INTRODUCTION AND OBJECTIVES The best indicators to the diagnosis of hypogonadism are free and bioavailable testosterone circulating levels. Free and bioavailable testosterone measurements are complex. However, simple kits for direct measurement of free testosterone by analog immunoassay are available. We examined the utility of an enzymoimmunoassay kit for free testosterone measurement. MATER...
The purpose of this study was to examine changes in selected physiological and performance variables of male tennis players (n=8) during a 3-day tennis tournament and the following 2-day recovery period. Each player played three two-hour tennis matches. The following measurements were taken: blood samples for serum testosterone T, cortisol C, creatinekinase CK, performance tests of maximal isom...
Context Studies of the possible cardiovascular risk of testosterone treatment are inconclusive. Objective To determine the effect of testosterone treatment on cardiovascular biomarkers in older men with low testosterone. Design Double-blind, placebo-controlled trial. Setting Twelve academic medical centers in the United States. Participants In all, 788 men ≥65 years old with an average ...
The aim of this study was effect of a single session of weight-lifting exercise on serum testosterone and cortisol and testosterone-cortisol ratio changes in elite weight-lifter of Mazandaran state. 10 elite weight-lifter of Mazandaran state was selected randomly. Moderate-intensity exercise was contained stand snatch (2 sets with 3 repeats of 60 one repeat maximum), Olympic snatch (2 sets with...
background: acyclovir (acv), a synthetic purine nucleoside analogue, is known to be toxic to gonads. objective: the current study evaluated cytotoxicity of acv on histopathological changes in testis tissue and serum testosterone and lipid peroxidation concentrations of male rats. materials and methods: animals were divided into five groups. one group served as control and one group served as co...
The male aging process brings about declines in hormonal function including a gradual decline in bioavailable testosterone levels. Animal studies suggest that testosterone modulates cognitive function through enhancing acetylcholine release and up-modulation of nicotinic receptors. Tau protein deposition is also affected by androgen supplementation in animals. We hypothesize that testosterone r...
BACKGROUND To evaluate the effect of internal spermatic vein (ISV) embolization on levels of serum testosterone and free testosterone and on spermatogenesis. METHODS The files of 83 infertile men treated for varicocele were reviewed for changes in serum testosterone, free testosterone and spermatogenesis after ISV embolization. RESULTS Mean serum testosterone concentration rose after emboli...
The relationship between varicocele and hypogonadism becomes clearer everyday thanks to the most recent literature, particularly with regards impact of repair on serum testosterone level improvement in hypogonadal patients. We selected English articles published from 1964 September 2021. search terms “varicocele” “hypogonadism” were used as filters. A total 102 studies have been obtained. For m...
Background and Aim: Hirsutism is defined as male pattern hair growth in females which affects 10% of women. Our aim was to compare free salivary and free serum testosterone levels in women with hirsutism and healthy controls.Methods: This study was a case-control study in which 30 hirsute women in child bearing age were recruited and compared with 10 healthy controls. For each patient, a questi...
Context: There is growing interest in the role of low testosterone levels on health in women. However, the effects of lower testosterone levels on decline in physical performance or muscle strength in older women have not yet been investigated. Objective: To investigate the associations between low testosterone levels and three year change in muscle strength and physical performance in a popula...
