The androgen receptor (AR) mediates the effects of male sexual hormones on development and physiology. Alterations in AR function are central to reproductive disorders, prostate cancer, and Kennedy disease. AR activity is influenced by post-translational modifications, but their role in AR-based

A major challenge in medical genetics is to characterize variants of unknown significance (VUS). Doing so would help delineate underlying causes of disease and the design of customized treatments. Infertility has presented an especially difficult challenge with respect to not only determining if a

OBJECTIVE To examine whether Arg554Lys polymorphism in the gene for aryl hydrocarbon receptor (AHR) and/or Pro185Ala polymorphism in the gene for aryl hydrocarbon receptor repressor (AHRR) constitutes a susceptibility locus for dioxin-related male infertility. METHODS Association study of male

Semen abnormality (SA) male infertility has become a worldwide reproductive health problem. The invasive tests (e.g., testicular biopsy) and labor-intensive methods of semen collection severely inhibit diagnosis of male infertility. In addition, the pathogenesis and biological interpretation of male

OBJECTIVE DAX-1 (NR0B1) is an orphan nuclear receptor, which plays a critical role in development and regulation of the adrenal gland and hypothalamo-pituitary-gonadal axis. Mutations in NR0B1 lead to adrenal hypoplasia congenita (AHC), hypogonadotropic hypogonadism (HH) and azoospermia in men.

OBJECTIVE The aim of this study was to analyze the seminal plasma of patients with idiopathic/male factor infertility and healthy controls with proven fertility by NMR spectroscopy, with a hope of establishing difference in biomarker profiles, if any, between the groups. METHODS A total of 103

This study reports the first clearly defined heteroplasmic mutation in immature human sperm cells. The human sperm mitochondrial genome from residue 8186-9341 was analysed with the aim of identifying point mutations which may be associated with human male infertility. The semen samples analysed were
