BACKGROUND: Clinically, the severity of uremia is known to be inversely proportional to sexual desire and activity in patients with chronic renal failure. We studied sexual function and sex hormones in male patients with symptomatic hyperparathyroidism before and 3 months after parathyroidectomy. STUDY DESIGN: From October 1998 to December 2000, 20 male patients with symptomatic secondary hyperparathyroidism were enrolled in this study. They underwent total parathyridectomy and auto-transplantation of 90 mg of tissue to the subcutaneous tissue of the forearm or thigh. They all had regular sexual partners and were sexually active. Preoperatively, hemoglobin, hematocrit, calcium, phosphorus, alkaline phosphatase, intact parathyroid hormone (iPTH), prolactin, testosterone, leutenizing hormone (LH), and follicle stimulation hormone (FSH) were checked routinely. Three months after operation those data were checked again. Sexual function was evaluated with the International Index of Erectile Function (IIEF). Monthly frequency of attempted sexual intercourse, satisfaction of attempted intercourse, and enjoyment of intercourse were individually analyzed preoperatively and 3 months postoperatively. RESULTS: Hemoglobin, hematocrit, testosterone, and LH were noted to have not significantly changed 3 months after surgery. Serum levels of calcium, phosphorus, alkaline phosphatase, FSH, and iPTH were significantly reduced, as were the levels of prolactin. But preoperative and postoperative FSH levels were within normal limits, and 70% of the postoperative alkaline phosphatase levels were above normal. Sexual function increased significantly 3 months after parathyroidectomy, as did monthly frequency of attempted intercourse, satisfaction of attempted intercourse, and enjoyment of intercourse. CONCLUSIONS: Sexual function of male patients with symptomatic hyperparathyroidism can possibly be improved by parathyroidectomy and autotransplantation. Decreases in the levels of prolactin, calcium, phosphorus, and iPTH are also noticed after parathyroidectomy.
