BACKGROUND: Hip fracture occurs predominantly in older people, many of whom are frail and undernourished. After hip fracture surgery and rehabilitation, most patients experience a decline in mobility and function. Anabolic steroids, the synthetic derivatives of the male hormone testosterone, have been used in combination with exercise to improve muscle mass and strength in athletes. They may have similar effects in older people who are recovering from hip fracture. OBJECTIVES: To examine the effects (primarily in terms of functional outcome and adverse events) of anabolic steroids after surgical treatment of hip fracture in older people...

Non-alcoholic fatty liver disease (NAFLD) is more common in men than in women. Thus, it has been suggested that sex steroids do have a role in the development of NAFLD. The aim of the current paper is to illustrate the association between NAFLD and hypogonadism, by reviewing data derived from both human and animal studies. The prevalence of NAFLD is high in men with hypogonadism, including those with idiopathic hypogonadotropic hypogonadism (IHH), as well as in women in post- menopause, those under estrogen receptor antagonist treatment or women with Turner syndrome...

INTRODUCTION: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women. PCOS comprises a broad spectrum of anomalies, including hyperandrogenism, chronic anovulation, obesity, and infertility. Insulin resistance and its compensatory hyperinsulinemia play a key role in the pathogenicity of PCOS. This study compares the effects of 2 types of insulin sensitizer drugs, metformin and pioglitazone, on clinical, metabolic, and endocrine characteristics of women with PCOS...

Congenital adrenal hyperplasia comprises a group of disorders resulting from defects in enzymes required for the synthesis of cortisol. The clinical presentation depends on the specific enzyme defect. We report a rare case of congenital adrenal hyperplasia due to 17 alpha-hydroxylase deficiency. A 26-year-old female patient referred with hypertension and hypokalemia. She also had primary amenorrhea and lack of sexual development. The karyotype was 46, XY. Hormonal evaluation showed low serum levels of all steroid hormones, requiring alpha-hydroxylation, which included cortisol, 17 alpha-hydroxy progesterone, dehydroepiandrosterone sulfate, estradiol, and testosterone...

CONTEXT: The classic androgen synthesis pathway proceeds via DHEA, androstenedione and testosterone to 5α-dihydrotestosterone (DHT). However, DHT synthesis can also be achieved by an alternative pathway originating from 17α-hydroxyprogesterone (17OHP), which accumulates in congenital adrenal hyperplasia (CAH). Similarly, recent work has highlighted androstenedione-derived 11-oxygenated 19-carbon steroids as active androgens and, in CAH, androstenedione is generated directly from 17OHP...

In this study, the human H295R adrenocarcinoma cell line was exposed to different concentrations (0.04, 0.2, 1.0, 2.5 or 5 µg/mL) of nonylphenol (NP) to investigate its impact on the inhibition or induction of the steroid hormones production during 48 h of in vitro culture. The hormone production was measured using ELISA kits. Results of this in vitro study suggest various effect of nonylphenol in relatively low concentrations on the selected steroid hormones production by the human H295R adrenocarcinoma cell line...

Several large cohort studies have disclosed the trajectories of sex steroids changes overtime in men and their clinical significance. In men the slow, physiological decline of serum testosterone (T) with advancing age overlaps with the clinical condition of overt, pathological hypogonadism. In addition, the increasing number of comorbidities, together with the high prevalence of chronic diseases, all further contribute to the decrease of serum T concentrations in the aging male. For all these reasons both the diagnosis of late-onset hypogonadism (LOH) in men and the decision about starting or not T replacement treatment remain challenging...

Polycystic ovary syndrome (PCOS) is a heterogeneous, multi-causal, and genetically complex disorder, which is related to the failure in endocrine glands. Adiponectin has been reported to be low in PCOS, even in the absence of adiposity. Quercetin reduces serum glucose, insulin, triglycerides, and cholesterol levels and increases the expression and secretion of adiponectin. The aim of this study was to determine the effect of quercetin on the adiponectin-mediated insulin sensitivity in PCOS patients. Eighty-four women with PCOS were selected and randomly assigned to 2 groups of treatment and control...

Influenza severity increases with age, with hospitalization and mortality rates during seasonal influenza epidemics being higher in older men than age-matched women. Based on knowledge that with age, circulating testosterone levels decline in males, we hypothesized that reduced testosterone contributes to age-associated increases in influenza severity. A murine model was used to test this hypothesis. As in men, testosterone concentrations were lower in aged (18 months) than young (2 months) male C57BL/6 mice...

A CONTRIBUTION TO A SPECIAL ISSUE ON HORMONES AND HUMAN COMPETITION: Testosterone is theorized to increase retaliation after social provocation. However, empirical evidence in support of these theories is mixed. The present research investigated whether acute stress causally suppresses testosterone's association with retaliation. We also explored sex differences in behavioral responses to acute stress. Thirty-nine participants (51.28% male) were randomly assigned to a high- or low-stress condition. Then participants engaged in 20 one-shot rounds of the ultimatum game, which was used to assess retaliatory behavioral responses to unfair treatment...

In pediatric patients, basal testosterone and gonadotropin levels may be uninformative in the assessment of testicular function. Measurement of serum anti-Müllerian hormone (AMH) has become increasingly widespread since it provides information about the activity of the male gonad without the need for dynamic tests, and also reflects the action of FSH and androgens within the testis. AMH is secreted in high amounts by Sertoli cells from fetal life until the onset of puberty. Basal AMH expression is not dependent on gonadotropins or sex steroids; however, FSH further increases and testosterone inhibits AMH production...

Thyroid hormones (THs) - triiodothyronine (T3) and thyroxine (T4) - are essential for embryonic development in vertebrates. All vertebrate embryos are exposed to THs from maternal origin. As maternal TH levels are known to be essential to embryonic development, the natural variation of maternal THs probably represents a pathway of maternal effects that can modify offspring phenotype. However, potential fitness consequences of variation of maternal TH exposure within the normal physiological range and without confounding effects of the mother have never been experimentally investigated...
