Metformin as a Potential Treatment Option for Endometriosis. Cancers (Basel) 2022; 14:cancers14030577. [PMID: 35158846 PMCID: PMC8833654 DOI: 10.3390/cancers14030577] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 01/07/2022] [Accepted: 01/21/2022] [Indexed: 02/07/2023] Open
Abstract
Endometriosis is a common disease in women of reproductive age, and its pathogenesis seems to be largely affected by hormone imbalance, inflammation, oxidative stress, and autophagy dysregulation. These pathophysiological disturbances interact with one another through mechanisms that are still awaiting elucidation. The aim of this article is to present current knowledge regarding the possibilities of using metformin in the pharmacological treatment of endometriosis. Metformin is an insulin sensitizer widely used for the treatment of type 2 diabetes mellitus. The pleiotropic effects of metformin are mainly exerted through the activation of AMP-activated protein kinase, which is the key cellular energy homeostasis regulator that inhibits mTOR, a major autophagy suppressor. Metformin regresses endometriotic implants by increasing the activity of superoxide dismutase. It is also an inhibitor of metalloproteinase-2, decreasing the levels of the vascular endothelial growth factor and matrix metalloproteinase-9 in animal studies. In endometriosis, metformin might modify the stroma-epithelium communication via Wnt2/β-catenin. With its unique therapeutic mechanisms and no serious side effects, metformin seems to be a helpful anti-inflammatory and anti-proliferative agent in the treatment of endometriosis. It could be a missing link for the successful treatment of this chronic disease.

Dietary Supplements for Female Infertility: A Critical Review of Their Composition. Nutrients 2021; 13:nu13103552. [PMID: 34684554 PMCID: PMC8541636 DOI: 10.3390/nu13103552] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Accepted: 10/06/2021] [Indexed: 12/25/2022] Open
Abstract
Infertility is the condition of about 15% of couples that cannot get a conception after one year of unprotected sexual intercourse. In females, the reduced reproductive capacity underlies the most varied causes. Dietary supplements (DS) might be used to improve the pregnancy rate and a wide range of DS are proposed today to support female fertility. Although many authors demonstrated the positive effect of some of these products, the real efficacy of this approach is still debated. In order to evaluate the potential efficacy of DS for female infertility, we analysed the products marketed in Italy, using an original approach. A review of literature was performed to evaluate the effect of nutraceuticals on various female reproductive outcomes and to detect the minimal effective daily dose (mED) able to improve at least one of these. Thereafter, we conceived a formula to classify the expected efficacy of each DS. Each DS was scored and included into three classes of expected efficacy: higher, lower, and none. Ten out of 24 supplements (41.7%) resulted in the higher and 8 (34.3%) in the lower efficacy group, the remaining 6 DS (25.0%) were expected to have no efficacy. DS marketed in Italy are usually blends of many substances that are frequently employed at a negligible dose or without any evidence of efficacy. These findings raise serious doubt about the potential effectiveness of most commercial DS for female infertility.

Abstract
Endometriosis is a benign gynecological disease which symptoms can provide a severe impact on patient's quality of life with subsequent impact on psychological well-being. Different therapeutic strategies are available to treat this disease, such as surgery, hormonal therapies, and nonsteroidal anti-inflammatory drugs. Nevertheless, the efficacy of conventional medical treatments is limited or intermittent in most of the patients due to the associated side effects. Therefore, a woman with endometriosis often search for additional and alternative options, and phytotherapy might be a promising alternative and complementary strategy. Different medicinal plants, multicomponent herbal preparations, and phytochemicals were investigated for pharmacological proprieties in endometriosis therapy. In most of the cases, the effect on endometriosis was related to phenolic compounds, such as flavonoids and phenolic acids reporting anti-inflammatory, proapoptotic, antioxidant, and immunomodulatory functions. Moreover, some phytochemicals have been related to a strong phytoestrogenic effect modulating the estrogen activity. Although promising, available evidence is based on in vitro and animal models of endometriosis with a limited number of well-performed clinical studies. There are almost none randomized control trials in this area. Therefore, properly constructed clinical trials are mandatory to achieve more conclusive results about the promising role of phytotherapy in the management of endometriosis.

Abstract
Polycystic ovary syndrome (PCOS) is one of the most common causes of subfertility, and it is characterized by hormonal dysregulation like insulin resistance. Various measures have been taken in the past to overcome this insulin resistance to improve fertility treatment outcomes. The current paper aims to review and compare the existing studies and literature to assess the impact of myo-inositol (MI) on oocyte and embryo quality in assisted reproductive technology (ARTs). We thoroughly searched the PubMed and Google Scholar databases by using the keywords "PCOS, polycystic ovarian syndrome, inositol, oocyte quality, embryo quality, assisted conception, ART, IVF, and in vitro fertilization." Nine articles were finalized for review in this paper. Many of the reviewed studies have shown a trend toward the improvement of embryo quality in women with PCOS after MI supplementation; however, there is a lack of statistically significant evidence to support the use of MI in enhancing the quality of oocyte and/or embryo. Clear evidence regarding the role of MI in enhancing the quality of oocyte and embryo in PCOS is limited. A well-controlled, large, randomized controlled trial is required to definitively accept or refute its role.

