Backgound Endometriosis is a common chronic gynecological condition characterized by the presence of endometrial tissue outside the uterine cavity, leading to chronic inflammation, pelvic nodules and masses, pelvic pain, and infertility. Acupuncture has been shown to improve pain associated with endometriosis by modulating abnormal levels of prostaglandins, β-endorphins, dynorphins, electrolytes, and substance P. This review aims to evaluate the clinical efficacy of acupuncture in treating endometriosis, specifically focusing on its efficacy in relieving pain associated with endometriosis.
Methods A comprehensive search was conducted in eight databases (PubMed, EMBASE, Cochrane, Web of Science, China National Knowledge Infrastructure (CNKI), the China Biology Medicine (CBM), Wanfang, and Weipu database) to identify randomized controlled trials (RCTs) published from database inception to December 16, 2022, which investigated the use of acupuncture for endometriosis-related pain. Two researchers independently screened articles, extracted data, and assessed methodological quality using the Cochrane Collaboration's risk of bias tool. Meta-analysis was performed using Stata statistical software.
Results A total of 1991 articles were identified, and ultimately, 14 studies involving 793 patients (387 in the acupuncture group and 359 in the control group) were included. The control interventions in the included studies included placebo, traditional Chinese medicine (TCM), and Western medicine treatments. Meta-analysis results showed that compared to the control group, acupuncture treatment for pain associated with endometriosis demonstrated significant reductions in pain severity [SMD = - 1.10, 95% CI (- 1.45, - 0.75), P < 0.001], improved response rate [RR = 1.25, 95% CI (1.09, 1.44), P = 0.02], and decreased serum CA-125 levels [SMD = - 0.62, 95% CI (- 1.15, - 0.08), P = 0.024]. Furthermore, subgroup analysis revealed that electroacupuncture and auricular acupuncture were superior to the control group in reducing pain severity, while auricular acupuncture and warm needling showed greater clinical efficacy compared to the control group. However, there were no significant differences between electroacupuncture or fire needling and the control group in terms of pain relief. The findings suggest that acupuncture is effective in improving pain associated with endometriosis.
Conclusions In conclusion, acupuncture is effective in alleviating dysmenorrhea and pelvic pain associated with endometriosis, reducing serum CA-125 levels, decreasing the size of nodules, improving patients' quality of life, and lowering the recurrence rate. However, it should be noted that the current evidence is limited by the design and quality flaws of the original studies, as well as a lack of research specifically focusing on subtypes of acupuncture. Therefore, caution should be exercised when interpreting the results.

Background Current endometriosis treatments do not always provide symptom relief, with many using complementary approaches. This study examined the effectiveness of acupuncture on pain and quality of life in people with endometriosis.
Methods Searches were conducted on Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Allied and Complementary Medicine Database (AMED) and Embase (Ovid), Epistemonikos, and Cumulative Index to Nursing and Allied Health Literature (CINAHL; EBSCOhost) on 20 March 2023. Trials were included if they used penetrating acupuncture. Risk of bias was assessed with Cochrane RoB2 and GRADE for overall evidence certainty. Random-effects meta-analyses were undertaken, using Hedges' g or mean difference (MD) both with 95 % confidence intervals (CI).
Results Six studies involving a total of 331 participants were included. Evidence for benefit was found for acupuncture compared to non-specific acupuncture on overall pelvic pain (g = 1.54, 95 % CI 0.92 to 2.16, 3 RCTs, n = 231, low certainty evidence, p<0.001), menstrual pain (g = 1.67, 95 % CI 1.23 to 2.12, 1 RCT, n = 106, moderate certainty evidence, p<0.001), and non-specified pelvic pain (MD -2.77, 95 % CI 2.15 to 3.38, 2 RCTs, n = 125, low certainty evidence, p<0.001), and compared to usual care on menstrual pain (g = 0.9, 95 % CI 0.15 to 1.64, 1 RCT, n = 19, very low certainty evidence, p = 0.02). Most studies reported low rates of adverse events.
Conclusion Acupuncture treatment for endometriosis demonstrated clinically relevant improvements in pelvic pain and should be considered as a potential treatment intervention.

