OBJECTIVE: Laparoscopic cystectomy for ovarian endometriomas and benign ovarian cysts is often conducted through hemostatic methods, with bipolar electrocoagulation as a common approach. This study evaluated the impact of electrocoagulation, primarily through bipolar energy, versus nonthermal hemostatic methods on ovarian reserve in patients undergoing laparoscopic cystectomy for ovarian endometriomas and benign ovarian cysts.
METHODS: A systematic review with meta-analysis was conducted by searching the Cochrane Library, PubMed, EMBASE, and Web of Science databases. Randomized controlled trials (RCTs) comparing the impact of nonthermal hemostatic methods and electrocoagulation on the ovarian reserve during laparoscopic cystectomy were included. The Cochrane Risk of Bias Tool for Randomized Controlled Trials (ROB 2.0) was utilized to assess the quality of the included studies. The meta-analysis included 13 RCTs involving 1043 patients. Postoperative serum anti-Müllerian hormone (AMH) levels and antral follicle counts (AFCs) were analyzed using Review Manager ver. 5.4.
RESULTS: Compared with the bipolar group, patients with endometriomas in the nonthermal hemostatic group exhibited significantly higher postoperative AMH levels at 1, 3, 6, and 12 months. Conversely, no significant differences in AMH levels were observed in patients with benign ovarian cysts. Similarly, AFCs showed no significant differences, except for lower postoperative AFCs in patients with endometrioma in the electrocoagulation group.
CONCLUSIONS: Nonthermal hemostatic methods are associated with more effective preservation of the ovarian reserve compared with bipolar electrocoagulation in laparoscopic cystectomy for ovarian endometriomas. However, no significant impact of bipolar electrocoagulation on the ovarian reserve was observed in patients with benign ovarian cysts.

DNA damage is a key factor affecting gametogenesis and embryo development. The integrity and stability of DNA are fundamental to a woman\'s successful conception, embryonic development, pregnancy and the production of healthy offspring. Aging, reactive oxygen species, radiation therapy, and chemotherapy often induce oocyte DNA damage, diminished ovarian reserve, and infertility in women. With the increase of infertility population, there is an increasing need to study the relationship between infertility related diseases and DNA damage and repair. Researchers have tried various methods to reduce DNA damage in oocytes and enhance their DNA repair capabilities in an attempt to protect oocytes. In this review, we summarize recent advances in the DNA damage response mechanisms in infertility diseases such as PCOS, endometriosis, diminished ovarian reserve and hydrosalpinx, which has important implications for fertility preservation.

OBJECTIVE: To compare the ovarian reserve and the results of infertility treatment, as well as to investigate the relapse rate in the first year after the assisted reproductive technology (ART) cycle in patients with multiple sclerosis (MS) referred to Royan Institute.
METHODS: This retrospective study was carried out to evaluate all women diagnosed with MS and referred to Royan Institute for assessment and treatment of possible infertility between 2011 and 2022. The control group consisted of randomly selected healthy women with tubal factor infertility who were referred for treatment during the same time period and matched in terms of age. A comparison was made between groups in terms of ovarian reserve and infertility treatment outcomes. Additionally, patients with MS who met the criteria were monitored via telephone to evaluate the symptoms, disability and relapse rate both pre- and post-ART.
RESULTS: Over the course of a decade, the database documented a total of 60 cases diagnosed with MS. Upon examination of the records, it was found that in 27 patients only admission was done without any hormonal assessment or infertility treatment cycle and 5 patients proceeded with the intrauterine insemination cycle. Eventually, 28 women with MS underwent the ART cycle and all of them were treated with interferon beta, glatiramer acetate, or some oral disease modifying therapies. No statistically significant difference in terms of the basal levels of luteinizing hormone, follicle-stimulating hormone and anti-Müllerian hormone was found between the MS and control groups (P > 0.05). Two groups were comparable in terms of menstrual status. The study revealed that both groups exhibited similarities in terms of the controlled ovarian stimulation protocol and duration, the dosage of gonadotropin administered, as well as the ovarian response type, clinical pregnancy rate, and live birth rate (P > 0.05). After follow up, only 2 patients (9.5%) reported relapse of symptoms within one year after ART.
CONCLUSIONS: The ovarian reserve and ovarian stimulation cycle and pregnancy outcomes following the ART cycle in MS patients were similar to the age-matched control group. The relapse rate of multiple sclerosis did not show a significant increase within a year following the ART cycle.

