However, the type of DNA fragmentation - whether oxidative or of another nature - remains unknown. Thus, the aim of this study was to evaluate single- and double-stranded sperm DNA fragmentation, and oxidative-induced sperm DNA damage in m

8. Pacientes com azoospermia e varicocele devem ser submetidos à cirurgia para recuperar a fertilidade?
Resumo Introdução: A varicocele é sabidamente uma das causas de infertilidade nos homens. A presença de veias espermáticas dilatadas pode criar um ambiente hostil para a espermatogênese. Isso é causa de baixa qualidade e quantidade da produção do esperma; em alguns casos, pode determinar uma ausência total de espermatozoides. O procedimento de var

12. The effect of adjuvant vitamin C after varicocele surgery on sperm quality and quantity in infertile men: a double blind placebo controlled clinical trial
Varicocele is one of the most common causes of male infertility and spontaneous pregnancy rate after varicocelectomy is only about 30%. The most important seminal antioxidant is vitamin C but recent studies about the effects of vitamin C on spermatogenesis are controversial; therefore, we decided to evaluate its role after varicocelectomy. In a double blind
