RESUMEN

Purpose: This study aims to retrospectively estimate cumulative reproductive outcomes in women with primary ovarian insufficiency (POI) in assisted reproductive technology (ART) therapy. Methods: A total of 139 patients diagnosed with POI were reviewed in this study. Firstly, they were divided into two groups according to oocyte origin: using their own oocytes (OG group) or accepting oocyte donations (OD I group). Secondly, the patients were split depending on the pregnancy outcome. In the OG group, nine patients decided to use others' oocytes after a failure of attempting to use their own, and this population was the oocyte donation II group (OD II group). Results: There were 88 patients who used their own oocytes, while 51 patients accepted oocyte donations. In the OG group, there are only 10 (7.2%) patients who got pregnant, and patients in the OD group had worse hormone levels (FSH 71.37 ± 4.18 vs. 43.98 ± 2.53, AMH 0.06 ± 0.04 vs. 1.15 ± 0.15, and AFC 0.10 ± 0.06 vs. 1.15 ± 0.15) and more years of infertility (5.04 ± 0.48 vs. 3.82 ± 0.30), which explained why they choose oocyte donation. In all the three groups, baseline characteristics were comparable between pregnant women and non-pregnant women. Of the 10 pregnant patients in the OG group, four of them used luteal-phase short-acting long protocol and had pregnancies successfully in their first cycles. Conclusion: Ovarian stimulation in POI women requires more cost and time. For those with a stronger desire to have genetic offspring, luteal-phase short-acting long protocol may help them obtain pregnancy rapidly.

RESUMEN

This review focuses on primary amenorrhea and primary/premature ovarian insufficiency due to hypergonadotropic hypogonadism. Following a thoughtful, thorough evaluation, a diagnosis can usually be discerned. Pubertal induction and ongoing estrogen replacement therapy are often necessary. Shared decision-making involving the patient, family, and health-care team can empower the young person and family to successfully thrive with these chronic conditions.

RESUMEN

BACKGROUND: Chemotherapy exposure has become a main cause of premature ovarian insufficiency (POI). This study aimed to evaluate the role and molecular mechanism of human umbilical cord mesenchymal stem cell-derived exosomes (hUMSC-Exos) in ovarian function protection after chemotherapy. METHODS: hUMSC-Exos were applied to cyclophosphamide-induced premature ovarian insufficiency mice and human ovarian granulosa tumor cells (KGN) to determine their effects on follicular development and granulosa cell apoptosis. Evaluation was done for iron ion and reactive oxygen species (ROS) production, lipid peroxidation levels, and changes in iron death-related molecules (nuclear factor (erythroid-derived 2)-like 2 (Nrf2), Glutathione Peroxidase enzyme 4 (GPX4), and Solute carrier family 7 member 11 cystine glutamate transporter (SLC7A11; xCT)). Furthermore, rescue experiments using an Nrf2 inhibitor were performed to assess the therapeutic effects of hUMSC-Exos on granulosa cells. RESULTS: hUMSC-Exos promoted ovarian hormone levels and primary follicle development in POI mice and reduced granulosa cell apoptosis. After hUMSC-Exos treatment, the ROS production, free iron ions and lipid peroxidation levels of granulosa cells decreased, and the iron death marker proteins Nrf2, xCT and GPX4 also decreased. Furthermore, the Nrf2 inhibitor ML385 significantly attenuated the effects of hUMSC-Exos on granulosa cells. CONCLUSION: hUMSC-Exos inhibit ferroptosis and protect against CTX-induced ovarian damage and granulosa cell apoptosis through the Nrf2/GPX4 signaling pathway, revealing a novel mechanism of hUMSC-Exos in POI therapy.

