Tramadol, one of the most commonly abused drugs in Middle East, impacts spermatogenesis and disturbs reproductive hormones in animal studies. We aimed to investigate tramadol impact on sperm quality and on levels of testosterone, prolactin and gonadotropins, in tramadol abusers (n = 30) to age-matched control (n = 30). Abusers had significantly low percentages of sperm motility, normal forms and vitality compared with control (95% CI -40.7 to -19.3, -13.5 to -9.3 and -31.9 to -9.7 respectively). Hypoandrogenism (95% CI -4...

INTRODUCTION: Bisphenol A (BPA) is suspected to cause hormonal imbalance in humans. Dietary factors are known to bring changes in hormonal profile. In order to study chemico-biological interaction of iron deficiency on toxicity outcome of BPA exposure, we studied the modulatory effects of iron deficiency on the hormone levels in rats chronically-exposed to BPA. METHODS: Weanling rats maintained on normal and iron-deficient diets were exposed to low level of BPA at 0, 1, 5 and 10 ppm for six months through drinking water...

Waterborne microcystin-LR (MC-LR) has been reported to disrupt sex hormones, while its estrogenic potency remains controversial. We hypothesized that MC-LR could induce estrogenic effects via disrupting sex hormone synthesis, and verified this hypothesis by in vitro and in vivo assays. Effects of MC-LR (1, 10, 100, 500, 1000 and 5000 μg/L) on steroidogenesis were assessed in the H295R cells after 48 h. The contents of 17β-estradiol (E2) and testosterone (T) increased in a non-dose-dependent manner, which showed positive correlations with the expression of steroidogenic genes...

In many social species, organisms adaptively fine-tune their competitive behavior in response to previous experiences of social status: Individuals who have prevailed in the past preferentially compete in the future, whereas those who have suffered defeat tend to defer and submit. A growing body of evidence suggests that testosterone functions as a "competition hormone" that coordinates this behavioral plasticity through its characteristic rise and fall following victory and defeat. Although well demonstrated in competitions underpinned by dominance (fear-based status derived from force and intimidation), this pattern has not been examined in status contests that depend solely on prestige-respect-based status derived from success, skills, and knowledge in locally valued domains, devoid of fear or antagonism...

We review the literature on aggression in women with an emphasis on laboratory experimentation and hormonal and brain mechanisms. Women tend to engage in more indirect forms of aggression (e.g., spreading rumors) than other types of aggression. In laboratory studies, women are less aggressive than men, but provocation attenuates this difference. In the real world, women are just as likely to aggress against their romantic partner as men are, but men cause more serious physical and psychological harm. A very small minority of women are also sexually violent...

Carcinogenesis is frequently linked to genetic background, however, exposure to environmental risk factors has gained attention as the etiologic agent for several types of cancer, including prostate. The intrauterine microenvironment has been described as a preponderant factor for offspring health; and maternal exposure to insult has been linked to chronic disease in older offspring. Using a model of maternal exposure to low protein diet (LPD; 6% protein), we demonstrated that impairment of offspring rat prostatic growth on postnatal day (PND) 21 was associated with prostate carcinogenesis in older offspring (PND 540)...

Aging affects metabolism, leading to physiological and functional impairments, and is also related to changes in body composition, including reduced skeletal muscle mass and increased body fat. These changes are correlated with the pathophysiology of sarcopenia, which is defined as age-related loss of skeletal muscle mass and strength. Low testosterone levels are associated with unfavorable body composition changes, and sex hormones decrease with aging. Androgen deficiency, along with lack of exercise and poor nutrition, may be among the modifiable contributors to sarcopenia...

The steroid hormone testosterone (T) has been suggested to influence reactive aggression upon its action on the basolateral amygdala (BLA), a key brain region for threat detection. However, it is unclear whether T modulates resting-state functional connectivity (rsFC) of the BLA, and whether this predicts subsequent aggressive behavior. Aggressive interactions themselves, which often induce changes in T concentrations, could further alter BLA rsFC, but this too remains untested. Here we investigated the effect of endogenous T on rsFC of the BLA at baseline as well as after an aggressive encounter, and whether this was related to behavioral aggression in healthy young women (n = 39)...

Men with type 2 diabetes (T2D) and obesity are often characterised by low testosterone (T). We aimed to determine whether exenatide (EXE) combined metformin (MET) treatment has a better effect on serum total testosterone (TT) levels than glimepiride (GLI) combined MET treatment in men with T2D and obesity. In a multicentre, 12-week observational study, 176 obese T2D men with failed glycaemic control were included in the study: ninety men (mean age, 43.00 ± 8.50 years) in EXE + MET group and 86 men (mean age, 44...

BACKGROUND: Testicular sperm extraction (TESE) is a surgical procedure to retrieve spermatozoa from the testes of men with azoospermia to help them achieve biological parenthood. Although effective, the surgical procedure is not without complications and haematoma, devascularization, inflammation and a decrease in testosterone levels have been described as such. The prevalence and duration of hypogonadism and associated symptoms after TESE have not been studied systematically. OBJECTIVE AND RATIONALE: In this systematic review we addressed the following research questions: Are serum testosterone levels decreased after TESE and, if so, do these levels recover over time? What is the prevalence of symptoms and signs related to hypogonadism after TESE and are they related to testosterone levels? SEARCH METHODS: We searched the databases Pubmed and Embase from 1 January 1993 to 26 June 2017...
