE: To explore the effects of Zishen Yutai Pills (ZYPs) on the quality of oocytes and embryos, as well as pregnancy outcomes in patients with diminished ovarian reserve (DOR) receiving in vitro fertilization-embryo transfer (IVF-ET). The possible mechanisms, involving the regulation of bone morphogenetic protein 15 (BMP15) and growth differentiation factor 9 (GDF9), were also investigated. METHODS: A total of 120 patients with DOR who underwent their IVF-ET cycle were randomly allocated to 2 groups in a 1:1 ratio. The patients in the treatment group (60 cases) received ZYPs from the mid-luteal phase of the former menstrual cycle by using gonadotropin-releasing hormone (GnRH) antagonist protocol. The patients in the control group (60 cases) received the same protocol but without ZYPs. The primary outcomes were the number of oocytes retrieved and high-quality embryos. Secondary outcomes included other oocyte or embryo indices as well as pregnancy outcomes. Adverse events were assessed by comparison of the incidence of ectopic pregnancy, pregnancy complications, pregnancy loss, and preterm birth. Contents of BMP15 and GDF9 in the follicle fluids (FF) were also quantified with enzyme-linked immunosorbent assay. RESULTS: Compared with the control group, the numbers of oocytes retrieved and high-quality embryos were significantly increased in the ZYPs group (both P<0.05). After treatment with ZYPs, a significant regulation of serum sex hormones was observed, including progesterone and estradiol. Both hormones were up-regulated compared with the control group (P=0.014 and 0.008), respectively. No significant differences were observed with regard to pregnancy outcomes including implantation rates, biochemical pregnancy rates, clinical pregnancy rates, live birth rates, and pregnancy loss rates (all P>0.05). The administration of ZYPs did not increase the incidence of adverse events. The expressions of BMP15 and GDF9 in the ZYPs group were significantly up-regulated compared with the control group (both P<0.05). CONCLUSIONS ZYPs exhibited beneficial effects in DOR patients undergoing IVF-ET, resulting in increments of oocytes and embryos, and up-regulation of BMP15 and GDF9 expressions in the FF. However, the effects of ZYPs on pregnancy outcomes should be assessed in clinical trials with larger sample sizes (Trial reqistration No. ChiCTR2100048441).

Infertility affects 10%-15% of couples worldwide. Of all infertility cases, 20%-70% are due to male factors. In the past, men with severe male factor (SMF) were considered sterile. Nevertheless, the development of intracytoplasmic sperm injection (ICSI) drastically modified this scenario. The advances in assisted reproductive technology (ART), specifically regarding surgical sperm retrieval procedures, allowed the efficacious treatment of these conditions. Yet, before undergoing ICSI, male factor infertility requires careful evaluation of clinical and lifestyle behavior together with medical treatment. Epidemiologically speaking, women whose male partner is azoospermic tend to be younger and with a better ovarian reserve. These couples, in fact, are proposed ART earlier in their life, and for this reason, their ovarian response after stimulation is generally good. Furthermore, in younger couples, azoospermia can be partially compensated by the efficient ovarian response, resulting in an acceptable fertility rate following in vitro fertilization (IVF) techniques. Conversely, when azoospermia is associated with a reduced ovarian reserve and/or advanced maternal age, the treatment becomes more challenging, with a consequent reduction in IVF outcomes. Nonetheless, azoospermia seems to impair neither the euploidy rate at the blastocyst stage nor the implantation of euploid blastocysts. Based on the current knowledge, the assessment of male infertility factors should involve: (1) evaluation - to diagnose and quantify seminologic alterations; (2) potentiality - to determine the real possibilities to improve sperm parameters and/or retrieve spermatozoa; (3) time - to consider the available "treatment window", based on maternal age and ovarian reserve. This review represents an update of the definition, prevalence, causes, and treatment of SMF in a modern ART clinic.

