Varicocele is an abnormal dilatation and tortuosity of the internal spermatic veins within the pampiniform plexus of the spermatic cord [1]. The reported prevalence of varicocele varies; however, it is generally estimated at approximately 15% [2]. Although most men remain asymptomatic, the most common clinical symptoms include infertility and chronic scrotal pain [1]. Varicocele is a major cause of impaired spermatogenesis and the most common correctable cause of male infertility [3]. It is found in approximately 40% of men with primary infertility and in 80% of men with secondary infertility [4]. About 2% to 10% of men with varicocele complain of pain, mainly in the scrotum or in the inguinal area [5]. Varicocelectomy for male infertility has been investigated far more than pain. The cause of pain due to varicocele is not well understood. Hence, we conducted this review focused on pain in varicocele.
ETIOLOGYThe etiology of pain associated with varicocele is not completely understood. However, infertility due to varicocele is a possibility, as varicocele affects spermatogenesis and the function of Leydig cells, by increasing the testicular temperature, venous pressure, hypoxia, Varicocele is the dilatation of the scrotal portion of pampiniform plexus and the internal spermatic venous system. About 15% of men suffer from scrotal varicocele and 2% to 10% of them complain of pain. The probable mechanisms for pain include compression of the surrounding neural fibers by the dilated venous complex, elevated testicular temperature, increased venous pressure, hypoxia, oxidative stress, hormonal imbalances, and the reflux of toxic metabolites of adrenal or renal origin. Testicular pain associated with varicoceles is typically described as a dull, aching, or throbbing pain in the testicle, scrotum, or groin; rarely, it can be acute, sharp, or stabbing. The management of testicular pain associated with varicocele starts with a conservative, non-surgical approach and a period of observation. Varicocelectomy in carefully selected candidates with clinically palpable varicocele resolves nearly 80% of all cases of testicular pain. Microsurgical techniques for varicocelectomy have gained popularity with minimal complication rates and favorable outcomes. The grade of varicocele, the nature and duration of pain, body mass index, prior conservative management, and the type of surgical method used, are predictors for the success of varicocelectomy.Keywords: Pain; Review literature as topic; Surgical procedures, operative; Varicocele This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/4.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.