RESUMEN

Umbilical cord-derived mesenchymal stem cell (UCMSC) transplantation has been deeply explored for premature ovarian insufficiency (POI) disease. However, the associated mechanism remains to be researched. To explore whether and how the microRNA 21 (miR-21) functions in POI mice with UCMSCs transplantation, the autoimmune-induced POI mice model was built up, transplanted with or without UCMSCs transfect with the LV-hsa-miR-21-5p/LV-hsa-miR-21-5p-inhibition, with the transfection efficiency analyzed by QRT-PCR. Mice hormone secretion and the anti-Zona pellucida antibody (AZPAb) levels were analyzed, the ovarian morphological changes and folliculogenesis were observed, and the ovarian apoptosis cells were detected to evaluate ovarian function. The expression and localization of the PTEN/Akt/FOXO3a signal pathway-related cytokines were analyzed in mice ovaries.Additionally, the spleen levels of CD8 + CD28-T cells were tested and qualified with its significant secretory factor, interleukin 10 (IL-10). We found that with the LV-hsa-miR-21-5p-inhibition-UCMSCs transplantation, the mice ovarian function can be hardly recovered than mice with LV-NC-UCMSCs transplantation, and the PTEN/Akt/FOXO3a signal pathway was activated. The expression levels of the CD8 + CD28-T cells were decreased, with the decreased levels of the IL-10 expression. In contrast, in mice with the LV-hsa-miR-21-5p-UCMSCs transplantation, the injured ovarian function can be reversed, and the PTEN/AKT/FOXO3a signal pathway was detected activated, with the increased levels of the CD8 + CD28-T cells, and the increased serum levels of IL-10. In conclusion, miR-21 improves the ovarian function recovery of POI mice with UCMSCs transplantation, and the mechanisms may be through suppressing the PTEN/AKT/FOXO3a signal pathway and up-regulating the circulating of the CD8 + CD28-T cells.

RESUMEN

BACKGROUND: Premature ovarian insufficiency (POI) is a major cause of infertility. In this study, we aimed to investigate the effects of the combination of bone marrow mesenchymal stem cells (BMSCs) and moxibustion (BMSCs-MOX) on POI and evaluate the underlying mechanisms. METHODS: A POI rat model was established by injecting different doses of cyclophosphamide (Cy). The modeling of POI and the effects of the treatments were assessed by evaluating estrous cycle, serum hormone levels, ovarian weight, ovarian index, and ovarian histopathological analysis. The effects of moxibustion on BMSCs migration were evaluated by tracking DiR-labeled BMSCs and analyzing the expression of chemokines stromal cell-derived factor 1 (Sdf1) and chemokine receptor type 4 (Cxcr4). Mitochondrial function and mitophagy were assessed by measuring the levels of reactive oxygen species (ROS), mitochondrial membrane potential (MMP), ATP, and the mitophagy markers (Drp1, Pink1, and Parkin). Furthermore, the mitophagy inhibitor Mdivi-1 and the mitophagy activator CCCP were used to confirm the role of mitophagy in Cy-induced ovarian injury and the underlying mechanism of combination therapy. RESULTS: A suitable rat model of POI was established using Cy injection. Compared to moxibustion or BMSCs transplantation alone, BMSCs-MOX showed improved outcomes, such as reduced estrous cycle disorders, improved ovarian weight and index, normalized serum hormone levels, increased ovarian reserve, and reduced follicle atresia. Moxibustion enhanced Sdf1 and Cxcr4 expression, promoting BMSCs migration. BMSCs-MOX reduced ROS levels; upregulated MMP and ATP levels in ovarian granulosa cells (GCs); and downregulated Drp1, Pink1, and Parkin expression in ovarian tissues. Mdivi-1 significantly mitigated mitochondrial dysfunction in ovarian GCs and improved ovarian function. CCCP inhibited the ability of BMSCs-MOX treatment to regulate mitophagy and ameliorate Cy-induced ovarian injury. CONCLUSIONS: Moxibustion enhanced the migration and homing of BMSCs following transplantation and improves their ability to repair ovarian damage. The combination of BMSCs and moxibustion effectively reduced the excessive activation of mitophagy, which helped prevent mitochondrial damage, ultimately improving ovarian function. These findings provide a novel approach for the treatment of pathological ovarian aging and offer new insights into enhancing the efficacy of stem cell therapy for POI patients.

