Meta-Analysis
Given the increase in the incidence of breast cancer during the past decades, several studies have investigated the effects of variables on breast cancer, especially obesity. This systematic review and meta-analysis aims to evaluate any effects of obesity on breast cancer risk in women, before and after menopause, and in different continents.All forms of relevant literature examining any association between obesity and breast cancer, including cohort, case-control, and cross-sectional studies, were identified in the PubMed, Scopus, EMBASE, and Web of Science databases from January 1, 1990 until January 13, 2023. Body mass index (BMI) > 30 was used to indicate obesity. Every type of breast cancer was examined as outcome factors. The quality of the papers was evaluated using the Newcastle-Ottawa scale checklist. The Egger and Begg test was used to evaluate publication bias. To assess any extra impact of each research on the final measurement, a sensitivity analysis was carried out.One hundred and two studies were included in this meta-analysis. Respectively, 48 and 67 studies reported associations between obesity and breast cancer in pre and post menopausal women. Combining all studies, the pooled OR of the association between obesity and breast cancer in pre-menopausal women was OR = 0.93 CI: (0.85-1.1), (I = 65.4%), and for post-menopausal woman, OR = 1.26 CI: (1.19-1.34), (I = 90.5%).Obesity has a protective role in breast cancer among pre-menopausal women, but this relationship is statistically significant only in European women. The chance of developing breast cancer increases in post-menopausal women who are obese. This relationship is significant among Asian, North American, African and European women.

Meta-Analysis Review
BACKGROUND
Emergency contraception (EC) is using a drug or copper intrauterine device (Cu-IUD) to prevent pregnancy shortly after unprotected intercourse. Several interventions are available for EC. Information on the comparative effectiveness, safety and convenience of these methods is crucial for reproductive healthcare providers and the women they serve. This is an update of a review previously published in 2009 and 2012.
OBJECTIVES
To determine which EC method following unprotected intercourse is the most effective, safe and convenient to prevent pregnancy.
SEARCH METHODS
In February 2017 we searched CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, Popline and PubMed, The Chinese biomedical databases and UNDP/UNFPA/WHO/World Bank Special Programme on Human Reproduction (HRP) emergency contraception database. We also searched ICTRP and ClinicalTrials.gov as well as contacting content experts and pharmaceutical companies, and searching reference lists of appropriate papers.
SELECTION CRITERIA
Randomised controlled trials including women attending services for EC following a single act of unprotected intercourse were eligible.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures recommended by Cochrane. The primary review outcome was observed number of pregnancies. Side effects and changes of menses were secondary outcomes.
MAIN RESULTS
We included 115 trials with 60,479 women in this review. The quality of the evidence for the primary outcome ranged from moderate to high, and for other outcomes ranged from very low to high. The main limitations were risk of bias (associated with poor reporting of methods), imprecision and inconsistency. Comparative effectiveness of different emergency contraceptive pills (ECP)Levonorgestrel was associated with fewer pregnancies than Yuzpe (estradiol-levonorgestrel combination) (RR 0.57, 95% CI 0.39 to 0.84, 6 RCTs, n = 4750, I = 23%, high-quality evidence). This suggests that if the chance of pregnancy using Yuzpe is assumed to be 29 women per 1000, the chance of pregnancy using levonorgestrel would be between 11 and 24 women per 1000.Mifepristone (all doses) was associated with fewer pregnancies than Yuzpe (RR 0.14, 95% CI 0.05 to 0.41, 3 RCTs, n = 2144, I = 0%, high-quality evidence). This suggests that if the chance of pregnancy following Yuzpe is assumed to be 25 women per 1000 women, the chance following mifepristone would be between 1 and 10 women per 1000.Both low-dose mifepristone (less than 25 mg) and mid-dose mifepristone (25 mg to 50 mg) were probably associated with fewer pregnancies than levonorgestrel (RR 0.72, 95% CI 0.52 to 0.99, 14 RCTs, n = 8752, I = 0%, high-quality evidence; RR 0.61, 95% CI 0.45 to 0.83, 27 RCTs, n = 6052, I = 0%, moderate-quality evidence; respectively). This suggests that if the chance of pregnancy following levonorgestrel is assumed to be 20 women per 1000, the chance of pregnancy following low-dose mifepristone would be between 10 and 20 women per 1000; and