Acupuncture for in vitro fertilization in women with poor ovarian response: a systematic review

Effect of Acupuncture on Endometrial Blood Flow in Women Undergoing in vitro Fertilization Embryo Transfer: A Single Blind, Randomized Controlled Trial

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).

Good practice recommendations on add-ons in reproductive medicine†

STUDY QUESTION

Which add-ons are safe and effective to be used in ART treatment?

SUMMARY ANSWER

Forty-two recommendations were formulated on the use of add-ons in the diagnosis of fertility problems, the IVF laboratory and clinical management of IVF treatment.

WHAT IS KNOWN ALREADY

The innovative nature of ART combined with the extremely high motivation of the patients has opened the door to the wide application of what has become known as 'add-ons' in reproductive medicine. These supplementary options are available to patients in addition to standard fertility procedures, typically incurring an additional cost. A diverse array of supplementary options is made available, encompassing tests, drugs, equipment, complementary or alternative therapies, laboratory procedures, and surgical interventions. These options share the common aim of stating to enhance pregnancy or live birth rates, mitigate the risk of miscarriage, or expedite the time to achieving pregnancy.

STUDY DESIGN, SIZE, DURATION

ESHRE aimed to develop clinically relevant and evidence-based recommendations focusing on the safety and efficacy of add-ons currently used in fertility procedures in order to improve the quality of care for patients with infertility.

PARTICIPANTS/MATERIALS, SETTING, METHODS

ESHRE appointed a European multidisciplinary working group consisting of practising clinicians, embryologists, and researchers who have demonstrated leadership and expertise in the care and research of infertility. Patient representatives were included in the working group. To ensure that the guidelines are evidence-based, the literature identified from a systematic search was reviewed and critically appraised. In the absence of any clear scientific evidence, recommendations were based on the professional experience and consensus of the working group. The guidelines are thus based on the best available evidence and expert agreement. Prior to publication, the guidelines were reviewed by 46 independent international reviewers. A total of 272 comments were received and incorporated where relevant.

MAIN RESULTS AND THE ROLE OF CHANCE

The multidisciplinary working group formulated 42 recommendations in three sections; diagnosis and diagnostic tests, laboratory tests and interventions, and clinical management.

LIMITATIONS, REASONS FOR CAUTION

Of the 42 recommendations, none could be based on high-quality evidence and only four could be based on moderate-quality evidence, implicating that 95% of the recommendations are supported only by low-quality randomized controlled trials, observational data, professional experience, or consensus of the development group.

WIDER IMPLICATIONS OF THE FINDINGS

These guidelines offer valuable direction for healthcare professionals who are responsible for the care of patients undergoing ART treatment for infertility. Their purpose is to promote safe and effective ART treatment, enabling patients to make informed decisions based on realistic expectations. The guidelines aim to ensure that patients are fully informed about the various treatment options available to them and the likelihood of any additional treatment or test to improve the chance of achieving a live birth.

Clinical efficacy of acupuncture for diminished ovarian reserve: a systematic review and meta-analysis of randomized controlled trials

Objective

To evaluate the clinical efficacy of acupuncture for the treatment of diminished ovarian reserve (DOR) based on the existing randomized controlled trials (RCTs).

Methods

Nine databases from their inception to December 6th, 2022, were comprehensively searched to retrieve RCTs related to the clinical efficacy of acupuncture for the treatment of DOR. The outcomes of interest were sex hormones level and antral follicle count (AFC). Risk of Bias (RoB) was adopted to assess the quality of the included trials.

Results

A total of 13 RCTs involving 787 patients were included in this meta-analysis. The review of available evidence revealed acupuncture produced a significant efficacy in decreasing follicle-stimulating hormone (FSH) levels (SMD = -1.07, 95%CI [-1.79, -0.36], p = 0.003), FSH/LH ratio (MD = -0.31, 95%CI [-0.54, -0.09], p = 0.006) and increasing anti-Müllerian hormone (AMH) levels (SMD = 0.25, 95%CI [-0.00, 0.49], p = 0.05), along with AFC (MD = 1.87, 95%CI [0.96, 2.79], p < 0.0001) compared to controls. Compared with electro-acupuncture treatment, manual acupuncture was superior in reducing FSH levels, FSH/LH ratio, and increasing AMH levels and AFC (p < 0.05). A notable association was also seen when acupuncture was combined with traditional Chinese medicine therapy for improving FSH levels, FSH/LH ratio, and AFC (p < 0.05). Besides, a high dose of acupuncture (≥10 acupoints) was more conducive to ameliorating FSH levels, FSH/LH ratio, and AFC (p < 0.05) than a low dose of acupuncture (<10 acupoints). Substantial heterogeneity existed among studies.