RESUMEN

OBJECTIVE: To establish a set of clinician and patient-reported outcome measures (PROMs) and present the initial findings of a value-based healthcare (VBHC) program in patients with premature ovarian insufficiency (POI). METHODS: Employing a four-phase approach, we identified the most crucial domains for patients with POI and translated these into PROMs. Prior to each visit, patients completed questionnaires to evaluate: depression (BDI-II), menopausal symptoms (GCS), work ability (WAS) and infertility (FertiQoL). During the visits, cardiovascular health assessments and dual-energy X-ray absorptiometry (DEXA) scans to measure bone mineral density were performed. Data at intake is presented, and comparisons are drawn between women using and those not using hormone replacement therapy (HRT). Patient-reported experience measures (PREMs) were evaluated by a questionnaire. RESULTS: A total of 267 POI patients completed the PROM questionnaires, of whom 58.1 % were using HRT at intake. Over half of the patients (53.5 %), had a BDI-II score of 14 or higher, indicating mild to severe depression. The mean total GCS score was 20.9 (SD 11.3). The median work ability score was 7.5 (IQR 6.0-8.0) and the mean FertiQoL score 63.9 (SD 15.7). Additionally, 22.7 % of patients presented with hypertension, 6.2 % with hypercholesterolemia, and almost 50 % had low bone mass. Patients rated the VBHC program with a mean of 8.6 (SD 1.2). CONCLUSIONS: These findings underscore the necessity of a multidisciplinary VBHC program incorporating standardized screening and psychological treatment. We advocate for the implementation of patient-centered outcomes for clinical practice, which have been found to be highly relevant by patients with POI.

RESUMEN

Premature loss of ovarian function (POI) is associated with numerous negative side effects, including vasomotor symptoms, sleep and mood disturbances, disrupted urinary function, and increased risks for osteoporosis and heart disease. Hormone replacement therapy (HRT), the standard of care for POI, delivers only a subset of ovarian hormones and fails to mimic the monthly cyclicity and daily pulsatility characteristic of healthy ovarian tissue in reproductive-aged individuals whose ovarian tissue contains thousands of ovarian follicles. Ovarian tissue allografts have the potential to serve as an alternative, cell-based HRT, capable of producing the full panel of ovarian hormones at physiologically relevant doses and intervals. However, the risks associated with systemic immune suppression (IS) required to prevent allograft rejection outweigh the potential benefits of comprehensive and dynamic hormone therapy. This work investigates whether the age of ovarian tissue donor animals affects the function of, and immune response to, subcutaneous ovarian grafts. We performed syngeneic and semi-allogeneic ovarian transplants using tissue from mice aged 6-8 (D7) or 20-22 (D21) days and evaluated ovarian endocrine function and immune response in a mouse model of POI. Our results revealed that tissue derived from D7 donors, containing an ample and homogeneous primordial follicle reserve, was more effective in fully restoring hypothalamic-pituitary-ovarian feedback. In contrast, tissue derived from D21 donors elicited anti-donor antibodies with higher avidity compared to tissue from younger donors, suggesting that greater immunogenicity may be a trade-off of using mature donors. This work contributes to our understanding of the criteria donor tissue must meet to effectively function as a cell-based HRT and explores the importance of donor age as a factor in ovarian allograft rejection.

RESUMEN

Premature ovarian insufficiency (POI) is an essential cause of reduced fertility and quality of life in young women. Mesenchymal stem cells (MSCs) and MSCs-derived extracellular vesicles (EVs) have the ability to migrate to damaged tissues and are considered as promising therapeutic approaches for POI. However, the homing ability and therapeutic efficacy of MSCs administered in vivo are still insufficient, and their potential tumorigenicity and multi-differentiation potential also bring many doubts about their safety. The targeting ability and migration efficiency of MSCs can be improved by genetic engineering and surface modification, thereby maximizing their therapeutic efficacy. However, the use of viral vectors also has increased safety concerns. In addition, EVs, which seem to be the current therapeutic alternative to MSCs, are still poorly targeted for distribution, although they have improved in terms of safety. This paper reviews the comparative therapeutic effects of MSCs and their derived EVs on POI, their biodistribution after in vivo administration, and the most important possible ovarian targeting strategies. Difficulties such as homogeneity and yield before clinical application are also discussed. This article will provide new insights into precision therapy and targeted drug delivery for female ovarian diseases.

