Deformed sperm. Coloured scanning electron micrograph of a deformed sperm at centre left. It is characterised by an abnormal cytoplasmic extrusion on the spermatozoon's head. Deformed sperm may lead to male infertility; defects in the sperm may be due to a blockage of the spermatic tubes or to damage to the spermatic ducts,usually caused by a sexually transmitted disease. A varicocele,varicose veins in the scrotum,may also be a factor in deformed sperm. Other causes for male infertility include a zero production of sperm (azoospermia) or a failure to deliver sperm into the vagina (impotence).
