The kisspeptin is a neuropeptide to play physiological roles in regulating gonadotropin-releasing hormone secretion in the hypothalamus. In human plasma, the kisspeptin concentration is measured, but gonadotropin-releasing hormone is not. This study aims to understand the physiological roles of the circulating kisspeptin in lactational amenorrhea in humans because prolactin reduces the kisspeptin expression and luteinizing hormone secretion resulting in anovulations in rodent brains. Plasma kisspeptin levels were measured in 11 subjects in lactational amenorrhea and in four cases with pathological amenorrhea by different etiologies for comparison using the enzyme immunoassay specific for human kisspeptin...

Postmenopausal osteoporosis (PO) has a strong genetic component. Presently, the published evidence on the association between the main single-nucleotide polymorphisms (SNPs) of the receptor activator of nuclear factor-kb ligand (RANKL), osteoprotegerin (OPG) and vitamin D receptor (VDR) and bone mass density (BMD) are scarce, mostly considering Italian population. This study sought to determine whether OPG (rs2073618), RANKL (rs9525641) and the VDR (rs2228570) SNPs were associated with BMD in a sample of 139 North-Italian postmenopausal women...

We describe successful controlled ovarian stimulation (COS) and the first known IVF pregnancy in a trisomy X carrier with associated hypogonadotropic hypogonadism (HH) linked to a chromosome 4 double mutation in the allele of the Gonadotropins Releasing Hormone receptor (GnRHr) gene. Previous administration of low dose of gonadotropins, as recommended in patients with HH, led to poor follicular recruitment. Since trisomy X is a risk factor for diminished ovarian reserve (DOR) and premature ovarian insufficiency (POI), higher doses of gonadotropins led to better ovarian response...

The aim of this study was to evaluate the influence of body mass index (BMI) and ultrasound-estimated visceral adipose tissue deposits on oocyte quality and pregnancy rate in women undergoing Assisted Reproductive Technology (ART) procedures. The study included 58 women who underwent ART procedures. According to their BMI, the women were divided into normal weight and overweight/obese; an ultrasound evaluation of preperitoneal fat thickness (PFT) was also performed for each patient. The oocyte quality was then assessed, and samples of follicular fluid were collected from each woman, in order to evaluate the intrafollicular concentration of reactive oxygen species (ROS) as markers of oxidative stress and pro-inflammatory cytokines (IL-1β and IL-6) as markers of chronic inflammation...

BACKGROUND: Estrogen has been proved to have positive effects on the brain cognitive function. However, many clinical studies investigating the associations between cognitive functions and circulating estrogen levels in perimenopausal and postmenopausal women demonstrated controversial results. METHOD: Circulating estradiol and follicle stimulating hormone (FSH) levels were obtained from 199 perimenopausal and postmenopausal women (mean age: 49.61 years). The cognitive function has been assessed using the Beijing version of the Montreal Cognitive Assessment...

A large number of evidence supports the role of vitamin D insufficiency in both women and men infertility. However, no studies have evaluated the rate of concordance of vitamin D status between the partners. This finding might open new scenarios in the interpretation of the available data linking vitamin D insufficiency and infertility. In the present cross-sectional study, 103 consecutive infertile couples were recruited between April and May 2014. Both partners concomitantly provided a serum sample for the assessment of 25-hydroxy-vitamin D [25-(OH)-D]...