Conclusion

Acupuncture may have significant clinical potential for patients with DOR in terms of improving sex hormones level and increasing AFC, although the evidence is drawn with high heterogeneity. This finding suggests that more rigorous trials conducted in diverse regions worldwide are necessary to identify the efficacy of acupuncture for patients diagnosed with DOR.

Systematic review of acupuncture to improve ovarian function in women with poor ovarian response

OBJECTIVE

To determine the effect of acupuncture in treating poor ovarian response (POR).

METHODS

We searched MEDLINE (via PubMed), EMBASE, Allied and Complementary Medicine Database, CNKI, CBM, VIP database, Wanfang Database, and relevant registration databases from inception to January 30, 2023. In this review, both Chinese and English peer-reviewed literature were included. Only randomized controlled trials (RCTs) using acupuncture as an intervention for POR patients undergoing in vitro fertilization were considered.

RESULTS

Seven clinical randomized controlled trials (RCTs) were eventually included for comparison (516 women). The quality of included studies was generally low or very low. For the meta-analysis, seven studies showed that compared with controlled ovarian hyperstimulation (COH) therapy, acupuncture combined with COH therapy could significantly increase the implantation rate (RR=2.13, 95%CI [1.08, 4.21], p=0.03), the number of oocytes retrieved (MD=1.02, 95%CI [0.72, 1.32], p<0.00001), the thickness of endometrium (MD=0.54, 95%CI [0.13, 0.96], p=0.01), and the antral follicle count (MD=1.52, 95%CI [1.08, 1.95], p<0.00001), reduce follicle-stimulating hormone (FSH) levels (MD=-1.52, 95%CI [-2.41, -0.62], p=0.0009) and improve estradiol (E₂) levels (MD=1667.80, 95%CI [1578.29, 1757.31], p<0.00001). Besides, there were significant differences in the duration of Gn (MD=0.47, 95%CI [-0.00, 0.94], p=0.05) between the two groups. However, no statistical variation was observed in improving clinical pregnancy rate (CPR), fertilization rate, high-quality embryo rate, luteinizing hormone (LH) value, anti-mullerian hormone (AMH) value, or reducing the dose of gonadotropin (Gn) values between the acupuncture plus COH therapy group and the COH therapy group.

CONCLUSION

Acupuncture combined with COH therapy is doubtful in improving the pregnancy outcome of POR patients. Secondly, acupuncture can also improve the sex hormone level of POR women, and improve ovarian function. Furthermore, more RCTs of acupuncture in POR are needed to be incorporated into future meta-analyses.

An audit of clinical outcomes following ovarian administration of platelet-rich plasma (PRP) in women with severe diminished ovarian reserve

BACKGROUND

Infertility caused by poor oocyte quality is one of the most difficult areas to manage. While oocyte donation is an effective treatment, for most women it is a treatment of last resort. Ovarian platelet-rich plasma (PRP) treatment is a relatively new adjunct therapy which has been reported to possibly improve oocyte quality and in vitro fertilisation (IVF) treatment outcomes in women with severe diminished ovarian reserve.

AIMS

To audit IVF and pregnancy outcomes following ovarian PRP treatment in a cohort of women under 45 years of age with severe diminished ovarian reserve and previous IVF treatment failure.

METHODS

An audit of 20 consecutive patients comparing embryology outcomes before and after ovarian PRP treatment, together with assessment of PRP-related pregnancies and treatment complications.

RESULTS

Overall, PRP treatment produced no significant improvement in oocyte number, but did increase the number of embryos generated compared to patients' own pre-PRP IVF cycle (zero vs two embryos, P = 0.005). In total four patients conceived viable genetically normal pregnancies in their next IVF cycle, and a further two conceived naturally within 4 months of the PRP treatment. Five of these pregnancies were in women 40 years or older, all being euploid on non-invasive pregnancy screening and viable beyond 12 weeks gestation. No operative complications were observed.

CONCLUSION

Ovarian PRP treatment appears to be low risk and may offer some promise in assisting pregnancy (natural and IVF-related), especially in women with reduced oocyte quality due to advanced maternal age. Future randomised controlled trials are urgently required to confirm this benefit.

