Abstract
Endometriosis-related infertility remains a therapeutic challenge. A burning issue in this field of research is determining whether pre-assisted reproductive technology (ART) surgery may be of some benefit in terms of reproductive outcomes. This systematic review and meta-analysis aimed at comparing ongoing pregnancy rates (OPR) and/or live birth rates (LBR) in patients who underwent endometriosis surgery before ART (IVF/ICSI) in comparison with patients who underwent first-line ART (IVF/ICSI). Searches were conducted from January 1990 to June 2021 on PubMed, Embase, and Cochrane Library using the following search terms: endometriosis, surgery, reproductive outcomes, and IVF/ICSI. The primary outcomes were OPR or LBR. A total of 19 studies were included in the meta-analysis. No statistically significant differences in LBR [0.91[0.63, 1.30]; I2 = 66%; n = 11], OPR [1.28[0.66, 2.49]; I2 = 60%; n = 3], and early pregnancy loss rate [0.88[0.62, 1.25]; I2 = 0%; n = 7] per cycle were found when comparing patients who underwent endometriosis surgery before IVF/ICSI and those who did not. After the exclusion of the studies with high risks of bias, the LBR per cycle was significantly reduced in the case of surgical treatment before IVF/ICSI [0.53[0.33, 0.86]; I2 = 30%; n = 4]. These data urge the clinician to carefully weigh the pros and cons before referring infertile patients with endometriosis to surgery before IVF, highlighting the key role of multidisciplinary referral centers.

Indirect markers of oocyte quality in patients with ovarian endometriosis undergoing IVF/ICSI: a systematic review and meta-analysis. Reprod Biomed Online 2024; 49:104075. [PMID: 38943812 DOI: 10.1016/j.rbmo.2024.104075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 04/08/2024] [Accepted: 04/16/2024] [Indexed: 07/01/2024]
Abstract
This systematic review and meta-analysis aimed to evaluate the impact of ovarian endometriomas (OMA) on indirect markers of oocyte quality in patients undergoing IVF, compared with women without anatomical or functional ovarian abnormalities. The search spanned original randomized controlled trials, case-control studies and cohort studies published in MEDLINE, the Cochrane Controlled Trials Register and the ClinicalTrials.gov database up to October 2023. Thirty-one studies were included in the meta-analysis, showing no significant differences in fertilization (OR 1.10, 95% CI 0.94-1.30), blastulation (OR 0.86, 95% CI 0.64-1.14) and cancellation (OR 1.06, 95% CI 0.78-1.44) rates. However, patients with OMA exhibited significantly lower numbers of total and mature (metaphase II) oocytes retrieved (mean difference -1.59, 95% CI -2.25 to -0.94; mean difference -1.86, 95% CI -2.46 to -1.26, respectively), and lower numbers of top-quality embryos (mean difference -0.49, 95% CI -0.92 to -0.06). The Ovarian Sensitivity Index was similar between the groups (mean difference -1.55, 95% CI -3.27 to 0.18). The lack of data published to date prevented meta-analysis on euploidy rate. In conclusion, although the presence of OMA could decrease the oocyte yield in patients undergoing IVF/intracytoplasmic sperm injection, it does not appear to have an adverse impact on oocyte quality.

Abstract
Endometriosis is a complex medical condition with a high prevalence in women of reproductive age. Fertility is compromised in patients with endometriosis, and success in IVF treatments has been a challenge leading to evaluation of different stimulation protocols. The long-standing debate between GnRH agonist long protocols and short GnRH antagonist protocols is being resolved in favor of the latter, since in addition to presenting equivalent results with respect to the traditional option, they have the additional benefit of safety. The good results derived from vitrification techniques have led to the development of new stimulation strategies, such as progestin-primed ovarian stimulation (PPOS), with a greater degree of approval among patients. None of the stimulation protocols currently applied in women with endometriosis has been shown to be superior, so early intervention with an Assisted Reproduction treatment, regardless of the chosen protocol, can provide these women with good chances of motherhood. Women with endometrioma should be counseled for fertility preservation before planned ovarian endometrioma excision. The number of cryopreserved oocytes or embryos can be increased by repeated cycles.

