    ABSTRACT: Mammalian fertilization is a highly programmed process by which sperm and egg unite to form a zygote, a cell with somatic chromosome numbers. To fertilize an egg, the capacitated (acrosome-intact) spermatozoa recognize and bind to the egg's extracellular glycocalyx coat, the zona pellucida (ZP). The tight and irreversible binding of the opposite gametes in the mouse and many other species studied, including man, results in the opening of Ca2+ channels on sperm plasma membrane (PM) and influx of Ca2+. The transient rise in Ca2+ and other second messengers, such as cAMP and IP3, initiates a cascade of signaling events that elevate sperm pH and triggers the fusion of the sperm PM and underlying outer acrosomal membrane at multiple sites (induction of the acrosomal reaction). The fusion of the two membranes results in the exocytosis of acrosomal contents at the site of sperm-egg adhesion. The hydrolytic action of the acrosomal enzymes (glycohydrolases, proteinases, esterases, sulfatases etc), released at the site of sperm-egg adhesion, along with the enhanced thrust generated by the hyperactivated spermatozoon, are important factors that regulate the penetration of the ZP and the fusion of the acrosome-reacted spermatozoon with the egg. Evidence accumulated over the past two decades strongly suggests that glycan units of the ZP have a significant role in the recognition and adhesion of the opposite gametes and induction of the AR. In this review article, we intend to highlight well programmed molecular events that results in the sperm-egg adhesion and fertilization. Our intention is also to discuss the increasing controversy on the role of ZP glycan chains in sperm-egg interactions.

    ABSTRACT: Postmenopausal osteoporosis is a silent systemic progressive disease characterised by a decrease in bone mass per unit volume. This condition compromises the physical strength of the skeleton and increases the susceptibility to fractures on minor trauma. The imbalance between bone formation and bone resorption is known to be responsible for postmenopausal bone loss. Estrogen deficiency contributes to bone loss by increasing the production of pro-inflammatory cytokines by bone marrow and bone cells. Clinical and molecular evidence indicates that estrogen-regulated cytokines exert regulatory effects on bone turnover implicating their role as being the primary mediators of the accelerated bone loss at menopause. The current perspective on the role and interaction of cytokines such as IL-1, IL-4, IL-6, IL-17, TNF, IFN-γ and TGF-β in bone loss linked with estrogen deficiency is reviewed. Current treatment options and emerging drug therapies in the management of postmenopausal osteoporosis are also evaluated.

    ABSTRACT: Today, 88% of pregnancies has a physiological course during which just basic care, while in 12% of cases there is a high-risk pregnancy that requires additional assistance and specific. The approach that should be used is that of supervision in all pregnant women considering their potential to have a normal pregnancy until there is no clear evidence to the contrary. Pregnancy is considered at risk if there are medical conditions that may affect maternal or fetal health or life of the mother, fetus or both. Among the risk factors for pregnancy there is first the woman's age, in fact the increase in high-risk pregnancies in the last 20 years is attributable to the increase in the average age of women who face pregnancy. In addition, the diet is very important during pregnancy and diabetes or autoimmune diseases often lead to the failure of a pregnancy. Risk factors for pregnancy, also, are the complications that occur during its course as hypertension during pregnancy, and infectious diseases. Fears and anxieties typical of a high-risk pregnancy prevent the couple to live happily in the months of gestation. Effective communication, control and early detection are important tools that doctors must be able to ensure that women in order to plan the best treatment strategies and to minimize the risks of maternal and / or fetal.

    ABSTRACT: The estimated incidence of cancer diagnosed in pregnant women in developed societies is 1:1000 pregnancies. The most common cancers associated with pregnancy are gynecological, breast, hematological, and skin. A multidisciplinary care team is required. Various treatment modalities are used, including surgical intervention, chemotherapy and radiological. The management of the malignant condition should be standardized, similarly to management offered without pregnancy. Hormone therapy and chemotherapy in the first trimester, and radiotherapy are most contra-indicated. The delivery term depends on the date of discovery of cancer, but is beyond 35 weeks of gestation in the majority of cases, to minimize fetal or obstetrical risks. Pregnancy does not have a deleterious effect on the prognosis of cancers generally, but it is often associated with a delay in diagnosis. Malignant disease management and feto-maternal outcome are described in the present review and particular attention is focused on the treatment effects.

    ABSTRACT: The recent epidemiological explosion of diabetes amplified the problems regarding the various complications related to the disease and its complex healthcare management. Among these, those relating to the pregnancy of women with diabetes are highly significant from the point of view of social health, for the consequences of the disease on the unborn child, but also in the mother. It is possible that diabetes exists before pregnancy (pregestational diabetes), but much more often it can appear during pregnancy in women unaware of the disease (gestational diabetes). The mainstay of therapy for diabetes and gestational diabetes resides in diet, therapy with oral hypoglycemic agents or insulin, but the appearance on the market of supplements consisting of substances such as D-chiro-Inositol (DCI) arousing considerable interest, as it seems to be able to help in the glycemic control in this type of disease but, of course, its effectiveness must be proved. The data of our study seem to show that the DCI supplement has a role in the regulation of glucose metabolism and insulin sensitivity, and is able to act on the metabolism of pregnant women at risk of developing gestational diabetes, who probably have a basic alteration of insulin and glucose metabolism. It acts improving insulin sensitivity and reducing the onset of gestational diabetes in pregnant women at risk, decreasing the weight gain and nocturnal hypoglycemia responsible for the attacks of hunger at night. Further studies would be desirable to clarify the mechanism of action of DCI at the cellular level in glucose metabolism during pregnancy, and clinical data must be confirmed with wider studies.

