ABSTRACT
<p><b>OBJECTIVE</b>To explore the relationship between the expression of caspase-3 in testicular germ cells of rats with experimental left varicocele (ELV) and apoptosis of germ cells.</p><p><b>METHODS</b>Twenty-four male SD rats were randomly divided into three groups with eight animals each sham-operation group (SOG), 30-day post-operation group (PG1) and 60-day psot-operation group (PG2). ELV model was established by the partial ligation of the left renal vein. To detect apoptosis of germ cells and expression of caspase-3, TUNEL assay and immunohistochemistry (SABC) were used respectively.</p><p><b>RESULTS</b>The number of caspase-3 positive germ cells per tubular cross section in left and right testes of rats in SOG, PG1, PG2 were 0.1175 +/- 0.0129, 0.2463 +/- 0.0421, 0.2938 +/- 0.0511 and 0.1650 +/- 0.0192, 0.2538 +/- 0.0219, 0.2775 +/- 0.0343, respectively. Compared with SOG, the expression of caspase-3 in bilateral testes of rats in PG1 and PG2 were increased, and the differences were statistically significant(P = 0.0115 and P = 0.0144).</p><p><b>CONCLUSION</b>Expression of caspase-3 protein increased in germ cells of rats with ELV, which may be one of the molecular mechanisms related to excessive testicular germ cell apoptosis.</p>
