Abstract
Globally, public health interventions have resulted in a 30-year increase in women's life expectancy. However, women's health has not increased when socioeconomic status is ignored. Women's health has become a major public health concern, for those women from developing countries are still struggling with infectious and labor-related diseases, and their counterparts in developed countries are suffering from physical and psychological disorders. In recent years, complementary and alternative medicine has attracted wide attentions with regards to maintaining women's health. Acupuncture, a crucial component of traditional Chinese medicine, has been used to treat many obstetric and gynecological diseases for thousands of years due to its analgesic and anti-inflammatory effects and its effects on stimulating the sympathetic/parasympathetic nervous system. To fully understand the mechanism through which acupuncture exerts its effects in these diseases would significantly extend the list of available interventions and would allow for more reasonable advice to be given to general practitioners. Therefore, by searching PubMed and CNKI regarding the use of acupuncture in treating obstetric and gynecological diseases, we aimed to summarize the proven evidence of using acupuncture in maintaining women's health by considering both its effectiveness and the underlying mechanisms behind its effects.

Abstract
BACKGROUND Transvaginal oocyte retrieval is frequently followed by adverse events related to anesthesia and the procedure. Some research showed that transcutaneous electrical acupoint stimulation (TEAS) can relieve intraoperative pain and postoperative nausea. OBJECTIVE This study examined whether TEAS can alleviate pain and relieve adverse symptoms after oocyte retrieval. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS Altogether 128 patients were randomly divided into the TEAS group and the mock TEAS group. The two groups received a 30-minute-long TEAS or mock TEAS treatment that began 30 min after oocyte retrieval. MAIN OUTCOME MEASURES The primary outcome was the visual analog scale (VAS) pain score. Secondary outcomes were pressure pain threshold, McGill score, pain rating index (PRI), present pain intensity (PPI), VAS stress score, VAS anxiety score, and postoperative adverse symptoms. RESULTS The baseline characteristics of the two groups were comparable (P > 0.05). The VAS pain scores of the TEAS group were lower than those of the mock TEAS group at 60 and 90 min after oocyte retrieval (P < 0.05). The McGill score, PRI and PPI in the TEAS group were significantly lower than those in the control group at 60 min after oocyte retrieval (P < 0.05). However, the two groups had equivalent beneficial effects regarding the negative emotions, such as nervousness and anxiety (P > 0.05). The TEAS group was superior to the mock TEAS group for relieving postoperative adverse symptoms (P < 0.05). CONCLUSION TEAS treatment can relieve postoperative pain and postoperative adverse symptoms for patients undergoing oocyte retrieval.

Systematic Review and Meta-Analysis of Acupuncture for Pain Management in Women Undergoing Transvaginal Oocyte Retrieval. J Pain Res 2021; 14:2833-2849. [PMID: 34526816 PMCID: PMC8437417 DOI: 10.2147/jpr.s319923] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Accepted: 07/08/2021] [Indexed: 12/13/2022] Open
Abstract
Objective To obtain evidence-based conclusions about the effect of acupuncture on pain relief in women undergoing oocyte retrieval, the results of randomized controlled trials (RCTs) that met the criteria were assessed on the Pain Assessment Scale and pregnancy indicators. Search Methods References were retrieved in MEDLINE, EMBASE, CNKI database, CBM database, VIP database, and Wanfang database from inception to June 26, 2021. Unpublished ongoing trials were searched in the Clinical Trials Registries. This review included RCTs that investigated the acupuncture analgesic effects during oocyte retrieval in women undergoing in vitro fertilization. Results Fourteen RCTs (2503 women in total) with six types of comparisons were finally included. The quality of concluding evidence was generally low or very low. Performance bias and outcome assessment bias was the main risk of bias of the included studies. Acupuncture combined with conscious sedation and analgesia (CSA) was associated with less intraoperative (SMD=−1.03; 95% CI: −1.71 to −0.36) and postoperative (SMD = −1.11; 95% CI: −1.51 to −0.71) pain compared to receive CSA alone in oocyte retrieval. Acupuncture with non-steroidal anti-inflammatory drugs (NSAIDs) was more effective than using NSAIDs alone for postoperative analgesia (MD = −1.76; 95% CI: −2.08 to −1.44). Conclusion Acupuncture complex analgesic therapy is more effective than utilizing CSA or NSAIDs alone. Furthermore, there is no significant consensus on whether there is an analgesic effect of applying acupuncture alone during oocyte retrievals, which needs further research. The overall results should be interpreted with caution due to the high risk of bias/low-GRADE scores among these studies. Protocol and Registration PROSPERO registration number: CRD42020170095.

Abstract
BACKGROUND Pain during oocyte retrieval, which can make the in-vitro fertilization process an unpleasant experience, is becoming a common problem. Although there are many analgesic methods available in the clinical setting, they are not therapeutically equivalent, and some are associated with varying adverse reactions. In recent years, acupuncture analgesia has been used in the perioperative period of oocyte retrieval because of its perceived efficacy and safety. The purpose of this systematic review and meta-analysis is to provide evidence that acupuncture is effective in the treatment of vaginal oocyte retrieval pain. METHODS Electronic searches of the following six databases will be conducted by two qualified reviewers: MEDLINE, EMBASE, China National Knowledge Infrastructure, Chinese Biomedical Medicine database, VIP database and Wanfang database. Three clinical trial registries will also be searched: World Health Organization International Clinical Trial Registry Platform, Chinese Clinical Trial Registry, Cochrane Central Register of Controlled Trials and ClinicalTrials.Gov. All searches will cover the period from inception of the database/registry to March 2020 and will be limited to publications in English and Chinese. Data identification, data selection, data extraction, and bias risk assessment will be conducted independently by3ν two or more qualified reviewers, including those who selected the studies. Visual analogue scale scores will be calculated as the primary outcome. Secondary outcomes will include results of other subjective pain rating scales, including Likert scales or other defined numerical or non-numerical scales, self-assessed by patients before, during, and after oocyte retrieval. We will use STATA software (Version 16) to perform meta-analyses, and the Grading of Recommendations, Assessment, Development and Evaluations framework to grade the quality of evidence. If quantitative analysis is not available, a systematic narrative synthesis will be provided. PROSPERO REGISTRATION NUMBER CRD42020170095.

