SETTING: Luteinizing hormone (LH) and human chorionic gonadotropin (hCG) act on the same receptor, activating different signal transduction pathways. The role of LH or hCG addition to follicle-stimulating hormone (FSH) as well as menopausal…
Introduction: Several pollutants have been implicated in the etiopathogenesis of endometriosis. However, recent epidemiological studies have yielded contrasting results. With the aim to address the role of environmental contaminants on the …
BACKGROUND: Several studies have shown that exposure to benzene is associated to menstrual disorders, miscarriages and other disorders of the reproductive system. We performed an observational prospective pilot study to evaluate if levels o…
BACKGROUND: Hypogonadotropic hypogonadal women are characterized by ovarian functionality deficiency, caused by low concentrations of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). To recover reproduction functionality, re…
BACKGROUND: V-betaLH is a common genetic variant of LH caused by two polymorphic base changes in the beta subunit gene, altering the amino acid sequence (Trp8Arg and Ile15Thr). In a previous-preliminary trial performed in women undergoing I…
Variability in the subfertile patient population excludes the possibility of a single approach to controlled ovarian stimulation (COS) covering all the requirements of a patient. Modern technology has led to the development of new drugs, tr…
BACKGROUND: Women have been able to delay childbearing since effective contraception became available in the 1960s. However, fertility decreases with increasing maternal age. A slow but steady decrease in fertility is observed in women aged…
Some studies have suggested a possible role of leptin, an active cytokine produced by adipocytes, in the pathogenesis of pelvic endometriosis. The present study was designed to assess leptin levels in the peritoneal fluid (PF) of women with…
BackgroundMultifollicular ovarian stimulation (MOS) is widely used in IVF and the compliance to treatment is deeply influenced by the tolerability of the medication(s) used and by the ease of self-administration. This prospective, controlle…
An adult Caucasian female developed a previously unreported association of pelvic endometriosis (PE) with the triad of alopecia universalis (AU), autoimmune thyroiditis (AT) and multiple sclerosis (MS). Molecular human leukocyte antigen (HL…
Initially described as an antiobesity hormone, leptin has subsequently been shown also to influence hematopoiesis, thermogenesis, reproduction, angiogenesis, and immune homeostasis. Leptin links nutritional status and proinflammatory T help…
Endometriosis is a chronic inflammatory disease, characterized by implantation and growth of endometrial tissue outside the uterine cavity. This disabling condition is considered one of the most frequent diseases in gynecology, affecting 15…
This study was designed to measure leptin concentrations in the peritoneal fluid (PF) of women with different aspects of pelvic endometriosis. Among 36 consecutive women undergoing laparoscopy, nine were diagnosed as having minimal-mild end…
Pelvic endometriosis is an immune-related chronic inflammatory disease, characterized by ectopic implants of endometrium in the peritoneal cavity and associated with increased secretion of proinflammatory cytokines and neoangiogenesis. Lept…
Serum concentrations of soluble human leukocyte class I antigens (sHLA-I) and of the intercellular adhesion molecule-1 (sICAM-1) are increased in the early inflammatory stages of several immune-related diseases. These soluble molecules also…
