Adult varicocele

Purpose of review Adult varicocele presents a challenge for male reproductive specialists. We have yet to fully elucidate the pathophysiology of varicocele. The enigma of the varicocele, although a source of frustration for clinicians, has been a siren call for researchers as attested to by the substantial, if flawed body of literature on the topic. We critically review recent publications on varicocele, Recent findings Although yielding mixed results, studies this year have explored the potential relationship between oxidative stress and varicocele-associated infertility. In clinically focused research, one group tackled the contentious question of efficacy of surgical varicocele management. Building on the errors of prior meta-analyses, this study takes a fresh view on an old but vital topic. Finally, it is becoming clearer that varicocele affects Leydig cell function as well as seminiferous tubular function, and is a risk factor for androgen deficiency. Summary With exceptions, recent studies support a role for varicocelectomy in the management of infertile couples. In addition, evidence is accumulating that early repair of varicoceles, especially large varicoceles, may be effective in preventing future infertility and may be an effective treatment for androgen deficiency.
