Although estrogen and testosterone deficiency have often been associated with the development of cardiac diseases in postmenopausal women, the benefits of estrogen or testosterone therapy are controversial. Supplementation high dose of estrogen or testosterone alone has been associated with many side-effects, especially estrogen. This study was aimed to investigate whether supplementation of testosterone in combination with low-dose estrogen conferred stronger cardioprotective effects on ovariectomized rats subjected to ischemia/reperfusion (I/R) injury...

Body wasting is a serious complication that affects a large proportion of patients with heart failure. Muscle wasting, also known as sarcopenia, is the loss of muscle mass and strength, whereas cachexia describes loss of weight. After reaching guideline-recommended doses of heart failure therapies, the most promising approach to treating body wasting seems to be combined therapy that includes exercise, nutritional counselling, and drug treatment. Nutritional considerations include avoiding excessive salt and fluid intake, and replenishment of deficiencies in trace elements...

Vertebral hemangiomas are the most common benign vertebral neoplasms and are generally asymptomatic. In the present study, we report the case of a 52-year-old male master ultra-marathoner suffering from a pathologic fracture of the thoracic spine due to a vertebral hemangioma. A further examination in the athlete revealed an accompanying osteopenia, which was most likely due to a deficiency in both vitamin D and testosterone. The treatment of the fracture consisted of percutaneous vertebroplasty. Shortly after the operation the athlete was able to continue running...

Gonadal hormones have been well-known to affect brain regions known to be involved in the modulation of mood and affective-related behavior. Prenatal stress might alter hypothalamic-pituitary-gonadal axis, it could be a target for development of affective-related disorders in male offspring. The present study was designed to examine an anxiety-like behavior in the adult male offspring with low levels of endogenous androgens delivered from pregnant dams exposed to prenatal stress from gestation day 15 to gestation day 19...

Accumulating evidences suggest that oxidative stress caused and deteriorated the aging related osteoporosis and pyrroloquinoline quinone (PQQ) is a powerful antioxidant. However, it is unclear whether PQQ can prevent testosterone deficiency-induced osteoporosis. In this study, the orchidectomized (ORX) mice were supplemented in diet with/without PQQ for 48 weeks, and compared with each other and with sham mice. Results showed that bone mineral density, trabecular bone volume, collagen deposition and osteoblast number were decreased significantly in ORX mice compared with shame mice, whereas PQQ supplementation largely prevented these alterations...

Context: Androgen deprivation therapy (ADT) is a common prostate cancer (PCa) treatment but results in muscular atrophy. Periodic increases in muscle protein synthesis (MPS) that occur after resistance exercise or protein intake may ameliorate this muscle loss, but the impact of these anabolic stimuli during ADT is unclear. Objective: To determine the acute MPS response to whey protein supplementation with and without resistance exercise during ADT. Design: Acute response in PCa patients vs age-matched controls (CON)...

Like elderly men, old male rhesus macaques show attenuated circulating levels of testosterone and dehydroepiandrosterone sulfate, and many of them also show reduced levels of daytime activity. It is unclear, however, if this age-associated behavioral change is causally related to the underlying decrease in circulating androgen levels. To test this possibility, old male rhesus macaques were given daily supplements of testosterone and DHEA for 6 months, designed to mimic the mean 24-hour circulating hormone patterns of young adults...

It is suggested that vitamin D status is associated with androgenic profile in women with polycystic ovarian syndrome (PCOS). Although several clinical trials are known in this regard, the results were inconsistent. Therefore, this study was aimed to conduct a systematic review and meta-analysis of published clinical trials to elucidate the possible effect of vitamin D supplementation on the androgen levels in adult females with PCOS. PubMed, SCOPUS, and Google Scholar were searched to identify related articles published up to January 2017...

The detection of boldenone, nandrolone, 5(10)-estrene-3β,17α-diol and 4-estrene-3,17-dione in a urine sample collected from a gelding having been treated with testosterone (500 mg "Testosterone Suspension 100", single dose, injected intramuscularly) in 2009 led the authors' laboratory to suspect that these 'testicular' steroids could be minor metabolites of testosterone in geldings. Administration trials on six castrated horses with "Testosterone Suspension 100" confirmed that low levels of boldenone, nandrolone, 5(10)-estrene-3β,17α-diol and 4-estrene-3,17-dione could indeed be detected and confirmed in the early post-administration urine samples from all six geldings...

Adequate plasmatic Vitamin D levels are crucial to maintain calcium homeostasis and bone metabolism both in the general population and in athletes. Correct dietary supply and a regular sun exposure are fundamental for allowing the desired and effective fitness level. Past studies highlighted a scenario of Vitamin D insufficiency among professional soccer players in several countries, especially in North Europe, whilst a real deficiency in athletes is rare. The typical seasonal fluctuations of Vitamin D are wrongly described transversally in athletes belonging to teams that play at different latitudes and a chronobiologic approach studying the Vitamin D circannual rhythm in soccer players has not been described yet...

Variation in an animal's spatial environment can induce variation in the hippocampus, an area of the brain involved in spatial cognitive processing. Specifically, increased spatial area use is correlated with increased hippocampal attributes, such as volume and neurogenesis. In the side-blotched lizard (Uta stansburiana), males demonstrate alternative reproductive tactics and are either territorial-defending large, clearly defined spatial boundaries-or non-territorial-traversing home ranges that are smaller than the territorial males' territories...

di-N-butylphthalate (DBP) is a ubiquitous environmental pollutant used for plastic coating and in the cosmetics industry. It has toxic effects on body health, especially the male reproductive system. Here, we investigated the effects of DBP on the male reproductive system of pubertal mice and explored the protective role of sulforaphane (SFN). The results showed that DBP significantly reduced the anogenital distance, testicular weight, sperm count and motility, and plasma and testicular testosterone levels and significantly increased the oxidative stress, sperm abnormalities, and testicular cell apoptosis...

Cardiovascular disease in women differs in clinical presentation, pathophysiology and prognosis from that in men. The role of estrogens and androgens may help explain such sex dimorphisms, being involved in cardiac function, endothelial function and vascular tone. In particular, the cardioprotective effect of estrogen replacement therapy is observed in postmenopausal women in a time-dependent manner, i.e. when it is initiated at their first menopausal symptoms. Postmenopausal women, beyond aged men, may also benefit from testosterone supplementation therapy...

Exposure of rabbit bucks to summer heat stress reduces their homeostasis and semen quality leading to a temporal subfertility. The potentiality of ethanolic extract of Moringa oleifera leaves (M. oleifera ethanolic extract (MLEE)) to reduce negative impacts of heat stress on physiological and semen quality traits was investigated. A total of 28 adult V-line rabbit bucks were randomly distributed among four experimental groups of seven rabbits each. The first group received water (placebo) and served as a control (M0)...