UNASSIGNED: To quantitatively evaluate the effect of coenzyme Q10 (CoQ10) pretreatment on outcomes of IVF or ICSI in women with diminished ovarian reserve (DOR) based on the existing randomized controlled trials (RCTs).
UNASSIGNED: Nine databases were comprehensively searched from database inception to November 01, 2023, to identify eligible RCTs. Reproductive outcomes of interest consisted of three primary outcomes and six secondary outcomes. The sensitivity analysis was adopted to verify the robustness of pooled results.
UNASSIGNED: There were six RCTs in total, which collectively involved 1529 participants with DOR receiving infertility treatment with IVF/ICSI. The review of available evidence suggested that CoQ10 pretreatment was significantly correlated with elevated clinical pregnancy rate (OR = 1.84, 95%CI [1.33, 2.53], p = 0.0002), number of optimal embryos (OR = 0.59, 95%CI [0.21, 0.96], p = 0.002), number of oocytes retrieved (MD = 1.30, 95%CI [1.21, 1.40], p < 0.00001), and E2 levels on the day of hCG (SMD = 0.37, 95%CI [0.07, 0.66], p = 0.01), along with a reduction in cycle cancellation rate (OR = 0.60, 95%CI [0.44, 0.83], p = 0.002), miscarriage rate (OR = 0.38, 95%CI [0.15, 0.98], p = 0.05), total days of Gn applied (MD = -0.89, 95%CI [-1.37, -0.41], p = 0.0003), and total dose of Gn used (MD = -330.44, 95%CI [-373.93, -286.96], p < 0.00001). The sensitivity analysis indicated that our pooled results were robust.
UNASSIGNED: These findings suggested that CoQ10 pretreatment is an effective intervention in improving IVF/ICSI outcomes for women with DOR. Still, this meta-analysis included relatively limited sample sizes with poor descriptions of their methodologies. Rigorously conducted trials are needed in the future.

UNASSIGNED: In women, exposure to endocrine disrupting chemicals might accelerate the depletion of the ovarian reserve and might be associated with accelerative reproductive aging and fertility. We examined the longitudinal associations of exposure to bisphenols and phthalates with anti-Müllerian hormone concentrations.
UNASSIGNED: Pregnant women of 18 years or older that resided in Rotterdam between 2002 and 2006 were eligible for participation in this longitudinal prospective cohort study. We measured urinary bisphenol and phthalate concentration at three time-points in pregnancy among 1405 women, of whom 1322 women had serum Anti-Müllerian Hormone (AMH) measurements 6 and/or 9 years postpartum. We performed linear regression models to assess the association of urinary bisphenol and phthalate metabolites with AMH after 6 and 9 years, and linear mixed-effect model to assess the association with AMH over time. Models were adjusted for sociodemographic and lifestyle factors.
UNASSIGNED: In our multivariable linear regression models we observed associations of higher urinary pregnancy-averaged mono-isobutyl phthalate (mIBP), mono-(2-ethyl-5-oxohexyl) phthalate (mEOHP), and monobenzyl phthalate (mBzBP) with lower serum AMH after both 6 and 9 years. However, these associations did not remain after adjustment for multiple testing. No significant associations of bisphenol A with AMH were present in our study sample. In our linear mixed-effects models, higher mIBP, mono-(2-ethyl-5-hydroxyhexyl) phthalate (mEHHP), mEOHP, and mBzBP were associated with lower overall AMH levels (differences -0.07 (95% CI -0.13, -0.02), -0.09 (-0.15, -0.02), -0.08 (95% CI -0.14, -0.02), and -0.08 (-0.13, -0.03) μg/L per doubling in mIBP, mEHHP, mEOHP, and mBzBP respectively) (all False Discovery Rate adjusted p-values < 0.05).
UNASSIGNED: We identify decreases in indices of ovarian reserve in relationship to prenatal phthalate exposures. Studies are needed replicating our results among large multi-ethnic non-pregnant populations and assessing transgenerational effects of exposure on ovarian reserve.

OBJECTIVE: To explore the possible regulatory mechanism of microRNA (miRNA) in moxibustion treatment for decreased ovarian reserve (DOR).
METHODS: The DOR model was constructed by intragastrical Tripterygium glycoside suspension administration, and moxibustion therapy was simultaneously given. The morphological ovarian changes were observed by hematoxylin and eosin staining. The miRNA expression profile was detected by RNA sequencing, and bioinformatics analysis was performed. Cytoscape software 3.6.1 was used to establish a regulatory network and differentially expressed miRNAs were verified by reverse transcription quantitative polymerase chain reaction (RT-qPCR).
RESULTS: Decreased number of mature follicles, increased atresia follicles, and abnormal granulosa cell morphology were observed in the model group compared with the control group. The moxibustion group demonstrated increased mature follicles, decreased atretic follicles, and significantly decreased abnormal morphology of granulosa cells compared with the model group. Additionally, RNA sequencing results manifested significantly up-regulated miRNA expressions (miR-92b-3p, miR-26-5p_R + 1_1ss10TC, miR-206-3p, miR-9993b-3p_1ss6GA, miR-7857-3p_R-1, miR-219a-2-3p_1ss10GC, miR-3968-p5_1ss10AT, and PC-5p-6478_1795) and down-regulated miR-664-2-5p_R + 1 in the model group, compared with the control group, and the moxibustion group reversed abnormal disorder levels of these miRNAs. Moreover, these differentially expressed miRNAs were mainly involved in the phosphatidylinositol-3-kinase / protein kinase B signaling pathway and nuclear factor erythropoietin-2-related factor 2 / heme oxygenase 1 signaling pathway. Finally, network and RT-qPCR verification revealed miR-9993b-3p_1ss6GA as the most critical miRNA.
CONCLUSIONS: This experiment proved the effectiveness of moxibustion in improving the ovarian reserve of rats by regulating miRNA expression, especially miR-9993b-3p_1ss6GA.

