Acupuncture and moxibustion for diminished ovarian reserve: A scoping review.

OBJECTIVE: Diminished ovarian reserve (DOR) refers to the decreased number and quality of oocytes in the ovary. Acupuncture and moxibustion has a certain effect on DOR; however, the number of studies and reports of research evidence are limited. This study aimed to conduct a scoping review of the clinical research status of acupuncture and moxibustion for treating patients with DOR. METHOD: PubMed, Cochrane Library, Excerpta Medica database, Allied and Complementary Medicine Database, Chinese Biological Medicine, China National Knowledge Infrastructure, VIP Database for Chinese Technical Periodicals, and Wanfang database were searched from January 2010 to May 2022 using keywords and medical subject heading terms. After applying the inclusion and exclusion criteria, relevant studies were selected. Structured tables and descriptive charts were made to visually express research features by using Excel, Original, IBM SPSS Model 18.0, Adobe Illustrator and other software packages. Report quality was evaluated for Cochrane bias using Review Manager 5.3. RESULTS: Overall, 851 studies were identified; of these, 90 met the inclusion criteria. The results extracted from these studies were classified into four categories: research characteristics, study type, acupuncture and moxibustion prescriptions, and efficacy observation. CONCLUSIONS: The quality assessment of acupuncture and moxibustion for DOR is not ideal. Therefore, standardisation and normalisation should be strengthened, and high-quality evidence is needed to further demonstrate the effectiveness of this approach. Due to heterogeneity in DOR diagnosis, the observation index should be updated with reference to the latest research to improve efficacy evaluation.

Clinical efficacy of acupuncture for diminished ovarian reserve: a systematic review and meta-analysis of randomized controlled trials.

Objective: To evaluate the clinical efficacy of acupuncture for the treatment of diminished ovarian reserve (DOR) based on the existing randomized controlled trials (RCTs). Methods: Nine databases from their inception to December 6th, 2022, were comprehensively searched to retrieve RCTs related to the clinical efficacy of acupuncture for the treatment of DOR. The outcomes of interest were sex hormones level and antral follicle count (AFC). Risk of Bias (RoB) was adopted to assess the quality of the included trials. Results: A total of 13 RCTs involving 787 patients were included in this meta-analysis. The review of available evidence revealed acupuncture produced a significant efficacy in decreasing follicle-stimulating hormone (FSH) levels (SMD = -1.07, 95%CI [-1.79, -0.36], p = 0.003), FSH/LH ratio (MD = -0.31, 95%CI [-0.54, -0.09], p = 0.006) and increasing anti-Müllerian hormone (AMH) levels (SMD = 0.25, 95%CI [-0.00, 0.49], p = 0.05), along with AFC (MD = 1.87, 95%CI [0.96, 2.79], p < 0.0001) compared to controls. Compared with electro-acupuncture treatment, manual acupuncture was superior in reducing FSH levels, FSH/LH ratio, and increasing AMH levels and AFC (p < 0.05). A notable association was also seen when acupuncture was combined with traditional Chinese medicine therapy for improving FSH levels, FSH/LH ratio, and AFC (p < 0.05). Besides, a high dose of acupuncture (≥10 acupoints) was more conducive to ameliorating FSH levels, FSH/LH ratio, and AFC (p < 0.05) than a low dose of acupuncture (<10 acupoints). Substantial heterogeneity existed among studies. Conclusion: Acupuncture may have significant clinical potential for patients with DOR in terms of improving sex hormones level and increasing AFC, although the evidence is drawn with high heterogeneity. This finding suggests that more rigorous trials conducted in diverse regions worldwide are necessary to identify the efficacy of acupuncture for patients diagnosed with DOR.

Investigation of the Mechanisms and Experimental Verification of Yulin Formula in the Treatment of Diminished Ovarian Reserve via Network Pharmacology.

