Surgical Management of Ovarian Endometrioma: Impact on Ovarian Reserve Parameters and Reproductive Outcomes. J Clin Med 2023; 12:5324. [PMID: 37629367 PMCID: PMC10455819 DOI: 10.3390/jcm12165324] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2023] [Revised: 08/08/2023] [Accepted: 08/14/2023] [Indexed: 08/27/2023] Open
Abstract
Ovarian endometriomas have a negative impact on a patient's reproductive potential and are likely to cause a reduction in ovarian reserve. The most commonly employed ovarian reserve parameters are anti-Müllerian hormone (AMH) and antral follicular count (AFC). Surgical management options of endometrioma include cystectomy, ablative methods, ethanol sclerotherapy and combined techniques. The optimal surgical approach remains a matter of debate. Our review aimed to summarize the literature on the impact of surgical management of endometrioma on AMH, AFC and fertility outcomes. Cystectomy may reduce recurrence rates and increase chances of spontaneous conception. However, a postoperative reduction in AMH is to be anticipated, despite there being evidence of recovery during follow-up. The reduction in ovarian reserve is likely multi-factorial. Cystectomy does not appear to significantly reduce, and may even increase, AFC. Ablative methods achieve an ovarian-tissue-sparing effect, and improved ovarian reserve, compared to cystectomy, has been demonstrated. A single study reported on AMH and AFC post sclerotherapy, and both were significantly reduced. AMH levels may be useful in predicting the chances of conception postoperatively. None of the aforementioned approaches has a clearly demonstrated superiority in terms of overall chances of conception. Surgical management of endometrioma may, overall, improve the probability of pregnancy. Evidence on its value before medically assisted reproduction (MAR) is conflicting; however, a combination of surgery followed by MAR may achieve the optimal fertility outcome. In view of the complexity of available evidence, individualization of care, combined with optimal surgical technique, is highly recommended.

Abstract
Several mechanisms have been implicated in the pathogenesis of endometriosis-related infertility. For patients considering surgery, the risk of iatrogenic injury is among the most important factors in the context of fertility preservation, along with age and individual reproductive goals. In the case of endometrioma excision, evidence overwhelmingly demonstrates the negative impact of surgery on ovarian reserve, with significant reductions in antimullerian hormone (up to 30% in unilateral versus up to 44% in bilateral endometriomas). The surgical endometriosis patient should be thoroughly counseled regarding fertility preservation and discussion should include tissue, embryo, and oocyte cryopreservation options. For the latter, data support cryopreservation of 10-15 oocytes in women ≤35 years and over 20 for those >35 years for a realistic chance to achieve one or more live births. When performing surgical interventions for endometriosis, reproductive surgeons should employ fertility-conserving surgical methods to reduce the likelihood of postoperative iatrogenic diminished ovarian reserve.

Abstract
PURPOSE This study aims to assess the impact of endometrioma on patients who undergo ART treatment due to endometriosis. METHODS A retrospective study was conducted on women ≤ 40 years of age who underwent ART treatment at an academic medical center between January 2014 and December 2020. Two-hundred-and-eight women had received IVF/ICSI treatment due to endometriosis and there were 89 patients presence of endometrioma. Patients were further divided into primary endometrioma, recurrent endometrioma and those having received cystectomy for endometrioma prior to IVF/ICSI. The control group included 624 infertile women without endometriosis. RESULTS In the endometrioma subgroup (B) the blastocyst formation rate was significantly lower when compared with the endometriosis (A) and control groups (C). The cumulative live birth rates (CLBRs) (60.5% versus 49.4% versus 56.9%, p = 0.194 in A versus B, p = 0.406 in A versus C, p = 0.878 in B versus C) were comparable. Multiple logistic regression analysis revealed that female age, total FSH dose and blastocyst formation rate were the significant variables in predicting CLBR (OR 0.89, CI 0.80-0.99, p < 0.025, OR 0.68 CI 0.53-0.88, p = 0.003 and OR 30.04, CI 9.93-90.9, p < 0.001, respectively). The CLBRs were comparable at 47.1%, 60% and 57.9% in the primary endometrioma, s/p cystectomy and recurrent endometrioma group. CONCLUSION Although the blastocyst formation rate was lower in the endometrioma group, CLBR was not worse than those who were in the endometriosis or control group. Cystectomy for endometrioma did not alter IVF/ICSI outcomes if the ovarian reserve was comparable. Recurrent endometrioma did not worsen IVF/ICSI outcomes than primary endometrioma.