RESUMEN

BACKGROUND: Premature ovarian failure (POF) has a profound impact on female reproductive and psychological health. In recent years, the transplantation of umbilical cord-derived mesenchymal stem cells (UC-MSCs) has demonstrated unprecedented potential in the treatment of POF. However, the heterogeneity of human UC-MSCs remains a challenge for their large-scale clinical application. Therefore, it is imperative to identify specific subpopulations within UC-MSCs that possess the capability to improve ovarian function, with the aim of reducing the uncertainty arising from the heterogeneity while achieving more effective treatment of POF. METHODS: 10 × Genomics was performed to investigate the heterogeneity of human UC-MSCs. We used LRP1 as a marker and distinguished the potential therapeutic subpopulation by flow cytometry, and determined its secretory functions. Unsorted UC-MSCs, LRP1high and LRP1low subpopulation was transplanted under the ovarian capsules of aged mice and CTX-induced POF mice, and therapeutic effects was evaluated by assessing hormone levels, estrous cycles, follicle counts, and embryo numbers. RNA sequencing on mouse oocytes and granulosa cells after transplantation was performed to explore the mechanism of LRP1high subpopulation on mouse oocytes and granulosa cells. RESULTS: We identified three distinct functional subtypes, including mesenchymal stem cells, multilymphoid progenitor cells and trophoblasts. Additionally, we identified the LRP1high subpopulation, which improved ovarian function in aged and POF mice. We elucidated the unique secretory functions of the LRP1high subpopulation, capable of secreting various chemokines, cytokines, and growth factors. Furthermore, LRP1 plays a crucial role in regulating the ovarian microenvironment, including tissue repair and extracellular matrix remodeling. Consistent with its functions, the transcriptomes of oocytes and granulosa cells after transplantation revealed that the LRP1high subpopulation improves ovarian function by modulating the extracellular matrix of oocytes, NAD metabolism, and mitochondrial function in granulosa cells. CONCLUSION: Through exploration of the heterogeneity of UC-MSCs, we identified the LRP1high subpopulation capable of improving ovarian function in aged and POF mice by secreting various factors and remodeling the extracellular matrix. This study provides new insights into the targeted exploration of human UC-MSCs in the precise treatment of POF.

RESUMEN

PURPOSE OF REVIEW: Pre-menopausal women diagnosed with hormone receptor (HR) breast cancer are candidates for prolonged hypoestrogenism to improve cancer outcomes. However, the disease benefit eclipses the toxicities associated with ovarian function suppression (OFS), which are often under-reported. RECENT FINDINGS: Increased risk of mortality from cardiovascular disease, bone disorders, and metabolic disorders is well reported in women with no history of cancer, after surgical oophorectomy or premature ovarian failure. Vasomotor symptoms, urogenital atrophy, weight gain, sexual dysfunction, cognitive decline, and sleep disturbances contribute to the increased non-compliance associated with OFS, especially in younger women. Balancing the toxicities of prolonged OFS with its benefits should be critically analyzed by providers when making recommendations for their patients. Supportive care to manage multi-system toxicities and to counteract the long-term impact on all-cause mortality should be emphasized by every cancer program. Future studies with OFS should incorporate patient outcomes and strategies for symptom management in addition to focusing on improving disease outcomes.

