Testosterone levels after bromocriptine treatment in patients undergoing long-term hemodialysis

Seventeen out of 34 male patients undergoing long-term hemodialysis had increased basal plasma prolactin levels (mean = 1344 +/- 1158.76 mU/L). Seven of these 17 patients having the greatest degree of erectile impotence were treated with 3.5 to 7.5 mg/day of bromocriptine. After a 4-week treatment period, basal plasma prolactin levels in all seven patients were within normal limits (mean = 210.2 +/- 66.97 mU/L). The treated patients reported an improvement in both libido and potency. At the same time, an increase in plasma testosterone levels was observed, while plasma LH and FSH levels were essentially unchanged.
