Abstract

To observe the influence of kidney transplantation (KT) on erectile and endocrine function, we evaluated the PBI, penile pulse volume plethysmography, RigiScan and endocrine study before and after KT in 21 patients. We also interviewed with these patients or their sexual partners before KT. at 3 months and 6 months after KT. 7 cases (33%) were improved, 8 cases (38%) were same and 4 cases(19%) were aggravated in sexual desire and erectile function and 2 cases (10% ) had been suffered from erectile dysfunction since 19 months and 6 years prior to KT. The PBI was changed from 0.97 +/- 0.09 to 0.95 +/- 0.16 and it was not a significant difference. The penile plethysmography was not a good screening test in the evaluation of erectile function in KF. But the Rigiscan could detect all of the tested aggravated cases and it was thought to be a good screening test. In the endocrine studies, testosterone and FSH were decreased and LH and prolactin were increased before KT but testosterone and LH were significantly decreased after KT. It was thought to be the influence of KT and immunosuppressive agent (cyclosporin A). In conclusion, sexual desire and erectile function may be improved by the KT and most reliable screening test was Rigiscan. Endocrine function may be affected by the KT and cyclosporin A.
