Using constant infusions of [3H]testosterone and [14C]oestradiol or [3H]androstenedione and [14C]oestrone the dynamics of androgen and oestrogen metabolism and production in patients with hyperthyroidism were measured. The metabolic clearance rates of testosterone and oestradiol were decreased but those of androstenedione and oestrone were within the normal range. The conversion ratios of testosterone to androstenedione and of testosterone to dihydrotestosterone (DHT) were decreased whereas those of androstenedione to testosterone and androstenedione to DHT were increased. These changes could be explained by increased serum levels of sex hormone binding globulin which binds testosterone and DHT but not androstenedione. The fraction of androstenedione infused into and measured as oestrone in the blood was normal in seven out of nine subjects and the fraction of testosterone infused and measured as oestradiol was normal in all nine subjects. The production rates of testosterone and oestradiol were in the normal range but the production rates of androstenedione and oestrone were raised in half the subjects.

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 (MELD) score. Methods In a prospective study, serum levels of testosterone, free testosterone and sex hormone-binding globulin of 30 male adult patients with end-stage liver disease were measured 2 to 4 hours before and 6 months after orthotopic liver transplantation. Results Total testosterone levels increased after orthotopic liver transplantation and the number of patients with normal testosterone levels increased from 18 to 24. Free testosterone mean level in the pre-transplant group was 7.8 pg/mL and increased to 11.5 pg/mL (P = 0.10) and sex hormone-binding globulin level decreased after orthotopic liver transplantation returning to normal levels in MELD ≤18 - group (A) (P<0.05). Conclusions Serum level changes of testosterone, free testosterone and sex hormone-binding globulin are more pronounced in cirrhotic males with MELD ≤18. Serum levels of testosterone and free testosterone increase and serum levels of sex hormone-binding globulin decrease after orthotopic liver transplantation.