The COVID-19 pandemic caused by SARS-CoV-2 has presented numerous health challenges, including long-term COVID, which affects female reproductive health. This review consolidates the current research on the impact of SARS-CoV-2 on the menstrual cycle, ovarian function, fertility, and overall gynecological health. This study emphasizes the role of angiotensin-converting enzyme receptors in viral entry and the subsequent tissue-specific pathological effects. It also explores the potential influence of long COVID on hormonal balance and immune responses, contributing to menstrual irregularities and impaired ovarian function. The findings indicate a higher prevalence of long-term COVID-19 among women, highlighting the substantial implications for reproductive health and the need for sex-sensitive longitudinal studies. Enhanced surveillance and targeted research are essential to develop effective interventions that prioritize women\'s reproductive well-being following SARS-CoV-2 infection. This review advocates for a sex-informed approach to ongoing COVID-19 research and healthcare strategies, aiming to provide up-to-date and pertinent data for healthcare providers and the general public, ultimately improving outcomes for females affected by long COVID.

Reproductive aging not only affects the fertility and physical and mental health of women but also accelerates the aging process of other organs. There is an urgent need newfor novel mechanisms, targets, and drugs to break the vicious cycle of mitochondrial dysfunction, redox imbalance, and germ cell apoptosis associated with ovarian aging. Autophagy, recognized as a longevity mechanism, has recently become a focal point in anti-aging research. Although mitophagy is a type of autophagy, its role and regulatory mechanisms in ovarian aging, particularly in age-related ovarian function decline, remain unclear. Nerve growth factor inducible gene B (Nur77) is an early response gene that can be stimulated by oxidative stress, DNA damage, metabolism, and inflammation. Recent evidence recommends that decreased expression of Nur77 is associated with age-related myocardial fibrosis, renal dysfunction, and Parkinson\'s disease; however, its association with ovarian aging has not been studied yet. We herein identified Nur77 as a regulator of germ cell senescence, apoptosis, and mitophagy and found that overexpression of Nur77 can activate mitophagy, improve oxidative stress, reduce apoptosis, and ultimately enhance ovarian reserve in aged mice ovaries. Furthermore, we discovered an association between Nur77 and the AKT pathway through String and molecular docking analyses. Experimental confirmation revealed that the AKT/mTOR signaling pathway is involved in the regulation of Nur77 in ovarian function. In conclusion, our results suggest Nur77 as a promising target for preventing and treating ovarian function decline related to reproductive aging.

Diminished ovarian reserve (DOR) is associated with reduced fertility and poor reproductive outcomes. The association between dietary patterns and DOR was not well studied. The purpose of this study was to evaluate the relationship between adhering to the healthy eating index (HEI-2015) and the risk of DOR. In this case-control study, 370 Iranian women (120 with DOR and 250 age- and BMI-matched controls) were examined. A reliable semi-quantitative food frequency questionnaire was used to collect diet-related data. We analyzed the HEI-2015 and their dietary intake data to determine major dietary patterns. The multivariable logistic regression was used in order to analyze the association between HEI-2015 and risk of DOR. We found no significant association between HEI-2015 score and risk of DOR in the unadjusted model (OR 0.78; 95%CI 0.59, 1.03). After controlling for physical activity and energy intake, we observed that women in the highest quartile of the HEI-2015 score had 31% decreased odds of DOR (OR 0.69; 95%CI 0.46, 0.93). This association remained significant even after adjusting for all potential confounders. Overall, increased adherence to HEI may lead to a significant reduction in the odds ratio of DOR. Clinical trials and prospective studies are needed to confirm this association.

OBJECTIVE: This position statement by the Italian Society of Fertility and Sterility and Reproductive Medicine (SIFES-MR) aims to establish an optimal framework for fertility preservation outside the standard before oncological therapies. Key topics include the role of fertility units in comprehensive fertility assessment, factors impacting ovarian potential, available preservation methods, and appropriate criteria for offering such interventions.
METHODS: The SIFES-MR writing group comprises Italian reproductive physicians, embryologists, and scientists. The consensus emerged after a six-month period of meetings, including extensive literature review, dialogue among authors and input from society members. Final approval was granted by the SIFES-MR governing council.
RESULTS: Fertility counselling transitions from urgent to long-term care, emphasizing family planning. Age, along with ovarian reserve markers, is the primary predictor of female fertility. Various factors, including gynecological conditions, autoimmune disorders, and prior gonadotoxic therapies, may impact ovarian reserve. Oocyte cryopreservation should be the preferred method. Women 30-34 years old and 35-39 years old, without known pathologies impacting the ovarian reserve, should cryopreserve at least 12-13 and 15-20 oocytes to achieve the same chance of a spontaneous live birth they would have if they tried to conceive at the age of cryopreservation (63% and 52%, respectively in the two age groups).
CONCLUSIONS: Optimal fertility counselling necessitates a long-term approach, that nurtures an understanding of fertility, facilitates timely evaluation of factors that may affect fertility, and explores fertility preservation choices at opportune intervals.
