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.

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: The aim of this article was to discuss all the factors affecting the age at menopause and their correlation with ovarian reserve.
UNASSIGNED: A narrative review of original articles was performed using PubMed until December 2023. The following keywords were used to generate the list of citations: \'menopause\', \'ovarian reserve\' \'oocytes quality and quantity\', \'ovarian ageing\'.
UNASSIGNED: Menopause is the final step in the process of ovarian ageing and is influenced by the oocyte pool at birth. Conditions that accelerate follicle depletion during the reproductive lifespan lead to premature ovarian insufficiency (POI) and premature ovarian failure (POF), while a higher ovarian reserve is associated with a delayed time to menopause. Reproductive history, sociodemographic, lifestyle and iatrogenic factors may impact ovarian reserve and the age at menopause.
UNASSIGNED: Some factors affecting the age at menopause are modifiable and the risks of early menopause may be preventable. We hypothesise that by addressing these modifiable factors we may also preserve ovarian reserve. However, further interventional studies are needed to evaluate the effects of the described strategies on ovarian reserve.
The age of menopause is determined by the process of follicle depletion, which leads to a decrease in the quantity and quality of oocytes. Various factors such as demographics, menstrual patterns, reproductive history, family history, genetics, and lifestyle choices appear to influence the age at which natural menopause occurs. Some of these factors can be modified. Considering the relationship between ovarian reserve and the age of natural menopause, is it possible to intervene on these modifiable factors to preserve ovarian reserve?

Reproductive impairment is the most prevalent yet most ignored complication of diabetes mellitus. In diabetes, the problem associated with reproductive health is comprehensive in both males and females. Diabetic females have problems like delayed menarche, irregular menstrual cycle, subfertility, complications in pregnancy and early menopause. This may decrease reproductive age in diabetic females as the menarche is delayed and menopause is early in them. Like diabetic males, diabetic females also have the negative effect of oxidative stress on the reproductive system. This may lead to dysfunction of the ovary. It affects the physiological cycle like the ovary\'s maturation, embryo development and pregnancy. These complications also affect the offspring, and they may also become diabetic. This review aims to concentrate on the effect of diabetes on the reproductive system of females and the impairment caused by it. We will also discuss in detail the role of the hypothalamus-pituitary ovary axis, diabetes impact on different reproductive phases of females, and the sexual disorders that occur in them.

We aimed to conduct a systematic review of the data in the literature on ovarian reserve and ovarian hormone following laparoscopic ovarian drilling (LOD). The PubMed, ScienceDirect, and ProQuest databases were comprehensively searched using a combination of keywords such as \"ovarian reserve\", \"laparoscopic ovarian drilling\", \"luteinizing hormone\", \"follicle-stimulating hormone\", \"inhibin\", \"LH/FSH ratio\", \"ovulation\", and \"testosterone\". All studies involving females of reproductive age who were officially diagnosed with polycystic ovarian syndrome (PCOS) and had undergone LOD with reported data concerning at least one of the following parameters were considered for inclusion: ovarian reserve, anti-Mullerian hormone (AMH), inhibin, follicle-stimulating hormone (FSH), luteinizing hormone (LH), LH/FSH ratio, and testosterone. All the included studies were evaluated by the GRADE scale for bias and their findings were synthesized by four independent coauthors. A total of 38 studies involving 3118 female patients were included. Based on our findings, a significant number of participants experienced spontaneous ovulation along with a significant decrease in ovarian reserve, and a significant decrease in AMH, LH, and testosterone, with no significant changes in FSH and inhibin B. With the end goal of LOD being to improve fertility and pregnancy rates among females with PCOS, it is important to look at the first few steps that enable this. As expected, there was a significant improvement in ovulation while the ovarian reserve decreased. Along with the decrease in ovarian reserve, there was a significant normalization in AMH, LH, and testosterone levels. LOD may exert its main effects through the manipulation of the ovarian reserves.

Background: In the last decade, increasing evidence has suggested that high-grade serous ovarian cancers may have their origin in the fallopian tube rather than the ovary. This emerging theory presents an opportunity to prevent epithelial ovarian cancer by incorporating prophylactic bilateral salpingectomy into all surgical procedures for average-risk women. The aim of this review is to investigate the hypothesis that bilateral salpingectomy (BS) may have a negative impact on ovarian reserve, not only following hysterectomy for benign uterine pathologies but also when performed during cesarean sections as a method of sterilization or as a treatment for hydrosalpinx in Assisted Reproductive Technology interventions. Methods: PubMed, Medline, Google Scholar, and Cochrane were searched for original studies, meta-analyses, and opinion articles published between 2014 and 2024. Results: Out of 114 records from the database search, after the removal of duplicates, 102 articles were considered relevant for the current study. Conclusions: Performing opportunistic salpingectomy seems to have no adverse impact on ovarian function in the short term. However, because there is an existing risk of damaging ovarian blood supply during salpingectomy, there are concerns about potential long-term adverse effects on the ovarian reserve, which need further investigation.