Abstract
OBJECTIVES To analyze a clip from the program ? Acupuncture, osteopathy, hypnosis: do complementary medicines have superpowers ? about acupuncture as an anesthetic for surgical procedures in China. To propose a rational explanation for the phenomena observed. To describe the processes leading a public service broadcasting channel to offer this type of content at prime time and the potential consequences in terms of public health. METHOD Analysis using critical thinking attitudes and skills, along with a bibliographical search of Medline, Google Scholar and Cochrane Library databases. RESULTS The information delivered in the television clip is ambiguous. It does not allow the viewer to form an informed opinion on the relevance of acupuncture as an anesthetic for surgical procedures. It is reasonable to assume that the clip shows surgery performed with undisclosed epidural anesthesia coupled with mild intravenous anesthesia, sometimes performed in other countries. What needs to be highlighted here is the overestimation of acupuncture added to the protocol. The media tend to exaggerate the risks and expected effects of the treatments they report on, which can lead patients to turn to unproven therapies. CONCLUSION Broadcasting such a clip at prime time underlines the urgent need for the public and all health professionals to be trained in sorting and critically analyzing health information.

Abstract
BACKGROUND Various methods of conscious sedation and analgesia (CSA) have been used during oocyte retrieval for assisted reproduction. The choice of agent has been influenced by the quality of sedation and analgesia and by concerns about possible detrimental effects on reproductive outcomes. OBJECTIVES To assess the effectiveness and safety of different methods of conscious sedation and analgesia for pain relief and pregnancy outcomes in women undergoing transvaginal oocyte retrieval. SEARCH METHODS We searched; the Cochrane Gynaecology and Fertility specialised register, CENTRAL, MEDLINE, Embase, PsycINFO and CINAHL, and trials registers in November 2017. We also checked references, and contacted study authors for additional studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing different methods and administrative protocols for conscious sedation and analgesia during oocyte retrieval. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Our primary outcomes were intraoperative and postoperative pain. Secondary outcomes included clinical pregnancy, patient satisfaction, analgesic side effects, and postoperative complications. MAIN RESULTS We included 24 RCTs (3160 women) in five comparisons. We report the main comparisons below. Evidence quality was generally low or very low, mainly owing to poor reporting and imprecision.1. CSA versus other active interventions.All evidence for this comparison was of very low quality.CSA versus CSA plus acupuncture or electroacupunctureData show more effective intraoperative pain relief on a 0 to 10 visual analogue scale (VAS) with CSA plus acupuncture (mean difference (MD) 1.00, 95% confidence interval (CI) 0.18 to 1.82, 62 women) or electroacupuncture (MD 3.00, 95% CI 2.23 to 3.77, 62 women).Data also show more effective postoperative pain relief (0 to 10 VAS) with CSA plus acupuncture (MD 0.60, 95% CI -0.10 to 1.30, 61 women) or electroacupuncture (MD 2.10, 95% CI 1.40 to 2.80, 61 women).Evidence was insufficient to show whether clinical pregnancy rates were different between CSA and CSA plus acupuncture (odds ratio (OR) 0.61, 95% CI 0.20 to 1.86, 61 women). CSA alone may be associated with fewer pregnancies than CSA plus electroacupuncture (OR 0.22, 95% CI 0.07 to 0.66, 61 women).Evidence was insufficient to show whether rates of vomiting were different between CSA and CSA plus acupuncture (OR 1.64, 95% CI 0.46 to 5.88, 62 women) or electroacupuncture (OR 1.09, 95% CI 0.33 to 3.58, 62 women).Trialists provided no usable data for other outcomes of interest.CSA versus general anaesthesia Postoperative pain relief was greater in the CSA group (0 to 3 Likert: mean difference (MD) 1.9, 95% CI 2.24 to 1.56, one RCT, 50 women).Evidence was insufficient to show whether groups differed in clinical pregnancy rates (OR 1.00, 95% CI 0.43 to 2.35, two RCTs, 108 women, I2 = 0%).Evidence was insufficient to show whether groups differed in rates of vomiting (OR 0.46, 95% CI 0.08 to 2.75, one RCT, 50 women) or airway obstruction (OR 0.14, 95% CI 0.02 to 1.22, one RCT, 58 women). Fewer women needed mask ventilation in the CSA group (OR 0.05, 95% CI 0.01 to 0.20, one RCT, 58 women).Evidence was also insufficient to show whether groups differed in satisfaction rates (OR 0.66, 95% CI 0.11 to 4.04, two RCTs, 108 women, I2 = 34%; very low-quality evidence).Trialists provided no usable data for outcomes of interest.2. CSA + paracervical block (PCB) versus other interventions.CSA + PCB versus electroacupuncture + PCB Intraoperative pain scores were lower in the CSA + PCB group (0 to 10 VAS: MD -0.66, 95% CI -0.93 to -0.39, 781 women, I2 = 76%; low-quality evidence).Evidence was insufficient to show whether groups differed in clinical pregnancy rates (OR 0.96, 95% CI 0.72 to 1.29, 783 women, I2 = 9%; low-quality evidence).Trialists provided no usable data for other outcomes of interest.CSA + PCB versus general anaesthesiaEvidence was insufficient to show whether groups differed in postoperative pain scores (0 to 10 VAS: MD 0.49, 95% CI -0.13 to 1.11, 50 women; very low-quality evidence).Evidence was insufficient to show whether groups differed in clinical pregnancy rates (OR 0.70, 95% CI 0.22 to 2.26, 51 women; very low-quality evidence).Trialists provided no usable data for other outcomes of interest.CSA + PCB versus spinal anaesthesiaPostoperative pain scores were higher in the CSA + PCB group (0 to 10 VAS: MD 1.02, 95% CI 0.48 to 1.56, 36 women; very low-quality evidence).Evidence was insufficient to show whether groups differed in clinical pregnancy rates (OR 0.93, 95% CI 0.24 to 3.65, 38 women; very low-quality evidence).Trialists provided no usable data for other outcomes of interest.CSA + PCB versus PCBEvidence was insufficient to show whether groups differed in clinical pregnancy rates (OR 0.93, 95% CI 0.44 to 1.96, 150 women; low-quality evidence) or satisfaction (OR 1.63, 95% CI 0.68 to 3.89, 150 women, low-quality evidence).Trialists provided no usable data for other outcomes of interest.CSA + PCB versus CSA only Evidence was insufficient to show whether groups differed in clinical pregnancy rates (OR 0.62, 95% CI 0.28 to 1.36, one RCT, 100 women; very low-quality evidence). Rates of postoperative nausea and vomiting were lower in the CS + PCB group (OR 0.42, 95% CI 0.18 to 0.97, two RCTs, 140 women, I2 = 40%; very low-quality evidence).Trialists provided no usable data for other outcomes of interest. AUTHORS' CONCLUSIONS The evidence does not support one particular method or technique over another in providing effective conscious sedation and analgesia for pain relief during and after oocyte retrieval. Simultaneous use of sedation combined with analgesia such as the opiates, further enhanced by paracervical block or acupuncture techniques, resulted in better pain relief than occurred with one modality alone. Evidence was insufficient to show conclusively whether any of the interventions influenced pregnancy rates. All techniques reviewed were associated with a high degree of patient satisfaction. Women's preferences and resource availability for choice of pain relief merit consideration in practice.

