The effect of varicocele on Leydig cell function and testosterone production has been always a question. In this stud...
PURPOSE Late-onset hypogonadism (LOH) in aging males is a clinical and biochemical syndrome characterized by a decline in serum testosterone levels. LOH results in various physical and mental disabilities. We evaluated the relationship between serum testosterone levels and symptoms of LOH. MATERIALS AND METHODS During an andropause screening program, we examined responses to the Saint Louis u...
OBJECTIVE: To evaluate the relationship between serum level of testosterone and sex hormone-binding globulin in men with type 2 diabetes. MATERIALS AND METHODS: In this case-control study, forty men aged 40-70 with type 2 diabetes mellitus were randomly selected and compared with 40 non-diabetic men. The two groups were matched for their age and BMI. After complete observation and examination...

Background : In males, testosterone reduction is one of the complications of renal ischemia. Olive leaf is a significant source of bioactive phenolic compounds. They have better antioxidant capacity, anti-inflammatory and radical scavenging. The purpose of this study was to investigate the effect of olive leaf extract (OLE) on serum level of Gonadotropins and testosterone. Materials and Meth...
There has been an increase in the number of individuals seeking testosterone (T) replacement treatment (TRT) due to a decrease in their blood T levels. Prostate cancer (PCa) is also an important issue in the same age group. However, we, urologists, are anxious about PCa development after T treatment. This is because it has been assumed that T may cause PCa or exacerbate insidious PCa which is a...
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...
Recently, it has been concluded that measurement of the serum free testosterone level is crucial for evaluating male gonadal function. However, the extent of the decline of serum free testosterone levels with aging and the actual levels in male infertility have not yet been clearly defined. In this study, the clinical significance of serum free testosterone levels was evaluated in a total of 24...
