BACKGROUND Literature proves anti-mullerian hormone (AMH) and total testosterone (TT) as two important reproductive hormones in male development, however evidence regarding age variations of these hormones is lacking. AIMS To estimate the normal serum AMH values and to assess the age-specific TT levels in men aged 30-70, we conducted the present population-based study. METHODS A total of 83...

OBJECTIVE we measured muscle strength and functional mobility in healthy men and women over the adult age range to investigate the changes with age and sex, and to establish the effects of the anthropometric indices height and weight. DESIGN cross-sectional study. SUBJECTS AND METHODS we recruited 74 healthy women (mean age 49.0, range 20-90) and 81 healthy men (mean age 51.6, range 20-90)....

BACKGROUND A reduction in compliance of the large-sized cardiothoracic (central) arteries is an independent risk factor for the development of cardiovascular disease with advancing age. METHODS AND RESULTS We determined the role of habitual exercise on the age-related decrease in central arterial compliance by using both cross-sectional and interventional approaches. First, we studied 151 hea...

OBJECTIVE Declines in working memory are a ubiquitous finding within the cognitive-aging literature. A unitary inhibitory selection mechanism that serves to guide attention toward task-relevant information and resolve interference from task-irrelevant information has been proposed to underlie such deficits. However, inhibition can occur at multiple time points in the memory-processing stream. H...

background: reactive oxygen species (ros) are a group of free radicals that in excessive amounts have negative influence on sperm quality and function. objective: we compared ros levels in seminal plasma of infertile men with this level in healthy donors. we also determined the ros level in semen of infertile men according to the etiology of infertility, and also the effect of smoking on its le...

Research on healthy aging in men has increasingly focused on age-related hormonal changes. Testosterone (T) decline is primarily investigated, while age-related changes in other sex steroids (dehydroepiandrosterone [DHEA], estradiol [E2], progesterone [P]) are mostly neglected. An integrated hormone parameter reflecting aging processes in men has yet to be identified. 271 self-reporting healthy...

PURPOSE: Cardiorespiratory fitness is suggested to be an important marker of cardiovascular risk, but is rarely evaluated in healthcare settings. In the present study directly measured peak oxygen uptake data (VO2peak) from a diverse population of 4637 healthy participants were used to develop and cross-validate a new non-exercise regression model of cardiorespiratory fitness for men and women....

Measurements of free noradrenaline and adrenaline were made in the urine of 28 men sampled after rest and exercise prior to, and following six and twelve weeks of an excercise programme. The training consisted of thirty minutes of running and walking four times per week at an intensity estimated at 75% of the age-predicted maximum heart rate. A fifteen minute standardized cycle ergometer work t...