Abstract
Background: Various sedative and analgesic techniques have been used for pain relief during oocyte retrieval which is the most painful part of in vitro fertilization (IVF) procedures. Aim: This study aimed at comparing dexmedetomidine and midazolam for conscious sedation in women undergoing transvaginal oocyte retrieval during an IVF program. Settings and Design: Prospective randomized double-blinded comparative study. Patients and Methods: Fifty-two patients undergoing oocyte retrieval in their first IVF cycle were randomly allocated into two equal groups. The intervention started with giving fentanyl1 mcg/kg intravenous (IV) followed by paracervical block in both groups. Then, subjects in group (D) received dexmedetomidine at a loading dose of 1 μg/kg IV over 10 min followed by 0.5 μg/kg/h infusion until Ramsay Sedation Scale (RSS) reached 3–4. Patients in group (M) received a loading dose of midazolam 0.06 mg/kg IV over 10 min followed by 0.5 mg incremental doses until RSS reached 3–4. Statistical Analysis: Statistical analysis was performed using SPSS program version 19 and EP 16 program. Results: Visual analog scale scores significantly decreased in group D than group M at 5 and 10 min during the procedure (P = 0.03 and 0.01, respectively), and at 20 min during postanesthesia care unit (PACU) time (P = 0.04). Intraoperative rescue sedation by propofol and postoperative rescue analgesia by acetaminophen showed a highly significant decrease (P < 0.01) in group D compared with group M. Furthermore, the time of PACU stay was significantly less (P < 0.01) in group D (49.03 ± 12.8 min) compared to group M (62.5 ± 18.34 min). Although significant bradycardia was noted in group D (23% of patients) during the procedure (P = 0.02), no cases were reported in group M. Patient satisfaction was significantly higher in group D (P < 0.1). Conclusion: Dexmedetomidine is an effective analgesic alternative to midazolam during oocyte retrieval for IVF. It offered not only a shorter PACU stay without significant side effects, but also better overall patient satisfaction scores.

Abstract
Patients undergoing IVF may receive either acupuncture or whole-systems traditional Chinese medicine (WS-TCM) as an adjuvant IVF treatment. WS-TCM is a complex intervention that can include acupuncture, Chinese herbal medicine, dietary, lifestyle recommendations. In this retrospective cohort study, 1231 IVF patient records were reviewed to assess the effect of adjuvant WS-TCM on IVF outcomes compared among three groups: IVF with no additional treatment; IVF and elective acupuncture on day of embryo transfer; or IVF and elective WS-TCM. The primary outcome was live birth. Of 1069 non-donor cycles, WS-TCM was associated with greater odds of live birth compared with IVF alone (adjusted odds ratio [AOR] 2.09; 95% confidence interval [CI] 1.36 to 3.21), or embryo transfer with acupuncture only (AOR 1.62; 95% CI 1.04 to 2.52). Of 162 donor cycles, WS-TCM was associated with increased live births compared with all groups (odds Ratio [OR] 3.72; 95% CI 1.05 to 13.24, unadjusted) or embryo transfer with acupuncture only (OR 4.09; 95% CI: 1.02 to 16.38, unadjusted). Overall, IVF with adjuvant WS-TCM was associated with greater odds of live birth in donor and non-donor cycles. These results should be taken cautiously as more rigorous research is needed.

