Background: Leptin, a 16-KDa peptide hormone secreted from theadipose tissue, plays an important role in the regulation of energyintake and expenditure and body weight regulation; furthermore,it has a regulatory function on the reproductive system. The aimof this study was to assess the relationship between serum leptinlevels and sex hormones in psoriatic patients and control groupand to determ...

In men chronic heavy drinking interferes with reproductive hormones which are responsible for sexual maturation, sperm development and fertility. Alcohol is directly toxic to the testes; causing reduced testosterone levels.The present study was designed with an aim to elucidate the effect of oxidative stress on plasma testosterone level and hypothalamic pituitary gonadal (HPG) axis function in ...

BACKGROUND High circulating luteinizing hormone (LH) level is a typical biochemical feature of polycystic ovary syndrome (PCOS) whose pathophysiology is still unclear. Certain mutations of LH and LH receptor (LHR) may lead to changes in bioactivity of these hormones. The aim of this study was determine the role of the LH and LHR polymorphisms in the pathogenesis of PCOS using a genetic approach...

BACKGROUND Nickel exposure is recognized as an endocrine disruptor because of its adverse effects on reproduction. AIM This study was designed to investigate the possible testiculo-hormonal perturbations on workers occupationally exposed to nickel and to assess its effects on human male sexual function. METHODS Cross-sectional comparative study, comprising 105 electroplating male non-smoker...

The effects of prostaglandin E1 (PGE1) and indomethacin (IDM) on the release of several pituitary hormones from the rat pituitary were investigated in vitro. An addition of 2 microng/ml of PGE1 to the medium elicited the release of growth hormone (GH) and prolactin, but not of adrenocorticotropin (ACTH) and luteinizing hormone (LH). Although the addition of 1 microng/ml of IDM alone resulted in...
