OBJECTIVES: To evaluate the effects of different dosages of cyclosporine A (CsA) on the main semen parameters and sperm morphology of the patients after renal transplantation. METHODS: The semen of 18 patients after renal transplantation treated with different dosages of CsA was analyzed and the semen parameters and sperm morphology were compared with those of 12 normal volunteers. RESULTS: There was not significant difference between the main parameters of the patients treated with 1.5-3.0 mg.Kg-1.d-1 of CsA and 3.1-5.5 mg.Kg-1.d-1 of CsA and those of the volunteers (P > 0.05), but the rate of normal sperm morphology was significantly different between the two groups(P < 0.05). CONCLUSIONS: Different therapeutic dosages of CsA did not have any effect on most of the semen parameters of the patients after renal transplantation, but did affect the sperm morphology.
