Therapeutic Potential of Herbal Compounds in Curing Dysmenorrhea Naturally: A Review

Dysmenorrhea being an effect of uterine contractions in the endometrium is a consequential health concern that may hamper a woman quality of life and disrupt everyday activities. It is described as pain throughout the menstrual cycle which is one of the most prominent causes of pelvic pain in women. Traditional medicine and Ayurveda has for centuries stipulated and employed herbs to treat a variety of illnesses. These herbs contain various bioactive compounds that can be exploited to cure serious health complications of human body. The Purpose of this manuscript is to review every aspect of the menstrual cycle and its mechanism, as well as the application of various conventional treatments and herbal remedies. Numerous scientific studies have been carried out over the past several decades with the ultimate objective of preserving the traditional knowledge of medicinal herbs employed in food and medicine. Herbals like ginger, chamomile, fennel, saffron, onion, nimm primary compounds include Gingerols, terpenoids, flavonoids, coumarins, phyto-molecules, thiosulfanates that possess anti-inflammatory, anti-tumor activities, anti-hyperglycemia, and analgesic properties, which can lower the pain during dysmenorrhea. Literature was searched and data was collected related to herbs from different sources like Pubmed, Google scholar, Science direct. Despite many studies and research, there are many factors that need more information related to herbal medicines and it is necessary to acquire more knowledge about the pertinent hormonal balance induced by herbal remedies.

Association between fatty acids and female infertility: dual evidence from a cross-sectional study and Mendelian randomization analysis

Background: Infertility poses a considerable threat to female reproductive health on a global scale. Dietary pattern, as a modifiable lifestyle factor, is frequently recommended as an important intervention for infertility-related diseases. Fatty acids play a crucial role in maintaining the health of the female reproductive system. However, the available evidence on the specific relationship between various types of fatty acids and infertility remains insufficient and controversial. Methods: Initially, a cross-sectional study was conducted utilizing the National Health and Nutrition Examination Survey (NHANES) database to collect data from women aged 18-45 years who met the inclusion criteria across the 2013-2020 cycles. Infertility was defined based on information gleaned from reproductive questionnaires. Fatty acid intake was determined by analyzing two 24 hour dietary recall interviews. Weighted logistic regression and weighted restricted cubic spline (RCS) analyses, incorporating covariate adjustments, were employed to preliminarily delineate the association between various types of fatty acids and proportions of fatty acid intake and female infertility risk. Model performance evaluation was carried out through receiver operating characteristic (ROC) curve analysis, complemented by the utilization of a nomogram diagram to gauge the infertility risk attributed to covariates. Genetic instrumental variables pertinent to diverse fatty acid profiles and female infertility were sourced from genome-wide association studies (GWAS). Mendelian randomization (MR), multivariable MR (MVMR) and reverse MR analyses were subsequently used to ascertain causality and reverse causality between distinct fatty acids and infertility, concurrently assessing for heterogeneity and horizontal pleiotropy. Results: In our NHANES analysis, a total of 3159 women were enrolled in the study, with a self-reported infertility prevalence of 11.49%. Infertile women exhibited significantly elevated intake of total omega-6 and omega-6/total fatty acids (TFA) compared to the controls. Weighted logistic regression models confirmed positive correlations between total omega-6 (continuous) and omega-6/TFA (categorical) and infertility risk, while omega-3 (continuous) intake demonstrated a negative correlation. Model 2, post rigorous multivariate covariate adjustment, showed improved predictive performance according to ROC curve analysis. Subgroup analysis suggested that the positive correlation between omega-6/TFA (continuous) and female infertility risk was not affected by stratification. Total omega-6 (continuous) emerged as a risk factor for infertile women aged 18-34 years. However, total saturated fatty acids (TSFAs, continuous), total omega-3 (continuous) and total polyunsaturated fatty acids (PUFAs, categorical) were protective factors only in the infertile women with a BMI ≥ 25 kg m-2. The positive associations between total omega-6 (Q4) and omega-6/TFA (continuous and Q3-Q4) and infertility risk were consistent across all BMI subgroups. MR analysis employing inverse variance weighted (IVW) as the primary method and Bonferroni correction revealed that genetically predicted TSFAs, monounsaturated fatty acids (MUFAs), omega-6 and MUFA/TFA were positively associated with female infertility risk, whereas PUFA/TFA showed a negative association. Importantly, the positive associations between MUFAs and omega-6 and infertility risk remained robust even after adjusting for potential confounders using MVMR analyses. Reverse MR analysis did not provide any evidence for reverse causality. The MR-Egger regression intercept and Cochran's Q test did not detect any heterogeneity or horizontal pleiotropy. Conclusions: This study presents compelling evidence to substantiate the link between diverse fatty acids, particularly omega-6 PUFAs, and the risk of female infertility. However, to fully comprehend the potential mechanisms and impact of distinct fatty acids and their compositional ratios on female infertility, extensive future research spanning fundamental and large-scale clinical inquiries is imperative.

The Influence of Metabolic Factors and Diet on Fertility

Infertility is a disease globally affecting 20-30% of the reproductive age female population. However, in up to 50% on recorded cases, problems with infertility are ascribed to men; therefore, it is important to popularize healthy eating also in this group. During the last decade, it has been observed that society's lifestyle changed drastically: reduced energy expenditure in physical activity per day, increased consumption of hypercaloric and high-glycemic-index foods with high content of trans fats, and reduced consumption of dietary fiber, which negatively affects fertility. Increasing evidence points to a link between diet and fertility. It is becoming clear that well-planned nutrition can also contribute to the effectiveness of ART. The low-GI plant-based diet appears to have a positive effect, especially when it is based on Mediterranean dietary patterns: rich in antioxidants, vegetable protein, fiber, MUFA fatty acids, omega-3, vitamins, and minerals. Importantly, this diet has been shown to protect against chronic diseases associated with oxidative stress, which also translates into pregnancy success. As lifestyle and nutrition seem to be important factors affecting fertility, it is worth expanding knowledge in this regard among couples trying to conceive a child.

