RESUMO
<p><b>OBJECTIVE</b>To explore the therapeutic effects of combination of varicocelectomy with hyperbaric oxygenation (HBO) in treating infertile patients with varicocele.</p><p><b>METHODS</b>Ninety-six patients were randomly divided into two groups: 40 patients in group A treated by varicocelectomy with HBO, and 56 in group B treated by solitary varicocelectomy.</p><p><b>RESULTS</b>The sperm density, sperm motility, sperm vigor, normality, serum testosterone, the pregnant rate of patients spouses were improved respectively in both two groups (P <0.01 or P < 0.05), and group A had better results than group B (P < 0.05). LH, FSH in group A decreased significantly after the therapy. Group A had higher sperm penetration asay (SPA) percentages than group B(P < 0.05), and the pregnant time of patient's spouses in group A was earlier than that in group B (P < 0.05).</p><p><b>CONCLUSION</b>Varicocelectomy with HBO can more effectively regulate reproductive hormone, improve semen quality, SPA index and pregnant rate than solitary varicocelectomy in treating infertile patients with varicocele and can markedly shorten the pregnant time.</p>
