Physical Problems A variety of physical problems can cause male infertility.  These problems either interfere with the sperm production process or disrupt the pathway down which sperm travel from the testes to the tip of the penis.  These problems are usually characterized by a low sperm count and/or abnormal sperm morphology.  The following is a list of the most common physical problems that cause male infertility: Variocoele: A varicocele is an enlargement of the internal spermatic veins that drain blood from the testicle to the abdomen (back to the heart) and are present in 15% of the general male population and 40% of infertile men.  These images show what a variocoele looks like externally and internally.  A varicocele develops when the one way valves in these spermatic veins are damaged causing an abnormal back flow of blood from the abdomen into the scrotum creating a hostile environment for sperm development.  Varicocoeles may cause reduced sperm count and abnormal sperm morphology which cause infertility.  Variococles can usually be diagnosed by a physical examination of the scrotum which can be aided by the Doppler stethoscope and scrotal ultrasound.  Varicocoele can be treated in many ways (see treatment section), but the most successful treatments involve corrective surgery.