Ovarian stimulation protocols for poor ovarian responders: a network meta-analysis of randomized controlled trials

OBJECTIVE

To evaluate the efficacy of manifold ovarian stimulation protocols for patients with poor ovarian response.

METHODS

PubMed, Embase, Cochrane Library and Web of Science were systematically searched until February 14, 2021. Primary outcomes included clinical pregnancy rate per initiating cycle and low risk of cycle cancellation. Secondary outcomes included number of oocytes retrieved, number of metaphase II (MII) oocytes, number of embryos obtained, number of transferred embryos, endometrial thickness on triggering day and estradiol (E₂) level on triggering day. The network plot, league table, rank probabilities and forest plot of each outcome measure were drawn. Therapeutic effects were displayed as risk ratios (RRs) or mean differences (MDs) with 95% confidence intervals (CIs).

RESULTS

This network meta-analysis included 15 trials on 2173 participants with poor ovarian response. Delayed start GnRH antagonist was the best regimen in terms of clinical pregnancy rate per initiating cycle (74.04% probability of being the optimal), low risk of cycle cancellation (75.30%), number of oocytes retrieved (68.67%), number of metaphase II (MII) oocytes (97.98%) and endometrial thickness on triggering day (81.97%), while for E₂ level on triggering day, microdose GnRH agonist (99.25%) was the most preferred. Regarding number of embryos obtained and number of transferred embryos, no statistical significances were found between different ovarian stimulation protocols.

CONCLUSION

Delayed start GnRH antagonist and microdose GnRH agonist were the two superior regimens in the treatment of poor ovarian response, providing favorable clinical outcomes. Future investigation is needed to confirm and enrich our findings.

Improving the health and treatment success rates of in vitro fertilization patients with traditional Chinese medicine: Need for more robust evidence and innovative approaches

Maximising access to and the success of fertility treatments should be a priority for global reproductive health, as should overall patient well-being. The demand for in vitro fertilization (IVF) and other assisted fertility treatments has increased over the past decade and is likely to further increase in years to come. Nevertheless, there is still considerable unmet demand for infertility support worldwide. Moreover, the high emotional, physical and financial burden experienced by individuals undergoing IVF cycles can be a risk for their mental and physical health, which in turn can influence treatment continuation and the likelihood of IVF success. Studies from various parts of the world show that most individuals undergoing IVF also use adjunct alternative medicines and procedures, the most common being traditional Chinese medicine (TCM). The complementary and synergistic role of TCM for individuals undergoing IVF is an area that merits further attention and research, both for its potential positive effects on IVF success rates and for its broader physical and mental health benefits. However, much of the existing evidence is not sufficiently robust or consistent for findings to be adopted with confidence. This commentary argues that much work must be done to understand the efficacy and clinical best practices for these integrated approaches. This can be achieved in part by developing more robust and clinically relevant randomized controlled trial protocols, collecting and triangulating evidence through a variety of study designs and methods, and strengthening the collection and pooling of clinic-level data.

Characteristics and Outcomes of Herbal Medicine for Female Infertility: A Retrospective Analysis of Data from a Korean Medicine Clinic During 2010-2020

Purpose

Few studies have assessed outcomes associated with the use of traditional medicine therapies to manage infertility in clinical practice. The aim of this study was to investigate the clinical characteristics of and infertility treatment effects among patients who visited a Korean medicine (KM) clinic to aid in achieving pregnancy. This study consisted of a 10-year analysis of patient records from a KM clinic.

Methods

A retrospective 10-year (2010–2020) chart analysis was performed using the medical records of infertile patients who visited a KM clinic in South Korea for fertility treatment (ICD-10, infertility symptoms: 59 codes).

Results

Of the 6194 patients who visited the clinic during the selected time frame, 1786 were female patients seeking fertility treatment to achieve pregnancy. Among the 1786 infertile women, 586 women succeeded in becoming pregnant (32.8%). Among the 586 patients who became pregnant, 476 women had received KM, 92 had been treated using KM and in vitro fertilization (IVF), and 18 had received KM and undergone intrauterine insemination (IUI). The live birth rates achieved with these treatments were 66.0%, 68.8%, and 66.7%, respectively. The most frequently prescribed medicines were Gamiboher-tang (Jiaweiwuxu-tang), Gamiguibi-tang (Jiaweiguipi-tang), and Gamidanggui-san (Jiaweidanggui-san). Additionally, the most frequent adjunct therapies administered to these patients were acupuncture and moxibustion.