Purpose: The aim of this study is to examine, using network pharmacology analysis and experimental validation, the pharmacological processes by which Yulin Formula (YLF) reduces cyclophosphamide-induced diminished ovarian reserve (DOR). Methods: First, information about the active components, associated targets, and related genes of YLF and DOR was gathered from open-access databases. The primary targets and pathways of YLF to reduce DOR were predicted using studies of functional enrichment from the Kyoto Encyclopedia of Genes and Genomes (KEGG), Gene Ontology (GO), and Protein-Protein Interaction (PPI) networks. Second, we built a cyclophosphamide-induced diminished ovarian reserve (DOR) rat model to verify the primary target proteins implicated in the predicted signaling pathway to explore the mechanism of improve ovarian function of YLF. Results: 98 targets met the targets of the 82 active ingredients in YLF and DOR after searching the intersection of the active ingredient targets and DOR targets. Fourteen targets, including AKT and Caspase-3 among others, were hub targets, according to the PPI network study. The PI3K/AKT pathway was revealed to be enriched by numerous targets by the GO and KEGG enrichment studies, and it was used as a target for in vivo validation. Animal studies showed that YLF administration not only reduced the number of atretic follicles, the proportion of TUNEL-positive ovarian cells, the rate of apoptosis of granulosa cells (GCs) and the proportion of abnormal mitochondria in DOR rats, but also reversed the high expression of Caspase-3, Caspase-9, BAX, cytochrome C, PI3K and P-AKT, improving the ovarian reserve in cyclophosphamide (CTX)-induced DOR rats. Conclusion: Our research results predicted the active ingredients and potential targets of YLF-interfering DOR by an integrated network pharmacology approach, and experimentally validated some key target proteins participated in the predicted signaling pathway. A more comprehensive understanding of the pharmacological mechanism of YLF for DOR treatment was obtained.

[Predictive factors of spontaneous pregnancies among women with diminished ovarian reserve patients treated with DHEA]. / Facteurs prédictifs de grossesse spontanée chez les femmes présentant une réserve ovarienne diminuée traitées par DHEA.

INTRODUCTION: Diminished ovarian reserve remains a challenge in the reproductive medicine field. Treatment options for these patients are limited and there is no consensus to make any recommendations. Regarding adjuvant supplements, DHEA could play a role in follicular recruitment and, therefore, may increase spontaneous pregnancy rate. MATERIALS AND METHODS: This study was a monocentric historical and observational cohort study carried out in the reproductive medicine department at the University Hospital, Femme-Mère-Enfant in Lyon. All women presenting with a diminished ovarian reserve treated with 75mg/day of DHEA were consecutively included. The main objective was to evaluate the spontaneous pregnancy rate. The secondary objectives were to identify predictive factors for pregnancy and the evaluation of treatment side effects. RESULTS: Four hundred and thirty-nine women were included. In all, 277 were analyzed, 59 had a spontaneous pregnancy (21.3%). The probability of being pregnant was respectively 13.2% (IC95 9-17.2%), 21.3% (IC95 15.1-27%) and 38.8% (IC95 29.3-48.4%) at 6, 12 and 24 months. Only 20.6% of patients complained of side effects. CONCLUSION: DHEA may improve spontaneous pregnancies in women with diminished ovarian reserve without any stimulation.

MicroRNA profiling reveals effects of Erzhi Tiangui granules on kidney deficiency diminished ovarian reserve: A randomized trial.

BACKGROUND: Diminished ovarian reserve (DOR) is a danger signal of reduced fertility. The clinical incidence is increasing yearly, exhibiting a gradual low-age trend. Traditional Chinese medicine theory suggests that kidney deficiency is the basic pathogenesis. Erzhi Tiangui granules (ETG), a kidney-tonifying prescription, have been clinically shown to improve ovarian reserve function. The purpose of this study was to investigate the microRNA (miRNA) markers of kidney deficiency DOR and the potential mechanism of ETG on in vitro fertilization outcomes in DOR patients. METHODS: Experiment 1: Granulosa cells from 5 normal ovarian reserves and 5 kidney deficiency DOR patients were subjected to miRNA sequencing. Experiment 2: Eighty DOR patients were randomly divided into treatment and control groups (40 subjects each), then treated with ETG and placebo, respectively. granulosa cells were collected and subjected to quantitative polymerase chain reaction for analyzing the expression of specific miRNA found in experiment 1. We also compared fertilization rates, high-quality embryos, and clinical pregnancy rates between the 2 groups. RESULTS: miRNA sequencing revealed differential expression of 81 miRNAs, of which 39 were downregulated, specially miR-214-3p and miR-193a-5p, whereas 42 were upregulated, specially let-7e-5p and miR-140-3p. In the second experiment, we found that miR-214-3p was significantly upregulated whereas let-7e-5p and miR-140-3p were significantly downregulated in the treatment group, relative to the control group (P < .05). Patients in the ETG treatment group exhibited a significantly higher fertilization rate than those in the control group (P < .05). CONCLUSION: ETG significantly increased fertilization rates in DOR patients with kidney deficiency syndrome and affected the expression of miR-214-3p, let-7e-5p, and miR-140-3p, the potential biomarkers.