Abstract
OBJECTIVE To evaluate the combined effects of age and endometriosis on ovarian reserve in women with infertility. METHODS We conducted a cross-sectional study using an institutional database. Women with sonographic, laparoscopic, or histologic evidence of endometriosis were defined as the study group and the remaining women served as a control group. We evaluated demographic and clinical characteristics of the groups as a whole and stratified the patients into those aged 35 years or older and those younger than 35 years at the time of ovarian reserve testing. RESULTS Of a total of 656 women included in the final analysis, 71 women had a diagnosis of endometriosis. When compared with women without endometriosis, the median anti-Müllerian hormone (AMH) and antral follicular count (AFC) values were significantly lower in the group of women with endometriosis-median 2.1 ng/ml (interquartile range [IQR] 1.1-3.9) versus 1.2 ng/ml (IQR 0.6-2.4; P < 0.001) for AMH and 14 follicles (IQR 8-23) versus 7 follicles (IQR 5-14; P < 0.001) for AFC. When stratified into two age groups the association between a lower AFC and endometriosis remained significant for both age groups whereas the association between a lower AMH and endometriosis was significant only for the group of women aged 35 years oor older. CONCLUSION Our study highlights a detrimental effect by endometriosis and an age enhancement effect of endometriosis on ovarian reserve.

Fertility Preservation in Endometriosis: Does Patient Symptomatology Affect the Extent of the Ovarian Response? Reprod Sci 2023:10.1007/s43032-023-01180-5.

Abstract
This study is to identify factors and patient symptomatology affecting ovarian response in women with endometriosis who seek fertility preservation. An observational cross-sectional study was conducted from July 2017 to May 2020 at a tertiary university-affiliated medical center. We included patients who were treated in the endometriosis clinic and underwent fertility preservation. Patients completed an online questionnaire that was cross-referenced with electronic charts. An analysis related to patient data and fertility preservation cycles and a mediation analysis were performed. The mean patient age at time of fertility preservation was 35.2 (± 4.9) years. The mean accumulated number of oocytes vitrified per patient was 16.7 (± 12.1) oocytes. The correlation coefficient assessed between the number of oocytes vitrified per cycle and AMH was significantly positive at +0.472, p = 0.006. The examined reported symptoms were lethargy, chronic pelvic pain, dyschezia, dyspareunia, bowel-associated symptoms, and urinary tract symptoms. The number of oocytes vitrified correlated with the number of reported symptoms and clinical characteristics at - 0.497, p = 0.0001, and - 0.442, p = 0.0001, respectively. In a mediation analysis, the potential causality of surgical intervention in the relationship between the number of symptoms and ovarian response was - 0.300 (95% CI [0.15, 1.905], p = 0.05), and the calculated proportion of mediation was estimated to be 17%. We observed a significant negative association between the number of clinical symptoms and the quantity of vitrified oocytes. This relationship was only partly associated with prior surgical intervention. AMH was found to have the highest correlation with treatment success in patients with endometriosis undergoing fertility preservation.

Abstract
Endometriotic ovarian cysts are one of the more common gynecological disorders found in reproductive-aged and infertile women. The aim of this review is to summarise information regarding the effect of surgical treatment of endometrioma on ovarian reserve. In women with endometrioma ovarian reserve is decreased compared to similarly aged healthy women and surgical management techniques cause an additional reduction. Evidence suggests that laparoscopic ovarian cystectomy via stripping is the preferable surgical technique for management of endometrioma, compared with excisional/ablative techniques, in the fields of pain improvement, spontaneous pregnancy rates, and ovarian cyst recurrences. Ablation techniques, combined technique and three-step approach demonstrate a less decline in anti-Müllerian hormone postoperatively. A successful operation involves not only removal of ovarian pathology, but also maintenance of ovarian function and future reproductive potential. Patients should be counselled about the risks of surgery and the management plan should be individualised to patient's symptoms and reproductive goals.

