Complications

A spermatocele is unlikely to cause complications.

However, if your spermatocele is painful or has grown so large that it's causing you discomfort, you might need to have surgery to remove the spermatocele. Surgical removal might damage the epididymis or the vas deferens, a tube that transports sperm from the epididymis to the penis. Damage to either can reduce fertility. Another possible complication that can occur after surgery is that the spermatocele might come back, though this is uncommon.