that if the chance of pregnancy following levonorgestrel is assumed to be 35 women per 1000, the chance of pregnancy following mid-dose mifepristone would be between 16 and 29 women per 1000.Ulipristal acetate (UPA) was associated with fewer pregnancies than levonorgestrel (RR 0.59; 95% CI 0.35 to 0.99, 2 RCTs, n = 3448, I = 0%, high-quality evidence). Comparative effectiveness of different ECP dosesIt was unclear whether there was any difference in pregnancy rate between single-dose levonorgestrel (1.5 mg) and the standard two-dose regimen (0.75 mg 12 hours apart) (RR 0.84, 95% CI 0.53 to 1.33, 3 RCTs, n = 6653, I = 0%, moderate-quality evidence).Mid-dose mifepristone was associated with fewer pregnancies than low-dose mifepristone (RR 0.73; 95% CI 0.55 to 0.97, 25 RCTs, n = 11,914, I = 0%, high-quality evidence). Comparative effectiveness of Cu-IUD versus mifepristoneThere was no conclusive evidence of a difference in the risk of pregnancy between the Cu-IUD and mifepristone (RR 0.33, 95% CI 0.04 to 2.74, 2 RCTs, n = 395, low-quality evidence). Adverse effectsNausea and vomiting were the main adverse effects associated with emergency contraception. There is probably a lower risk of nausea (RR 0.63, 95% CI 0.53 to 0.76, 3 RCTs, n = 2186 , I = 59%, moderate-quality evidence) or vomiting (RR 0.12, 95% CI 0.07 to 0.20, 3 RCTs, n = 2186, I = 0%, high-quality evidence) associated with mifepristone than with Yuzpe. levonorgestrel is probably associated with a lower risk of nausea (RR 0.40, 95% CI 0.36 to 0.44, 6 RCTs, n = 4750, I = 82%, moderate-quality evidence), or vomiting (RR 0.29, 95% CI 0.24 to 0.35, 5 RCTs, n = 3640, I = 78%, moderate-quality evidence) than Yuzpe. Levonorgestrel users were less likely to have any side effects than Yuzpe users (RR 0.80, 95% CI 0.75 to 0.86; 1 RCT, n = 1955, high-quality evidence). UPA users were more likely than levonorgestrel users to have resumption of menstruation after the expected date (RR 1.65, 95% CI 1.42 to 1.92, 2 RCTs, n = 3593, I = 0%, high-quality evidence). Menstrual delay was more common with mifepristone than with any other intervention and appeared to be dose-related. Cu-IUD may be associated with higher risks of abdominal pain than mifepristone (18 events in 95 women using Cu-IUD versus no events in 190 women using mifepristone, low-quality evidence).
AUTHORS' CONCLUSIONS
Levonorgestrel and mid-dose mifepristone (25 mg to 50 mg) were more effective than Yuzpe regimen. Both mid-dose (25 mg to 50 mg) and low-dose mifepristone(less than 25 mg) were probably more effective than levonorgestrel (1.5 mg). Mifepristone low dose (less than 25 mg) was less effective than mid-dose mifepristone. UPA was more effective than levonorgestrel.Levonorgestrel users had fewer side effects than Yuzpe users, and appeared to be more likely to have a menstrual return before the expected date. UPA users were probably more likely to have a menstrual return after the expected date. Menstrual delay was probably the main adverse effect of mifepristone and seemed to be dose-related. Cu-IUD may be associated with higher risks of abdominal pain than ECPs.

Up to now, limited studies have been done to evaluate the effect of sexual activity during menstruation on the endometriosis. However, due to the menstrual-related symptoms of endometriosis, this study aimed to systematically review the published articles on the association between sexual activity through menstruation and endometriosis. This systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). This study examined all published observational studies on the association between sexual activity during menstruation and endometriosis, on the basis of the PICOS from conception until September 2021. The Newcastle-Ottawa Quality Assessment Scale was used to evaluate the quality of the articles. Also, Meta-analysis was conducted using Review Manager (RevMan 5.3). Out of the 1,905 retrieved articles of related databases, four studies comprised a total of 3641 patients (2251 cases and 1390 controls), which fulfilled the inclusion criteria, and equally encompassed high (2/4) and low (2/4) methodological quality, were reviewed. The results of all pooled studies showed that the probability of having sexual activity during menstruation is approximately two times higher in the women with endometriosis compared to women without endometriosis [odds ratio (OR)=1.80, 95% confidence interval (CI): 1.12 to 2.90, P=0.02, I2=78%, Tau=0.17, Chi2=13.72, P=0.003]. In this review, the sexual activity during menstruation was found to be an influencing factor for endometriosis. Due to the importance and complexity of endometriosis and the dearth of evidence on this topic, further studies with more robust designs are recommended.

