Examination of the semen quality of patients with uraemia and renal transplant recipients in comparison with a control group

Summary To examine the semen quality of patients with uraemia and renal transplant recipients, 40 patients with uraemia and 40 renal transplant recipients were included. According to their interval of post-transplantation, renal transplant recipients were subdivided into group A (22) ≤2 years and group B (18) >2 years. A total of 40 healthy men with normal fertility were included as the controls. Semen samples from all subjects were collected and analysed. The fertility index (FI) value was calculated. The FI value of the normal fertility men was 13.02 (14.26), that of the renal transplant recipient groups A and B were 5.53 (8.30) and 9.27 (22.49) respectively, while the FI of the patients with uraemia was 0.23 (0.76). Compared with the uraemia group, the FI values of renal transplant recipient group either group A or group B were significantly better (P   0.05). In conclusion, the FI of renal transplant recipients was recovered close to the level of healthy men with normal fertility 2 years after transplantation.