Evaluation of Intrafollicular Syndecan 1, Glypican 3, and Spermidine Levels in Women with Diminished Ovarian Reserve

We aimed to evaluate the levels of Spermidine, Syndecan 1, and Glypican 3 (GPC3) in the follicle fluid of women with diminished ovarian reserve (DOR) and to examine the relationship of these markers with the number of embryos and clinical pregnancy. A total of 27 women with DOR and 34 women with normal ovarian reserve who underwent in vitro fertilization procedure were included in this prospectively designed study. Spermidine, Syndecan 1, and GPC3 levels were studied in the follicle fluid samples taken from the women at the time of oocyte retrieval by ELISA method, and their relations with the cycle outcomes were examined. The mean age was found as 38.1 ± 7.4 years in the DOR group and 35.1 ± 5.2 years in the control group (p = 0.027). When adjusted for age and body mass index, while the median Spermidine level was significantly higher (p < 0.001), both Syndecan 1 (p < 0.001) and GPC3 (p = 0.006) were significantly lower in the DOR group compared with control group. The cut-off value of Spermidine for clinical pregnancy prediction was found as 74.08 ng/mL with 78.9% sensitivity and 57.1% specificity [OR: 5 (95% CI: 1.4-17.6); AUC: 0.621; p = 0.138], while it was 0.96 ng/mL with 84.2% sensitivity and 59.5% specificity [OR: 7.8 (95% CI: 2-31.1); AUC: 0.701; p = 0.004] for GP3 and 1.15 ng/mL with 78.9 sensitivity and 57.1% specificity [OR: 5 (95% CI: 1.4-17.6); AUC: 0.680; p = 0.009] for Syndecan 1. Intrafollicular spermidine, Syndecan 1, and GPC3 levels may have a role in ovarian aging. Further randomized controlled studies in a larger population are needed for the relationship of these markers with cycle and pregnancy outcomes.

The Influence of Diet on Ovulation Disorders in Women—A Narrative Review

Female infertility is commonly due to ovulation disorders. They are mostly related to polycystic ovary syndrome, which is currently viewed as one of the most common endocrine disorders in women of reproductive age. Ovulation-related female fertility is influenced by multiple factors which may include: age, smoking cigarettes, stress, use of psychoactive substances, and physical activity. Moreover, diet-related factors play an important role in the regulation of ovulation. Dietary components that exert a positive influence on ovulation include: carbohydrate products with low glycemic index, plant protein, monounsaturated and polyunsaturated fatty acids, folic acid, vitamin D, antioxidants, and iron. A diet based on the structure of the Mediterranean diet also seems beneficial. Components that have a negative influence mostly include high glycemic index carbohydrates, large amounts of animal protein, saturated fatty acids, and trans fatty acids, which are typically found in the Western model of nutrition. Due to the paucity of studies that presented a direct link between nutrition and the risk of anovulatory infertility, this study aimed to summarize the most recent research on the influence of dietary factors on ovulation disorders and indicate the possibilities of future research.

A randomised trial examining inflammatory signaling in acutely induced hyperinsulinemia and hyperlipidemia in normal weight women-the reprometabolic syndrome

CONTEXT

Obesity, is a state of chronic inflammation, characterized by elevated lipids, insulin resistance and relative hypogonadotropic hypogonadism. We have defined the accompanying decreased Luteinizing Hormone (LH), Follicle-Stimulating Hormone (FSH), ovarian steroids and reduced pituitary response to Gonadotropin-releasing Hormone (GnRH) as Reprometabolic syndrome, a phenotype that can be induced in healthy normal weight women (NWW) by acute infusion of free fatty acids and insulin.

OBJECTIVE

To identify potential mediators of insulin and lipid-related reproductive endocrine dysfunction.

DESIGN, SETTING, PARTICIPANTS

Secondary analysis of crossover study of eumenorrheic reproductive aged women of normal Body Mass Index (BMI) (<25 kg/m2) at an academic medical center.

INTERVENTION

Participants underwent 6-hour infusions of either saline/heparin or insulin plus fatty acids (Intralipid plus heparin), in the early follicular phase of sequential menstrual cycles, in random order. Euglycemia was maintained by glucose infusion. Frequent blood samples were obtained.

MAIN OUTCOME MEASURES

Pooled serum from each woman was analyzed for cytokines, interleukins, chemokines, adipokines, Fibroblast Growth Factor-21 (FGF-21) and markers of endoplasmic reticulum (ER) stress (CHOP and GRP78). Wilcoxon signed-rank tests were used to compare results across experimental conditions.

RESULTS

Except for Macrophage Inflammatory Protein-1β (MIP-1β), no significant differences were observed in serum levels of any of the inflammatory signaling or ER stress markers tested.

CONCLUSION

Acute infusion of lipid and insulin, to mimic the metabolic syndrome of obesity, was not associated with an increase in inflammatory markers. These results imply that the endocrine disruption and adverse reproductive outcomes of obesity are not a consequence of the ambient inflammatory environment but may be mediated by direct lipotoxic effects on the hypothalamic-pituitary-ovarian (HPO) axis.