Abstract
The incidence of metabolic syndrome (MetS), type II diabetes (T2D) and polycystic ovarian syndrome (PCOS) has been progressively increasing. Insulin resistance (InsR) seems to play a key role in a majority of phenotypes of these conditions, altering metabolic homeostasis, within muscle, liver, adipose and other tissues. Hyperinsulinemia is often associated with InsR and causes hormonal imbalances especially within ovaries and adrenals. Inositol is a polyalcohol, naturally occurring as nine stereoisomers, including D-chiro-inositol (DCI) and myo-inositol (MI), which have prominent roles in the metabolism of glucose and free fatty acids. MI and DCI have been classified as insulin-sensitizers and seem to adequately counteract several InsR-related metabolic alterations with a safe nutraceutical profile. Based on our analysis of selected studies that investigated MI and/or DCI, we conclude that supplementation with MI and/or DCI complement each other in their metabolic actions and act in synergy with other insulin sensitizing drugs and/or nutraceuticals. Nevertheless, considering the possible severe bias due to different methodologies across published studies, we conclude that there is a need for further studies on larger cohorts and with greater statistical power. These should further clarify outcomes and suitable therapeutic dosages of MI and DCI, possibly based on each patient's clinical status.

Abstract
Infertility due to polycystic ovarian syndrome (PCOS) is a worldwide problem that is increasing at alarming rates. Insulin resistance, the prime factor of PCOS, induces comorbid metabolic syndrome as well. Durian (Durio zibenthinus Linn), a fruit of Southeast Asia, is used as a natural supplement in healthy diets. This paper is a short literature review that examines the fruit's effects against various components of metabolic syndrome and its fertility-enhancing properties in PCOS. Various published literature was reviewed to learn of the anti-inflammatory, anti-oxidant, anti-obesity, anticholesterol, and antihypoglycaemic nature of the fruit. The literature search was done using PubMed, Google Scholar and library databases. The keywords used were polycystic ovarian syndrome, infertility, metabolic syndrome and Durian zibenthinus Linn. Reviewed studies showed that the fruit is effective against various components of metabolic syndrome, but the mechanisms of action against anovulation and menstrual disturbances in PCOS have yet to be studied. The traditional use of durian as a fertility-enhancing agent needs to be validated scientifically by isolating its various components and ascertaining its fertility enhancing properties.

Acute immunomodulatory changes during controlled ovarian stimulation: evidence from the first trial investigating the short-term effects of estradiol on biomarkers and B cells involved in autoimmunity. J Assist Reprod Genet 2015; 32:1765-72.

Abstract
PURPOSE The aim of the present study was to evaluate the in vivo immunomodulatory effects of an acute short-term estradiol (E(2)) increase on serum levels of B cell-activating factor (BAFF), immunoglobulins (Ig), anti-nuclear antibodies (ANA), and the peripheral B cell phenotype. METHODS We conducted, at the Infertility Center of the University of Padua, a prospective case-control study on a cohort of infertile normo-responder women (group-A, 63 patients) undergoing controlled ovarian stimulation (COS) compared with an age-matched cohort of normo-ovulatory healthy women (group-B, 39 patients). Three serial blood sample assays were conducted in both groups, at T0, hypothalamic suppression; T1, ovulation induction; and T2, βhCG test in group A, and at T0, 2nd day; T1, 14th day; and T2, 21st day of cycle in group B, and serum levels of E(2) and BAFF, BAFF/E(2) ratio, circulating IgM, IgG, and IgA, ANA titer, and peripheral B cell phenotype were measured. We compared group-A versus group-B in terms of absolute and E(2) normalized values of BAFF at baseline (T0) to verify for possible differences between healthy and infertile women, at T1 to verify for possible differences occurring after spontaneous ovulation versus COS, and at T2 to evaluate differences in serum BAFF levels between pregnant versus non-pregnant patients (considering only group-A) and between non-pregnant women after spontaneous versus COS cycles (group-B versus group-A). In group-A, we also evaluated IgM, IgG, IgA levels, ANA titer, and peripheral B cell phenotype at T0 versus T1 versus T2. RESULTS With the exception of E(2) levels at T1 (as expected), no significant differences were found between the two groups for all outcome measures. In group-A, BAFF at T0 positively correlated with IgM levels; marginal zone CD19+/CD27+/IgD+ memory B cell compartment tended to be expanded at T1 when compared with T0. CONCLUSIONS Despite several mechanistic and clinical studies supporting a stimulatory role of E(2) on autoimmunity, the acute increase of E(2) during COS for infertility treatment does not seem to have a major impact on the immune system.