RESUMEN

Premature ovarian insufficiency (POI) patients experience a decline in ovarian function and a reduction in serum reproductive hormones, leading to a significant impact on the outcomes of assisted reproductive technology. Despite the absence of an effective clinical treatment to restore fertility in POI patients, recent research has indicated that cord blood plasma (CBP) derived from human umbilical cord blood (hUCB) may offer therapeutic benefits for various degenerative diseases. The primary aim of this study is to explore approaches for enhancing ovarian function and serum reproductive hormones through the administration of CBP in a murine model. Initially, hUCB was utilized to obtain CBP (CBP), which was subsequently analyzed for cytokine and growth factor profiles in comparison to adult blood plasma (ABP) by use of flow cytometry. Subsequently, POI mouse models were established through the induction of 4-vinylcyclohexene diepoxide, followed by the injection of CBP into the tail. At 7, 14, and 21 days posttreatment, mouse ovaries and blood were collected, and their estrus cycle, body weight, and ovarian weights were evaluated using precise electronic balance. Finally, ovarian morphology and follicle number were assessed through HE staining, while serum levels of anti-Müllerian hormone (AMH), estradiol (E2) and follicle-stimulating hormone (FSH) were determined by ELISA. Our study revealed that individuals with CBP exhibited significantly lower concentrations of proinflammatory cytokines, including IL-ß (p < 0.01) and IL-2 (p < 0.05), while displaying elevated levels of anti-inflammatory cytokines and chemokines, such as IL-2, IL-4, IL-6, IL-8, IL-12P70, IL-17A, IP-10, interferon-γ, and tumor necrosis factor-α (p < 0.01). Furthermore, CBP demonstrated remarkably higher levels of growth factors, including transforming growth factor-ß1, vascular endothelial growth factor, and insulin-like growth factor-1 (p < 0.01) than ABP. Notably, our investigation also revealed that CBP restored the content of serum reproductive hormones, such as AMH, E2, and FSH (p < 0.05), and increased the number of primordial and primary follicles (p < 0.01) and decreased the number of luteal and atretic follicles (p < 0.01) in vivo. Our findings suggested that CBP-secreted cytokines and growth factors could be restored POI ovarian function, enhanced serum reproductive hormones and rescued follicular development in vivo. These findings further support the potential of CBP as a promising strategy in clinical applications for POI related infertility.

RESUMEN

OBJECTIVE: This study aims to investigate the effects of natural products on animal models of premature ovarian failure (POF). METHODS: We conducted comprehensive literature searches and identified relevant studies that examined the protective effects of natural products on experimental POF. We extracted quantitative data on various aspects such as follicular development, ovarian function, physical indicators, oxidative stress markers, inflammatory factors, and protein changes. The data was analyzed using random-effects meta-analyses, calculating pooled standardized mean differences and 95% confidence intervals. Heterogeneity was assessed using the I2 statistic, and bias was estimated using the SYRCLE tool. RESULTS: Among the 879 reviewed records, 25 articles met our inclusion criteria. These findings demonstrate that treatment with different phytochemicals and marine natural products (flavonoids, phenols, peptides, and alkaloids, etc.) significantly improved various aspects of ovarian function compared to control groups. The treatment led to an increase in follicle count at different stages, elevated levels of key hormones, and a decrease in atretic follicles and hormone levels associated with POF. This therapy also reduced oxidative stress (specifically polyphenols, resveratrol) and apoptotic cell death (particularly flavonoids, chrysin) in ovarian granulosa cells, although it showed no significant impact on inflammatory responses. The certainty of evidence supporting these findings ranged from low to moderate. CONCLUSIONS: Phytochemicals and marine natural product therapy (explicitly flavonoids, phenols, peptides, and alkaloids) has shown potential in enhancing folliculogenesis and improving ovarian function in animal models of POF. These findings provide promising strategies to protect ovarian reserve and reproductive health. Targeting oxidative stress and apoptosis pathways may be the underlying mechanism.

