n. a collection of dilated veins in the spermatic cord, more commonly affecting the left side of the scrotum than the right. It usually produces no symptoms apart from occasional aching discomfort. In some cases varicocele is associated with a poor sperm count (see oligospermia) sufficient to cause infertility. Surgical correction or radiological embolization of the varicocele in such patients (varicocelectomy) usually results in a considerable improvement in the quality and motility of the sperm, but may or may not improve the number of pregnancies and live births thereafter.