Efficacy and Safety of the Chinese Herbal Compound TJAOA101 in Treating Diminished Ovarian Reserve: A Protocol for Multicenter, Prospective, and Pre-Post Study.

OBJECTIVE: Diminished ovarian reserve (DOR) can lead to early menopause, poor fecundity, and an increased risk of disorders such as osteoporosis, cardiovascular disease, and cognitive impairment, seriously affecting the physical and mental health of women. There is still no safe and effective strategy or method to combat DOR. We have developed a novel Chinese herbal formula, Tongji anti-ovarian aging 101 (TJAOA101), to treat DOR. However, its safety and efficacy need to be further validated. METHODS: In this prospective and pre-post clinical trial, 100 eligible patients aged 18-45 diagnosed with DOR will be recruited. All participants receive TJAOA101 twice a day for 3 months. Then, comparisons before and after treatment will be analyzed, and the outcomes, including anti-mullerian hormone (AMH) and follicle-stimulating hormone (FSH) levels and the antral follicle count (AFC), the recovery rate of menopause, and the Kupperman index (KMI), will be assessed at baseline, every month during medication (the intervention period), and 1, 3 months after medication (the follow-up period). Assessments for adverse events will be performed during the intervention and follow-up periods. CONCLUSION: A multicenter, prospective study will be conducted to further confirm the safety and efficacy of TJAOA101 in treating DOR and to provide new therapeutic strategies for improving the quality of life in DOR patients.

The effect of medical ozone therapy in addition to ovarian detorsion in ischemia reperfusion model.

This study aimed to investigate the protective effect of ozone therapy on ovarian reserve, number of ovarian follicles, ovarian morphology in a rat ischaemia reperfusion (IR) injury model. Twenty-four, Wistar Hannover rats were included. The rats were divided into three groups as control, detorsion-only, and ozone therapy + detorsion groups. There was a statistically significant difference in the follicular damage and inflammation scores between the study groups (p = .019, p = .002, respectively). The highest AMH decrease was observed in the detorsion-only group (p = .012). The total damage score was higher in the detorsion-only group than the ozone therapy + detorsion group. Preantral, small and large antral follicle numbers were less in the detorsion-only group than the ozone therapy + detorsion group. The highest postoperative day 7 TAS level was in the ozone therapy + detorsion group. TOS levels did not differ significantly between the study groups. The combination of the ozone therapy with ovarian detorsion is more effective in protecting the ovarian reserve than ovarian detorsion-only.Impact StatementWhat is already known on this subject? Adnexal torsion is a common gynecological emergency in reproductive-age women. The recommended management is the detorsion of the adnexal pedicle in patients with fertility desire.What do the results of this study add? The combination of the medical ozone therapy with conventional surgical ovarian detorsion is more effective in the protection of the ovarian reserve compared to surgical ovarian detorsion.What are the implications of these findings for clinical practice and/or further research? This study speculates that medical ozone therapy in addition to conventional surgical ovarian detorsion could preserve ovarian reserve and function if confirmed in further clinical studies.

[Effect of electroacupuncture on endometrial receptivity and IVF-ET pregnancy outcomes in patients with diminished ovarian reserve].