OBJECTIVES: To identify, examine and summarize the available evidence on the effectiveness and safety of acupuncture for in vitro fertilisation (IVF) outcomes. METHODS: Eight electronic databases, including PubMed, EMBASE, Cochrane Database of Systematic Review, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Wanfang Database, Chinese Biomedical Database and VIP Database, were searched, supplemented by manual searches. Two researchers independently conducted the literature screening, data extraction, and methodological quality assessments. A narrative description was provided to show the general information and specific characteristics of the included studies. A bubble plot was used to visually display the overall effects of acupuncture on IVF outcomes. RESULTS: Eighty-two studies were identified, including 64 primary studies and 18 systematic reviews. Transcutaneous electrical acupoint stimulation, electric acupuncture and manual acupuncture were applied in most studies and compared with no acupuncture, sham acupuncture and placebo acupuncture control groups. Sixty-three (98.4%) primary studies reported clinical pregnancy rate, and positive effects of acupuncture were found in 34 studies (54.0%). Live birth rate was reported in only 18 (28.1%) primary studies, of which 10 (55.6%) showed positive results. In addition, only 8 and 2 systematic reviews showed that acupuncture could increase clinical pregnancy events and live birth events, respectively. However, none of these reviews was of high methodological quality. CONCLUSIONS Available evidence suggests that acupuncture therapy could improve clinical pregnancy rates. However, whether acupuncture could increase live birth events was difficult to determine based on the few studies that have reported this outcome indicator. Furthermore, the methodological quality of most systematic reviews was assessed as critically low or low. Studies with a rigorous design and standardized implementation should be performed to refine the available evidence.

OBJECTIVE: To observe the effect of acupuncture on endometrium and pregnancy outcomes in patients with polycystic ovary syndrome (PCOS) infertility undergoing in vitro fertilization-embryo transfer (IVF-ET). METHODS: Eighty-three patients were randomly assigned to observation group (40 cases) and control group (43 cases) according to the random numbers generated by SPSS software. The patients of the two groups received GnRH agonist long protocol as a routine treatment. In the observation group, acupuncture was given at two acupoint groups for 30 min once every other day. Group 1 included Guanyuan (CV 4), Qihai (CV 6), Zhongji (CV 3), bilateral acupoints Zigong (EX-CA1). Group 2 included Mingmen (GV 4), Yaoyangguan (GV 3), bilateral Shenshu (BL 23) and Ciliao (BL 32). The two groups of acupoints were used alternately. The whole needling process was performed at the time of ovulation induction until the transplantation day and consisted of 3 courses, while the control group did not receive acupuncture interventions. The Gn dosage and Gn stimulation time, endometrial thickness and type (A, B, and C), serum oestradiol (E2) and progesterone (P) levels on the day of injection of human chorionic gonadotropin (hCG), clinical pregnancy rate, as well as live birth rate were observed. Adverse reactions were also be recorded. All patients were followed up for the pregnant rate 14 days after IVF-ET and live birth rate after pregnancy. All adverse reactions (AEs) of acupuncture were recorded during the trial. RESULTS: The Gn dosage and Gn stimulation time in the observation group were lower in the observation group than in the control group (P<0.01). The proportion of type A endometrium in the observation group were higher than that in the control group (P<0.05). The serum E₂ and P levels on the day of hCG injection was lower and the clinical pregnancy rate was higher in the observation group compared to those in the control group (P<0.05). There was no serious AEs during this trial. CONCLUSION Acupuncture can improve the proportion of type A endometrium, regulate the levels of serum E₂ and P on the day of hCG injection, and improve the pregnancy rate in patients with PCOS infertility undergoing IVF-ET.

OBJECTIVE: To assess the value of preimplantation genetic test (PGT) based on next generation sequencing (NGS) for achieving pregnancy for 71 couples with one partner carrying a reciprocal or Robertsonian translocation. METHODS: Following blastocyst biopsy, whole genome of single cell was amplified, and PGT was performed by NGS. The subjects included 60 couples with one partner carrying a reciprocal translocation and 11 with one partner carrying a Robertsonian translocation. The results of PGT, implantation and prenatal diagnosis for all of the couples were analyzed. RESULTS: In total 301 embryos were obtained for the 71 couples through 92 ovulation cycles, 287 (95.3%) of which were successfully diagnosed by NGS. Eighty-five euploidy embryos were identified for the reciprocal translocation carrier group. In 18 cycles, no euploid embryo was obtained. Cancellation rate for the cycles was 19.5%. For reciprocal translocation carrier group and Robertsonian translocation carrier group, the rates for implantation, early abortion, and clinical pregnancy were 89.3% (42/47), 25.5% (12/47), 63.8% (30/47), and 88.8% (8/9), 22.2% (2/9), and 66.6% (6/9), respectively. The result of prenatal diagnosis was consistent with the that of PGT. CONCLUSION PGT based on NGS can effectively identify euploid embryos and reduce recurrent abortions and termination of pregnancies, achieving a satisfactory rate for clinical pregnancy.