RESUMEN

BACKGROUND: Clinically, hormone replacement therapy (HRT) is the main treatment for primary ovarian insufficiency (POI). However, HRT may increase the risk of both breast cancer and cardiovascular disease. Exosomes derived from human umbilical cord mesenchymal stem cell (hUC-MSC) have been gradually applied to the therapy of a variety of diseases through inflammation inhibition, immune regulation, and tissue repair functions. However, the application and study of hUC-MSC exosomes in POI remain limited. METHODS: Here, we first constructed four rat animal models: the POI-C model (the "cyclophosphamide-induced" POI model via intraperitoneal injection), the POI-B model (the "busulfan-induced" POI model), the POI-U model (the "cyclophosphamide-induced" POI model under ultrasonic guidance), and MS model (the "maternal separation model"). Second, we compared the body weight, ovarian index, status, Rat Grimace Scale, complications, and mortality rate of different POI rat models. Finally, a transabdominal ultrasound-guided injection of hUC-MSC exosomes was performed, and its therapeuticy effects on the POI animal models were evaluated, including changes in hormone levels, oestrous cycles, ovarian apoptosis levels, and fertility. In addition, we performed RNA-seq to explore the possible mechanism of hUC-MSC exosomes function. RESULTS: Compared with the POI-C, POI-B, and MS animal models, the POI-U model showed less fluctuation in weight, a lower ovarian index, fewer complications, a lower mortality rate, and a higher model success rate. Second, we successfully identified hUC-MSCs and their exosomes, and performed ultrasound-guided intraovarian hUC-MSCs exosomes injection. Finally, we confirmed that the ultrasound-guided exosome injection (termed POI-e) effectively improved ovarian hormone levels, the oestrous cycle, ovarian function, and fertility. Mechanically, hUC-MSCs may play a therapeutic role by regulating ovarian immune and metabolic functions. CONCLUSIONS: In our study, we innovatively constructed an ultrasound-guided ovarian drug injection method to construct POI-U animal models and hUC-MSC exosomes injection. And we confirmed the therapeutic efficacy of hUC-MSC exosomes on the POI-U animal models. Our study will offer a better choice for new animal models of POI in the future and provides certain guidance for the hUC-MSCs exosome therapy in POI patients.

RESUMEN

Premature ovarian insufficiency (POI), also known as premature menopause or premature ovarian failure, signifies the partial or complete loss of ovarian endocrine function and fertility before 40 years of age. This condition affects approximately 1% of women of childbearing age. Although 5-10% of patients may conceive naturally, conventional infertility treatments, including assisted reproductive technology, often prove ineffective for the majority. For infertile patients with POI, oocyte donation or adoption exist, although a prevalent desire persists among them to have biological children. Stem cells, which are characterized by their undifferentiated nature, self-renewal capability, and potential to differentiate into various cell types, have emerged as promising avenues for treating POI. Stem cell therapy can potentially reverse the diminished ovarian endocrine function and restore fertility. Beyond direct POI therapy, stem cells show promise in supplementary applications such as ovarian tissue cryopreservation and tissue engineering. However, technological and ethical challenges hinder the widespread clinical application of stem cells. This review examines the current landscape of stem cell therapy for POI, underscoring the importance of comprehensive assessments that acknowledge the diversity of cell types and functions. Additionally, this review scrutinizes the limitations and prospects associated with the clinical implementation of stem cell treatments for POI.

RESUMEN

The term "ovarian insufficiency" describes the decline of ovarian function resulting in fertility loss and the marked decrease of ovarian steroid hormone production. From a clinical standpoint, ovarian insufficiency presents in three different settings. The first is natural menopause at midlife occurring at the average age of 51 years. The second arises after surgical oophorectomy owing to disease or elective cancer prophylaxis. Finally, primary or premature ovarian insufficiency is characterized by menopause occurring before age 40, often of undetermined etiology, but at times linked with genetic mutations, autoimmune syndromes, metabolic conditions, iatrogenic etiologies, and toxic exposures. Each clinical situation presents unique concerns and management challenges. The majority of women with intact ovaries who live to age 51 experience natural menopause, with early menopause <45 years. In the United States, surgical menopause with bilateral oophorectomy occurs in ∼600,000 women per year. The timing and specific clinical indication for oophorectomy alters management. Primary ovarian insufficiency occurs in 1% of women, although recent estimates suggest the prevalence may be increasing. Symptoms of ovarian insufficiency include hot flashes or vasomotor symptoms, mood disorders, sleep disruption, and vaginal/urinary symptoms. Health concerns include bone, cardiovascular, and cognitive health. Management of symptoms and preventive strategies varies depending upon the age, clinical situation, and specific health concerns of each individual. Treatment options for symptom relief include cognitive behavior therapy and hypnosis, nonhormonal prescription therapies, and hormone therapy. Tailoring the therapeutic approach over time in response to age, emerging medical issues, and patient desires constitutes individualized care.