Abstract
Spermatogenesis is regulated by a cascade of steroid regulated genes in the testis. Recent studies suggested that acupuncture may improve fertility in men with abnormal semen parameters. Yet, the underlying mechanisms in which acupuncture enhances spermatogenesis remain largely unknown. Here we used a scrotal heat-treated rat model to study the effect of electroacupuncture (EA) on recovery of spermatogenesis. In this model, spermatogenesis was disrupted by 30 min scrotal heat treatment at 43°C. Ten sessions of EA were given at Baihui (GV20), Guanyuan (CV4), Zusanli (ST36) and Sanyinjiao (SP6) from day 9 to day 36 post-treatment. Sperm motility and production, morphology of the germinal epithelium by Johnsen’s scoring, germ cell apoptosis by TUNEL staining, proliferation by proliferating cell nuclear antigen (PCNA) staining, as well as serum testosterone and inhibin B levels by immunoassays were evaluated on day 0, 1, 9, 25, 37, 46, 56 and 79. When compared with the heat-treated (H) group, the heat-treated plus EA (H+EA) group showed a significant increase (p < 0.05) in PCNA-positive cells and inhibin B levels on days 37 and 46, and a higher Johnsen’s score till day 56. On day 79, motile spermatozoa could be found in the vas deferens of H+EA group only. Consistently, there was a trend of improved motility and increased number of motile epididymal spermatozoa in the H+EA group than the H group; while apoptosis of germ cells and serum testosterone levels were similar between the two groups. Taken together, EA enhanced germ cell proliferation through improvement of Sertoli cell functions. This may facilitate the recovery of spermatogenesis and may restore normal semen parameters in subfertile patients.

Abstract
BACKGROUND Pethidine with midazolam-induced conscious sedation for pain relief during transvaginal oocyte retrieval for in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) procedures is associated with residual pain and oversedation. Patient-controlled analgesia (PCA) with remifentanil may serve as an alternative for pethidine. We investigated whether PCA remifentanil with diclofenac was associated with improved periprocedural pain relief than pethidine analgesia during IVF/ICSI procedures, with sedation scores, safety profiles, and patient satisfaction as secondary endpoints. METHODS Seventy-six women were randomized to receive pethidine (2 mg/kg i.m.) and midazolam (7.5 mg)-induced conscious sedation (n = 40) or PCA with remifentanil and diclofenac (50 mg; n = 36). The Numeric Rating Scale, McGill Pain Questionnaire (MPQ), Ramsey Sedation Scale, and a 5-day pain-and-discomfort diary were used to evaluate pain and sedation levels. RESULTS There were no differences in baseline characteristics and reproductive outcomes between both groups. Periprocedural pain scores were comparable for remifentanil and pethidine groups (4 [3 to 7] vs. 6 [4 to 8]; P = 0.13). Pain scores in the pethidine group were significantly lower at 30 minutes after the procedure (1 [0 to 3] vs. 2 [1 to 5]; P = 0.016), but at cost of higher sedation levels when compared to remifentanil (4 [2 to 4] vs. 2 [2 to 2]; P < 0.001). Patient satisfaction was higher, and MPQ scores were lower in the remifentanil group. There were no differences in safety profiles between both analgesics. CONCLUSIONS Patient-controlled analgesia with remifentanil showed a similar reduction in pain scores than pethidine with midazolam during oocyte retrieval, while pethidine induced the highest pain relief after the procedure. However, PCA remifentanil was associated with less sedation and a better patient satisfaction profile than pethidine.

Abstract
BACKGROUND Recent systematic reviews of adjuvant acupuncture for IVF have pooled heterogeneous trials, without examining variables that might explain the heterogeneity. The aims of our meta-analysis were to quantify the overall pooled effects of adjuvant acupuncture on IVF clinical pregnancy success rates, and evaluate whether study design-, treatment- and population-related factors influence effect estimates. METHODS We included randomized controlled trials that compared needle acupuncture administered within 1 day of embryo transfer, versus sham acupuncture or no adjuvant treatment. Our primary outcome was clinical pregnancy rates. We obtained from all investigators additional methodological details and outcome data not included in their original publications. We analysed sham-controlled and no adjuvant treatment-controlled trials separately, but since there were no large or significant differences between these two subsets, we pooled all trials for subgroup analyses. We prespecified 11 subgroup variables (5 clinical and 6 methodological) to investigate sources of heterogeneity, using single covariate meta-regressions. RESULTS Sixteen trials (4021 participants) were included in the meta-analyses. There was no statistically significant difference between acupuncture and controls when combining all trials [risk ratio (RR) 1.12, 95% confidence interval (CI), 0.96-1.31; I(2) = 68%; 16 trials; 4021 participants], or when restricting to sham-controlled (RR 1.02, 0.83-1.26; I(2) = 66%; 7 trials; 2044 participants) or no adjuvant treatment-controlled trials (RR 1.22, 0.97-1.52; I(2) = 67%; 9 trials; 1977 participants). The type of control used did not significantly explain the statistical heterogeneity (interaction P = 0.27). Baseline pregnancy rate, measured as the observed rate of clinical pregnancy in the control group of each trial, was a statistically significant effect modifier (interaction P < 0.001), and this covariate explained most of the heterogeneity of the effects of adjuvant acupuncture across all trials (adjusted R(2) = 93%; I(2) residual = 9%). Trials with lower control group rates of clinical pregnancy showed larger effects of adjuvant acupuncture (RR 1.53, 1.28-1.84; 7 trials; 1732 participants) than trials with higher control group rates of clinical pregnancy (RR 0.90, 0.80-1.01; 9 trials; 2289 participants). The asymmetric funnel plot showed a tendency for the intervention effects to be more beneficial in smaller trials. CONCLUSIONS We found no pooled benefit of adjuvant acupuncture for IVF. The subgroup finding of a benefit in trials with lower, but not higher, baseline pregnancy rates (the only statistically significant subgroup finding in our earlier review) has been confirmed in this update, and was not explained by any confounding variables evaluated. However, this baseline pregnancy rate subgroup finding among published trials requires further confirmation and exploration in additional studies because of the multiple subgroup tests conducted, the risk of unidentified confounders, the multiple different factors that determine baseline rates, and the possibility of publication bias.

