  • Chronic tobacco use - Smoking has been shown to affect arterial blood flow and may also affect the arteries in the penis, reducing the blood flow necessary to maintain an erection.
    Diabetes - This is one of the most common causes of impotence, because diabetes can cause changes in blood flow through narrowing of the arteries, or damage to nerve endings in the penis.
    Hormonal Imbalance - Only a small percentage of cases of impotence are due to hormonal problems, such as insufficient testosterone.
    Neurologic Impairment - Injuries to the spinal cord or brain, or neurological diseases, such as Alzheimer's Disease, can lead to impotence. Erectile dysfunction is commonly associated with multiple sclerosis and Parkinson's disease.
    Pelvic Surgery - Surgery or radiation to the prostrate, bladder, rectum or colon can cause nerve damage in the surrounding area. The damage may interfere with signals that must pass between the brain and the sexual organs to allow erection and orgasm.
    Pelvic Trauma - Injuries caused by accidents, particularly accidents associated with bicycle riding, water sports, gymnastics and horseback riding, can cause impotence.
    Prescription Drugs- Many prescription drugs, especially blood pressure or anti-depressant medication, can cause impotence, as well as some over-the-counter medications.
    Psychological - Depression, anxiety, problems with self-esteem, anger, fear, and other mental conditions may lead to impotence.
    Vascular Disease - Vascular diseases such as hardening of the arteries, or heart disease, can lead to reduced blood flow, thereby impairing the ability of the penis to become sufficiently engorged to maintain an erection.

    154. 154. Former Surgeon General Joycelyn Elders • In 1994, she was invited to speak at a United Nations conference on AIDS. She was asked whether it would be appropriate to promote masturbation as a means of preventing young people from engaging in riskier forms of sexual activity.

    162. 162. Undescended Testicle
    163. 163. Testicular Cancer • The first sign of testicular cancer is usually a slight enlargement of one of the testes.
    164. 164. Testicular Cancer • Pain may be absent but usually there is a dull ache in the lower abdomen and groin.
    165. 165. Testicular Self Examination (TSE) • Early detection can be done with a simple three minute monthly examination. • The best time is after a warm bath or shower when the scrotal sac is relaxed.
    166. 166. Testicular Self Examination (TSE) • The male rolls each testicle gently between the thumb and fingers of both hands. If there are any hard lumps the person should see a doctor immediately.
    167. 167. Hydrocele A hydrocele is a collection of fluid inside the area of the scrotum, surrounding the testicle. Hydroceles are common in newborn infants and normally resolve after a few months after birth. The main symptom is a painless, swollen testicle, on one or both sides, which feels like a water-filled balloon. Hydroceles are usually not dangerous, and they are usually only treated when they cause discomfort or embarrassment, or they get so large that they threaten the blood supply of the testicle.
