title: [Kidney transplantation improves spermatogenic function in patients with uremia].
abstract: OBJECTIVE
  To study the changes of testicular spermatogenic function after kidney transplantation.
  
  
  METHODS
  Thirty male patients with uremia underwent kidney transplantation. Semen analyses were made and sperm ultrastructural changes were studied before and after the operation.
  
  
  RESULTS
  Sperm viability, motility and movement velocity were significantly higher in the postoperative group than in the preoperative group [(70.08 +/- 2.86 vs (36.04 +/- 8.01)], [(76.15 +/- 3.75)% vs (39.27 +/- 4.14)%], [(16.80 +/- 1.11) microm/s vs (8.43 +/- 2.01)] micro/s, respectively (P < 0.01). Sertoli cell, acrosome and mitochondria structures inclined to normal after kidney transplantation.
  
  
  CONCLUSIONS
  Kidney transplantation can significantly improve spermatogenic function in patients with uremia.