Abstract
BACKGROUND Various methods of conscious sedation and analgesia have been used for pain relief during oocyte recovery in in vitro fertilisation (IVF) and intra-cytoplasmic sperm injection (ICSI) procedures. The choice of agent has also been influenced by the quality of sedation and analgesia as well as by concerns about possible detrimental effects on reproductive outcomes. OBJECTIVES To assess the effectiveness and safety of different methods of conscious sedation and analgesia on pain relief and pregnancy outcomes in women undergoing transvaginal oocyte retrieval. SEARCH METHODS We searched the Menstrual Disorders and Subfertility Group Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL (from their inception to present); the National Research Register and Current Controlled Trials. We searched reference lists of included studies for relevant studies and contacted authors for information on unpublished and ongoing trials. There was no language restriction. The search was updated in July 2012. SELECTION CRITERIA Only randomised controlled trials comparing different methods of conscious sedation and analgesia for pain relief during oocyte recovery were included. DATA COLLECTION AND ANALYSIS Quality assessment and data extraction were performed independently by two review authors. Interventions were classified and analysed under broad categories or strategies of sedation and pain relief to compare different methods and administrative protocols of conscious sedation and analgesia. Outcomes were extracted and the data were pooled when appropriate. MAIN RESULTS With this update, nine new studies were identified resulting in a total of 21 trials including 2974 women undergoing oocyte retrieval. These trials compared five different categories of conscious sedation and analgesia: 1) conscious sedation and analgesia versus placebo; 2) conscious sedation and analgesia versus other active interventions such as general and acupuncture anaesthesia; 3) conscious sedation and analgesia plus paracervical block versus other active interventions such as general, spinal and acupuncture anaesthesia; 4) patient-controlled conscious sedation and analgesia versus physician-administered conscious sedation and analgesia; and 5) conscious sedation and analgesia with different agents or dosage. Evidence was generally of low quality, mainly due to poor reporting of methods, small sample sizes and inconsistency between the trials.Conflicting results were shown for women's experience of pain. Compared to conscious sedation alone, more effective pain relief was reported when conscious sedation was combined with electro-acupuncture: intra-operative pain mean difference (MD) on 1 to 10 visual analogue scale (VAS) of 3.00 (95% CI 2.23 to 3.77); post-operative pain MD in VAS units of 2.10 (95% CI 1.40 to 2.80; N = 61, one trial, low quality evidence); or paracervical block (MD not calculable).The pooled data of four trials showed a significantly lower intra-operative pain score with conscious sedation plus paracervical block than with electro-acupuncture plus paracervical block (MD on 10-point VAS of -0.66; 95% CI -0.93 to -0.39; N = 781, 4 trials, low quality evidence) with significant statistical heterogeneity (I(2) = 76%). Patient-controlled sedation and analgesia was associated with more intra-operative pain than physician-administered sedation and analgesia (MD on 10-point VAS of 0.60; 95% CI 0.16 to 1.03; N = 379, 4 trials, low quality evidence) with high statistical heterogeneity (I(2) = 83%). Post-operative pain was reported in only nine studies. As different types and dosages of sedative and analgesic agents, as well as administrative protocols and assessment tools, were used in these trials the data should be interpreted with caution.There was no evidence of a significant difference in pregnancy rate in the 12 studies which assessed this outcome, and pooled data of four trials comparing electro-acupuncture combined with paracervical block with conscious sedation and analgesia plus paracervical block showed an odds ratio (OR) of 0.96 (95% CI 0.72 to 1.29; N = 783, 4 trials) for pregnancy. High levels of women's satisfaction were reported for all modalities of conscious sedation and analgesia as assessed in 12 studies. Meta-analysis of all the studies was not attempted due to considerable heterogeneity.For the rest of the trials a descriptive summary of the outcomes was presented. AUTHORS' CONCLUSIONS The evidence from this review of 21 randomised controlled trials did not support one particular method or technique over another in providing effective conscious sedation and analgesia for pain relief during and after oocyte recovery. The simultaneous use of more than one method of sedation and pain relief resulted in better pain relief than one modality alone. The various approaches and techniques reviewed appeared to be acceptable and were associated with a high degree of satisfaction in women. As women vary in their experience of pain and in coping strategies, the optimal method may be individualised depending on the preferences of both the women and the clinicians and resource availability.