    ABSTRACT: Oxytocin (OT) signalling plays a fundamental role in the mechanisms of parturition. OT is one of the most frequently used drugs in obstetrics, promoting uterine contractions for labor induction and augmentation and to prevent postpartum hemorrhage (PPH). Expression of the oxytocin receptor (OTR) in the human myometrium is tightly regulated during pregnancy and its levels have been shown to peak upon labour onset and to fall sharply in advanced labour and the postpartum period, when the uterus become refractive to OT. However, uterine sensitivity to OT varies between pregnant women, probably reflecting differences in their myometrial OTR expression. Control of OTR expression is mediated by a combination of steroid hormone stimulation, stretch, and inflammation. This review summarises current knowledge regarding the complex regulation of myometrial OTR expression and its associated intracellular signaling pathways.

    ABSTRACT: Among couples unable to conceive without any identifiable cause, 30% are defined as having unexplained infertility. Management depends on duration of infertility and age of female partner. In order to increase pregnancy rate, couples with infertility of unknown origin can undergo ovulation induction and intrauterine insemination. These techniques are able to increase pregnancy rate in case of unexplained infertility. Clomiphene citrate and menopausal or recombinant gonodotropins are the most used drugs to induce ovulation. Aim of the present study was to evaluate the success rate after homologous intrauterine insemination (IUI) combined with clomiphene citrate (CC) stimulation.

    ABSTRACT: Melatonin is one of the main sources of mitochondrial protection and its protective effects are equal or even better if compared with several consecrated antioxidants. Furthermore, the activation of specific melatonin receptors triggers several cellular pathways that improve the oxidoreduction and inflammatory cellular state. The discovery of the melatoninergic machinery in placental cells was the first step to understand the effects of this indoleamine during pregnancy. In critical points of pregnancy, melatonin has been pointed as a protagonist and its beneficial effects have been shown as essential for the control of trophoblastic function and development. On the contrary of the plasmatic melatonin (produced in pineal gland), placental melatonin does not vary according to the circadian cycle and acts as an autocrine, paracrine, intracrine, and endocrine hormone. The important effects of melatonin in placenta have been demonstrated in the physiopathology of pre-eclampsia with alterations in the levels of melatonin and in the expression of its receptors and synthetizing enzymes. Some authors suggested melatonin as a biomarker of pre-eclampsia and as a possible treatment for this disease and other obstetric pathologies associated with placental defect and increases in oxidative stress. This review will approach the beneficial effects of melatonin on placenta homeostasis and consequently on pregnancy and fetal health.

    ABSTRACT: Unexplained infertility affects 30% of infertile couples. Management depends on duration of infertility and age of female partner. Ovulation induction, together with intrauterine insemination, is commonly offered to couples with infertility of unknown origin. Intrauterine insemination gained its popularity because it is simple, non-invasive and cost-effective technique. The association with pharmacological stimulation is suitable to induce follicular maturation. The most used drugs to induce ovulation are clomiphene citrate and menopausal or recombinant gonodotropins. The aim of this paper was to evaluate the success rate after homologous intrauterine insemination (IUI) combined with menopausal gonadotropins stimulation.

    ABSTRACT: The putative role and use of dehydroepiandrosterone (DHEA) as replacement therapy for menopausal women has been under consideration during the latest years. DHEA is one of the main adrenal hormones that progressively reduces its plasmatic levels from the beginning of ageing. This phenomenon implies not only the reduction of the plasmatic androgens but also the decrease of a peculiar category of hormones, named neurosteroids, in particular one: allopregnanolone. This review aims to elucidate the peculiar aspects of DHEA administration and its putative use as substitutive/integrative hormonal treatment alone or in combination with the traditional hormone replacement therapy.

    ABSTRACT: Stress urinary incontinence is the most common form of urinary incontinence, occurring in pure or mixed forms in nearly 80% of women with incontinence. Hypoestrogenism may cause female incontinence and low bone mineral density, together. So, we investigated the relationship between stress urinary incontinence, serum E2 levels and osteoporosis in premenopausal and postmenopausal women.

    ABSTRACT: Pre-eclampsia is a multisystem disorder of pregnancy that affects 5-8% of pregnancies. The pathophysiologic mechanisms that lead to the development of pre-eclampsia are poorly understood. Higher than normal levels of circulating TH17 is observed in preeclamptic women compared to women with normal pregnancy. TH17 cells are a subset of CD4+ T helper cells that are characterized by their secretion of IL-17. Recent studies suggest a role for TH17 cells and IL-17 in the pathophysiology of pre-eclampsia. In this review, we will discuss the known function of TH17 cells and IL-17 in immunity and vascular function. We will then review the role of IL-17 and TH17 cells in normal pregnancy and their association with pre-eclampsia, followed by a discussion of the literature to examine a potential role for IL-17 and TH17 cells in mediating pathophysiology in pre-eclampsia.
