In five adult male patients undergoing a 40-60% partial hepatectomy, serum sex hormone levels before and after hepatic resection were determined. Blood was drawn immediately prior to each surgical procedure and at specified time points postoperatively. Compared to hormone levels found prior to surgery, following major hepatic resection, estradiol levels increase at 24 and 48 hr, while testoster...
In vertebrates, including humans, the relative length of the second to the fourth digit correlates with sex hormone-dependent behavioural, psychological and physiological traits. However, despite a decade of research, the underlying mechanism linking digit ratio to these sex hormone-dependent traits remains unclear. Previous work suggests that during embryo development, circulating levels of pl...
Skeletal muscle can synthesize testosterone and 5α-dihydrotestosterone (DHT) from dehydroepiandrosterone (DHEA) via steroidogenic enzymes in vitro, but hormone levels and steroidogenic enzyme expression decline with aging. Resistance exercise has been shown to increase in plasma sex steroid hormone levels. However, it remains unclear whether resistance training can restore impaired steroidogeni...
The endocrinology of the aging male is complex, with multiple hormones along the hypothalamic-pituitary-testicular (HPT) axis interacting with one another in feedback. As men age, there is a small and progressive (not precipitous, as in women) decline in several sex hormones, in particular testosterone and dehydroepiandrosterone, and related increases in luteinizing hormone, follicle-stimulatin...
Introduction: Sex differences in outcomes of Spinal Cord Injury (SCI) suggest a sex-hormone-mediated effect on post-SCI pathological events, including glutamate excitotoxicity. This study aimed to investigate the importance of gonadal hormones on glutamate release subsequent to SCI in rats. Methods: After laminectomy at T8-T9, an electrolytic lesion was applied to the spinothalamic tracts of m...

INTRODUCTION Sex hormones have been implicated in the etiology of a number of diseases. To better understand disease etiology and the mechanisms of disease-risk factor associations, this analysis aimed to investigate the associations of anthropometric, sociodemographic and behavioural factors with a range of circulating sex hormones and sex hormone-binding globulin. METHODS Statistical analys...
CONTEXT Hypogonadism is a common clinical situation in male patients with liver cirrhosis. OBJECTIVES The aim of the present study was to evaluate the effects of orthotopic liver transplantation on testosterone, free testosterone and sex hormone-binding globulin in male with advanced liver disease and also to determine the relationship of these changes with Model for End-stage Liver Disease (...
Women with high circulating estrogen concentrations have an increased risk of breast cancer; thus, it is important to understand factors, including genetic variability, that influence estrogen concentrations. Several genetic polymorphisms that may influence sex hormone concentrations have been identified, including CYP17 (5'-untranslated region T-->C), CYP19 [intron 4 (TTTA)(n = 7-13) and a 3-b...
In order to accurately determine sex hormone dependency and hormone responsiveness in human esophageal carcinoma, the effects of sex hormones on the growth of esophageal carcinoma cell lines, KSE-1 and KSE-2 cells, were examined in vitro and in vivo. Cell proliferation of cultured KSE-1 cells was inhibited by treatment of estradiol and enhanced by dihydrotestosterone (DHT), whereas KSE-2 cells ...
