OBJECTIVETo evaluate the changes of the semen quality in uremia patients before renal transplantation.

METHODSThe semen of 24 patients with uremia and 12 normal volunteers was analyzed.

RESULTSThe 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).

CONCLUSIONSemen qualities were lowered significantly and spermatogenesis severely affected in patients with uremia.