BACKGROUND: Evidence supports the benefits of hydroxyurea (HU) in adults with sickle cell disease (SCD), but reservations remain due to long-term concerns of fertility. Retrospective analysis of clinical records of SCD patients (haemoglobin SS genotype) have identified gender-related differences in disease progression. This could inform risk stratification during SCD at diagnosis with the possibility to guide therapeutic decisions.
METHODS: This systemic review and meta-analysis evaluated fertility parameters in both children (aged ≥ 6 years) and adults with SCD receiving HU therapy. Studies were sourced from PubMed and EMBASE from inception to July 2023. A total of 160 potentially relevant articles were identified.
RESULTS: Four studies were included that evaluated the effects of HU on sperm parameters in males. A further 4 studies assessed anti-mullerian hormone (AMH) levels and ovarian reserves in females. Differences from baseline values were used to identify compromised fertility. Amongst males, HU treatment negatively impacted the concentration of spermatozoa (MD = -15.48 million/mL; 95% CI: [-20.69, -10.26]; p< 0.001), which continued following treatment cessation (MD = -20.09 million/mL; 95% CI: [-38.78, -1.40]; P = 0.04). HU treatment also led to lower total sperm counts (MD = -105.87 million; 95% CI: [-140.61, -71.13]; P< 0.001) which persisted after treatment (MD = -53.05 million; 95% CI: [-104.96, -1.14]; P = 0.05). Sperm volume, initial forward motility and morphology were unaffected by HU treatment. In females, HU treatment decreased the mean AMH levels 1.83 (95% CI [1.42, 2.56]. A total of 18.2.% patients treated with HU showed reduced ovarian reserves.
CONCLUSIONS: This systemic review and meta-analysis suggest that the use of HU for SCD impacts seminal fluid parameters in males and can diminish AMH levels and ovarian reserves in females.

Patients with haematologic malignancies represent one of the most common groups referred for fertility preservation before gonadotoxic oncological treatment. The aim of this systematic review and meta-analysis was to evaluate the effect of haematologic cancer on ovarian reserve and response to ovarian stimulation compared with healthy controls. A total of eight observative studies were included in the final quantitative analysis. Despite a younger age (mean difference -4.17, 95% CI -6.20 to -2.14; P < 0.0001), patients with haematologic malignancy had lower serum anti-Müllerian hormone levels compared with the control group (MD -1.04, 95% CI -1.80 to -0.29; P = 0.007). The marginally higher total recombinant FSH dose (MD 632.32, 95% CI -187.60 to 1452.24; P = 0.13) and significantly lower peak oestradiol serum level (MD -994.05, 95% CI -1962.09 to -26.02; P = 0.04) were demonstrated in the study group compared with the healthy controls. A similar number of retrieved oocytes were achieved in both groups (MD 0.20, 95% CI -0.80 to 1.20; P = 0.69). In conclusion, haematologic malignancies may detrimentally affect ovarian function manifesting in decreased AMH serum levels despite a younger age compared with healthy controls. This effect can be overcome by the application of relevant IVF protocols and stimulation doses to achieve an adequate oocyte yield.

BACKGROUND: It is still unclear whether Crohn\'s disease (CD) might be associated with diminished ovarian reserve (OvR) and factors influencing anti-Mullerian hormone (AMH) levels in CD are poorly known.
METHODS: We conducted a comprehensive literature search of multiple electronic databases from inception to June 2022 to identify all studies reporting AMH levels or factors associated with diminished OvR in patients with CD.
RESULTS: Of the 48 studies identified in our search, eight (including 418 patients with CD) were finally included. The mean difference (95% confidence interval [CI]) in the AMH level between pooled CD patients and controls was -0.56 (-1.14 to 0.03) (p = 0.06). A history of CD-related surgery was not associated with a lower OvR (odds ratio, OR [95% CI] 1.34, [0.66-2.7]; p = 0.4). While disease activity and perianal disease seems associated with a low OvR, disease location (L2 vs. L1, OR [95% CI] = 95% CI [0.47-7.4]; p = 0.4) and L3 vs. L1 (OR [95% CI] = 1.44 [0.67-3.12]; p = 0.3), CD medication, and disease behavior were not.
CONCLUSIONS: Our systematic review and meta-analysis did not identify a significantly low OvR in patients with CD. Contrary to CD-related surgery risk factor, active disease was associated lower AMH levels.