Abstract
Acupuncture is often recommended for obstetrical and gynecological conditions but the evidence is confusing. We aim to summarize all recent systematic reviews in this area. Western and Asian electronic databases were searched for systematic reviews of any type of acupuncture for any type of gynecological conditions. Our own files were hand-searched. Systematic reviews of any type of acupuncture for any type of gynecological conditions were included. Non-systematic reviews and systematic reviews published before 2004 were excluded. No language restrictions were applied. Data were extracted according to predefined criteria and analysed narratively. Twenty-four systematic reviews were included. They relate to a wide range of gynecological conditions: hot flashes, conception, dysmenorrhea, premenstrual syndrome, nausea/vomiting, breech presentation, back pain during pregnancy, and procedural pain. Nine systematic reviews arrived with clearly positive conclusions; however, there were many contradictions and caveats. The evidence for acupuncture as a treatment of obstetrical and gynecological conditions remains limited.

Abstract
Acupuncture is commonly used for pain control, but doubts about its effectiveness and safety remain. This review was aimed at critically evaluating systematic reviews of acupuncture as a treatment of pain and at summarizing reports of serious adverse effects published since 2000. Literature searches were carried out in 11 databases without language restrictions. Systematic reviews were considered for the evaluation of effectiveness and case series or case reports for summarizing adverse events. Data were extracted according to predefined criteria. Fifty-seven systematic reviews met the inclusion criteria. Four were of excellent methodological quality. Numerous contradictions and caveats emerged. Unanimously positive conclusions from more than one high-quality systematic review existed only for neck pain. Ninety-five cases of severe adverse effects including 5 fatalities were included. Pneumothorax and infections were the most frequently reported adverse effects. In conclusion, numerous systematic reviews have generated little truly convincing evidence that acupuncture is effective in reducing pain. Serious adverse effects continue to be reported. Numerous reviews have produced little convincing evidence that acupuncture is effective in reducing pain. Serious adverse events, including deaths, continue to be reported.

Abstract
BACKGROUND Acupuncture has been used as treatment for infertility for hundreds of years, and recently it has been studied in male and female infertility and in assisted reproductive technologies, although its role in reproductive medicine is still debated. AIM To review studies on acupuncture in reproductive medicine, in experimental and clinical settings. METHODS Papers were retrieved on PubMed and Google Scholar and were included in the review if at least the abstract was in English. RESULTS There is evidence of benefit mainly when acupuncture is performed on the day of embryo transfer (ET) in the live birth rate. Benefit is also evident when acupuncture is performed for female infertility due to polycystic ovary syndrome (PCOS). There is some evidence of sperm quality improvement when acupuncture is performed on males affected by idiopathic infertility. Experimental studies suggest that acupuncture effects are mediated by changes in activity of the autonomic nervous system and stimulation of neuropeptides/neurotransmitters which may be involved in the pathogenesis of infertility. CONCLUSIONS Acupuncture seems to have beneficial effects on live birth rate when performed on the day of ET, and to be useful also in PCOS as well as in male idiopathic infertility, with very low incidence of side effects. However, further studies are necessary to confirm the clinical results and to expand our knowledge of the mechanisms involved.

Abstract
Acupuncture is increasingly being used in reproductive medicine. This review summarizes the evidence of acupuncture in pain relief for oocyte retrieval, improving pregnancy outcomes of in vitro fertilization treatment, management of ovulation disorders, male subfertility, primary dysmenorrhea, endometriosis and menopausal symptoms. However, most of the studies are nonrandomized uncontrolled trials, case reports or case series. For randomized controlled trials, the sample size is underpowered and blinding of assessors is lacking. Different acupuncture protocols and controls are used. These heterogeneities make it difficult to compare studies and draw any firm conclusions. Further studies should also evaluate the cost-effectiveness of acupuncture and investigate the underlying mechanism of acupuncture treatment.

Abstract
OBJECTIVE A possible negative effect of pain-relieving analgesics used during oocyte retrieval on fertilization and embryo development has been discussed. This study examines whether alfentanil dosage adversely affects fertilization and/or embryo quality. STUDY DESIGN In a retrospective observational study the effect of different doses of alfentanil on two primary endpoints, fertilization rate and good quality embryo (GQE) rate, were compared in 663 women. RESULTS In group A (<or=0.5mg alfentanil) and group B (>0.5mg alfentanil) mean fertilization rate was 0.6+/-0.3 versus 0.6+/-0.2 (P=0.678, adjusted P=0.937, 95% CI for the difference -0.041; 0.044) and mean GQE rate was 0.6+/-0.3 versus 0.5+/-0.3 (P=0.207, adjusted P=0.179, 95% CI for the difference -0.015; 0.078), respectively. A paired comparison of 65 women who underwent repeated IVF cycles found that, compared with <or=0.5mg alfentanil, doses of >0.5mg alfentanil had no adverse effects on fertilization rate (mean difference 0.05+/-0.3, P=0.231, 95% CI -0.02; 0.12) or GQE rate (mean difference -0.02+/-0.4, P=0.970, 95% CI -0.12; 0.09). CONCLUSION The amount of alfentanil is not associated with adverse effects on fertilization rate, embryo development, or clinical pregnancy rate, which is reassuring and indicates that women can be offered adequate pain relief.

