PURPOSE: Previous studies have shown that the removal of one testis leads to a compensatory mechanism in the contralateral one, but this was species and age dependent. The aim of this study was to check whether this compensation would still occur after the combination of a unilateral orchiectomy and gonadotoxic treatment, since this resembles the clinical situation of patients who have to undergo highly toxic cancer treatment and therefore choose to cryopreserve a testicular biopsy for fertility restoration purposes...

Dehydroepiandrosterone (DHEA), the most abundant sex steroid, is primarily secreted by the adrenal gland and a precursor hormone used by athletes for performance enhancement. Whole-body vibration (WBV) is a well-known light-resistance exercise by automatic adaptations to rapid and repeated oscillations from a vibrating platform, which is also a simple and convenient exercise for older adults. However, the potential effects of DHEA supplementation combined with WBV training on to body composition, exercise performance, and hormone regulation are currently unclear...

PURPOSE: Degarelix, a new GnRH receptor antagonist with demonstrated efficacy as first-line treatment in the management of high-risk prostate cancer, possesses some theoretical advantages over LHRH analogues in terms of avoiding "testosterone flare" and lower FSH levels. We set out to determine if pre-operative degarelix influenced surrogates of disease control in a randomized phase II study. EXPERIMENTAL DESIGN: 39 patients were randomly assigned to one of 3 different neo-adjuvant arms: degarelix only, degarelix/bicalutmaide, or LHRH agonist/bicalutamide...

Low free testosterone levels in men are associated with age-related cognitive decline and increased risk for neurotoxicity, resulting in disease. The mechanisms underlying these observations remain poorly defined. While rapid, androgen receptor-dependent activation of extracellular signal-regulated kinase (ERK) has been postulated as a neurotrophic and neuroprotective mechanism, actions of testosterone metabolites such as 5α-androstane-3α,17β-diol (3α-diol) may also be involved. We investigated the influence of 3α-diol on the induction of ERK phosphorylation in SH-SY5Y human female neuroblastoma cells and primary cortical neurons from male and female mice...

Inbred DDD/Sgn mice are heavier than inbred C57BL/6J mice. In the present study, we performed quantitative trait loci (QTL) mapping for body weight using R/qtl in reciprocal F2 male populations between the two strains. We identified four significant QTL on Chrs 1, 2, 5, and 17 (proximal region). The DDD/Sgn allele was associated with increased body weight at QTL on Chrs 1 and 5, and the DDD/Sgn allele was associated with decreased body weight at QTL on Chrs 2 and 17. A multiple regression analysis indicated that the detected QTL explain 30...

Alternative medicine is a widely accepted therapeutic approach for the management of various diseases. The Korean medicine, musulju (MSJ), has been traditionally used to improve vital energy in men with reduced physical strength and a weakened urinary system. The present study determined the mechanisms underlying the protective effect of MSJ against benign prostatic hyperplasia (BPH), a common disorder in elderly men that involves inflammation‑mediated imbalance between cell proliferation and death. MSJ treatment was demonstrated to decrease prostate weight, cell proliferation, and the protein expression of proliferating cell nuclear antigen in a rat model of BPH...

Male infertility is a complex, multifactorial and polygenic disease that contributes to ~50% cases of infertility. Previous studies have demonstrated that excess weight and obesity factors serve an important role in the development of male infertility. An increasing number of studies have reported that resveratrol may regulate the response of cells to specific stimuli that induce cell injury, as well as decrease germ cell apoptosis in mice or rats. In the present study, the semen quality and serum sex hormone levels were evaluated in 324 men, which included 73 underweight, 82 normal weight, 95 overweight and 74 obese men...

Diabetes mellitus significantly affects the male reproduction and sexual function. In the present study, we investigated the diabetes-induced dysfunction of seminal vesicles (SVs) in the diabetes-rat model and the role of antioxidants. Streptozotocin-induced diabetes after 4 weeks caused smaller size of the organs, hypercontractility, histological abnormalities, increased concentrations of malondialdehyde in the serum and tissue, overexpression of oxidative stress markers, and cleaved caspase-3 as identified by immunohistochemistry in the SVs...

Subnormal levels of testosterone are frequently found in men of higher age category. Hypogonadal men have lower life expectancy than men with full androgenization and cardiovascular disease, obesity or diabetes is often associated with hypotestosteronemia. Low testosterone level is risk factor for these diseases. However, until now it is not clear whether testosterone deficiency is a cause or consequence of atherosclerosis or metabolic syndrome. A handful of symptoms and metabolic risk markers in hypogonadal men can be ameliorated by testosterone supplementation...