RESUMEN

OBJECTIVES: To assess the value of intraovarian PRP in women with low ovarian reserve. SEARCH STRATEGY: Screening of databases from inception to January 2023 using the keywords related to "Platelet-rich plasma" AND "poor ovarian reserve" OR "ovarian failure". SELECTION CRITERIA: Fourteen studies (1632 participants) were included, 10 included women with POR, 1 included women with POI and 3 included both POR and POI women. DATA COLLECTION AND ANALYSIS: Extracted data included study settings, design, sample size, population characteristics, volume, timing and preparation of PRP administration, and outcome parameters. MAIN RESULTS: AMH level was evaluated in 11 studies (2099 women). The mean difference (MD) was 0.09 with 95% CI of - 0.06, 0.24 (P = 0.25). Antral follicular count level was assessed in 6 studies (1399 women). The MD was 1.73 with 95% CI of 0.81, 2.66 (P < 0.001). The number of oocytes retrieved was evaluated in 7 studies (1413 women). The MD was 1.21 with 95% CI of 0.48, 1.94 (P = 0.001). CONCLUSION: This systematic review found a significant improvement of AFC, the number of retrieved oocytes, the number of cleavage embryos and the cancellation rate in women with POR. TRIAL REGISTRATION: Registration number CRD42022365682.

RESUMEN

Premature ovarian insufficiency (POI) is a condition in which the quantity of follicles and the quality of oocytes gradually decrease. This results in an estrogen secretion disorder and abnormal follicle development, which can lead to related diseases, early onset of menopause, sexual dysfunction, and an increased risk of cardiovascular issues, osteoporosis, and depression, among others. This disease significantly impacts the physical and mental health and overall quality of life of affected women. Factors such as genetic abnormalities, oophorectomy, radiotherapy for malignancy, idiopathic conditions, and an unhealthy lifestyle, including smoking, can accelerate the depletion of the follicular pool and the onset of menopause. Extensive research has been conducted on the detrimental effects of tobacco smoke on the ovaries. This article aims to review the advancements in understanding the impact of tobacco smoke on POI, both in vivo and in vitro. Furthermore, we explore the potential adverse effects of common toxicants found in tobacco smoke, such as polycyclic aromatic hydrocarbons (PAHs), heavy metals like cadmium, alkaloids like nicotine and its major metabolite cotinine, benzo[a]pyrene, and aromatic amines. In addition to discussing the toxicants, this article also reviews the complications associated with POI and the current state of research and application of treatment methods. These findings will contribute to the development of more precise treatments for POI, offering theoretical support for enhancing the long-term quality of life for women affected by this condition.

