The higher blood pressure on this side increases the likelihood of swelling in a weakened vein. By contrast, the right testicular vein is usually shorter. For this reason, varicoceles of the right testicle are uncommon. The most common symptom of a varicocele is a dull, constant ache or persistent sensation of heaviness in the testicle. This is caused by the unrelieved pressure against the well of the weakened varicose vein.
Some men say the problem is most noticeable when they have been standing for a prolonged period.
Often, the patient will report that his discomfort is minimal when he first gets up in the morning, but increases toward the end of the day. Some men say their pain diminishes when they lie down. In others, particularly those in whom the condition develops gradually over an extended period of time, patients may assume this shrinkage or discomfort is in some way associated with aging. Others may wrongly attribute the onset of pain to muscular strain, such as from heavy lifting. All men should be aware that any recurrent or constant discomfort or pain in the genital region is abnormal and should see their urologist or primary care physician as soon as possible.