Abstract
Endometrioma is known to reduce the ovarian reserve and the extent of the decrease is more severe when ovarian surgery is performed. Therefore, to prevent this decline in fertility, patients with endometrioma are considered candidates for preoperative fertility preservation (FP). In this study, we evaluate the efficacy of FP in women with endometrioma before planned ovarian surgery. A total of 95 cycles in 62 patients with endometrioma, undergoing controlled ovarian stimulation (COS) for FP using a gonadotropin-releasing hormone (GnRH) antagonist protocol before an expected ovarian surgery, were enrolled retrospectively. COS outcomes were compared according to endometrioma laterality. Additionally, first COS cycle outcomes in patients with endometrioma were compared with those in infertile patients, or in patients with a benign ovarian cyst using propensity score matching. When multiple COS cycles were performed, the results of cumulative cycles were analyzed. Embryo quality was worse in the bilateral endometrioma group. Compared with the infertile patient group, the patients with endometrioma had significantly lower Anti-Müllerian Hormone (AMH) and fewer numbers of oocytes retrieved (median, 3.3 vs. 1.2, p<0.001; 7.0 vs. 4.0, p=0.009, respectively). Compared with mature oocytes in infertile patients or patients with a benign cyst, mature oocytes were fewer in patients with endometrioma, but this was not statistically significant (median, 4.0 vs. 3.0, p=0.085; 5.5 vs. 3.0, p=0.052, respectively). The median value of the cumulative number of cryopreserved oocytes or embryos was 14.5 up to the fourth cycle compared to 3 up to the first cycle, with cumulative effect. Women with endometrioma should be counseled for FP before planned ovarian cystectomy. The number of cryopreserved oocytes or embryos can be increased by repeated cycles.

Abstract
Endometriosis affects a great proportion of women during their reproductive years and may impair female fertility in several ways. Ovarian endometrioma (OE) is the most frequent phenotype and growing evidence suggest an endometrioma-mediated damage to the ovary, ovarian reserve and oocyte quality. Traditionally, surgery has been the first-line treatment in cases of OE. Great advances in assisted reproduction and fertility preservation techniques opened new possibilities towards a more conservative approach. Herein we discuss multiple mechanisms responsible for the deterioration of the reproductive capacity in cases of OE as well as the pros and cons of different treatment options. The management of endometrioma-related subfertility remains controversial and it will depend on patient's intentions and priorities. In the "internet era" patients tend to be hyper-informed and more participative, but they are often misguided and misinformed. Thus, doctors should be able to convert these individuals into well-informed patients in order to facilitate the process of shared decision making, which is extremely relevant in the context of OEs.

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
Endometriosis, despite only affecting 10-15% of women of fertile age, is still an enigmatic disease. Recent developments in assisted reproductive technology have contributed to a better understanding of where and how endometriosis could compromise fertility. In this mini-review we will show how the main point of damage in endometriosis is quantitative impairment of the ovaries, if the "less is more" mantra should be applied when considering ovarian surgery, and when fertility preservation prior to ovarian surgery could be considered. Endometrial receptivity, however, does not seem to be affected.

Abstract
Oocyte vitrification is an attractive and efficient option in the long-term management of endometriosis patients. Which women would benefit from banked oocytes when pregnancy is attempted, and whether oocyte vitrification should be carried out before or after the surgical management of endometriosis, is still debated. On the basis of recent data, and in the absence of cost-effective modelling, a personalized strategy should assess crucial variables, such as type of surgery, effect on oocyte yield and the huge heterogeneity of the clinical scenarios possibly requiring surgery. Research into a more tailored approach to maximize the result of each available intervention, e.g. hormones, surgery, assisted reproductive technology or their combination to prevent infertility and reduce the actual burden of personal and societal cost of the disease, is recommended.

Abstract
AIM Endometriosis, one of the most common gynecological disorder, is a challenging disease observed in 20 %-40 % of subfertile women. Endometriomas affect 17-44 % of women with endometriosis. Because endometrioma has detrimental effects on fertility, many of these women need Assisted Reproductive Technology (ART) to conceive. In this study, we aimed to investigate the effects of endometrioma presence and impact of bilaterality over In Vitro Fertilization (IVF) and Intracytoplasmic Sperm Injection (ICSI) outcomes. METHOD The study was designed retrospectively. A total of 159 women enrolled in IVF / ICSI cycles were included. Patients were divided into two groups as Endometrioma group (n: 73) and control group (n:86). In Endometrioma group, subgroup analysis was performed according to whether endometrioma was unilateral or bilateral. Demographic characters, clinical and laboratory parameters were recorded. SPSS was used for analysis. RESULTS In endometrioma group, although basal FSH levels was higher than control group, it was within normal limits, while estradiol levels was lower (p < 0.001, p 0.042, respectively). Antral follicle count (AFC), dominant follicle number, total oocyte count, MII oocyte numbers were found to be significantly lower, whereas numbers of embryos achieved, clinical pregnancy rates (PR) and live birth rates (LBR) were found to be similar.There were no statistically significant differences in terms of Antimullerian Hormon (AMH) levels, oocyte and embryo quality, the numbers of embryos achieved, PR and LBR between unilateral and bilateral endometrioma groups. CONCLUSION This study shows that presence of endometrioma negatively effects fertility parameters albeit no significant effect over embryo quality, PR and LBR whereas bilaterality doesn't have any influence over any fertility parameters and PR.