ObjectivesThis study aimed to examine the effect of acupuncture on symptoms and health-related quality of life in patients with endometriosis.
MethodsNine biomedical databases were searched to April 2022 to identify randomized controlled trials of acupuncture and/or moxibustion used alone or as adjunct to guideline-recommended pharmacotherapy for the treatment of endometriosis. One reviewer extracted data and another verified the data. A random effects model was used to calculate mean differences.
Results Fifteen trials involving 1018 patients met the inclusion criteria, but diversity in comparisons and outcome measures prevented meta-analysis. Compared to sham acupuncture, manual acupuncture was more effective at reducing dysmenorrhea VAS pain score (mean difference [MD] - 2.40, 95 % CI [- 2.80, - 2.00]; moderate certainty evidence), pelvic pain VAS score (MD - 2.65, 95 % CI [- 3.40, - 1.90]; high certainty evidence) and dyspareunia VAS scores (MD - 2.88, [- 3.83, - 1.93]), lessened the size of ovarian cyst (MD - 3.88, 95 % CI [- 7.06, - 0.70]), and improved quality of life. Compared to conventional therapy, manual acupuncture plus conventional therapy and warm needle alone resulted in greater improvements in quality of life than conventional therapy. Among the six studies that reported safety, fewer adverse events were reported in participants who received acupuncture or moxibustion.
Conclusions Low to moderate certainty evidence from single studies showed that manual acupuncture may improve pain-related symptoms and quality of life; however, there is insufficient evidence on the overall effectiveness of acupuncture and moxibustion for endometriosis

Background Despite advances in treatments for endometriosis, some symptoms persist owing to the chronic inflammation observed in this disease.
Objective To identify resources, methods, and/or complementary treatments to alleviate the pain symptoms of endometriosis, and to identify adverse effects of treatments.
MethodsSEARCH STRATEGY: Lilacs, Scielo, PEDro, Scopus, Pubmed, CENTRAL Cochrane, Science Direct, and Google Scholar were searched for studies published in Portuguese, English, and Spanish to July 31, 2017, using the terms “physical therapy” OR “complementary treatment” AND “endometriosis”. SELECTION CRITERIA: Randomized controlled trials relating to complementary pelvic pain treatment and adverse effects. DATA COLLECTION AND ANALYSIS: Eight studies were identified; two studies were included in the meta-analysis.
Main Results The complementary interventions studied were acupuncture, exercise, electrotherapy, and yoga. All were inconclusive in affirming benefit but demonstrated a positive trend in the treatment of symptoms of endometriosis. Meta-analysis of acupuncture showed a significant benefit in pain reduction as compared with placebo (P=0.007).
ConclusionsNumerous complementary treatments have been used to alleviate the symptoms of endometriosis, but only acupuncture has demonstrated a significant improvement in outcomes. Nevertheless, other approaches demonstrated positive trends toward improving symptoms; this should encourage investigators to design controlled studies to support their applicability.

Xu Y, Zhao W, Li T, Zhao Y, Bu H, Song S. Effects of acupuncture for the treatment of endometriosis-related pain: A systematic review and meta-analysis. PLoS One. 2017;12(10):. [176386].

BackgroundEndometriosis is a multifactorial, oestrogen-dependent, inflammatory, gynaecological condition that can result in long-lasting visceral pelvic pain and infertility. Acupuncture could be an effective treatment for endometriosis and may relieve pain. Our aim in the present study was to determine the effectiveness of acupuncture as a treatment for endometriosis-related pain.
Methods In December 2016, six databases were searched for randomised controlled trials that determined the effectiveness of acupuncture in the treatment of endometriosis-related pain. Ultimately, 10 studies involving 589 patients were included. The main outcomes assessed were variation in pain level, variation in peripheral blood CA-125 level, and clinical effective rate. All analyses were performed using comprehensive meta-analysis statistical software.
Results Of the 10 studies included, only one pilot study used a placebo control and assessed blinding; the rest used various controls (medications and herbs), which were impossible to blind. The sample sizes were small in all studies, ranging from 8 to 36 patients per arm. The mean difference (MD) in pain reduction (pre- minus post-interventional pain level-measured on a 0-10-point scale) between the acupuncture and control groups was 1.36 (95% confidence intervals [CI] = 1.01-1.72, P<0.0001). Acupuncture had a positive effect on peripheral blood CA-125 levels, as compared with the control groups (MD = 5.9, 95% CI = 1.56-10.25, P = 0.008). Similarly, the effect of acupuncture on clinical effective rate was positive, as compared with the control groups (odds ratio = 2.07; 95% CI = 1.24-3.44, P = 0.005).
Conclusions Few randomised, blinded clinical trials have addressed the efficacy of acupuncture in treating endometriosis-related pain. Nonetheless, the current literature suggests that acupuncture reduces pain and serum CA-125 levels, regardless of the control intervention used. To confirm these findings, additional, blinded studies with proper controls and adequate sample sizes are needed.

