A varicose vein in the scrotum is a reflection of varicoceles, which are enlarged veins that drain the testicle on that side of the scrotum.
Varicoceles can result in poor sperm parameters resulting in male subfertility. Waste products are not carried away efficiently from the testicle in these dilated or enlarged veins and result in oxidative stress on the testicle hence affecting the quality of the sperms produced. Men with varicoceles will also have an increased temperature in the testicle and heat also results in low-quality sperms.
Studies have shown that varicocelectomy or surgery to tie up these enlarged veins can improve semen parameters.