Abstract
Infertility affects 30% to 50% of women with endometriosis. Women with endometriosis are at risk of decreased ovarian reserve, both because of the pathophysiology of the disease and iatrogenic injury resulting from surgical intervention. Fertility preservation must occur at multiple levels, including careful selection of surgical candidates, avoidance of repeat procedures, and meticulous surgical technique. Fertility preservation with oocyte or ovarian tissue cryopreservation may be considered on an individual basis for women with endometriosis, particularly those at risk of bilateral ovarian injury, such as women with bilateral endometriomas.

Abstract
Background Laparoscopic cystectomy is currently considered the gold standard for the treatment of ovarian endometrioma, resulting in an improvement in symptoms, a lower recurrence rate, and a higher pregnancy rate among infertile patients. However, this treatment is not free from risk, since it is associated with a reduction in ovarian reserve. There is still controversy in the literature regarding whether the cause of the reduction in ovarian reserve is due to damage caused by the coagulation energy during hemostasis or whether the procedure itself is the cause of the damage irrespective of the hemostatic method used. The aim of this study is to compare the effects of different hemostatic methods on the ovarian function of women subjected to laparoscopic surgery for ovarian endometrioma. Methods An open-label randomized clinical trial to be conducted at the Lauro Wanderley University Hospital between December 2017 and August 2020. Eighty-four patients will be randomly allocated to three groups according to the hemostatic technique used during laparoscopic surgery for ovarian endometrioma: bipolar coagulation; laparoscopic suture; and hemostatic matrix. Ovarian function will be assessed by serum anti-Müllerian hormone measurement and by performing an antral follicle count using ultrasound before surgery and one, three, and six months after surgery. The internal review board of the Medical Sciences Center, Federal University of Paraíba approved the study protocol under reference CAAE 71621717.9.0000.8069. Discussion Bearing in mind the need for more randomized clinical trials to clarify this issue, we hope to contribute with data that will determine whether there is any difference between hemostatic methods despite the rational use of bipolar energy or whether the procedure itself explains the ovarian damage irrespective of the hemostatic technique used. Trial registration ClinicalTrials.gov, NTC03430609. Registered on XX.10/31/2017. ISRCTN Registry, ISRCTN11469394. Registered on XX.17/12/2017. Unique Protocol ID: U1111–1203-2508.

Abstract
OBJECTIVE To investigate temporary or long-term changes of AMH after laparoscopic endometrioma cystectomy and its dependency on characteristics of endometriomas. METHODS One hundred and seventy-one women, open-labeled prospective study; five groups divided according age ≤/> 35, uni-/bilateral, cyst ≤/> 7 cm, coagulation/suture surgery, stage III/IV; between- and within-group analyses after 1, 3, 6, and 12 months. RESULTS After 12 months, compared to pretreament, AMH decreased significantly for patients with bilateral cysts, cyst size >7 cm and endometriosis stage IV. In the between-group analysis all comparisons were significant, with exception of the surgery type. However, this was different performing the multiple linear regression analysis suggesting lower postoperative decrease using suturing technique. This analysis also showed higher age at pretreatment and bilateral cysts as risk factor for AMH decline. CONCLUSIONS Effects of endometrioma cystectomy on AMH are dependent on characteristics of the endometrioma, showing long-term a decrease in patients with larger, bilateral cysts and in stage IV endometriosis, but only short-time decrease in smaller, unilateral cysts and stage III which sometimes also can fully recover in AMH production within one year. In our study suture compared to coagulation surgery was protective, i.e. may lead to lower postoperative AMH decline.