Meta-Analysis
OBJECTIVE
To investigate the effectiveness and safety of tripterygium glycosides (TG) tablet for the treatment of Lupus nephritis (LN).
METHODS
Several databases were systematically searched including PubMed, Embase, Cochrane, Wiley, China National Knowledge Infrastructure Database, SinoMed and Wanfang Library till June 20, 2020. Revman5.3 was utilized to analyze the data according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement.
RESULTS
In total, 8 randomized controlled trials involving 583 participants were identified. Meta-analyses showed that, compared with glucocorticoids (GC) alone, the combination with TG tablet provided a statistically significant improvement in total remission (TR) ( = 1.27, 95% : 1.08-1.50, = 0.004), complete remission (CR) ( = 1.61, 95% : 1.05-2.47, = 0.03) and C3 levels ( = 0.27, 95% : 0.14-0.39, < 0.000 1), C4 levels ( = 0.12, 95% : 0.07-0.17, < 0.000 01). No significant differences were seen in TR, CR, proteinuria, serum creatinine, C3 and C4 (TR: = 1.00, 95% : 0.87-1.16, = 0.95; CR: = 1.10, 95% : 0.78-1.56, = 0.58; proteinuria levels: = -0.06, 95% : -0.13 to 0.01, = 0.10; serum creatinine levels: = -0.01, 95%: -7.36 to 7.35, = 1.00; C3 levels: = 0.01, 95%: -0.06 to 0.07, = 0.84; C4 levels: = -0.01, 95%: -0.03 to 0.01, = 0.49) between azathioprine (AZA) / leflomit (LEF) + GC and TG tablet + GC. Adverse events (hepatic dysfunction, nausea, vomitting) showed no statistical differences between the TG tablet + GC group and the GC group. There were more new onset of irregular menstruation in the TG tablet + GC group than those in the AZA + GC ( = 3.57, 95% : 1.40-9.11, = 0.008) /LEF+ GC ( = 6.69, 95% : 2.42-18.46, = 0.000 2) group, but leucopenia lower than those in AZA + GC group ( = 0.38, 95% : 0.17-0.85, = 0.02) and alopecia ( = 0.14, 95% : 0.03-0.77, = 0.02) and rash ( = 0.09, 95% : 0.01-0.69, = 0.02) lower than those in LEF + GC group.
CONCLUSIONS
This review indicates that TG tablet maybe effective in LN treatment. Nevertheless, adverse events cannot be ignored. Large sample, multi-center, high-quality clinical studies are needed to verify the exact effects and safety of TG tablet in treatment of LN.

Comparative Study Review
BACKGROUND
Heavy menstrual bleeding affects as many as one in three women and has negative physical, economic, and psychosocial impacts including activity limitations and reduced quality of life. The goal of treatment is to make menstruation manageable, and options include medical therapy or surgery such as endometrial ablation or hysterectomy. This review examined the evidence of effectiveness and cost-effectiveness of the 52-mg levonorgestrel-releasing intrauterine system (LNG-IUS) as a treatment alternative for idiopathic heavy menstrual bleeding.
METHODS
We conducted a systematic review of the clinical and economic evidence comparing LNG-IUS with usual medical therapy, endometrial ablation, or hysterectomy. Medline, EMBASE, Cochrane, and the Centres for Reviews and Dissemination were searched from inception to August 2015. The quality of the evidence was assessed according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group criteria. We also completed an economic evaluation to determine the cost-effectiveness and budget impact of the LNG-IUS compared with endometrial ablation and with hysterectomy. The economic evaluation was conducted from the perspective the Ontario Ministry of Health and Long-Term Care.
RESULTS
Relevant systematic reviews (n = 18) returned from the literature search were used to identify eligible randomized controlled trials, and 16 trials were included. The LNG-IUS improved quality of life and reduced menstrual blood loss better than usual medical therapy. There was no evidence of a significant difference in these outcomes compared with the improvements offered by endometrial ablation or hysterectomy. Mild hormonal side effects were the most commonly reported. The quality of the evidence varied from very low to moderate across outcomes. Results from the economic evaluation showed the LNG-IUS was less costly (incremental saving of $372 per person) and more effective providing higher quality-adjusted life years (incremental value of 0.05) compared with endometrial ablation. Similarly, the LNG-IUS costs less (incremental saving of $3,138 per person) and yields higher quality-adjusted life-years (incremental value of 0.04) compared with hysterectomy. Publicly funding LNG-IUS as an alternative to endometrial ablation and hysterectomy would result in annual cost savings of $3 million to $9 million and $0.1 million to $23 million, respectively, over the first 5 years.