Conclusion

Infertility therapies using KM may be a successful option to treat infertility when used alone or in addition to IVF and IUI. However, further pharmacological investigations and clinical trials are required to ensure the objectivity of the efficacy evaluation.

Development and Validation of Prediction Model for High Ovarian Response in In Vitro Fertilization-Embryo Transfer: A Longitudinal Study

Objective

To develop and validate a prediction model for high ovarian response in in vitro fertilization-embryo transfer (IVF-ET) cycles.

Methods

Totally, 480 eligible outpatients with infertility who underwent IVF-ET were selected and randomly divided into the training set for developing the prediction model and the testing set for validating the model. Univariate and multivariate logistic regressions were carried out to explore the predictive factors of high ovarian response, and then, the prediction model was constructed. Nomogram was plotted for visualizing the model. Area under the receiver-operating characteristic (ROC) curve, Hosmer-Lemeshow test and calibration curve were used to evaluate the performance of the prediction model.

Results

Antral follicle count (AFC), anti-Müllerian hormone (AMH) at menstrual cycle day 3 (MC3), and progesterone (P) level on human chorionic gonadotropin (HCG) day were identified as the independent predictors of high ovarian response. The value of area under the curve (AUC) for our multivariate model reached 0.958 (95% CI: 0.936-0.981) with the sensitivity of 0.916 (95% CI: 0.863-0.953) and the specificity of 0.911 (95% CI: 0.858-0.949), suggesting the good discrimination of the prediction model. The Hosmer-Lemeshow test and the calibration curve both suggested model's good calibration.

Conclusion

The developed prediction model had good discrimination and accuracy via internal validation, which could help clinicians efficiently identify patients with high ovarian response, thereby improving the pregnancy rates and clinical outcomes in IVF-ET cycles. However, the conclusion needs to be confirmed by more related studies.

A qualitative study on the experience of acupuncture treatment in infertile women

BACKGROUND

This study aimed to record and analyze the experiences of infertile women who underwent acupuncture treatment.

METHODS

This is a qualitative study in which in-depth interviews were conducted with women who underwent acupuncture as a treatment for infertility from the viewpoint of phenomenology, a method of understanding human behavior in the general human and social context, and grasping the nature of the experience in depth. The study participants were 12 women who had been receiving acupuncture treatment for infertility for more than 3 months.

RESULTS

After analyzing the statements of the participants' experiences, the main concerns regarding infertility were "embarrassed by unexpected infertility," "overwhelmed with negative feelings," "blocking and defense," "sex as a duty," and "repeatition of expectations and failures." Significant statements regarding acupuncture treatments were "body warmth," "becoming a body," "care of the mind," "last trust and hope," and "difficulties of waiting." The experience with supporter was love-hate relationships, and the experience of the children's meaning was expressed as "precious beings in life."

CONCLUSION

The results of this study suggest that acupuncture treatment for infertility in women results in positive thinking through changes in the body as well as through increased hope. Participants experienced a feeling of warmth in their bodies, regular menstrual cycle, and reduced fatigue through acupuncture treatment, indicating a state of psychological stability.

An Overview of Systematic Reviews of Acupuncture for Infertile Women Undergoing in vitro Fertilization and Embryo Transfer

Background: Currently, more and more subfertility couples are opting for combined acupuncture to improve the success rate of in vitro fertilization and embryo transfer (IVF-ET). However, the efficacy and safety of acupuncture in IVF-ET is still highly controversial.

Objectives: The purpose of this overview is to summarize evidence of essential outcomes of systematic reviews (SRs) of acupuncture in IVF-ET and evaluate their methodological quality.

Methods: We conducted a comprehensive literature search for relevant SRs in eight databases from inception to July 31, 2020, without language restriction. We evaluated the methodological quality of the included SRs by using A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR-2), which was the latest available assessment tool. The Risk of Bias in Systematic Review (ROBIS) tool was used to assess the risk of bias in SRs. We assessed the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) score to determine the strength of evidence. We excluded the overlapping randomized controlled trials (RCTs) and performed a re-meta-analysis of the primary RCTs.

