Objective:
To evaluate the changes of the semen quality in uremia patients before renal transplantation.
Methods:
The semen of 24 patients with uremia and 12 normal volunteers was analyzed.
Results:
The semen volume, sperm motility, survival rate, density and morphological normality percentage were (2.5 +/- 0.4) ml, (13.4 +/- 3.9)%, (25.4 +/- 5.6)%, (20.6 +/- 4.5) x 10(6)/ml and (16.8 +/- 2.1)%, respectively, significantly lower than those of the normal group (P < 0.01).
Conclusion:
Semen qualities were lowered significantly and spermatogenesis severely affected in patients with uremia.
