Objective: PCOS is the most common endocrinopathy among reproductive age women. Approximately 60% of PCOS women have insulin resistance. While the efficacy of metformin in reducing insulin resistance and decreasing androgen level has been widely validated, there is no agreement on the dose of metformin to be used. Patients and methods: Prospecti...

In the last few years new oral contraceptives have been marketed showing a better safety profile for women. They are the result of important changes made to the old compounds. As far as the estrogenic component, with the aim of decreasing side effects, the dose of ethinyl estradiol has been reduced and synthetic estrogens have been replaced by natu...

La vit. D, o calcitriolo, è stata identificata inizialmente nei primi anni '20 ed ha un ruolo chiave nella regolazione del metabolismo osseo, nell'omeostasi del calcio e del fosforo e nel promuovere la mineralizzazione ossea. Le azioni della vit. D sono mediante tramite un recettore nucleare (VDR), che è espresso in numerosi organi come l'intestino...

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder affecting 5–10% of women of reproductive age. It generally shows with oligo/amenorrhea, anovulatory cycles, clinical o biochemical hirsutism, polycystic ovaries and, in a significant percentage of cases, insulin resistance. PCOS is defined as a multifactorial pathology, determined by...

Background: The female genital apparatus, the urinary tract and the perineal supporting tissues share a common embryological origin, whose differentiation depends on the action of estrogens. In adult women, the progressive decline of the ovarian function, with the ensuing estrogen deprivation, reduces tissue tropism causing urogenital atrophy, whi...

Objective: Polycystic ovary syndrome (PCOS) is the most common endocrinopathy of women of reproductive age and a complex endocrine condition, due to its heterogeneity and uncertainty about its etiology. However, PCOS is also associated with other metabolic abnormalities such as insulin resistance, impaired glucose tolerance, and diabetes. There ar...

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder affecting 5–10 % of women of reproductive age. It generally manifests with oligo/anovulatory cycles, hirsutism and polycystic ovaries, together with a considerable prevalence of insulin resistance. Although the aetiology of the syndrome is not completely understood yet, PCOS is consid...

Objectives This study was designed to measure the beneficial effects of a combination of nutraceutics (NUT; AkP04, Morestril®, Akademy Pharma) containing soy isoflavones (80 mg), dry extract of Angelica sinensis (50 mg), dry extract of Morus alba leaf (200 mg) and magnesium (56.25 mg) in the relief of somatic, psychological, and urogenital symptoms...

Sommario L’infertilità di coppia rappresenta una patologia in aumento e la stimolazione ovarica controllata è un aspetto rilevante in medicina riproduttiva. Lo sviluppo dei follicoli nei vari stadi richiede una comunicazione tra ovocita, cellule della granulosa e della teca attraverso una regolazione paracrina che influisce sulla risposta alle gona...

Background In recent years, several new oral contraceptives have become available. In some ways, they represent an evolution in terms of individualization and compliance on the part of women. The new formulations make it increasingly possible to prescribe a specific hormonal contraceptive on an individual basis. Methods A systematic literature sea...

The onset of vasomotor symptoms in postmenopausal women represents the beginning of a hard period from the emotional point of view which involves some of the most important neurotransmitters. Hot flushes and insomnia associated with a state of anxiety that affect postmenopausal women are included in an index known as the Kupperman Index. The use of...

Background: Insulin resistance is characteristic of patients with metabolic syndrome and it’s more pronounced in overweight patients. In the long term there may be cardiovascular and pressor consequences. Lifestyle and diet changes may partly improve these aspects. The use of insulin-sensitizing drugs such as metformin gives good results, although...

Aim: Polycystic ovary syndrome (PCOS) affects 5-10% of women of childbearing age and manifests itself through oligomenorrhea, anovulation, hirsutism, micro-polycystic ovaries. Insulin resistance is a characteristic of PCOS patients and is more pronounced in obese patients. Insulin resistance and consequent hyperinsulinemia are related to many aspe...

Aim: Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies of the reproductive age in women. PCOS is an endocrine-metabolic disorder characterized by insulin resistance. Aim of the study was to evaluate the efficacy of natural substances such as inositol and glucomannan, and their combination in reducing glucose levels and im...

Purpose The purpose of this study was to evaluate the oxidative stress status (OS) of follicular fluid (FF) and the oocyte quality in women with polycystic ovary syndrome (PCOS) undergoing different ovarian stimulation protocols. Methods FF samples were collected after gonadotropin administration in association or not with metformin or D-chiro-i...

Aim: Polycystic ovary syndrome (PCOS) is a multifactorial pathology affecting 7-10% of the female population. Usually occurs with oligo/amenorrhea, anovulation, hirsutism, polycystic ovaries. Hyperinsulinemia associated with insulin resistance has been causally linked to all features of the syndrome. It has been demonstrated that by reducing hyper...

Aim: Recent studies on the pathophysiology of infertility have shown that oxidative stress (OS) can be one of the causal factors. The OS is, by definition, an imbalance between the production of reactive oxygen species (ROS) and antioxidant defense systems. It seems that oxidative stress plays an important role in almost all phases of human reprod...