CONCLUSIONS
The 52-mg LNG-IUS is an effective and cost-effective treatment option for idiopathic heavy menstrual bleeding. It improves quality of life and menstrual blood loss, and is well tolerated compared with endometrial ablation, hysterectomy, or usual medical therapies.

Review
Recent studies have reported inconclusive results regarding the therapeutic effects of Rosa damascena on the outcomes of primary dysmenorrhea (PD) and premenstrual syndrome (PMS). Hence, this study is aimed to summarize the findings of randomized controlled trials (RCTs) regarding the effects of this treatment on menstruation-related pain as the primary outcome and menstruation-related headache, fatigue, anxiety, and bloating as the secondary outcomes. This study evaluated parallel-group and cross-over RCTs on aromatherapy, topical treatment, or oral intake of R. damascena products for the treatment groups versus placebo, nontreated, or conventional treatment groups. Seven electronic databases (Web of Science Core Collection, Scopus, Embase, CENTRAL, CINAHL, SID, and MagIran) and one search engine (PubMed) were searched from inception to January 15, 2021. Of 1468 trials found in the initial search, 983 potentially relevant articles were screened by title and abstract. After examining the full-text of 13 studies for compliance with the inclusion criteria, seven studies were considered eligible for this review. A random-effects model was used to pool the data; otherwise, a narrative summary was presented. The retrieved studies were conducted on females with PD or PMS, aged 18-35 years. The total sample size of the intervention and comparator arms was 276 and 272. The results showed that R. damascena had a nonsignificant alleviating effect on the menstruation-related pain (weighted mean difference [WMD]: -0.47; 95% confidence interval [CI]: -1.25, 0.31; = 0.234). Such findings were also found for menstruation-related anxiety (WMD: -0.40; 95% CI: -0.91, 0.11; = 0.125). However, the treatment significantly reduced the menstruation-related headache (WMD: -0.42; 95% CI: -0.74, -0.11; = 0.008), fatigue (WMD: -0.48; 95% CI: -0.87, -0.09; = 0.015), and bloating (WMD: -0.72; 95% CI: -1.21, -0.22; = 0.005). Since R. damascena had no significant effects on menstruation-related pain and anxiety, further studies with improved methodological quality are suggested to evaluate the effects of the treatment on these symptoms, using different dosages and durations.

Review
BACKGROUND
Heavy menstrual bleeding and pain are common reasons women discontinue intrauterine device (IUD) use. Copper IUD (Cu IUD) users tend to experience increased menstrual bleeding, whereas levonorgestrel IUD (LNG IUD) users tend to have irregular menstruation. Medical therapies used to reduce heavy menstrual bleeding or pain associated with Cu and LNG IUD use include non-steroidal anti-inflammatory drugs (NSAIDs), anti-fibrinolytics and paracetamol. We analysed treatment and prevention interventions separately because the expected outcomes for treatment and prevention interventions differ. We did not combine different drug classes in the analysis as they have different mechanisms of action. This is an update of a review originally on NSAIDs. The review scope has been widened to include all interventions for treatment or prevention of heavy menstrual bleeding or pain associated with IUD use.
OBJECTIVES
To evaluate all randomized controlled trials (RCTs) that have assessed strategies for treatment and prevention of heavy menstrual bleeding or pain associated with IUD use, for example, pharmacotherapy and alternative therapies.
SEARCH METHODS
We searched CENTRAL, MEDLINE, Embase and CINAHL to January 2021.
SELECTION CRITERIA
We included RCTs in any language that tested strategies for treatment or prevention of heavy menstrual bleeding or pain associated with IUD (Cu IUD, LNG IUD or other IUD) use. The comparison could be no intervention, placebo or another active intervention.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trials for inclusion and risk of bias, and extracted data. Primary outcomes were volume of menstrual blood loss, duration of menstruation and painful menstruation. We used a random-effects model in all meta-analyses. Review authors assessed the certainty of evidence using GRADE.
