Androgen and estrogen production rates were examined in 29 morbidly obese women with upper or lower body obesity. Although blood production rates of testosterone (T), dihydrotestosterone, and androstenedione (A4) were elevated in all of these women, those with upper body obesity (waist-height ratios, greater than 0.85) had higher T and production rates than(More)
Serum estrone (E1) and 17beta-estradiol (E2) were noted to be 2-fold elevated in a group of morbidly obese men. Urinary E1 and E2 production rates were elevated in proportion to the degree of obesity, with values as high as 127 and 157 micrograms/day, respectively. Although serum testosterone (T) concentrations were reduced in obese men, averaging 348 +/-(More)
The rat, an animal without testosterone-estrogen-binding-globulin, was treated with L-T4 to the point of hyperthyroidism in order to study the hypothalamic-pituitary-testicular axis during this condition. Hyperthyroidism led to a significant decline in serum FSH, a fall in serum LH which was not satistically significant, and no change in serum levels of(More)
Twelve persons with sexual ambiguity were identified in an isolated village in southern Turkey. Eleven were examined and had pseudovaginal perineoscrotal hypospadias; eight were studied. Serum and urine samples from five affected males and urine samples from three affected children were analyzed. Urine samples from another 26 villagers, mostly parents and(More)
We have previously shown that fructose and sorbitol given with a standard meal cause less increment in plasma glucose than sucrose and high fructose corn syrup (HFCS) in patients with NIDDM. However, there was no direct comparison of sucrose with HFCS. Sixteen men and one woman aged 54-67) with NIDDM were given either 35 g sucrose, 35 g fructose, or 43.75 g(More)
Obesity is a physiological state associated with alterations in hormone production and metabolism. These hormonal changes may bear on the increased risk for selected neoplastic disorders. Obesity is associated with increased estrone production in young and older women as well as in men. The source of this increased estrogen appears to be extragonadal(More)
Blood production rates of testosterone, dihydrotestosterone (DHT), and 3 alpha-androstanediol (3 alpha-diol) were found to be approximately 2-fold elevated in morbidly obese, nonhirsute, normally menstruating women. Values were intermediate between those found in normal women and those in a group of nonobese normally menstruating women with idiopathic(More)
We have tested the participation of endogenous opiate pathways in the negative feedback actions of gonadal steroids on pulsatile properties of luteinizing (LH) hormone release in normal men. To this end, sex steroid hormones were infused intravenously at dosages that under steady state conditions selectively suppressed either the frequency or the amplitude(More)
