Kallmann syndrome (KS) is a clinically and genetically heterogeneous condition characterised by hypogonadotropic hypogonadism with anosmia or hyposmia. More than nineteen genes causing KS have been reported to date. KAL1, first identified to causing the X-linked form of KS, accounts for 10%-20% of KS patients. In this study, we designed a panel including 17 known genes causing KS for genetic diagnosis and research and report a typical and rare family of which three generations had been affected by KS. A novel CNV in Xp22...

Testosterone propionate-induced benign prostatic hyperplasia in rats is a common model that is widely used in studies of the effects and molecular mechanisms of drugs designed to treat benign prostatic hyperplasia. RT-qPCR is a widely used technique in gene expression studies. Proper normalisation is critical for accurate expression analysis. Currently, no validated reference genes are available for RT-qPCR in rat benign prostatic hyperplasia. Given that microRNAs regulate mRNA expression at the post-transcriptional level, they are usually studied together...

Testicular torsion-related oxidative stress causes a sequential chain of DNA damage, lipid peroxidation and cell death that leads to the derangement in the sperm functions and infertility. Capsaicin that has been applied for pain relief and cancer prevention possesses antioxidant properties which can be exploited to confer cell survival under ischaemic testis damage. Wistar male rats weighing 150-200 g were randomly divided into four groups: (i) sham group (all procedures except torsion of testis), (ii) ischaemia group (TT group), (iii) three TT groups treated with different dose of capsaicin (TT + different doses of Cap) and (iv) three control groups treated with different doses of capsaicin (100, 500 and 1000 ug/ml)...

Conventional cytogenetics has always been a favourite to detect chromosomal aberrations. Carriers of chromosomal translocation are often phenotypically normal but are infertile. Couples are often advised to go for karyotyping, but culture failure or improper metaphase spread with poor banding often makes the analysis difficult. We report here a novel translocation between short arm of chromosome 4 and long arm of chromosome 6 in an infertile man using an advanced molecular cytogenetic technique of Interphase Chromosome Profiling (ICP)...

Metabolic syndrome represents a collection of cardiovascular risk factors, including overweight, hypertension, dyslipidemia and impaired glucose metabolism, with insulin resistance. In recent years, the potential relationship between metabolic syndrome and male factor infertility has been studied. As endothelial dysfunction is the hallmark of metabolic syndrome, the aim of this work was to assess serum levels of YKL-40 as a marker of endothelial dysfunction in male patients with idiopathic infertility. The study revealed that YKL-40 levels were elevated in patients than controls denoting that endothelial dysfunction might play a role in the pathogenesis of idiopathic infertility and that YKL-40 as a marker of endothelial dysfunction could be a useful marker of idiopathic infertility...
