CHANGES IN THE PITUITARY-TESTICULAR SYSTEM WITH AGE 总被引:7,自引:1,他引:7
H. W. G. BAKER H. G. BURGER D. M. de KRETSER B. HUDSON S. O'CONNOR C. WANG A. MIROVICS J. COURT M. DUNLOP G. C. RENNIE 《Clinical endocrinology》1976,5(4):349-372
In order to provide a comprehensive account of pituitary-testicular function in man, 466 subjects, ranging in age from 2 to 101 years, were studied to examine blood levels of the pituitary gonadotrophins (LH and FSH), the sex steroids testosterone and oestradiol, the binding capacity of the sex hormone binding globulin (SHBG), the free testosterone and oestradiol fractions, and the transfer constant for the peripheral conversion of testosterone to oestradiol. The results were compared with clinical indices of testicular size, sexual function and secondary sex hair distribution. Serum LH and FSH were low before puberty, increased in pubertal adolescents to levels somewhat above those of adults and subsequently increased progressively over the age of 40 years. Testosterone levels fell slowly after the age of 40, while there was a slight rise in plasma oestradiol with increasing age. FSH and testosterone showed small seasonal variations in young adult men, the lowest values being seen in winter. SHBG binding capacity was high in two prepubertal boys, fell in adult men, but increased in old age. Free testosterone and oestradiol levels fell in old age. The metabolic clearance rates (MCR) of testosterone and oestradiol also fell in old age, while the conversion of testosterone to oestradiol was increased. Many correlations were observed between various hormonal and clinical measurements. The evidence is consistent with a primary decrease in testicular function over the age of 40 years. 相似文献

Blood pressure has been measured in 209 children on first consultation when referred to the Obesity Research Clinic. Blood pressure correlated with estimates of obesity made by subscapular-skinfold thickness, and calculations of per cent body weight as fat. Neither age nor duration of the obesity showed significant correlation with the blood pressure. 相似文献