BackgroundEndometriosis is a multifactorial, estrogen-dependent, inflammatory gynecological condition - often with long-lasting visceral pelvic pain of different origin, and infertility among women. Current management options for patients' are often inadequate, with side effects for many for whom acupuncture techniques could be an alternative. Earlier studies have discussed the efficacy of acupuncture, but not its methodological aspects.
Objectives To summarize the documented clinical effects of acupuncture on rated visceral pelvic endometriosis-related pain, and associated variables among individuals, within and between studied groups, and to discuss the methodological treatment aspects.
Methods Published full text clinical studies, case reports, and observational studies with abstracts written in English were searched by using the keywords “Acupuncture and Endometriosis” in databases such as PubMed, Web of Science, and CINAHL. The reporting guidelines, Standards for Reporting Interventions in Clinical Trials of Acupuncture was used for the methodological report.
Main results Three studies were found including 99 women, 13-40 years old, with diagnosed endometriosis. The studies were different in research design, needle stimulation techniques, and evaluation instruments. Methodological similarities were seven to12 needle insertions per subject/session, and 15-25 minutes of needle retention time. The needles were placed in lower back/pelvic-abdominal area, in the shank, feet, and hands. Treatment numbers varied from nine to 16 and patients received one to two treatments per week. Similarity in reported treatment effects in the quoted studies, irrespective of research design or treatment technique, was reported decrease of rated pain intensity.
Discussion Meta-analysis is the standard procedure for the evaluation of evidence of treatment effects, ie, on a group level, usually without analysis of the individual responses even with obvious spread in the results leading to lack of guidance for treatment of the individual patient. By conceptualizing pain as subjective, the individual aspect should serve as the basis for the analysis to allow clinical recommendations. From a physiological and a western medical perspective, acupuncture can be regarded as a type of sensory stimulation that induces changes in the function of the central nervous system that partly can explain the decrease of perceived pain in response to acupuncture treatment irrespective of the technique.
Authors' conclusionsEndometriosis is often painful, although with various origin, where standard treatments may be insufficient or involve side effects. Based on the reported studies, acupuncture could be tried as a complement as it is an overall safe treatment. In the future, studies designed for evaluating effectiveness between treatment strategies rather than efficacy design would be preferred as the analyses of treatment effects in the individual patients.

Rocha ALL, Reis FM, Petraglia F. New trends for the medical treatment of endometriosis. Expert Opin Investig Drugs 2012;21(7):905-919. [157188].

INTRODUCTION: Endometriosis is a benign sex hormone-dependent gynecological disease, characterized by the presence and growth of endometrial tissue outside the uterus; it affects 10% of women of reproductive age and is associated with infertility and pain. Treatment of endometriosis involves conservative or radical surgery, or medical therapies. The goals for endometriosis treatment may be the relief of pain and/or a successful pregnancy achievement in infertile patients. Treatment must be individualized with a multidisciplinary approach. The classical treatments carry adverse side effects and in some cases a negative impact on quality of life. New agents promise a distinct perspective in endometriosis treatment. AREAS COVERED: The aim of this paper is to systematically review the literature evidence of new medical treatments for endometriosis, defined as pharmacological treatments not yet commonly available and currently under investigation. EXPERT OPINION: These new medical therapies would be used associated with surgical treatment and, in the future, will render possible the association of hormone therapy with non-hormonal treatment for endometriosis. [Several studies have demonstrated the positive effect of acupuncture in the relief of pelvic pain and treatment of infertility. Limited evidence from RCTs suggests that acupuncture is effective in treating dysmenorrhea].

