REVIEW
Ahmad Majzoub, Edmund Sabanegh
Hypogonadism is a common clinical condition affecting men of different age groups. In addition to its sexual consequences, it has several implications posing significant concerns for a man's health and well-being. Recent advances in testosterone (T) supplementation have facilitated hypogonadism treatment. Despite that, patients complaining of infertility or seeking conception are still hindered by the unfavorable effects supplemental T has on testicular function. Consequently, alternative approaches that can stimulate endogenous T production are favored...

PROBLEM: Surfactant protein D (SP-D), a pattern recognition protein that regulates inflammation and immune homoeostasis, is expressed by testicular germ cells under the influence of testosterone. This study investigates the role of SP-D in testicular immune privilege and sperm functions. METHOD OF STUDY: Testicular levels of cytokines and immunoregulatory molecules were evaluated in lipopolysaccharide (LPS)-challenged SP-D gene knockout mice (SP-D(-/-) ). Further, sperm functions were assessed by computer-assisted sperm analyser (CASA) and in vitro capacitation...

BACKGROUND AND OBJECTIVE: Despite the American Academy of Pediatrics' recommendations against pediatric use of creatine and testosterone boosters, research suggests that many young teenagers take these dietary supplements. Our objective was to determine to what extent health food stores would recommend and/or sell creatine and testosterone boosters to a 15-year-old boy customer. METHODS: Research personnel posing as 15-year-old high school athletes seeking to increase muscle strength contacted 244 health food stores in the United States via telephone...

INTRODUCTION: 25-hydroxyvitamin D [25(OH)D] deficiency has been associated with low testosterone levels in men, but there are conflicting reports of its associations with sex hormones in women. Less is known about whether these associations are independent of adiposity and lifestyle factors, and whether they differ by race/ethnicity. AIM: To examine associations of 25(OH)D concentrations with sex hormone levels. METHODS: Cross-sectional analysis of 3017 men and 2929 women in a multi-ethnic cohort...

In vertebrates, male-typical sexual behavior (MSB) is largely controlled by gonadal androgens, however, the mechanism of this control is believed to vary among species. During immediate activation MSB is tightly correlated with circulating levels of androgens, while the organization of MSB by a hormonal event at a specific developmental period, early in ontogeny or during puberty, has been postulated in other lineages. Here, we put forward an alternative concept of "temporal organization". Under temporal organization longer exposure to circulating androgens is needed for the onset of MSB, which can continue for a long time after the levels of these hormones drop...

Lactose intolerance is characterized by low or inexistent levels of lactase, and the main treatment consists of dietary changes, especially replacing dairy milk by soy milk. Soy contains phytoestrogens, substances with known estrogenic activity, besides, glyphosate-based herbicides are extensively used in soy crops, being frequently a residue in soy beans, bringing to a concern regarding the consumption of soy-based products, especially for children in breastfeeding period with lactose intolerance. This study evaluated the pubertal toxicity of a soy milk rich feeding (supplemented or not with glyphosate, doses of 50 and 100 mg/kg) during prepubertal period in male rats...

Treatment to induce puberty in boys is indicated in those who do not undergo spontaneous development at a normal age. Stimulating development of the secondary sex characteristics is possible using gradually increasing doses of testosterone esters (TEs) via intramuscular (IM) administration, which is the most widely used method of testosterone (T) supplementation. When TEs are administered as monthly injection, serum T levels exhibit large fluctuations with supraphysiologic levels seen immediately after the injection followed by a decrease into the low range...

How anti-Müllerian hormone (AMH) and testosterone (T) interrelate in infertile women is currently largely unknown. We, therefore, in a retrospective cohort study investigated how infertile women with high-AMH (AMH ≥75th quantile; n=144) and with normal-AMH (25th-75th quantile; n=313), stratified for low-T (total testosterone ≤19.0ng/dL), normal-T (19.0-29.0ng/dL) and high-T (>29.0ng/dL) phenotypically behaved. Patient age, follicle stimulating hormone (FSH), dehyroepiandrosterone (DHEA), DHEA sulphate (DHEAS), cortisol (C), adrenocorticotrophic hormone (ACTH), IVF outcomes, as well as inflammatory and immune panels were then compared between groups, with AMH and T as variables...

BACKGROUND: Androgen deficiency (AD) is associated with increased risk of vascular disease. Dysfunctional remodeling of the vessel wall and atypical proliferative potential of vascular smooth muscle cells (VSMCs) are fundamental processes in the development of intimal hyperplasia (IH). We have demonstrated an inverse relationship between dihydrotestosterone (DHT) levels, matrix metalloproteinase activity, and VSMC migration and proliferation in vitro. Here, we investigated the role of AD and testosterone (TST) replacement in IH development in an animal model of vascular injury to elucidate mechanisms modulated by AD that could be playing a role in the development of vascular pathogenesis...

Clinical studies have revealed that testosterone supplementation had a positive effect on glucose homeostasis in type 2 diabetes mellitus (T2DM), but did not address how testosterone supplementation affected insulin responsiveness in the liver, a key glucose homeostatic organ. In this study, we aimed to study the effect of testosterone supplementation on hepatic insulin responsiveness and glucose homeostasis through liver in male high-fat diet-induced T2DM mice. Testosterone treatment to T2DM animals showed reduced hepatic glucose output...

INTRODUCTION: Female sexual response is a complex phenomenon in which psychological, neurologic, and vascular mechanisms and hormonal factors interact. During the arousal phase, they cooperate to increase genital blood flow, thus inducing engorgement of the clitoris and lubrication of the vagina. Regulation of vascular and non-vascular smooth muscle tone is the crucial event in the erectile process. Preclinical studies have suggested that nitric oxide (NO) is the main vasodilator neurotransmitter modulating, through the second messenger cyclic guanosine monophosphate (cGMP), clitoral flow vessels...

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...

The reduction of 17-oxosteroids to 17β-hydroxysteroids is one of the important transformations for the preparation of many steroidal drugs and intermediates. The strain Zygowilliopsis sp. WY7905 was found to catalyze the reduction of C-17 carbonyl group of androst-4-ene-3,17-dione (AD) to give testosterone (TS) as the sole product by the constitutive 17β-hydroxysteroid dehydrogenase (17β-HSD). The optimal conditions for the reduction were pH 8.0 and 30°C with supplementing 10g/l glucose and 1% Tween 80 (w/v)...

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...