Results: This review included 312 original RCT studies and 65,388 participants. By using AMSTAR-2, we found that the methodological quality of 16 SRs was critically low, because they had more than one critical weakness. Our reviews showed that although the GRADE for quality of evidence profile was suboptimal, acupuncture seemed to be beneficial in increasing the pregnancy rate. Our re-meta-analysis suggested that acupuncture was superior to sham acupuncture in improving the clinical pregnancy rate (CPR) of IVF-ET with substantial heterogeneity (RR = 1.31, 95% CI: 1.13–1.52, p = 0.0004, I² = 66%). No statistical difference was observed regarding the outcomes of live birth rate (LBR), ongoing pregnancy rate (OPR), biochemical pregnancy rate (BPR), and miscarriage rate (MR) between two groups. When compared with no adjunctive treatment groups, acupuncture improved CPR (RR = 1. 25, 95% CI: 1.11–1.42, p = 0.0003) and OPR (RR = 1. 38, 95% CI: 1.04–1.83, p = 0.03). Acupuncture was more superior than no adjunctive treatment in reducing MR (OR = 1.42, 95% CI: 1.03–1.95, p = 0.03) and BPR (RR = 1.19, 95% CI: 1.02–1.37, p = 0.02).

Conclusions: Although the evidence of acupuncture in IVF-ET is insufficient, acupuncture appears to be beneficial to increase the clinical pregnancy rate in women undergoing IVF-ET. However, there are severe heterogeneity and methodological quality defects, which limit the reliability of results. Further, high-quality primary studies are still needed.

The Effects of Acupuncture on Pregnancy Outcomes of Recurrent Implantation Failure: A Systematic Review and Meta-Analysis

Objective

To systematically evaluate the efficacy and safety of acupuncture for patients with recurrent implantation failure (RIF) undergoing in vitro fertilization-embryo transfer (IVF-ET) and hopefully provide reliable guidance for clinicians and patients.

Methods

Through searching domestic and foreign medical journals, the literature of randomized controlled trials (RCTs) of acupuncture for RIF undergoing IVF-ET was collected. RevMan 5.3 software was used for meta-analysis and Cochrane's risk of bias assessment tool was used to evaluate the quality of the included studies.

Results

Seven documents meeting the criteria were finally included. The results showed that the intervention group contributes more in outcomes including clinical pregnancy rate (RR = 1.90, 95% CI (1.51, 2.40), P < 0.05), biochemical pregnancy rate (RR = 1.59, 95% CI (1.27, 1.99), P < 0.05), embryo implantation rate (RR = 1.89, 95% CI (1.47, 2.45), P < 0.05), and endometrial thickness (MD = 1.11, 95% CI (0.59, 1.63), P < 0.05) when compared with the control group, and the difference is statistically significant. In terms of the number of embryo transfers and the type of endometrium, the difference between the acupuncture group and the control group was not statistically significant.

Conclusion

Acupuncture therapy on patients with RIF can improve the pregnancy outcome of patients. It is a relatively effective treatment with satisfactory safety and suitable for clinical application. However, as the quality of the included studies is not good enough, the conclusion of this meta-analysis should be treated with caution. More double-blind RCTs equipped with high quality and large samples are expected for the improvement of the level of evidence.

Acupuncture for "poor ovarian response" of women to controlled ovarian hyperstimulation: A protocol for meta-analysis and systematic review

BACKGROUND

Poor ovarian response (POR) is a high-incidence disease of women, which cause in vitro fertilization failure. Various treatment options have been proposed for women with POR to improve their ovarian response, but with little effect. In recent years, there is a wide range of applications of acupuncture in the process of in vitro fertilization. The meta-analysis and systematic review are designed to analyze whether acupuncture is effective for patients with POR.

METHODS

The following databases will be searched from inception to March 2020: Electronic databases consist of MEDLINE, EMBASE, Allied and Complementary Medicine Database, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, the Chinese Scientific Journal Database, and Wanfang Database. Other literature resources will also be searched including clinical trial registries, key journals, and meeting records. The results of randomized controlled trials of acupuncture therapy on POR, which are published in Chinese or English, will be embedded. The primary outcome is the clinical pregnancy rate. Data identification, data selection, data extraction, and assessment of bias risk will be completed independently by 2 or more reviewers. STATA/IC 16 will be used to perform the meta-analysis. We will use the Grading of Recommendations Assessment, Development, and Evaluation system to evaluate the quality of our evidence. A systematic narrative synthesis will be provided if the quantitative analysis is not available.

DISCUSSION

This study will provide the first meta-analysis and systematic review to evaluate the efficacy of acupuncture in treating POR. This protocol provides details to guide this study.

CONCLUSIONS

From this review may benefit POR patients or clinical decision-makers.