OBJECTIVE: To explore the effect of electroacupuncture on endometrial receptivity and the pregnancy outcomes of in vitro fertilization and embryo transfer (IVF-ET) in the patients with diminished ovarian reserve (DOR). METHODS: Sixty-eight patients of DOR undertaken IVF-ET were randomized into an observation group (34 cases, 2 cases dropped off) and a control group (34 cases, 1 case dropped off). In the control group, endometrial preparation was performed according to the routine protocol. In the observation group, on the base of the treatment as the control group, acupuncture was applied to Geshu (BL 17), Shenshu (BL 23), Mingmen (GV 4), Shiqizhui (EX-B 8), Ciliao (BL 32), Zhongliao (BL 33), Tianshu (ST 25), Qihai (CV 6) and Guanyuan (CV 4), etc. Electric stimulation was given at Ciliao (BL 32)-Zhongliao(BL 33), Tianshu (ST 25)-Zigong (EX-CA 1), with disperse-dense wave, 2 Hz/15 Hz in frequency and tolerable current in intensity. Electroacupuncture was given once every two days, 3 times weekly, lasing 3 menstrual cycles till 1 day before embryo transfer. The endometrial thickness and morphology were observed on the day of human chorionic gonadotropin (HCG) of egg retrieval cycle, the day of endometrial transformation in frozen-thawed embryo transfer (FET) cycle and the day of embryo transfer in both groups successively; as well as HCG positive rate, clinical pregnancy rate, embryo implantation rate and live birth rate. RESULTS: In the observation group, the proportion of type A endometrium on the embryo transfer day was higher than those on HCG day of the egg retrieval cycle and the endometrial transformation day of FET cycle (P<0.05), and also higher than that of the control group (P<0.01). In the observation group, HCG positive rate, clinical pregnancy rate, embryo implantation rate and live birth rate were 75.0% (24/32), 71.9% (23/32), 47.4% (27/57) and 56.3% (18/32) respectively, and all higher than 36.4% (12/33), 30.3% (10/33), 18.0% (11/61) and 15.2% (5/33) in the control group separately (P<0.01). CONCLUSION: Electroacupuncture improves the endometrial receptivity and IVF-ET pregnancy outcomes in the patients of diminished ovarian reserve.

[Ovulatory disorders under "common therapeutic principle for different diseases": essence of "Tiangui" and relationship with ovulation disorders].

The essence of the "common therapeutic principle for different diseases"(Yibing Tongzhi in Chinese for short) is the disease-syndrome combination, which is the classic mode of understanding and treating diseases in traditional Chinese medicine(TCM). This study holds the view that Yibing Tongzhi is the optimal treatment mode of ovulation disorders since ovulation disorders have the common pathogenesis, i.e., "kidney-Tiangui(reproduction-stimulating essence)-Chongren(thoroughfare and conception vessels)-uterus axis" disorder. Kidney is an important basis of the reproductive axis, where kidney essence, kidney yang, and kidney Qi are the key substances and driving forces promoting the operation of the reproductive axis. Chongren is an important transmission path. "Tiangui", the upstream substance related to the heart, brain and kidney with a connecting effect, plays a key role in the ovulation mechanism and is a representative of the reproductive axis function. There are four common Tiangui abnormalities in ovulatory disorders, including hypomenorrhea, yin and yang deficiency, abnormal exuberance of extreme yin, and abnormal phase. The dynamic changes of "Tiangui" can induce different diseases, such as polycystic ovary syndrome and hyperprolactinemia, which ultimately lead to anovulatory infertility. Therefore, with "Tiangui" as the entry point, it is the treatment trend for ovulatory disorders under Yibing Tongzhi.

The Role of Androgen Supplementation in Women With Diminished Ovarian Reserve: Time to Randomize, Not Meta-Analyze.

The management of patients with diminished ovarian reserve (DOR) remains one of the most challenging tasks in IVF clinical practice. Despite the promising results obtained from animal studies regarding the importance of androgens on folliculogenesis, the evidence obtained from clinical studies remains inconclusive. This is mainly due to the lack of an evidence-based methodology applied in the available trials and to the heterogeneity in the inclusion criteria and IVF treatment protocols. In this review, we analyze the available evidence obtained from animal studies and highlight the pitfalls from the clinical studies that prevent us from closing the chapter of this line of research.

Melatonin ameliorates ovarian dysfunction by regulating autophagy in PCOS via the PI3K-Akt pathway.