Abstract
Objectives The effects of laparoscopic surgical management in women with stage III/IV endometriosis remain controversial. The standard extent of resection for stage III/IV endometriosis with deep endometriosis to treat endometriosis-associated infertility is debatable. This study aimed to assess the postoperative pregnancy outcomes following a routine surgical intervention for stage III/IV endometriosis patients. Materials and Methods Patients with stage III/IV endometriosis who underwent conservative laparoscopic surgery at our hospital between January 2010 and December 2018 were retrospectively analyzed. Statistical analyses were performed to determine the correlations between endometriosis features and postoperative pregnancy outcomes. Results Of 256 patients enrolled, 94 wished to conceive. Exclusion criteria: ≥40 years, adenomyosis, partners with infertility issues. Finally, 71 women were included. The overall postoperative pregnancy rate was 76.1% (n = 54): 49 and five from non-assisted reproductive technology (ART) and ART, respectively. The postoperative pregnancy rate in patients diagnosed with infertility presurgery (40/71) was 70.0% (n = 28): 24 (non-ART) and four (ART). The endometriosis fertility index (EFI) score was higher in the pregnant than in the nonpregnant group (P = 0.03). The EFI score and surgical score of EFI were higher in the non-ART than in the ART group (P = 0.04; P = 0.02); in the infertile group, they were higher in the pregnant than in the nonpregnant group (P = 0.018; P = 0.027). Conclusion Our postoperative pregnancy rate after conservative laparoscopic surgery for patients with stage III/IV endometriosis compared favorably with previous reports. EFI was a significant predictor of postoperative pregnancy. Our surgical approach to maintain a high surgical score of EFI might help treat endometriosis-associated infertility.

Abstract
Anti-Müllerian hormone (AMH) and antral follicular count (AFC) decrease in women with ovarian endometrioma (OMA) and in vitro fertilization (IVF). In addition, these parameters drop even further when women with OMA undergo surgery. In this study, the primary aim was to compare the reproductive variables in IVF-treated women with and without endometriosis. The secondary aim was to explore if the reproductive variables were modified by endometrioma surgery. In this retrospective study, 244 women undergoing IVF were enrolled at the Hospital Universitario La Paz (Madrid, Spain). Women were categorized as OMA not surgically treated (OMA; n = 124), OMA with surgery (OMA + S; n = 55), and women with infertility issues not related to OMA (control; n = 65). Demographic and clinical variables, including age, body mass index (BMI), and reproductive (AMH, AFC, number of extracted oocytes, and transferred embryos) and obstetrical data (biochemical pregnancy and fetal heart rate at 6 weeks) were collected. Adjusted logistic regression models were built to evaluate reproductive and pregnancy outcomes. The models showed that women with OMA (with and without surgery) had significantly decreased levels of AMH and AFC and numbers of cycles and C + D embryos. Women with OMA + S had similar rates of pregnancy to women in the control group. However, women with OMA had lower biochemical pregnancy than controls (aOR = 0.08 [0.01; 0.50]; p-value = 0.025). OMA surgery seems to improve pregnancy outcomes, at least until 6 weeks of gestation. However, it is important to counsel the patients about surgery expectations due to the fact that endometrioma itself reduces the quality of oocytes.

Abstract
BACKGROUND Endometriosis is a common cause for infertility. Decreased ovarian reserve due to pathology or surgical management can reduce the chances of natural pregnancy and limit the effectiveness of controlled ovarian stimulation during fertility treatment. Cryopreservation of oocytes or ovarian cortex prior to surgery or before loss of follicular capital is a strategy to preserve fecundity. METHODS An online survey was sent to reproductive specialists and gynecological surgeons representing major centers of reproductive medicine in Europe to investigate current fertility preservation practices for endometriosis patients. RESULTS Of 58 responses, 45 (77.6%) in 11/13 countries reported the existence of endometriosis management guidelines, of which 37/45 (82.2%) included treatment recommendations for infertile patients. Most centers (51.7%) reserved fertility counselling for severe endometriosis (large endometriomas with or without deep endometriosis) while 15.5% of centers did not offer fertility preservation for endometriosis. CONCLUSIONS To address non-uniformity in available guidelines and the diversity in fertility preservation practices, we propose an algorithm for managing patients with severe endometriosis most likely to be impacted by reduced ovarian reserve. Improved awareness about the possibilities of fertility preservation and clear communication between gynaecological surgeons and reproductive medicine specialists is mandatory to address the unmet clinical need of preventing infertility in women with endometriosis.

