Male reproductive system disorders

• Its infections that affect the reproductive tract, which is part of

the Reproductive System

o For males these infections are at the penis, testicles, urethra or

the vas deferens.

o The course of these disorders could be bacterium, virus, fungus or

other organism.

o Some infections are easily treatable and can be cured, some are

more difficult, and some are non-curable such as AIDS and herpes

Common disorders of the male reproductive system

• Testicular cancer
• Prostate disorders

o Prostate cancer

• Erectile Dysfunction
• Sexually transmitted diseases

STEP 3: Explanation of the Common Disorders of the Male Reproductive

System (25 minutes)

• Testicular cancer

o It is the most common cancer in males between the ages of 20 and 35.

o An early sign of testicular cancer is a mass in the testis

• Prostate disorders

o Because the prostate surrounds part of the urethra, any infection,

enlargement, or tumour can obstruct the flow of urine.

o Acute and chronic infections of the prostate are common in

postpubescent males, often in association with inflammation of the

urethra.

o Symptoms may include fever, chills, urinary frequency, frequent

urination at night, difficulty in urinating, burning or painful

urination, low back pain, joint and muscle pain, blood in the urine,

or painful ejaculation

o Prostate cancer

▪ Is the leading cause of death from cancer in men
▪ Treatment for prostate cancer may involve surgery,

cryotherapy, radiation, hormonal therapy, and chemotherapy

• Erectile Dysfunction

o Erectile dysfunction (ED), previously termed impotence, is the

consistent inability of an adult male to ejaculate or to attain or

hold an erection long enough for sexual intercourse.

o Many cases of impotence are caused by insufficient release of

nitric oxide (NO), which relaxes the smooth muscle of the penile

arterioles and erectile tissue.

o Other causes of erectile dysfunction include

▪ Diabetes mellitus, physical abnormalities of the penis,
▪ Systemic disorders such as syphilis,
▪ Vascular disturbances (arterial or venous obstructions),
▪ Neurological disorders
▪ Surgery
▪ Testosterone deficiency
▪ Drugs (alcohol, antidepressants, antihistamines,

antihypertensive, narcotics, nicotine, and tranquilizers).

▪ Psychological factors such as anxiety or depression, fear of

causing pregnancy, fear of sexually transmitted diseases

• Sexually transmitted diseases

o The sexually transmitted diseases of the male reproductive system will

be discussed with the sexually transmitted diseases of the female

reproductive system

STEP 5: Key Points (5 minutes)

• The common disorders of the male reproductive system are testicular

cancer, prostate disorders, erectile dysfunction and sexually transmitted

diseases

• Erectile dysfunction is a big problem to the society and is caused by a

number of factors.

STEP 6: Evaluation (5 minutes)

• Define male reproductive disorder
• List common disorders of the male reproductive system.
• What is the early sign of testicular cancer?
• What are the causes of erectile dysfunction?