BackgroundEndometriosis is a prevalent gynaecological condition, significantly affecting women's lives. Clinical presentations may vary from absence of symptoms to complaints of chronic pelvic pain, most notably dysmenorrhoea. The management of pain in endometriosis is currently inadequate. Acupuncture has been studied in gynaecological disorders but its effectiveness for pain in endometriosis is uncertain.
Objectives To determine the effectiveness and safety of acupuncture for pain in endometriosis.
Methods Search strategy: We searched the Cochrane Menstrual Disorders and Subfertility Group (MSDG) Specialised Register of controlled trials, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, CINAHL, AMED, PsycINFO, CNKI and TCMDS (from inception to 2010) and reference lists of retrieved articles. Selection criteria: Randomised single or double-blind controlled trials enrolling women of reproductive age with a laparoscopically confirmed diagnosis of endometriosis and comparing acupuncture (body, scalp or auricular) to either placebo or sham, no treatment, conventional therapies or Chinese herbal medicine. Data collection and analysis: Three authors independently assessed risk of bias and extracted data; we contacted study authors for additional information. Meta-analyses were not performed as only one study was included. The primary outcome measure was decrease in pain from endometriosis. Secondary outcome measures included improvement in quality of life scores, pregnancy rate, adverse effects and rate of endometriosis recurrence.
Main results Twenty-four studies were identified that involved acupuncture for endometriosis; however only one trial, enrolling 67 participants, met all the inclusion criteria. The single included trial defined pain scores and cure rates according to the Guideline for Clinical Research on New Chinese Medicine. Dysmenorrhoea scores were lower in the acupuncture group (mean difference -4.81 points, 95% confidence interval -6.25 to -3.37, P < 0.00001) using the 15-point Guideline for Clinical Research on New Chinese Medicine for Treatment of Pelvic Endometriosis scale. The total effective rate ('cured', 'significantly effective' or 'effective') for auricular acupuncture and Chinese herbal medicine was 91.9% and 60%, respectively (risk ratio 3.04, 95% confidence interval 1.65 to 5.62, P = 0.0004). The improvement rate did not differ significantly between auricular acupuncture and Chinese herbal medicine for cases of mild to moderate dysmenorrhoea, whereas auricular acupuncture did significantly reduce pain in cases of severe dysmenorrhoea. Data were not available for secondary outcomes measures.
Authors' conclusionsThe evidence to support the effectiveness of acupuncture for pain in endometriosis is limited, based on the results of only a single study that was included in this review. This review highlights the necessity for developing future studies that are well-designed, double-blinded, randomised controlled trials that assess various types of acupuncture in comparison to conventional therapies.

Experts recommend that clinicians discuss non-medical strategies, such as acupuncture, physiotherapy, electrotherapy, psychological interventions, dietary interventions, and Chinese medicine, to address the quality of life and psychological well-being of women with endometriotic symptoms. However, clinicians should acknowledge that no recommendations can be made for any specific non-medical intervention to reduce pain or improve quality-of-life measures in women with endometriosis, since the potential benefits and harms are unclear (grade D)

Treatment of endometriosis-associated pain. Non-medical management strategies. The GDG recommends that clinicians discuss non-medical strategies to address quality of life and psychological well-being in women managing symptoms of endometriosis. However, no recommendations can be made for any specific non-medical intervention (Chinese medicine, nutrition, electrotherapy, acupuncture, physiotherapy, exercise, and psychological interventions) to reduce pain or improve quality of life measures in women with endometriosis, as the potential benefits and harms are unclear.
Non-medical management strategies for infertility. Regarding non-medical strategies on infertility, there is no clear evidence that any non-medical interventions for women with endometriosis will be of benefit to increase the chance of pregnancy. No recommendation can be made to support any non-medical interventions (nutrition, Chinese medicine, electrotherapy, acupuncture, physiotherapy, exercise, and psychological interventions) to increase fertility in women with endometriosis. The potential benefits and harms are unclear.

Owing to the lack of controlled, randomized studies to date on complementary and integrative approaches to the treatment of endometriosis, no recommendations can be made. Women with chronic recurrent endometriosis and corresponding symptoms may obtain relief of symptoms and an improvement in quality of life from the use of complementary therapies . In particular, these include the methods of acupuncture and Chinese medicine, classical homeopathy, herbal medicine, physiotherapy, etc. This should always be preceded by appropriate clinical screening for potential organ changes (endometriomas, hydronephrosis). Although results from larger scale, randomized and controlled studies are not yet available, initial investigations clearly point to acupuncture and Chinese herbal medicine having an effect on endometriosis-induced pain.

Recommendation The GDG does not recommend the use of nutritional supplements, complementary or alternative medicine in the treatment of endometriosis-associated pain, because the potential benefits and/or harms are unclear. However, the GDG acknowledges that some women who seek complementary and alternative medicine may feel benefit from this.

Acupuncture and CHM may have roles to play in the treatment of CPP associated with dysmenorrhoea, endometriosis, IBS and PID, either as an adjunct or as an alternative to conventional treatments. Unfortunately the current evidence lacks rigour and the available trials are frequently small, poorly designed, and inadequately reported. As a consequence we can only consider this preliminary evidence. This area clearly requires further more rigorous investigation