Abstract
Although a wealth of data has been published regarding fertility preservation (FP) in women with malignant diseases who receive gonadotoxic treatment, the role of FP in non-malignant conditions has been studied to a much lesser extent. These include benign haematological, autoimmune, and genetic disorders, as well as a multitude of benign gynaecological conditions (BGCs) that may compromise ovarian reserve and/or reproductive potential due to pathogenic mechanisms or as a result of medical or surgical treatments. Alongside accumulating data that document the reproductive potential of cryopreserved oocytes and ovarian tissue, there is potential interest in FP for women with BGCs at risk of infertility; however, there are currently insufficient data about FP in women with BGCs to develop guidelines for clinical practice. The purpose of this article is to appraise the available evidence regarding FP for BGC and discuss potential strategies for FP based on estimated ovarian impairment and on short-term and long-term reproductive goals of patients. Cost-effectiveness considerations and patients' perspectives will also be discussed.

Abstract
Endometrioma (OMA) is the most common subtype of endometriosis, in which the endometriotic lesions are implanted in the ovary. Women with OMA are usually associated with infertility, presenting with reduced ovarian reserve, low oocyte quantity and quality, and poor fertility outcomes. However, the underlying pathological mechanisms in OMA-related infertility are still unclear. Due to the limitations and ethical issues of human studies in reproduction, animal models that recapitulate OMA characteristics and its related infertility are critical for mechanistic studies and subsequent drug development, preclinical testing, and clinical trials. This review summarized the investigations of OMA-related infertility based on previous and latest endometrioma models, providing the possible pathogenesis and potential therapeutic targets for further studies.

Abstract
OBJECTIVE The present study aimed to evaluate and compare the assisted reproductive technique (ART) outcomes of women with endometriomas either with or without prior endometrioma surgery. MATERIALS AND METHODS A total of 122 women with endometriomas underwent intracytoplasmic sperm injection-embryo transfer (ICSI-ET) at a tertiary IVF Center, between 2014 and 2019, were included in this retrospective study. Of this group, 38 patients had recurrent endometriomas and 84 patients had primary endometrioma without a previous endometrioma surgery. The outcomes of ART treatment including cancellation rates before ET, numbers of oocytes obtained, implantation, clinical pregnancy and live birth rates were compared between the groups. A logistic regression model including potential confounders as age and presence of male factor infertility was used to evaluate the possible effect of recurrent endometriomas on the live birth. RESULTS The baseline characteristics of the groups were similar. The poor ovarian response rate, defined as the harvest of fewer than four oocytes, was identified in 35.7% and 42.1% of primary and recurrent endometrioma groups, respectively. The implantation (27.2 ± 42.7% vs 24.1 ± 41.4%, P = .74), clinical pregnancy/ET (30.9% vs 27.6%, P = .93 ) and live birth rates/ET (22.1% vs 17.2%, P = .79) CONCLUSION: The ART outcomes of patients with primary and recurrent endometriomas do not seem different in terms of response to ovarian stimulation and live birth rates after ICSI. These results may indicate that the recurrence of the endometrioma might not have a further detrimental effect on ART outcome than the disease itself.

