Varicose veins can cause sexual dysfunction

Varicocele

is a disease of the male reproductive system that may affect fertility but does not usually cause sexual dysfunction directly. Varicocele affects the veins around the testicles, but not the arteries and nerves associated with erection. Therefore, varicocele does not directly affect the quality and duration of a male penis erection. In addition, some patients with varicocele may experience discomfort and pain in the testicular area, which may affect libido and sexual function, but this effect is usually temporary, and sexual function will gradually recover once the related discomfort is relieved.
