AIM To investigate the relationships of serum testosterone, insulin-like growth factor (IGF)-1 and IGF-binding protein (IGFBP)-3 levels with prostate cancer risk and also with known prognostic parameters of prostate cancer in Korean men who received radical retropubic prostatectomy (RRP) for clinically-localized prostate cancer. METHODS Serum levels of total testosterone, free testosterone, I...
Background: Aging in men causes a gradual decline in endogenous testosterone levels, which may have detrimental effects on their health status. Testosterone deficiency is thought to promote atherosclerosis by modulating lipid metabolism. Therefore, this study was conducted to evaluate the serum testosterone level and its correlation with lipid profile in men aged ≥60 years old. Methods: All el...
A rapid and sensitive radiometric assay for assessing the potential of drugs to inhibit cytochrome P450 (P450) 3A4/5 in human liver microsomes is described. In contrast to the conventional testosterone 6beta-hydroxylation assay, the new method does not require high-performance liquid chromatography (HPLC) separation and mass spectrometry. The assay is based on the release of tritium as tritiate...
Introduction: Studies reveal that there is an association between smoking and serum levels of sexal steroid hormones. The main aim of this study was to determine the effects of cigarette or waterpipe smoking on serum level of LH, FSH, and testosterone in male rats. Methods: Male Wistar rats were randomly divided into control, cigarette, and waterpipe smoking groups, each consisting of 10 part...
effect of propylthiouracil (ptu)-induced hypothyroidism during the prepubertal period, at a dose of oneg per kg of the diet, on serum testosterone level and seminal characteristics of fars indigenous chickens wasstudied. ptu was fed between 7th to 13th weeks of age and semen was collected at weekly intervals, starting at 21st week of age and continued for seven weeks. the effect of ptu treatmen...
The purpose of this study was to survey effects of twelve weeks endurance training on serum levels of selected hormones in underweight men. Eighteen healthy underweight men were randomly divided at two groups: endurance training and control. Serum levels of adiponectin, testosterone, and cortisol were assessed before and after training. Endurance training protocol consisted of twelve weeks peda...
Background and Aim: Womenchr('39')s sexual function decreases during menopause, which in turn reduces their quality of life. Some studies have suggested that physical activity is associated with improved sexual function and increased blood androgens. The aim of this study was to investigate the effect of concurrent training on serum levels of testosterone, dihydroepiandrosterone and sexual func...
This study aims to investigate the effect of xylopia aethiopica on the sexual behavior of adult male rats. Fort eight adult male wistar rats were used for the study. They were randomly divided into four groups of 6 animals each: group 1 was control, while groups 2, 3 and 4 were test groups treated daily with 0.5, 2 and 10 mg/kg body weight respectively of hydro-methanolic fruit extract...
Background: The aim of this study was to investigate the short term protective effect of oxytocin on testicular ischemia reperfusion injury immediately after detorsion in a rat model. Materials and Methods: Twenty adult rats were randomly divided into four groups: Control, Ischemia- Reperfusion (IR), Oxytocin and IR+ Oxytocin. Testicular ischemia was achieved by torsion of the left testis 720° ...