Abstract
RESEARCH QUESTION What prognostic factors relate to a high oocyte yield in fertility preservation for women affected by endometriosis? DESIGN Observational cohort study conducted in a tertiary care university hospital between April 2015 and January 2019. Women who had undergone fertility preservation with ovarian stimulation for oocytes and embryo vitrification for endometriosis were included. Prognostic factors associated with the number of oocytes retrieved after the first ovarian stimulation were analysed. RESULTS A total of 146 women who had undergone 258 ovarian stimulation cycles were included; 82 (56.2%) had undergone more than one ovarian stimulation cycle; 72.6% had at least one endometrioma lesion; and 36.3% had previously undergone surgery for endometriosis. After adjustment by multiple linear regression, the factors that significantly reduced the number of oocytes retrieved were previous history of surgery for ovarian endometriosis (coefficient -1.08; 95% CI -2.02 to -0.15; P = 0.024); women's age (-0.21; 95% CI -0.41 to -0.01; P = 0.039); and total dose of gonadotrophin used (-0.01; 95% CI -0.01 to -0.00; P = 0.047). Anti-Müllerian hormone serum level and gravidity positively correlated with an increase in the number of oocytes retrieved (1.65; 95% CI 1.13 to 2.17; P < 0.001 and 3.30; 95% CI 0.91 to 5.68; P = 0.007, respectively) after the first ovarian stimulation cycle. CONCLUSION A history of surgery for ovarian endometriosis was associated with significantly lower oocyte yields. Fertility preservation should be integrated into endometriosis management. Fertility preservation should ideally be made available to the patient before surgery.

Dinsdale NL, Crespi BJ. Endometriosis and polycystic ovary syndrome are diametric disorders. Evol Appl 2021; 14:1693-1715. [PMID: 34295358 PMCID: PMC8288001 DOI: 10.1111/eva.13244] [Citation(s) in RCA: 31] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 04/09/2021] [Accepted: 04/10/2021] [Indexed: 12/15/2022] Open
Abstract
Evolutionary and comparative approaches can yield novel insights into human adaptation and disease. Endometriosis and polycystic ovary syndrome (PCOS) each affect up to 10% of women and significantly reduce the health, fertility, and quality of life of those affected. PCOS and endometriosis have yet to be considered as related to one another, although both conditions involve alterations to prenatal testosterone levels and atypical functioning of the hypothalamic-pituitary-gonadal (HPG) axis. Here, we propose and evaluate the novel hypothesis that endometriosis and PCOS represent extreme and diametric (opposite) outcomes of variation in HPG axis development and activity, with endometriosis mediated in notable part by low prenatal and postnatal testosterone, while PCOS is mediated by high prenatal testosterone. This diametric disorder hypothesis predicts that, for characteristics shaped by the HPG axis, including hormonal profiles, reproductive physiology, life-history traits, and body morphology, women with PCOS and women with endometriosis will manifest opposite phenotypes. To evaluate these predictions, we review and synthesize existing evidence from developmental biology, endocrinology, physiology, life history, and epidemiology. The hypothesis of diametric phenotypes between endometriosis and PCOS is strongly supported across these diverse fields of research. Furthermore, the contrasts between endometriosis and PCOS in humans parallel differences among nonhuman animals in effects of low versus high prenatal testosterone on female reproductive traits. These findings suggest that PCOS and endometriosis represent maladaptive extremes of both female life-history variation and expression of sexually dimorphic female reproductive traits. The diametric disorder hypothesis for endometriosis and PCOS provides novel, unifying, proximate, and evolutionary explanations for endometriosis risk, synthesizes diverse lines of research concerning the two most common female reproductive disorders, and generates future avenues of research for improving the quality of life and health of women.

