In women, single nucleotide polymorphisms (SNP) of the FSH receptor (FSHR) gene influence FSH concentrations and the sensitivity of the FSHR to FSH in vivo. In contrast, the significance of FSHR R gene SNP in the male is poorly understood. To this aim, the possible role of three FSHR SNP was evaluated in male infertility. SNP in exon 10 (codon 307 and 680)(More)
The development of testicular germ cell tumour (TGCT) is believed to be under endocrine control but definitive proofs are lacking. Follicle stimulating hormone (FSH) levels are increased in numerous conditions associated with increased risk of TGCT and single nucleotide polymorphisms (SNPs) in the FSH receptor (FSHR) gene influence the sensitivity of the(More)
In the last years, follice-stimulating hormone (FSH) receptor (FSHR) gene polymorphisms have been studied as potential risk factors for spermatogenetic failure. In this study, we have evaluated the response of FSH treatment in terms of sperm production on the basis of Ala307Thr-Asn680Ser polymorphisms in the FSHR gene in a group of oligozoospermic subjects(More)
INTRODUCTION Premature ejaculation (PE) is defined as the inability of men to control ejaculation and it is the most prevalent male sexual dysfunction. The neurobiogenesis of ejaculation is very complex and involves the serotoninergic (5-hydroxytryptamine [5-HT]) system. A genetic etiology of PE in humans was stated accounting for around 30%. Recently,(More)
Epidemiological data suggest an association and a common pathogenetic link between male infertility and testicular germ cell tumor (TGCT) development. Genome-wide studies identified that TGCT susceptibility is associated with KITLG (c-KIT ligand), which regulates the formation of primordial germ cells, from which TGCT is believed to arise and(More)
It is generally assumed that the development of testicular germ cell tumor (TGCT) is under endocrine control. In particular, unbalanced androgen/estrogen levels and/or activity are believed to represent the key events for TGCT development and progression. Furthermore, recent evidence has suggested a strong genetic component for TGCT. In this study, we(More)
Primary aldosteronism (PA) is the most common endocrine form of hypertension and may carry an increased risk of atrial flutter or fibrillation (AFF). The primary goal of this multicentre cohort study is thus to prospectively establish the prevalence of PA in consecutive hypertensive patients referred for lone (non-valvular), paroxysmal or permanent AFF.(More)
Periodontitis (PO) is a multifactorial disease affecting about 10% to 20% of the general population. Several studies have suggested that part of the clinical variability in PO might be explained by genetic factors. Among the candidate genes for PO, IL1 gene polymorphisms have been broadly investigated, with variable results, for their relationship with the(More)
