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).

BACKGROUND: Vaccination against coronavirus disease 2019 (COVID-19) has become the primary approach in the fight against the spread of COVID-19. Studies have shown that vaccination against COVID-19 has adverse effects, particularly on human reproductive health, despite the fact that vaccination rates are still on the rise. However, few studies have reported whether vaccination affects the outcome of in vitro fertilization-embryo transfer (IVF-ET) or not. In this study, we compared the outcome of IVF-ET and the development of follicles and embryos between vaccinated and unvaccinated groups. METHODS: A single-center retrospective cohort study of 10,541 in vitro fertilization (IVF) cycles was conducted from June 2020 to August 2021. 835 IVF cycles with a history of vaccination against COVID-19 and 1670 IVF cycles that served as negative controls were selected and analyzed utilizing the Matchlt package of R software ( http://www.R-project.org/ ) and the nearest neighbor matching algorithm for propensity-matched analysis at a 1:2 ratio. RESULTS: The number of oocytes collected in the vaccinated group and the unvaccinated group were 8.00 (0, 40.00) and 9.00 (0, 77.00) ( P  = 0.073) and the good-quality embryo rates of the two groups were 0.56±0.32 and 0.56±0.31 averagely ( P  = 0.964). Clinical pregnancy rates for the vaccinated group and unvaccinated group were 42.4% (155/366) and 40.2% (328/816) ( P  = 0.486) and biochemical pregnancy rates were 7.1% (26/366) and 8.7% (71/816) ( P  = 0.355). Two other factors were analyzed in this study; vaccination among different genders and different types (inactivated vaccine or recombinant adenovirus vaccine) showed no statistically significant effect on the above outcomes. CONCLUSIONS In our findings, vaccination against COVID-19 showed no statistically significant effect on the outcomes of IVF-ET and the development of follicles and embryos, nor did the gender of the vaccinated person or the formulation of vaccines show significant effects.

OBJECTIVE: To observe the effect of conventional ovulation induction protocol and acupuncture combined with conventional ovulation induction protocol on pregnancy outcomes of frozen embryo transfer (FET) in patients with anovulatory infertility. METHODS: A total of 60 patients with anovulatory infertility were randomized into an observation group and a control group, 30 cases in each group. In the control group, conventional ovulation induction protocol was applied to prepare endometrium. On the basis of the control group, acupuncture was started on the 2nd day of menstrual cycle in the observation group，Baihui (GV 20), Mingmen (GV 4), Geshu (BL 17), Guanyuan (CV 4), Qihai (CV 6), etc. were selected, once every other day, until 1 day before transplantation. The clinical pregnancy rate, embryo implantation rate, endometrial morphology on HCG trigger day, ovulation rate and cycle cancellation rate were compared in the two groups. The endometrial thickness before treatment and on HCG trigger day, TCM symptom score before and after treatment were observed in the two groups. RESULTS: In the observation group, the embryo implantation rate and clinical pregnancy rate were higher than the control group (P<0.05), endometrial thickness and endometrial morphology on HCG trigger day were superior to the control group (P<0.05). After treatment, the TCM symptom score in the observation group was decreased compared with before treatment (P<0.05), and the variation was greater than the control group (P<0.01). CONCLUSION On the basis of the conventional ovulation induction protocol, acupuncture could enhance the embryo implantation rate and clinical pregnancy rate of FET, improve the endometrial receptivity of patients with anovulatory infertility.

For infertility treatment, the selection of in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) is decided by multiplying indicators (including fallopian tube factors, semen count, and semen motility), except for sperm morphology. In this study, we conducted a retrospective analysis, from implantation to birth, over a period of 5 years. A total of 1873 couples with primary or secondary fallopian tube factors and an increased defective sperm morphology rate (DSMR) were divided into different groups to receive IVF or ICSI cycles. By comparing the outcomes, we found that the F1 group (DSMR <96%, IVF group 1) had higher cleavage rate, biochemical pregnancy rate, clinical pregnancy rate, and live birth rate than the F3 group (DSMR >98%, IVF group 3; P < 0.05). In contrast, there was no significant difference in the ICSI subgroups. Furthermore, a comparison of the outcomes between IVF and ICSI showed that the S3 group (DSMR >98%, ICSI group 3) had higher cleavage rate (P < 0.001), biochemical pregnancy rate (P < 0.05), clinical pregnancy rate (P < 0.05) and live birth rate (P < 0.05) than the F3 group. However, the ICSI subgroup had a lower two pronuclei fertilization rate than the IVF subgroup (P < 0.05). Our data suggest that the sperm morphology should also be considered when selecting IVF or ICSI combined with other semen parameters before the first assisted reproductive technologies (ART) cycle, especially for males with severe sperm defects.

