s: Testosterone deficiency (TD) profoundly affects men’s quality of life. Men receiving testosterone therapy often experience resolution or improvement in their sexual symptoms and non-sexual health benefits. Although testosterone has been available since 1930s, the diagnosis and management of TD can be challenging and many controversies still exist. Clinical assessment based on symptoms and si...
Testosterone deficiency leads to bone loss and testosterone treatment has a beneficial effect. This study investigated the effects of normalizing serum testosterone on bone mineral density in 45 men with osteoporosis, diagnosed with testosterone deficiency (serum testosterone levels <12.1 nmol/L, T-scores: (mean ± SD) -3.12 ± 0.45, minimum: -4.10, and maximum: -2.60). In a cumulative, prospecti...
Testosterone products are recommended by some prescribers in response to a diagnosis or presumption of "low testosterone" (low-T) for cardiovascular health, sexual function, muscle weakness or wasting, mood and behavior, and cognition. We performed a systematic review of 156 eligible randomized controlled trials in which testosterone was compared to placebo for one or more of these conditions. ...
The metabolic clearance rate (MCR) and blood production rate (BP) of testosterone (T) and dihydrotestosterone (DHT), the conversion of plasma testosterone to plasma dihydrotestosterone, and the renal clearance of androstenedione, testosterone, and dihydrotestosterone have been studied in man. In eight normal men, the MCR(T) (516+/-108 [SD] liters/m(2)/day) was significantly greater than the MCR...
The effects of testosterone (T) and 176-estradiol (E2) on the prostate of castrated rats were investigated by histopathological and immunocytochemicar procedures. A significant increase in prostatic weight occurred after 6 weeks treatment with T alone and in combination with E2. The greatest increase in prostatic weight occurred after the administration of T plus E2. Histopathologically, glandu...
In a reliable signalling system, individual quality is expected to mediate the costs associated with ornamental displays, with relatively lower costs being paid by individuals of higher quality. These relative costs should depend not only on individual quality, but also on levels of intra-sexual competition. We explored the current and delayed effects that testosterone implants have on bird orn...
Three different forms of testosterone (T) replacement therapy were compared; they were the intramuscular injection of mixed testosterone esters 250 mg; the subcutaneous implantation of 6 X 100 mg pellets of fused testosterone; and the oral administration of testosterone undecanoate (TU) 80 mg twice daily. Six hypogonadal males were treated with oral TU for an eight week period, during which tim...
Abstract Research has demonstrated that increases in testosterone (T) concentration can affect the expression of behaviours and preferences are typical high mating effort. However, little research considered whether such T strategy more generally this is achievable using a physical intervention. In pilot study, we examined exercise-induced changes covary with, or predict, male strategy. Healthy...
Testosterone deficiency is commonly observed in male patients with chronic obstructive pulmonary disease (COPD), which characterized by inflammation of the airways and emphysema. Although clinical trials have indicated that testosterone replacement therapy can improve respiratory function COPD, role pathogenesis COPD remains unclear. The aim this study was to explore effect on development emphy...
The effects of testosterone on functional recovery in stroke patients have not previously been studied. The purpose of the study was to determine the effects of pre-rehabilitation serum testosterone levels on functional recovery in male stroke patients. In total, 111 male stroke patients admitted to our department were enrolled in the study (age: 74 ± 10 years, days from stroke onset: 36 ± 14 d...