Abstract
Objectives: Data regarding whether the assisted reproductive technologies (ART) outcome of patients with decreased ovarian reserve (DOR) secondary to an endometrioma surgery differs from that of patients with DOR secondary to other etiologies is limited. The aim of this study was to compare the ART outcomes of DOR patients diagnosed by Bologna criteria secondary to a previous endometrioma surgery with DOR patients without a history of an endometrioma surgery. Methods: This retrospective cohort study was conducted in the assisted reproduction unit of a tertiary research and education hospital. Medical records of the patients with DOR were reviewed retrospectively. Group I included 23 cycles of DOR patients secondary to a previous endometrioma surgery and Group II consisted of 260 cycles of DOR patients without a history of endometrioma surgery. Results: No significant difference was demonstrated between groups regarding demographic features except for the age (32 (24–41) in Group I vs 35 (23–47) in Group II, p = 0.031). The data comparing the controlled ovarian stimulation parameters and ART outcomes showed similar results in both groups. No statistically significant difference was found between groups regarding pregnancy rates per transfer (23% vs 22.2 %) and per cycle (13% vs 15.4%) ( p > 0.05). Conclusion: Cycle outcomes of DOR patients secondary to an endometrioma surgery did not differ from that of DOR without an endometrioma surgery history.

Abstract
Endometrioma is the cystic lesion of ovaries originating from endometrial glands and stroma; it is identified in 17-44% of patients with endometriosis. Numerous existing studies have reported the association between endometrioma and infertility. However, an absolute cause-effect association requires further confirmation. Available evidence has suggested that ovarian reserve may be impaired by spatial occupation influences, local reaction or both, affecting the reproductive health of females. Given the increased focus on the pathophysiological mechanisms of endometrioma, surgical excision has commonly been considered to avoid further ovarian damage. However, the potential adverse effect of this surgery on the ovarian reserve has recently become a focal point. Whether or not surgical excision can facilitate subsequent conception in young females planning to be pregnant is controversial. As shown in the present review on the effects of endometrioma and its removal in females requiring assisted reproductive technology, prior surgery for endometrioma may not improve assisted fertility results and may further decrease the number of oocytes retrieved in the affected females. Subsequent studies are needed to ascertain the optimal management of infertility in the setting of endometriomas.

Abstract
Studies suggest that the presence of endometriosis may lead to impaired ovarian reserve, while results evaluating the changes in antral follicle count (AFC) in endometriosis remain controversial. A systematic search returned 15 studies, of which nine compared AFC between patients with and without endometriosis, five articles reported differences in AFC between affected and unaffected ovaries in patients with unilateral ovarian endometriosis and one reported both of the above two situations. Overall results showed a significant decrease in AFC and anti-Müllerian hormone (AMH) and increase in serum FSH concentrations in patients with endometriosis when compared with controls. Additionally, the AFC for the ovary with the endometrioma was also significantly lower than that of the contralateral ovary in patients with unilateral ovarian endometriosis. Moreover, it appears that the AFC in patients with endometriosis where the ovaries are not affected or in early stage were not significantly different in the control group. These findings demonstrate that endometriosis is associated with reduced AFC and AMH and elevated serum concentrations of FSH, suggesting a reduction in ovarian reserve in patients with endometriosis, especially in those with ovarian endometrioma and advanced stage.

Abstract
PURPOSE To investigate the potential role of Bone morphogenetic protein 1 (BMP1) in endometriosis lesions. METHODS Endometriosis model in mice was established. The expression of BMP1-3 expression in mice of endometriosis lesions was evaluated. The effect of the treatment with anti-BMP1 antibodies on the expression of MMP2, MMP9, TGF-β, IL-17, IL-1β, Col1a1 and Col1a2 levels in mice was evaluated. In endometriosis cell model, the expression of IL-17, IL-1β, MMP2 and MMP9 levels and MIF, YWHAZ, β-catenin and CAP39 mRNA levels was also detected. RESULTS The expression of BMP1-3 expression was upregulated in mice of endometriosis lesions (p < 0.01). Treatment with anti-BMP1 antibodies dose-dependently reduced MMP2, MMP9, TGF-β, IL-17, IL-1β, Col1a1 and Col1a2 levels in mice (p < 0.01). Treatment with anti-BMP1 antibodies suppressed TGF-β/PI3K/Akt signaling pathway. In vitro cell, si-BMP1 suppressed TGF-β/PI3K/Akt signaling pathway. CONCLUSION The data support the hypothesis that the inhibition of BMP1 is involved in the pathogenesis of endometriosis lesions.