Emerging evidence has demonstrated that melatonin (MT) plays a crucial role in regulating mammalian reproductive functions. It has been reported that MT has a protective effect on polycystic ovary syndrome (PCOS). However, the protective mechanisms of MT remain poorly understood. This study aims to explore the effect of MT on ovarian function in PCOS and to elucidate the relevant molecular mechanisms in vivo and in vitro. We first analysed MT expression levels in the follicular fluid of PCOS patients. A significant reduction in MT expression levels was noted in PCOS patients. Intriguingly, reduced MT levels correlated with serum testosterone and inflammatory cytokine levels in follicular fluid. Moreover, we confirmed the protective function of MT through regulating autophagy in a DHEA-induced PCOS rat model. Autophagy was activated in the ovarian tissue of the PCOS rat model, whereas additional MT inhibited autophagy by increasing PI3K--Akt pathway expression. In addition, serum-free testosterone, inflammatory and apoptosis indexes were reduced after MT supplementation. Furthermore, we also found that MT suppressed autophagy and apoptosis by activating the PI3K-Akt pathway in the DHEA-exposed human granulosa cell line KGN. Our study showed that MT ameliorated ovarian dysfunction by regulating autophagy in DHEA-induced PCOS via the PI3K-Akt pathway, revealing a potential therapeutic drug target for PCOS.

The Protective Effects of L-Carnitine and Zinc Oxide Nanoparticles Against Diabetic Injury on Sex Steroid Hormones Levels, Oxidative Stress, and Ovarian Histopathological Changes in Rat.

Diabetes mellitus is a common chronic metabolic disorder. This study aimed to investigate the effects of co-treatment with L-carnitine (LC) and zinc oxide nanoparticles (ZnONPs) on serum levels of sex hormones, oxidative stress, and ovarian histopathology in streptozotocin (STZ)-induced diabetic rats. Female Wistar rats (n = 56, 180-220 g) received a single intraperitoneal (IP) injection of STZ (65 mg/kg). They were randomly assigned into the following groups: diabetic group (Dia), Dia+Met group (100 mg metformin/kg/day), Dia+LC group (200 mg/kg/day), Dia+ZnONPs group (10 mg/kg/day), and Dia+LC+ZnONPs group (200 mg LC/kg/day and 10 mg ZnONPs/kg/day). Control group (Ctl) received the same volume of STZ solvent. After 21 days of treatment, blood serum was centrifuged for sex hormone assays. The right ovary was used for biochemical analysis, and the left ovary was fixed in 10% neutral buffered formalin for histological assessment. The levels of estradiol, progesterone, FSH, and LH significantly increased in the Dia+ZnONPs+LC group (P < 0.001) compared with the Dia group. Co-treatment with LC and ZnONPs reduced malondialdehyde and carbonyl protein and increased glutathione, catalase, and superoxide dismutase activities in ovarian tissue compared with the Dia group (P < 0.05). Moreover, the number of all ovarian follicles significantly increased in this group compared with the Dia group (P < 0.05). The results of this study indicated that co-treatment with LC and ZnONPs could preserve ovarian function by increasing sex hormones levels and antioxidant activity and decreasing lipid peroxidation in diabetic rats. Therefore, this compound supplementation may improve ovulation and fertility in people with diabetes mellitus.

Downregulation of lncrna uca1 as a diagnostic and prognostic biomarker for ovarian endometriosis

SUMMARY OBJECTIVE: Ovarian endometriosis seriously affects the quality of life of females, and long non-coding RNA lncRNA urothelial carcinoma-associated 1 (UCA1) plays pivotal roles in the pathogenesis of various ovarian diseases. However, the involvement of lncRNA UCA1 in ovarian endometriosis remains unknown to date. Therefore, the present study aims to study the role of UCA1 in ovarian endometriosis. METHODS: A total of 98 patients with ovarian endometriosis and 28 healthy females were included. The expression of lncRNA UCA1 in ectopic and eutopic endometrium tissues of ovarian endometriosis patients and controls was detected using qRT-PCR. A ROC curve analysis was performed to evaluate the diagnostic values of serum lncRNA UCA1 for ovarian endometriosis. Patients were followed up for 2 years after discharge, and the recurrence of ovarian endometriosis was recorded. RESULTS: The expression level of lncRNA UCA1 was significantly higher in ectopic endometrium tissues than in paired eutopic endometrium tissues for most of the patients. The serum lncRNA UCA1 level showed no significant correlations with either patients' age or living habits. After the treatment, the serum lncRNA UCA1 level increased, and serum levels of lncRNA UCA1 on the day of discharge were significantly lower in patients with recurrence than those in patients without recurrence. Conclusion: The downregulation of lncRNA UCA1 is involved in the pathogenesis of ovarian endometriosis and may serve as a promising diagnostic and prognostic biomarker for the disease.

