Introduction: Klinefelter syndrome (KS) is characterised by the presence of at least one extra X chromosome and represents the most common chromosomal aberration in men. Apart from infertility, the clinical spectrum of KS is variable and often not directly related to hypogonadism, whose expression is also not unpredictable. Several genetic mechanisms may explain the clinical features and variability of the phenotype in KS. In particular, gene-dosage effects and the parental or...

Introduction: Polymorphisms in the gene for FSH receptor (FSHR) and FSH β subunit (FSHB) might modulate FSH levels and represent genetic markers for a pharmacogenetic approach to male infertility treatment. rs6166 (c.2039 A>G, Asn680Ser) and rs1394205 (c.−29 G>A) in FSHR have been better analysed in women, whereas rs10835638 (−211 G>T) in FSHB seems to have a determinant role especially in men. However, studies considering the combined effect of th...

Perfluoroalkyl substances (PFASs) have been claimed as thyroid disrupting chemicals since the exposure to several PFASs was significantly associated with thyroid hormones derangements. Demographics such as sex, age, and disease status likely influence the associations between PFASs exposure and thyroid hormones since major hypothyroidism effects were observed among pregnant women and infants. This study aims to evaluate of the possible impact of legacy and new-generation PFAS ...