MAIN RESULTS
This review includes 21 trials involving 3689 participants from middle- and high-income countries. Women were 18 to 45 years old and either already using an IUD or had just had one placed for contraception. The included trials examined NSAIDs and other interventions. Eleven were treatment trials, of these seven were on users of the Cu IUD, one on LNG IUD and three on an unknown type. Ten were prevention trials, six focused on Cu IUD users, and four on LNG IUD users. Sixteen trials had high risk of detection bias due to subjective assessment of pain and bleeding. Treatment of heavy menstrual bleeding Cu IUD Vitamin B1 resulted in fewer pads used per day (mean difference (MD) -7.00, 95% confidence interval (CI) -8.50 to -5.50) and fewer bleeding days (MD -2.00, 95% CI -2.38 to -1.62; 1 trial; 110 women; low-certainty evidence) compared to placebo. The evidence is very uncertain about the effect of naproxen on the volume of menstruation compared to placebo (odds ratio (OR) 0.09, 95% CI 0.00 to 1.78; 1 trial, 40 women; very low-certainty evidence). Treatment with mefenamic acid resulted in less volume of blood loss compared to tranexamic acid (MD -64.26, 95% CI -105.65 to -22.87; 1 trial, 94 women; low-certainty evidence). However, there was no difference in duration of bleeding with treatment of mefenamic acid or tranexamic acid (MD 0.08 days, 95% CI -0.27 to 0.42, 2 trials, 152 women; low-certainty evidence). LNG IUD The use of ulipristal acetate in LNG IUD may not reduce the number of bleeding days in 90 days in comparison to placebo (MD -9.30 days, 95% CI -26.76 to 8.16; 1 trial, 24 women; low-certainty evidence). Unknown IUD type Mefenamic acid may not reduce volume of bleeding compared to Vitex agnus measured by pictorial blood assessment chart (MD -2.40, 95% CI -13.77 to 8.97; 1 trial; 84 women; low-certainty evidence). Treatment of pain Cu IUD Treatment with tranexamic acid and sodium diclofenac may result in little or no difference in the occurrence of pain (OR 1.00, 95% CI 0.06 to 17.25; 1 trial, 38 women; very low-certainty evidence). Unknown IUD type Naproxen may reduce pain (MD 4.10, 95% CI 0.91 to 7.29; 1 trial, 33 women; low-certainty evidence). Prevention of heavy menstrual bleeding Cu IUD We found very low-certainty evidence that tolfenamic acid may prevent heavy bleeding compared to placebo (OR 0.54, 95% CI 0.34 to 0.85; 1 trial, 310 women). There was no difference between ibuprofen and placebo in blood volume reduction (MD -14.11, 95% CI -36.04 to 7.82) and duration of bleeding (MD -0.2 days, 95% CI -1.40 to 1.0; 1 trial, 28 women, low-certainty evidence). Aspirin may not prevent heavy bleeding in comparison to paracetamol (MD -0.30, 95% CI -26.16 to 25.56; 1 trial, 20 women; very low-certainty evidence). LNG IUD Ulipristal acetate may increase the percentage of bleeding days compared to placebo (MD 9.50, 95% CI 1.48 to 17.52; 1 trial, 118 women; low-certainty evidence). There were insufficient data for analysis in a single trial comparing mifepristone and vitamin B. There were insufficient data for analysis in the single trial comparing tranexamic acid and mefenamic acid and in another trial comparing naproxen with estradiol. Prevention of pain Cu IUD There was low-certainty evidence that tolfenamic acid may not be effective to prevent painful menstruation compared to placebo (OR 0.71, 95% CI 0.44 to 1.14; 1 trial, 310 women). Ibuprofen may not reduce menstrual cramps compared to placebo (OR 1.00, 95% CI 0.11 to 8.95; 1 trial, 20 women, low-certainty evidence).
AUTHORS' CONCLUSIONS
Findings from this review should be interpreted with caution due to low- and very low-certainty evidence. Included trials were limited; the majority of the evidence was derived from single trials with few participants. Further research requires larger trials and improved trial reporting. The use of vitamin B1 and mefenamic acid to treat heavy menstruation and tolfenamic acid to prevent heavy menstruation associated with Cu IUD should be investigated. More trials are needed to generate evidence for the treatment and prevention of heavy and painful menstruation associated with LNG IUD.

Meta-Analysis
OBJECTIVES
This study presents a scoping review of evidence relating to knowledge and experiences of puberty and menstruation among females aged 10-14 years in low- and middle-income countries.
METHODS
Forty-four items from 12 countries were identified from a systematic scoping review and screening of 8083 items. Included studies were quality assessed.