RESUMO OBJETIVO: A endometriose ovariana afeta seriamente a qualidade de vida das mulheres, e o carcinoma urotelial 1 de urcélio de RNA não codificador longo 1 (UCA1) desempenha um papel crucial na patogênese de várias doenças ovarianas. No entanto, o envolvimento do lncRNA UCA1 na endometriose ovariana permanece desconhecido até o momento. Portanto, o presente estudo tem como objetivo estudar o papel do UCA1 na endometriose ovariana. Métodos: Um total de 98 pacientes com endometriose ovariana e de 28 mulheres saudáveis foi incluído. A expressão de lncRNA UCA1 em tecidos de endométrio ectópico e eutópico de pacientes com endometriose ovariana e controles foi detectada por qRT-PCR. A análise da curva ROC foi realizada para avaliar os valores diagnósticos do lncRNA UCA1 sérico para endometriose ovariana. Os pacientes foram acompanhados por dois anos após a alta, e a recorrência da endometriose ovariana foi registrada. RESULTADOS: O nível de expressão do lncRNA O UCA1 foi significativamente maior nos tecidos do endométrio ectópico do que nos tecidos do endométrio eutópico pareados para a maioria dos pacientes. O nível sérico de UCA1 foi diminuído com a progressão da endometriose ovariana. O soro UCA1 pode ser usado para diagnosticar com precisão a endometriose ovariana. O nível sérico de UCA1 não apresentou correlações significativas com a idade ou com os hábitos de vida dos pacientes. Após o tratamento, o nível sérico do lncRNA UCA1 foi aumentado, e os níveis séricos de lncRNA UCA1 no dia da alta foram significativamente menores nos pacientes com recidiva do que naqueles sem recorrência. CONCLUSÃO: A regulação negativa do lncRNA UCA1 está envolvida na patogênese da endometriose ovariana e pode servir como um promissor biomarcador diagnóstico e prognóstico para a doença.

Heavy black tea consumption and elevated CA 19-9 and CA 125 levels. A case report on a patient with ovarian endometriotic cysts.

In this case report, we present a case of false positive CA 19-9 and CA 125 levels in a patient with suspected endometriotic cysts. The patient is a 34-year-old nulliparous woman with heavy black tea consumption and elevated CA 19-9 and CA 125 levels. After discontinuation of black tea intake and careful exploration of other possible factors, CA 19-9 and CA 125 levels dropped markedly. As a conclusion, heavy black tea consumption can lead to false positive results of elevated CA 19-9 and CA 125 levels.

Role of a natural integrator based on lipoic acid, palmitoiletanolamide and myrrh in the treatment of chronic pelvic pain and endometriosis.

BACKGROUND: Dysmenorrhea and chronic pelvic pain occur in a significantly higher percentage in women with endometriosis; this benign condition has an incidence ranging from 5% to 10% in the general population, while 35% to 50% of infertile women are affected. Treatment of the symptoms demands integrated approaches with the use of anti-inflammatory substances or drugs and lifestyle changes, including attention to diet. The use of traditional anti-inflammatory drugs over the long term is not very successful because of the fear of side effects so they are almost always used with a short-term formula of 7-10 days when the woman's general condition becomes difficult to bear. In recent years, particular attention has been paid to natural substances with recognized anti-inflammatory activities that, associated with one another, are able to synergize individual actions. A nutraceutical containing substances capable of fighting chronic pelvic pain has recently been put on the market. The possible action mechanism derives from a synergy of action between alpha-lipoic acid, palmitoiletanolamide (PEA) and myrrh (Pelvinox, Laborest Italia srl, Nerviano, Milan, Italy), whose action is so effective that it is able to replace the use of anti-inflammatory drugs. The aim of the study was to evaluate the effect of these active ingredients in women with endometriosis and chronic pelvic pain. METHODS: This multicenter study saw the recruitment of 60 women (divided between the three centers participating in the study, Siena, Bologna and Udine) aged between 20 and 39 suffering from endometriosis (ovarian) and chronic pelvic pain. All the women took one nutraceutical (Pelvinox) at a dose of two tablets per day for 6 months. RESULTS: The results showed a significant reduction in pain symptoms as regards dyspareunia, dysmenorrhea and chronic pelvic pain, while there was no change in the mean diameter of the endometriosis cysts. CONCLUSIONS: In light of the above, it is believed that substances such as alpha-lipoic acid, PEA and myrrh may play a very important role in this type of patient in the treatment of individual symptoms.