Abstract
The prevalence of atopic diseases and diabetes is increasing worldwide, though the co-occurrence of both diseases in the same individual is less frequent than predicted. Previously published studies suggest that the Th1/Th2 concept could explain the inverse relationship between allergic diseases and type 1 diabetes. However, down-regulation of the IgE-mast cell system can also markedly contribute to the lack of responsiveness to local and systemic allergen challenges in diabetic conditions. Moreover, dysregulation of the hypothalamic-pituitary-adrenocortical axis and elevated endogenous glucocorticoid levels play a pertinent role in some of the pathological-related processes associated with poorly controlled or uncontrolled diabetes.

Abstract
OBJECTIVE To review systematically the use of acupuncture in the management of subfertility. DESIGN A computer search was performed via several English and Chinese databases to identify journals relevant to the subject. RESULT(S) The positive effect of acupuncture in the treatment of subfertility may be related to the central sympathetic inhibition by the endorphin system, the change in uterine blood flow and motility, and stress reduction. Acupuncture may help restore ovulation in patients with polycystic ovary syndrome, although there are not enough randomized studies to validate this. There is also no sufficient evidence supporting the role of acupuncture in male subfertility, as most of the studies are uncontrolled case reports or case series in which the sample sizes were small. Despite these deficiencies, acupuncture can be considered as an effective alternative for pain relief during oocyte retrieval in patients who cannot tolerate side effects of conscious sedation. The pregnancy rate of IVF treatment is significantly increased, especially when acupuncture is administered on the day of embryo transfer. CONCLUSION(S) Although acupuncture has gained increasing popularity in the management of subfertility, its effectiveness has remained controversial.

Abstract
The aim of this observational two-centre study was to investigate different aspects of pain in oocyte aspiration in conjunction with IVF, whether the preoperative information to women was sufficient, and which factor(s) influenced a woman's sense of security. The study group comprised 124 women who underwent IVF treatment. The visual analogue scale (VAS) was used to measure pain, and multiple-choice questions were used to evaluate satisfaction and sense of security. The women rated expected pain significantly higher than mean pain during surgery (P < 0.0001). They would have accepted significantly more pain than they experienced (P < 0.0001). In a stepwise linear regression analysis, total dose of alfentanil was the only variable that was independently associated with mean pain. Satisfaction with the preoperative information was high. Women considered staff competence to be important for their sense of security. In conclusion, women rated oocyte aspiration to be less painful than they expected before surgery. This is important information for women who are about to start IVF treatment, since it might reduce apprehension about the level of pain that could be expected during oocyte aspiration.

Abstract
Electro-acupuncture has previously proven its analgesic effect in oocyte retrieval for IVF. The aim of the present prospective randomized study was to explore the optimal frequency for analgesia when electro-acupuncture was applied a few minutes prior to oocyte retrieval. A total of 152 patients were prospectively randomized to receive either a combination of high (80 Hz) and low frequency (2 Hz), 3 s each, a so-called mixed frequency, or a fixed frequency of 20 Hz during oocyte retrieval. In addition to electro-acupuncture, both groups had a paracervical block and manual acupuncture. No differences in pain before, during or after oocyte retrieval between the two groups were seen. In the fixed frequency group, however, a higher level of anxiety (P < 0.05) before oocyte retrieval was seen, and a higher level of nausea after aspiration of one ovary (P < 0.01) was seen in the mixed frequency group. No differences were seen regarding clinical outcome parameters. Contrary to previous reports on acute and chronic pain, the analgesic effect of the mixed frequency and the fixed frequency was similar when used for short duration electro-acupuncture.

Abstract
BACKGROUND A pre-ovarian block (POB) technique can be used for pain relief during oocyte retrieval in IVF. The local anaesthetic is deposited in the vaginal wall and between the vaginal wall and the peritoneal surface near the ovary using ultrasound guidance. The aim of this study was to test whether analgesia with POB resulted in improved pain relief compared to paracervical block (PCB). METHODS A prospective, randomized, multicentre study of POB versus PCB (10 ml of 1% lidocaine each) with 183 patients randomized to POB (n = 96) or PCB (n = 87) was performed. Randomization (via a computer-generated list) was balanced for age, previously completed IVF cycles, degree of anxiety, estimated number of follicles, BMI, premedication and centre. Pain was measured using a visual analogue scale (VAS, 0-100 mm) and given as median values. The primary end-point of this study was overall VAS pain score for both sides during the oocyte retrieval procedure. RESULTS Overall pain during the entire oocyte retrieval was 22 (POB) and 16 (PCB) (P = 0.42). No differences were found in degree of anxiety, premedication, dose of alfentanil, fertilization rate, number of good-quality embryos or clinical pregnancy rate. CONCLUSIONS No differences were found in overall pain experienced during the entire oocyte retrieval procedure with POB compared to PCB.

Abstract
BACKGROUND Various methods of sedation and analgesia have been used for pain relief during oocyte recovery during IVF. OBJECTIVE To compare conscious sedation and analgesia with alternative methods for pain relief and pregnancy outcomes. METHODS We searched the Specialised Register of the Menstrual Disorders and Subfertility Group, the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, the National Research Register and Current Controlled Trials up to February 2004. RESULTS Twelve trials were included. Owing to considerable heterogeneity, regarding types and dosages of sedation or analgesia used, and tools used to assess pain, a meta-analysis was attempted only in trials where appropriate data were available. Clinical pregnancy rates per woman in individual trials were comparable. Data on pain showed conflicting results. CONCLUSION No single method or delivery system appeared superior for pregnancy rates and pain relief. Future studies need to be consistent in the choice of tools used to measure pain and the timing of such evaluations.

