CONTEXT: Hyperinsulinemia can lead to pathologic ovarian growth and androgen production. CASE DESCRIPTION: A 29 year old woman developed an autoantibody to the insulin receptor (Type B insulin resistance), causing extreme insulin resistance and hyperinsulinemia. Testosterone levels were elevated to the adult male range. Treatment with gonadotropin releasing hormone (GnRH) analog led to normalization of testosterone, despite persistent extreme insulin resistance...

The levels of anti-Müllerian hormone, follicle-stimulating hormone, and testosterone were studied in rats after removal of the uterine horns, oviducts, or combined surgery. The effects of preventive salpingectomy on ovarian reserve were studied. After preventive salpingectomy, the level of anti-Müllerian hormone was low throughout the experiment, follicle-stimulating hormone increased only by the end of observation (on day 40), and testosterone level decreased only on day 10. Hysterectomy alone caused no changes in the concentrations of the studied hormones on day 10 after surgery...

Depression (DEP) is one of the main disabling diseases and is considered a contributor factor for erectile dysfunction (ED). Both of these conditions may be associated with hormonal changes and sleep disturbances. We aimed to evaluate the interaction between ED complaints and depression symptoms on sleep parameters, hormone levels and quality of life in men. This was a cross-sectional study of 468 men aged 20-80 years. The participants were classified according to the presence of ED and/or DEP in groups of healthy individuals, ED, DEP and DEP with ED (DEP-ED)...

Disruption of the balance oxidants, antioxidants cause various pathophysiological conditions such as lipid peroxidation, protein degradation, or DNA damage. We have examined possible effects of kisspeptin-10 on the structural damage produced by methionine-induced lipid peroxidation in testicle tissue of young rats. Kisspeptin-10 did not significantly affect spermatogenic cells in seminiferous tubules. Testosterone levels decreased in the methionine group as compared with the control group but without statistical significance...

BACKGROUND: Although muscle mass declines with testosterone deficiency in men, previous studies of muscle function have not demonstrated consistent deficits, likely due to relatively insensitive methodology. Our objective was to determine the effects of testosterone deprivation on the biomechanical function of individual lower-limb muscles. METHODS: We conducted a 12-month prospective, observational case-control study of 34 men newly commencing androgen deprivation treatment (ADT) for prostate cancer and 29 age-matched prostate cancer controls...

Ethanol consumption is associated with spermatogenesis damage and testosterone level alterations. Alcohol remains the most commonly used substance among athletes and sports enthusiasts. This study evaluated whether resistance physical exercise can reduce the testicular damage caused by ethanol exposure. A total of 36 ethanol drinking (UChB) rats were divided into four groups: C (control rats), ETOH (ethanol consumption), ETOH + T (ethanol consumption + physical training), and T (group physical training)...

In epidemiologic studies focused on adults, obstructive sleep apnea (OSA) has higher prevalence in men than in women. The evidence supporting a gender-related discrepant prevalence of OSA is however much more tenuous in children. Here, we aimed to review the evidence concerning gender- based differences in the prevalence of OSA in children, and if so, to examine the evidence with the intent to identify potential factors that may account for this putative association. Gender-based perception and reporting of clinical manifestations of OSA may be modulated by several social and cultural factors in children...

The increasing intensity of exercise enhanced corticosterone and lactate production in both humans and rodents. Our previous studies also demonstrated that lactate could stimulate testosterone production in vivo and in vitro. However, the production of testosterone in response to combined corticosterone and lactate on Leydig cells, and underlying molecular mechanisms are remained unclear. This study investigated the changes in testosterone levels of Leydig cells upon exposure to lactate, corticosterone or combination of both, and revealed the detailed mechanisms...

This article focuses on the effects of prenatal exposure to genistein on the mother, her pregnancy and reproductive functions of the male progeny, since these issues have ethological relevance in both animals and humans. Pregnant Wistar rats received i.p. injections of genistein at a dose level of 2, 20 or 100 mg/kg body weight daily from 12(th) to 19(th) day of gestation. Male pups from control and genistein exposed animals were weaned and allowed to develop until 100 days of age; however, when they were 90 days old, twelve males from each group were cohabited with untreated 90-day old females for 8 days...

Sex differences in brain structure and behaviour are well documented among vertebrates. An excellent model exploring the neural mechanisms of sex differences in behaviour is represented by sex-role-reversed species. In the majority of bird species, males compete over access to mates and resources more strongly than do females. It is thought that the responsible brain regions are therefore more developed in males than in females. Because these behaviours and brain regions are activated by androgens, males usually have increased testosterone levels during breeding...

Erectile dysfunction and low sexual desire are multifactorial diseases. The decrease in testosterone levels is one of the causes, but the effect of estradiol is not well known. Moreover, study has shown that the testosterone/estradiol ratio has more influence over sexuality than does estradiol alone. The aim of the study was to determine whether the balance between testosterone and estradiol has any relation to some aspects of sexual function. It was an ambispective study of 230 patients with urological problems unrelated to sexuality...

Feminine physical characteristics in women are positively correlated with markers of their mate quality. Previous research on men's judgments of women's facial attractiveness suggests that men show stronger preferences for feminine characteristics in women's faces when their own testosterone levels are relatively high. Such results could reflect stronger preferences for high quality mates when mating motivation is strong and/or following success in male-male competition. Given these findings, the current study investigated whether a similar effect of testosterone occurs for men's preferences for feminine characteristics in women's voices...

OBJECTIVES: Sugar cane molasses is a commonly used ingredient in several food products. Contrasting reports suggest that molasses may have potential adverse or beneficial effects on human health. However, little evidence exists that examines the effects of molasses on the different physiological systems. This study investigated the effects of sugar cane molasses on various physiological systems using in vivo and in vitro methods. MATERIALS AND METHODS: Molasses was administered orally to BALB/c, male mice and animals were randomly assigned into either a treatment or control group...

INTRODUCTION: Tramadol exhibits an effect profile similar to that of opioid agonists, and tramadol abuse seems to be a problem for a number of countries. The relationship between tramadol and sexual function appears to be controversial. Men with premature ejaculation (PE) may benefit from taking tramadol off label; however, these patients live "on a knife's edge" and are exquisitely sensitive to develop other sexual dysfunctions. AIM: To review the literature regarding the problem of tramadol abuse and its relationship with sexual function...

Women have a lifetime risk of major depression double that of men but only during their reproductive years. This sex difference has been attributed partially to activational effects of female sex steroids and also to the burdens of pregnancy, childbirth, and parenting. Men, in contrast, have a reproductive period difficult to delineate, and research on the mental health of men has rarely considered the effects of fatherhood. However, the couple goes through a number of potentially stressing events during the reproductive period, and both mothers and fathers are at risk of developing peripartum depression...