Review of Endometriosis Diagnosis through Advances in Biomedical Engineering.

Endometriosis is characterized as the ectopic presence of endometrium in various locations within the abdominal cavity, such as the fallopian tube, the pouch of Douglas, the ovaries, outside the ovaries, and more. The inner lining of the uterus, endometrium, is a dynamic tissue that undergoes morphological and functional changes cyclically. The proliferation of endometrial cells during menstruation is influenced by increasing circulating estrogen levels. Adult progenitor stem cells are likely responsible for this remarkable regenerative capacity and hence, enhanced capacity to generate endometriosis. This chronic estrogen-dependent disease is characterized by the ectopic endometrial implant. The disorder occurs in 6%-10% of reproductive-aged women and in 35%-50% of women with pelvic pain and infertility. Currently, the preferred diagnostic methods are laparoscopic inspection by transvaginal ultrasound, MRI, and sensors. Diagnoses with transvaginal ultrasound have 92.7% sensitivity and 97% specificity in detecting endometriotic lesions. On average, MRI diagnoses of DIE have 74% sensitivity and 95% specificity. Lastly, chemical sensors have 91.7% sensitivity and 90.0% specificity in detecting endometriosis. The standard of care includes personalizing the treatment plan based on the individual's set of symptoms and their severity. Advances in biomedical engineering have aided professionals in personalizing the course of treatments as well as to increasing the quality of life of these patients through various therapies for managing pain. Because no one theory provides a full explanation for the manifestation of the disease, hormonal therapies, targeted therapeutics, and surgical options have emerged as elements of disease management. Clinicians are in the process of developing advanced pharmaceutical drugs with specific orphan target receptors of the ectopic tissue. Possible complications that accompany the condition include dyspareunia, hyperalgesia, infertility, and many others.

Investigation of Allium sativum's protective effect on ovarian reserve in an experimental ovarian injury model / Investigación del efecto protector de Allium sativum de la reserva ovárica en un modelo experimental de lesión ovárica

We aimed to evaluate the effects of detorsion and Allium sativum (garlic oil) treatment on the ovarian reserve in an ovarian torsion model. Ovarian torsion may lead to loss of ovarian tissue and infertility. It is an experimental rat study that was carried out on 16 sets of ovaries each, one for treatment group and a control group. In the control group, the procedure involved only the surgically opening and closing the abdomen. Bilateral adnexal torsion/detorsion was performed after a 3-hour ischemia period for the detorsion-only group. The detorsion + Allium sativum group received a 5 ml/kg dose of Allium sativum intraperitoneally, 2 hours before surgery. After the second surgery, removed ovarian samples were evaluated for follicle counts, damage scores and other parameters. Primordial, preantral, small antral and large antral follicle counts were significantly higher in the detorsion + Allium sativum group. Degeneration, congestion, hemorrhage ,inflammation and total damage scores were significantly elevated in the detorsion only group compared to those for the detorsion + Allium sativum group. Finally, there was a significant correlation between AMH alterations and postoperative, preantral follicle count (p<0.05). As a conclusion detorsion + Allium sativum treatment may be effective in protecting the ovarian reserve after torsion.