Intrauterine insemination with donor sperm (IUI-D) is an assisted reproductive technology (ART) offered to couples with definitive male infertility or risk of genetic disease transmission. Here, we sought to evaluate our practice in IUI-D and identify factors that influenced the success rate. We performed a retrospective, single-center study of all IUI-D procedures performed at Lille University Medical Center (Lille, France) between January 1, 2007, and December 31, 2017. Single and multivariate analyses with a mixed logistic model were used to identify factors associated with clinical pregnancies and live births. We included 322 couples and 1179 IUI-D procedures. The clinical pregnancy rate was 23.5%, and the live birth rate was 18.9% per IUI-D. In a multivariate analysis, the women's age was negatively associated with the live birth rate. The number of motile spermatozoa inseminated was the only factor associated with both clinical pregnancies and live births, with a chosen threshold of 0.75 million. The clinical pregnancy and live birth rates were, respectively, 17.3% and 13.0% below the number of motile spermatozoa inseminated threshold and 25.9% and 21.0% at or above the threshold (all P = 0.005). The number of motile spermatozoa inseminated was the only factor that significantly influenced both pregnancies and live-birth rates after IUI-D. Indeed, below a threshold of 0.75 million motile spermatozoa inseminated, those rates were significantly lower. Application of this number of motile spermatozoa inseminated threshold may help centers to allocate donations more effectively while maintaining reasonable waiting times for patients.

The extent of spermatogenic impairment on intracytoplasmic sperm injection (ICSI) outcomes and the risk of major birth defects have been little assessed. In this study, we evaluated the relationship between various spermatogenic conditions, sperm origin on ICSI outcomes, and major birth defects. A total of 934 infertile men attending the Center for Reproductive Medicine of Ren Ji Hospital (Shanghai, China) were classified into six groups: nonobstructive azoospermia (NOA; n = 84), extremely severe oligozoospermia (esOZ; n = 163), severe oligozoospermia (sOZ, n = 174), mild oligozoospermia (mOZ; n = 148), obstructive azoospermia (OAZ; n = 155), and normozoospermia (NZ; n = 210). Rates of fertilization, embryo cleavage, high-quality embryos, implantation, biochemical and clinical pregnancies, abortion, delivery, newborns, as well as major birth malformations, and other newborn outcomes were analyzed and compared among groups. The NOA group showed a statistically lower fertilization rate (68.2% vs esOZ 77.3%, sOZ 78.0%, mOZ 73.8%, OAZ 76.6%, and NZ 79.3%, all P < 0.05), but a significantly higher implantation rate (37.8%) than the groups esOZ (30.1%), sOZ (30.4%), mOZ (32.6%), and OAZ (31.0%) (all P < 0.05), which was similar to that of Group NZ (38.4%). However, there were no statistically significant differences in rates of embryo cleavage, high-quality embryos, biochemical and clinical pregnancies, abortions, deliveries, major birth malformations, and other newborn outcomes in the six groups. The results showed that NOA only negatively affects some embryological outcomes such as fertilization rate. There was no evidence of differences in other embryological and clinical outcomes with respect to sperm source or spermatogenic status. Spermatogenic failure and sperm origins do not impinge on the clinical outcomes in ICSI treatment.

Obtaining high-quality embryos is one of the key factors to improve the clinical pregnancy rate of assisted reproductive technologies (ART). So far, the clinical evaluation of embryo quality depends on embryo morphology. However, the clinical pregnancy rate is still low. Therefore, new indicators are needed to further improve the evaluation of embryo quality. Several studies have shown that the decrease of sperm-specific protein actin-like 7A (ACTL7A) leaded to low fertilization rate, poor embryo development, and even infertility. The aim of this study was to study whether the different expression levels of ACTL7A on sperm can be used as a biomarker for predicting embryo quality. In this study, excluding the factors of severe female infertility, a total of 281 sperm samples were collected to compare the ACTL7A expression levels of sperms with high and low effective embryo rates and analyze the correlation between protein levels and in-vitro fertilization (IVF) laboratory outcomes. Our results indicated that the ACTL7A levels were significantly reduced in sperm samples presenting poor embryo quality. Furthermore, the protein levels showed a significant correlation with fertilization outcomes of ART. ACTL7A has the potential to be a biomarker for predicting success rate of fertilization and effective embryo and the possibility of embryo arrest. In conclusion, sperm-specific protein ACTL7A has a strong correlation with IVF laboratory outcomes and plays important roles in fertilization and embryo development.

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.