RESUMEN

BACKGROUND: The ovarian environment of premature ovarian insufficiency (POI) patients exhibits immune dysregulation, which leads to excessive secretion of numerous proinflammatory cytokines that affect ovarian function. An abnormal level of macrophage polarization directly or indirectly inhibits the differentiation of ovarian granulosa cells and steroid hormone production, ultimately leading to POI. Resveratrol, as a health supplement, has been widely recognized for its safety. There is a substantial amount of evidence indicating that resveratrol and its analogs possess significant immune-regulatory functions. It has also been reported that resveratrol can effectively inhibit the progression of POI. However, the underlying immunological and molecular mechanisms through which resveratrol inhibits the progression of POI are still unclear. RESULTS: Our preliminary reports have shown that resveratrol-ßcd, the beta-cyclodextrin complex of resveratrol, significantly enhances the stability of resveratrol. Resveratrol-ßcd could regulate the dysfunctional immune status of macrophages and T cells in the tumor microenvironment. In this study, we treated busulfan and cyclophosphamide (B/C)-treated mice, which were used as a POI model, with resveratrol-ßcd. After resveratrol-ßcd treatment, the levels of IL-6 in the ovaries were significantly increased, and the progression of POI was suppressed. IL-6 activated granulosa cells (GCs) through soluble IL-6R (sIL-6R), promoting autophagy in GCs. Resveratrol-ßcd and IL-6 had a synergistic effect on enhancing autophagy in GCs and promoting E2 secretion. CONCLUSIONS: We partially elucidated the immune mechanism by which resveratrol inhibits the progression of POI and the autophagy-regulating function of GCs. This provides a theoretical basis for using resveratrol to prevent POI in future studies and clinical guidance.

RESUMEN

Premature ovarian insufficiency (POI) is defined as the development of hypergonadotropic hypogonadism before the age of 40 with definitive treatment being absent. In the current study, we aim to compare the efficacy of the cell sheet method with an intravenous (IV) application of adipose-derived mesenchymal stem cells (AdMSCs) to the POI with an animal model. In the current prospective study, 6-to-8-week-old Sprague Dawley rats were generated four groups: (i) a control group in which only PBS was administered; (ii) an only-POI group generated by cyclophosphamide; (iii) a POI group treated by way of IV AdMSCs; and (iv) a POI group treated by way of the cell sheet method. Twenty-eight days after an oophorectomy was performed, intracardiac blood was taken. Follicle count, immunohistochemical examination for GDF9, BMP15, and TUNEL were conducted, gene expressions of GDF9 and BMP15 were examined, and E2 was measured in the serum samples. With hematoxylin-eosin, in the third group, multi oocytes follicles were the most remarkable finding. In the fourth group, most of the follicles presented normal morphology. GDF9 involvement was similar between the first and fourth groups. BMP-15 immunoreactivity, in contrast to fourth group, was weak in all stages in the second and third groups. The current attempt represents a pioneer study in the literature in which a cell sheet method is used for the first time in a POI model. These results suggest that the cell sheet method may be a feasible and efficient method for the stem cell treatment of models with POI and could be a new treatment approach in POI.

RESUMEN

BACKGROUND: Premature ovarian insufficiency (POI) is a relatively common gynecologic endocrine disorder, which is hypogonadism associated with amenorrhea, increased levels of gonadotropins, and hypoestrogenism. POI resulting from ovarian autoimmunity is a poorly understood clinical condition lacking effective treatments. This study is aimed to investigate the therapeutic effect of mesenchymal stem cells (MSCs) on autoimmune premature ovarian insufficiency. METHODS: In this study, in vivo and in vitro experiments were conducted to clarify the therapeutic effects and possible mechanisms of human bone marrow-derived MSCs (hBMSCs) on autoimmune POI, and to provide an experimental evidence for the treatment of autoimmune POI by hBMSCs. Noteworthy, in this study, we used interferon-gamma (IFN-γ) to induce autoimmune inflammation in human granulosa cell line KGN, simulating the pathophysiological changes of granulosa cells in autoimmune POI, and therefore sought to establish an in vitro cell model of autoimmune POI, which is still lacking in experimental methodology. RESULTS: And we found that, in vitro, co-culture of hBMSCs could promote granulosa cell proliferation, inhibit apoptosis, improve hormone synthesis capacity, and reduce the occurrence of pyroptosis; and in vivo, hBMSCs resulted in improved estrous cycle disorders in autoimmune POI mice, increased serum estradiol, decreased follicle-stimulating hormone, improved ovarian morphology, increased number of primordial and primary follicles, decreased number of atretic follicles, and decreased ovarian granulosa cell apoptosis. CONCLUSIONS: hBMSCs have therapeutic effects on autoimmune POI both in vitro and in vivo.