Abstract
RESEARCH QUESTION Does the presence of ovarian endometriomas affect ovarian response to ovarian stimulation after adjusting for age and ovarian reserve markers? DESIGN This retrospective cross-sectional study compared the ovarian response between patients with ovarian endometriomas and women with other infertility factors undergoing their first ovarian stimulation for IVF/intracytoplasmic sperm injection (ICSI). An age-specific nomogram model for the number of oocytes retrieved was built for both groups, and ovarian response was compared after adjusting for age, gonadotrophin dose, anti-Mullerian hormone (AMH) concentration and antral follicle count (AFC). RESULTS A total of 923 patients were included: 101 women with at least one ovarian endometrioma, and 822 patients with other infertility factors. Comparisons of the nomograms for the number of oocytes retrieved demonstrated that response was significantly lower for women with endometrioma when the results were adjusted for age the z-score for the number of oocytes retrieved (-0.49 ± 0.71 versus -0.20 ± 0.86; 95% confidence interval [CI] -0.47 to -0.12) and also after adjustment for the total dose of gonadotrophins and AMH values (z-score mean difference -0.338; 95% CI -0.54, -0.14). When the z-score was adjusted for gonadotrophin dose and AFC, the number of oocytes retrieved was comparable between the two groups (z-score mean difference -0.038; 95% CI -0.34 to 0.27). CONCLUSIONS Ovarian response after ovarian stimulation for IVF/ICSI in women with endometriomas is significantly lower than in controls after adjusting for age, gonadotrophin dose and AMH. Dose and protocol selection for ovarian stimulation in patients with endometrioma should be based on AFC rather than AMH, as the latter may be overestimated.

Abstract
Aims: To determine the impact of advanced endometriosis (EMS) on in vitro fertilization/intracytoplasmic sperm injection and frozen-thawed embryo transfer (IVF/ICSI-FET) outcomes and analyze the influencing factors. Methods: A retrospective study was conducted on sterile women with ovarian endometriomas (OMAs), including patients who underwent laparoscopic cystectomy (n = 224, 224 IVF/ICSI cycles, 205 FET cycles) and aspiration (n = 139, 139 IVF/ICSI cycles, 148 FET cycles); peritoneal EMS (n = 96, 96 IVF/ICSI cycles, 89 FET cycles); and tubal factors (n = 360, 360 IVF/ICSI cycles, 474 FET cycles). Our main outcomes included the number of MII oocytes retrieved, fertilization rate, the number of viable embryos, viable embryo rate per oocyte retrieved in oocyte retrieval cycles, and clinical pregnancy rate per transfer, live birth rate per transfer, and cumulative clinical pregnancy rate of this oocyte retrieval cycle in FET cycles. Finally, binary logistic regression analysis was performed to generate a prediction model for cumulative clinical pregnancy. Results: The results showed that significantly fewer MII oocytes retrieved and viable embryos and lower viable embryo rate and cumulative clinical pregnancy rate were observed in women with EMS compared with the control. Women with peritoneal EMS had lower fertilization rate and viable embryo rate per oocyte retrieved than patients with OMA (all p < 0.05). However, the pregnancy outcomes were not significantly different between the two phenotypes. The patients who underwent laparoscopic cystectomy had fewer MII oocytes retrieved and viable embryos compared with those with intact endometrioma(s) but no significant difference in pregnancy outcomes between the two types of OMA patients. By binary logistic regression analysis, antral follicle count (AFC) was found to be an independent factor associated with cumulative clinical pregnancy in this oocyte retrieval cycle (odds ratio = 1.054; 95% confidence interval, 1.011-1.100; p = 0.014), and the AFC prediction model of cumulative clinical pregnancy was established, with an area under the curve of 0.60. Conclusions: Our data supported that advanced EMS has negative effect on cumulative clinical pregnancy per oocyte retrieval cycle, and AFC is an independent predictor, which is mainly caused by poor ovarian response associated with OMA per se or its surgery and the damage of peritoneal EMS to oocyte maturation.
