Introduction. Patients with late onset hypogonadism (LOH) also suffered from lower urinary tract symptoms (LUTS) and LOH symptoms. The objects of this study are to evaluate the efficacy of testosterone replace therapy (TRT) by testosterone ointment (Glowmin: GL) for LUTS in LOH patients.Methods. The Aging Male Symptom (AMS) scale, Medical Outcomes Study (MOS) 36-Item Short-Form Health Survey (SF-36), International Index of Erectile Function (IIEF-5) and the International Prostate Symptom Score (IPSS) were obtained from patients with LOH. A total of 41 patients with LOH have been treated with TRT using 6 mg/day of GL for 3 months. Serum free testosterone levels (FT) and these four scores were compared before and after TRT.Results. Serum FT levels and the scores for the four parameters of AMS, six of eight domains in SF-36, IIEF-5 and total IPSS improved significantly after 3 months TRT. In addition, all IPSS domains also improved significantly, and voiding disturbance seems to have improved more than storage disturbance (P?=?0.0280 vs. 0.0483).Conclusion. TRT by administration of GL is considered to be effective in the improvement of not only ED and LOH symptoms, but also LUTS (especially voiding disturbance) of patients with LOH. 相似文献

The role of estrogens in male physiology has received little attention until recently. However, it is now becoming more and more evident that estrogens are jar more important for a normal junction of reproduction and non-reproductive junctions in men than supposed. Furthermore, although estrogen has been discussed in the context of a decline in sperm number in men, there are no unequivocal data allowing any conclusion on a negative impact of environmental estrogens on male fertility so jar. 相似文献

The role of estrogens in male physiology has become more evident, as a consequence of the discovery of human models of estrogen deficiency such as estrogen resistance or aromatase deficiency. In males, testosterone is the major source of plasma estradiol, the main biologically active estrogen, only 20% of which is secreted by the testes. Plasma estrone, 5% of which is converted to plasma estradiol, originates from tissue aromatization of, mainly adrenal, androstenedione. The plasma concentration of estradiol in males is 2-3 ng/dl and its production rate in blood is 25-40 μg/24 h; both of these values are significantly higher than in postmenopausal women. Plasma levels of estradiol do not necessarily reflect tissue-level activity as peripherally formed estradiol is partially metabolized in situ; thus, not all enters the general circulation, with a fraction remaining only locally active. Of the factors influencing plasma estradiol levels, plasma testosterone is a major determinant. However, the age-associated decrease in testosterone levels is scarcely reflected in plasma estradiol levels, as a result of increasing aromatase activity with age and the age-associated increase in fat mass. Free and bioavailable estradiol levels do decrease modestly with age as does the ratio of free testosterone to free estradiol, the latter testifying to the age-associated increasewd aromatization of testosterone. Estradiol levels are highly significantly positively related to body fat mass and more specifically to subcutaneous abdominal fat, but not to visceral (omental) fat. Indeed, aromatase activity in omental fat is only one-tenth of the activity in gluteal fat. Estrogens in males play an important role in the regulation of the gonadotropin feedback, several brain functions, bone maturation, regulation of bone resorption and in lipid metabolism. Moreover, they affect skin metabolism and are an important factor determining sex interest in man. 相似文献