Abstract
OBJECTIVE To evaluate if the presence of endometriomas impacts on the ovarian reserve as evaluated with antimüllerian hormone (AMH). DESIGN Systematic review and meta-analysis. SETTING Not applicable. PATIENT(S) Patients with unoperated endometriomas versus controls without endometriomas. INTERVENTION(S) Electronic databases searched up to June 2017 to identify articles evaluating AMH levels in patients with unoperated endometriomas versus controls without endometriomas. MAIN OUTCOME MEASURE(S) The primary analysis was aimed at evaluation of AMH levels (mean and SD) in patients with and without endometriomas. Secondary analyses were aimed at evaluating AMH levels in patients with ovarian endometriomas compared to patients with either non-endometriosis benign ovarian cysts or healthy ovaries. RESULT(S) Of the 39 studies evaluated in detail, 17 were included, for a total of 968 patients with endometriomas and 1874 without endometriomas. AMH was significantly lower in patients with unoperated endometriomas compared to patients with no endometriomas (mean difference -0.84, with 95% confidence interval [CI] -1.16 to -0.52). At secondary analyses, AMH in patients with endometriomas was significantly lower both versus non-endometriosis benign ovarian cysts (mean difference -0.85, 95% CI -1.37 to -0.32, and versus women with healthy ovaries (mean difference -0.61, 95% CI -0.99 to -0.24). CONCLUSION(S) Ovarian reserve evaluated with AMH is reduced in patients with ovarian endometriomas compared both to patients with other benign ovarian cysts, and to patients with healthy ovaries.

Abstract
PURPOSE OF REVIEW Surgery has traditionally been the primary treatment option for endometriosis-related infertility of any phenotype. However, advances and refinements of assisted reproductive technologies (ART) permit a more conservative approach in many scenarios. This review summarizes the latest findings in the field of reproductive medicine, which have supported a paradigm shift towards more conservative management of ovarian endometrioma. RECENT FINDINGS The presence of ovarian endometrioma per se is likely to impair ovarian reserve and alter ovarian functional anatomy. Conventional laparoscopic surgery is associated with significant risk of additional damage, and less invasive treatment approaches require further evaluation. With regard to infertile women with ovarian endometrioma who are scheduled for ART treatment, current data indicate that prior surgical intervention does not improve ART outcomes, and that controlled ovarian hyperstimulation (COH) does not affect quality of life or pain symptoms. SUMMARY Reproductive medicine physicians frequently encounter patients with ovarian endometrioma. The current evidence does not support the postponement of infertility treatment in favour of surgery, except in cases with severe symptoms or to improve follicle accessibility. Although these patients may exhibit diminished ovarian response to COH, their endometrial receptivity, aneuploidy rates, and fertility outcomes are similar to healthy controls. Surgery for ovarian endometrioma provides no benefits in ART treatments.

Abstract
Formation of the ovarian endometrioma consists of implantation, invagination of the ovarian cortex, and adhesion formation. Progression is characterized by repeated injury and repair with degenerative changes. Already with a partially deprived ovarian reserve, resulting from the disease, surgical treatment carries a potential risk of further follicular deprivation. Surgery should therefore be performed with microsurgical precision by experienced hands. Early treatment can possibly prevent further progression. The adverse impact on ovarian reserve of the ablative approach has to be balanced against a lower recurrence rate of a cystectomy. Adapted surgical approaches like a two-step approach or a combination of excisional and ablative surgery has to be considered in case of a large endometrioma. Further studies on the possibility and advantages of sclerotherapy are warranted. Fertility preservation by cryopreservation of ovarian cortex should be part of the informed consent with the patient.

Abstract
Endometriosis is an estrogen-dependent inflammatory disease that affects up to 10% of women of reproductive age and accounts for up to 50% of female infertility cases. It has been highly associated with poorer outcomes of assisted reproductive technology (ART), including decreased oocyte retrieval, lower implantation, and pregnancy rates. A better understanding of the pathogenesis of endometriosis-associated infertility is crucial for improving infertility treatment outcomes. Current theories regarding how endometriosis reduces fertility include anatomical distortion, ovulatory dysfunction, and niche inflammation-associated peritoneal or implantation defects. This review will survey the latest evidence on the role of inflammatory niche in the peritoneal cavity, ovaries, and uterus of endometriosis patients. Nonhormone treatment strategies that target these inflammation processes are also included. Furthermore, mesenchymal stem cell-based therapies are highlighted for potential endometriosis treatment because of their immunomodulatory effects and tropism toward inflamed lesion foci. Potential applications of stem cell therapy in treatment of endometriosis-associated infertility in particular for safety and efficacy are discussed.