OBJECTIVE: To compare laboratory and clinical outcomes of fertilization-embryo transfer (IVF-ET) in patients with endometriosis using antagonist protocol, long agonist protocol or prolonged agonist protocol. METHODS: Totally 313 patients with endometriosis were recruited in Reproductive Centers of the Second Affiliated Hospital of Zhejiang University School of Medicine,Jiaxing Women and Children's Hospital,and Ningbo Women and Children's Hospital from April 2017 to October 2018, including 81 patients treated with antagonist protocol (antagonist group), 148 treated with long agonist protocol (long agonist group) and 84 treated with prolonged agonist protocol (prolonged agonist group). The clinical and laboratory data of the patients were retrospectively analyzed to investigate the effect of ovarian stimulation protocols on the IVF-ET outcomes of patients with endometriosis. RESULTS: The average age in the antagonist group patients was significantly higher than those in the other two groups (all <0.05),and anti-mullerian hormone (AMH) level and antral follicle numbers were significantly lower than those in the other two groups (all <0.01). The numbers of average retrieved oocyte, fertilized oocyte and available embryo in the antagonist group were significantly lower than those in the long agonist group (all <0.05), but were similar with those in the prolonged agonist group (all >0.05). Fertilization rate and available embryo rate were comparable among the three groups (all >0.05). Considering analysis per cycle with embryo transfer, the human chorionic gonadotrophin (HCG) positive rate, clinical pregnancy rate and total implantation rate showed no significant difference among the three groups (all >0.05). The implantation rate after fresh embryo transfer in the antagonist group was lower than that in the long agonist group (<0.05), but was similar with that in the prolonged agonist group (>0.05). While the implantation rate of freeze-thaw embryo transfer showed a higher trend in the antagonist group, but there was no significant difference (>0.05). The patients were further divided into diminished and normal ovarian reserve subgroups, the per cycle with embryo transfer, the HCG positive rate, clinical pregnancy rate and total implantation rate still showed no significant difference between two subgroups (all >0.05), no matter in which ovarian stimulation protocol groups. Besides, in women with diminished ovarian reserve, the available embryo rate in antagonist group was significantly higher than that in the long agonist group (<0.05). The amount and duration of Gn application in antagonist group were significantly lower than those in long and prolonged agonist groups (all <0.05). CONCLUSIONS Patients with endometriosis who used the antagonist protocol in IVF procedure could reduce the cost and time of Gn treatment, when combined with frozen-embryo transfer strategy the antagonist protocol has comparable clinical pregnancy outcome with long or prolonged agonist protocol, especially in those with diminished ovarian reserve, the higher available embryo rate can be achieved.

Antisperm antibodies (ASAs) are assumed to be a possible causative factor for male infertility, with ASAs detected in 5%-15% of infertile men but in only 1%-2% of fertile ones. It remains unclear whether ASAs have an adverse effect on the outcome of in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). This study investigated differences in the rates of fertilization, pregnancy, and live births associated with serum ASA-positive and ASA-negative men following IVF or ICSI. Five hundred and fifty-four consecutive infertile couples undergoing IVF (n = 399) or ICSI (n = 155) were included. The two-sample two-sided t-test and Chi-square or Fisher's exact test was used for statistical analysis. Lower rates of fertilization (41.7% vs 54.8%, P = 0.03), good embryos (18.9% vs 35.2%, P = 0.00), pregnancy (38.5% vs 59.4%, P = 0.00), and live births (25.8% vs 42.5%, P = 0.00) were observed in men of the IVF group with a positive serum ASA than in those with a negative ASA. ASA positivity/negativity correlated with pregnancy rates (P = 0.021, odds ratio [OR]: 0.630, 95% confidence interval [CI]: 0.425-0.932) and live birth rates (P = 0.010, OR: 1.409, 95% CI: 1.084-1.831) after controlling for the female serum follicle-stimulating hormone level and the couple's ages at IVF. Women coupled with ASA-positive men had lower live birth rates with IVF than with ICSI (25.8% and 47.4%, respectively; P = 0.07). Women coupled with ASA-positive men had lower rates of pregnancy and live births following IVF than those coupled with ASA-negative men but had a similar outcome with ICSI.