Intentamos evaluar los efectos de la detorsión y el tratamiento con Allium sativum (aceite de ajo) en la reserva ovárica en un modelo de torsión ovárica. La torsión ovárica puede ocasionar pérdida de tejido ovárico e infertilidad. Este es un estudio experimental en ratas que se llevó a cabo en 16 sets de ovarios para cada grupo: tratamiento y control. En el grupo control, el procedimiento involucró solamente la apertura y el cierre quirúrgicos del abdomen. La torsión / detorsión anexial bilateral se realizó después de un período de isquemia de 3 horas para el grupo de solo detorsión. El grupo de detorsión + Allium sativum recibió una dosis de 5 ml / kg de Allium sativum por vía intraperitoneal, 2 horas antes de la cirugía. Después de la segunda cirugía, las muestras ováricas eliminadas se evaluaron para recuentos de folículos, puntajes de daño y otros parámetros. Los recuentos de folículos antrales primordiales, preantrales, antrales pequeños y grandes fueron significativamente mayores en el grupo con detorsión + Allium sativum. Los puntajes de degeneración, congestión, hemorragia, inflamación y daño total fueron significativamente elevados en el grupo de solo detorsión, en comparación con los del grupo de detorsión + Allium sativum. Finalmente, hubo una correlación significativa entre las alteraciones de AMH y el recuento de folículos preantrales postoperatorios (p <0,05). Como conclusión, el tratamiento con detorsión + Allium sativum puede ser eficaz para proteger la reserva ovárica después de la torsión.

Nigella Sativa Oil Protects the Rat Ovary from Oxidative Injury Due to Ischemia-Reperfusion.

BACKGROUND The aim of this study was to evaluate the effects of Nigella sativa (N. sativa) oil (NSO) on ovarian oxidative damage following ischemia-reperfusion injury, using a rat model of ovarian torsion. MATERIAL AND METHODS Forty-eight female albino Wistar rats were divided into six groups: (Group 1) laparotomy only; (Group 2) intraperitoneal NSO (2 ml/kg), 1 hour following laparotomy; (Group 3) 3 hours of ovarian ischemia; (Group 4) 3 hours of ovarian ischemia followed by 3 hours of reperfusion; (Group 5) 3 hours of ovarian ischemia and 2 ml/kg of NSO 1 hour before laparotomy; (Group 6) 3 hours of reperfusion after 3 hours of ovarian ischemia and 2 ml/mg of NSO 1 hour before laparotomy. RESULTS The antioxidant status, ceruloplasmin level, native thiol, total thiol, and disulfide levels of the control group (Group 1) were significantly increased compared with the ovarian ischemia-reperfusion group treated with NSO (Group 6) (p=0.003, p=0.002, p=0.006, p=0.001 and p=0.003, respectively); these levels in the ovarian ischemia group (Group 3) and ischemia-reperfusion group (Group 4) were statistically similar to those of the ovarian ischemia + NSO group (Group 5) and ovarian ischemia-reperfusion + NSO group (Group 6). CONCLUSIONS In this preliminary rat study, administration of NSO shortly after the onset of ovarian ischemia-reperfusion injury, did not significantly reduce levels of markers of oxidative injury. Further studies are required to evaluate the ovarian changes at the tissue level, and to determine the optimum dose of NSO.

Lycium barbarum polysaccharide attenuates chemotherapy-induced ovarian injury by reducing oxidative stress.

AIM: We aimed to examine the effects of Lycium barbarum polysaccharide (LBP) on ovarian damage induced by cyclophosphamide (CTX) and to investigate the underlying mechanism. METHODS: A total of 240 female Sprague-Dawley rats were randomly divided into five groups: the control group, the CTX-induced ovarian injury (OI) group, and three LBP groups. Different concentrations of LBP solution were administered to the LBP groups by gastric infusion for 15 days, and the OI group and LBP groups were then subjected to CTX treatment for another 15 days. On days 7, 14, and 28 after CTX injection, femoral vein blood and ovarian tissues were collected for the measurements of antioxidant enzymes and oxidation products. Serum indicators were measured by enzyme-linked immunosorbent assay; and Nrf2, heme oxygenase-1, and quinone oxidoreductase 1 protein levels were detected by Western blot analysis. RESULTS: LBP attenuated CTX-induced ovarian damage and reversed associated adverse effects. LBP reduced oxidative stress by enhancing the potency of antioxidant enzymes and attenuating elevated levels of oxidation products following CTX injection. Furthermore, LBP upregulated Nrf2, heme oxygenase-1, and quinone oxidoreductase 1 protein expression. CONCLUSION: LBP exerts protective effects against CTX-induced ovarian injury by reducing oxidative stress and activating the Nrf2/ARE-signaling pathway.