RESULTS
A majority (40/44) of studies used school-based samples, and fifteen studies reported on interventions. Girls had inadequate knowledge about menstruation; menarche as a trigger for girls learning about menstruation was common. Adolescents struggled with menstrual hygiene. Negative emotions were associated with menarche and menstrual management. A minority of studies dealt explicitly with puberty. Most girls obtained information about menstruation and/or puberty from their mothers, although mothers were not necessarily girls' preferred source for learning about these topics.
CONCLUSIONS
Young adolescent girls are under-prepared for puberty and menstruation. Predominantly school-based studies mean we know little about young out-of-school adolescents. The evidence base lags behind the rise in interest from practitioners as well as the development (and evaluation) of puberty and/or menstruation interventions.

Review
BACKGROUND
Polycystic ovary syndrome (PCOS) is a common endocrine disorder that affects women of reproductive age and female adolescents. The diagnosis of PCOS is difficult during puberty due to overlapping of the criteria with normal variations of menstruation during this age period. There are insufficient data on the gut microbiome and PCOS and potential mechanisms linking the two. The present systematic review aimed to detect dysbiosis patterns in youth with PCOS, compared with healthy controls.
METHODS
One hundred seventy-eight studies were identified by a databases search and sixty-eight by a full-text assessment for eligibility; four were included in the systematic review and underwent quality control.
RESULTS
The results of the study were controversial in accordance to findings from the literature. A change in gut microbiome α diversity was found in PCOS adolescents, with no significant alterations in β diversity. Almost all studies found Firmicutes, Bacteroidetes, and Actinobacteria in abundance in both groups, with changes in family composition and fluctuations at the phylum level. A statistically significant association between these changes and clinical or biochemical features of the syndrome was described.
CONCLUSIONS
This systematic review confirmed gut microbiota dysbiosis in youth with PCOS. However, further data are needed to clarify these changes and to build a strategy to prevent the syndrome.

To describe the available knowledge on vulvo-perineal endometriosis including its diagnosis, clinical management and recurrence rate. We followed the PRISMA guidelines for Systematic Reviews and our study was prospectively registered with PROSPERO (CRD42020202441). The terms " and " or " were used as keywords. Cochrane Library, Medline/Pubmed, Embase and Clinicaltrials.gov were searched. Papers in English, Spanish, Portuguese, French or Italian from inception to July 30, 2020 were considered. Reference lists of included articles and other literature source such as Google Scholar were also manually scrutinized in order to identify other relevant studies. Two independent reviewers screened potentially eligible studies according to inclusion criteria. Out of 539 reports, 90 studies were eligible including a total of 283 patients. Their mean age was 32.7 ± 7.6 years. Two hundred sixty-three (95.3%) presenting with vulvo-perineal endometriosis have undergone either episiotomy, perineal trauma or vaginal injury or surgery. Only 13 patients (4.7%) developed vulvo-vaginal endometriosis spontaneously i.e., without any apparent condition favoring it. The reasons that motivated the patients to take medical advice were vulvo-perineal cyclical pain increasing during menstruations (98.2% of the patients, = 278). Out of the 281 patients for whom a clinical examination was described, 274 patients (97.5%) showed a vulvo-perineal nodule, mass or swelling while six presented with bluish cutaneous lesions (2.1%) and 1 with bilateral polyps of the labia minora (0.4%). All but one patients underwent surgical excision of their lesions but only 88 patients (28.1%) received additional hormonal therapy. The recurrence rate was 10.2% (29 patients) considering a median follow-up period of 10 months (based on 61 studies). In conclusion, vulvo-perineal endometriosis is a rare entity with approximately 300 cases reported in the literature since 1923. With the available knowledge shown in this systematic review, we encourage all practitioners to think about perineal endometriosis in case of perineal cyclical pain with or without previous perineal damage. Diagnosis should be done with clinical exam, perineal ultrasound and pelvic MRI when available. In case of anal sphincter involvement, perianal ultrasound should be performed. Surgical excision of the lesion should be realized in order to remove the lesion and to confirm the diagnosis histologically. Hormonal treatment could be proposed to attempt to decrease the size of a large lesion before surgery or to avoid recurrence of the lesion. As evidence-based approach to the diagnosis, treatment and recurrence rate of affected patients remains a challenge given its low prevalence, the variations in management found in the articles included and the limited quality of available studies, we suggest that a prospective database on vulvo-perineal endometriosis should be generated to increase knowledge but also awareness among healthcare professionals and optimize patients' care. https://www.crd.york.ac.uk/prospero/, identifier: CRD42020202441.