Abstract
BACKGROUND The aim of this study was to compare the pain-relieving effect and the subjective well-being between auricular electro-acupuncture (EA) analgesia, auricular acupuncture (A) and conventional analgesia with remifentanil (CO). METHODS A total of 94 women undergoing IVF were randomized to auricular acupuncture with (EA, n = 32) or without (A, n = 32) continuous 1 Hz auricular stimulation (using a battery-powered miniaturized stimulator, P-Stim) or with adhesive tapes instead of needles and no electrical stimulation (control group, CO, n = 30) at the auricular acupuncture points 29, 55 and 57. All patients received patient-controlled analgesia (PCA) with remifentanil. Pain intensity and psychological well-being were assessed by means of visual analogue scales (VAS); tiredness, nausea and vomiting and analgesic drug consumption were documented. RESULTS Pain relief and subjective well-being were significantly greater in group EA during and after the procedure as compared with groups A and CO (P < 0.001). The patients were significantly more tired in group CO than in groups A and EA (P < 0.001). Consumption of the opioid remifentanil was significantly lower in group EA, comparable nausea (P < 0.001). CONCLUSION Auricular EA significantly reduces pain intensity and analgesic consumption of the opioid remifentanil during oocyte aspiration in IVF treatment.

Abstract
Even though widely used in today's clinical practice, acupuncture has remained a controversial subject. Many reviews are currently available but most lack a critical stance and some are overtly promotional. The aim of this overview is to provide a balanced, critical analysis of the existing evidence. Some of the original concepts of traditional acupuncture are not supported by good scientific evidence. Several plausible theories attempt to explain how acupuncture works but none are proved beyond doubt. The clinical effectiveness of acupuncture continues to attract controversy. Many controlled clinical trials and numerous systematic reviews of these studies have been published. Considerable problems are encountered when interpreting these data. Heterogeneity is a significant drawback of both clinical trials and systematic reviews. Some of the controversies may be resolved through the use of the new 'placebo needles' which enable researchers to adequately control for placebo effects of acupuncture. The majority of studies using such devices fails to show effects beyond a placebo response. Acupuncture has been associated with serious adverse events but most large-scale studies suggest that these are probably rare. Nonserious adverse effects occur in 7-11% of all patients. In conclusion, acupuncture remains steeped in controversy. Some findings are encouraging but others suggest that its clinical effects mainly depend on a placebo response.

Abstract
BACKGROUND Various methods of sedation and analgesia have been used for pain relief during oocyte recovery in IVF/ICSI procedures. The choice of agents has also been influenced by quality of analgesia as well as by concern about possible detrimental effects on reproductive outcome. OBJECTIVES To assess the efficacy of conscious sedation and analgesia versus alternative methods on pregnancy outcomes and pain relief in patients undergoing transvaginal oocyte retrieval. SEARCH STRATEGY We searched the Specialised Register of the Menstrual Disorders and Subfertility Group, The Central Register of Controlled Trials (CENTRAL) , MEDLINE (1966 to present), EMBASE (1980 to present), CINAHL (1982 to present), the National Research Register, and Current Controlled Trials. There was no language restriction. All references in the identified trials and background papers were checked and authors contacted to identify relevant published and unpublished data. SELECTION CRITERIA Only randomised controlled trials comparing conscious sedation and analgesia versus alternative methods for pain relief during oocyte recovery were included. DATA COLLECTION AND ANALYSIS Two reviewers independently scanned abstracts of the reports identified by electronic searching to identify relevant papers, extracted data and assessed trial quality. Interventions were classified and analysed under broad categories/strategies of pain relief comparing conscious sedation/analgesia with alternative methods and administration protocols. MAIN RESULTS Our search strategy identified 390 potentially eligible reports and 12 papers met our inclusion criteria. There were no significant differences in clinical pregnancy rates per woman and patient satisfaction between the methods compared. Women's perception of pain showed conflicting results. Due to considerable heterogeneity, in terms of types and dosages of sedation or analgesia used, and tools used to assess the principal outcomes of pain and satisfaction, a meta-analysis of all the studies was not attempted. Of the three trials which compared the effect of conventional medical analgesia plus paracervical block versus electro-acupuncture plus paracervical block, there was no significant difference in clinical pregnancy rates per woman in the two groups (OR 1.01; 95% CI 0.73 to 1.4). For intra-operative pain score as measured by visual analogue scale (VAS), there was a significant difference (WMD -4.95; 95% CI -7.84 to -2.07), favouring conventional medical analgesia plus paracervical block . There was also a significant difference in intra-operative pain by VAS between patient-controlled sedation and physician-administered sedation (WMD 5.98; 95% CI 1.63 to 10.33), favouring physician -administered sedation. However, as different types and dosages of sedative and analgesic agents were used in these trials, these data should be interpreted with caution. For the rest of the trials, a descriptive summary of the outcomes was presented. AUTHORS' CONCLUSIONS There is insufficient evidence to determine the effect of different methods of pain relief when compared with conscious sedation and analgesia used during oocyte recovery. In this review, no one particular pain relief method or delivery system appeared to be better than the other. In future, greater consensus is needed to determine both the tools used to evaluate pain and the timing of pain evaluation during and after the procedure. Pain assessment using both subjective and objective measures may merit consideration. In addition, future trials should include intra- and post-operative adverse respiratory and cardiovascular events as outcomes.
