Abstract
Chronic testicular pain (orchialgia, orchidynia or chronic scrotal pain) is common and well recognized but its pathophysiology is poorly understood. Currently treatment is largely empirical. This article aims to present an overview of its prevalence, possible aetiology and the available treatment options. The contribution of psychological factors is unclear, although some of these patients undoubtedly are depressed. Post vasectomy chronic testicular pain may be due to functional obstruction of the vas, or to spermatic granuloma. The surgical technique used may be relevant and the application of intraoperative local anaesthetic may have a role in reducing the risk. The importance of the sympathetic nervous system and the role of a possible alteration of the adrenergic receptors of the vas deferens in patients with chronic testicular pain are discussed. For patients failing to respond to conservative treatment, microsurgical denervation of the spermatic cord, epididymectomy and vasovasostomy have all shown a degree of relief. Unfortunately a small number of patients fail to respond to both conservative and more invasive treatment methods and for them the only available therapeutic option is inguinal orchiectomy.
