Anatomy and Physiology of the
Male Reproductive System
• Spermatogenesis
• Sperm are produced in seminiferous tubules of testes from
about age 13 throughout the remainder of life
• Erection
• Parasympathetic nerves release neurotransmitters that cause
the cavernosal arteriole walls to relax
• Allows high-pressure arterial blood to flood the sinuses of the
erectile chambers, increasing blood volume and raising
cavernosal blood pressure to approximately the same as
arterial blood pressure

8
Anatomy and Physiology of the
Male Reproductive System
• Emission and ejaculation
• Stimulation of internal and external sex organs
initiates contractions of the vasa deferentia and
prostatic capsule
• Contractions move sperm to the ejaculatory ducts
and expel them into the internal urethra
• Filling of urethra excites nerves in sacral region of
spinal cord: contractions of internal genital organs,
pelvis, and body trunk and result in ejaculation
(expulsion) of semen

9
Age-Related Changes in the
Male Reproductive System
• Testosterone decreases rapidly after age 50
• Men in their late 40s and early 50s may be
slower to arouse and have a longer refractory
period between erections, but in a healthy man,
spermatogenesis and the ability to have
erections last a lifetime

intercourse
• Erection requires intact neurologic function, sufficient
inflow of blood to fill the corpus cavernosa, leakproof
storage mechanism for maintaining the erection.
Factors are
•
•
•
•
•

• Alprostadil
• Intracavernosal injection (Caverject) or urethral
suppositories (MUSE)
• Papaverine
• Testosterone
Elsevier items and derived items © 2007 by Saunders, an imprint of Elsevier, Inc.
38

• Vacuum constriction devices
• A vacuum draws blood into the penis
• Revascularization
• Surgical procedure that bypasses blocked arteries,
removes or ties off incompetent veins, and tightens
the surrounding tissue
• Penile implants
• Silicon cylinders placed in the erection chambers
that keep the penis firm at all times

Erectile Dysfunction (Impotence)
• Assessment
• Patient’s health/family history of diabetes
• Record surgical procedures, injuries, illness, cancer,
and medications used regularly
• Habits and lifestyle including daily activities, diet,
use of alcohol and illicit drugs, exercise, health care
beliefs, interpersonal relationships, capability for
self-care, age, physical condition, and educational
needs
Elsevier items and derived items © 2007 by Saunders, an imprint of Elsevier, Inc.
41
Erectile Dysfunction (Impotence)
• Interventions
• Listen and be careful not to dismiss the issue as
unimportant
• Provide factual information and resources
Elsevier items and derived items © 2007 by Saunders, an imprint of Elsevier, Inc.
42
Peyronie’s Disease
• A hard, nonelastic, fibrous tissue (plaque) just under
the skin of the penis of men between 45 and 70 years
of age
• Plaque develops as a result of an injury that causes
inflammation and scarring of the tunica surrounding the
corpora cavernosa
• Loss of elasticity of the tunica results in decreased
ability to fill during an erection and failure to store
because of low pressure on the veins against the
covering of the erectile tissue

44
Peyronie’s Disease
• Medical treatment
• Topical or oral medications with vitamin E, oral paraaminobenzoic acid, tamoxifen, colchicine
• Local radiation, injections into the lesions,
ultrasonography, and surgical correction are other
options
• Treatment depends on size of the plaque and
curvature and resultant degree of dysfunction
Elsevier items and derived items © 2007 by Saunders, an imprint of Elsevier, Inc.
45
Priapism
• Prolonged erection not related to sexual desire
• Causes
• Injury to the penis, sickle cell crisis, and neoplasms of the brain or
spinal cord
• Drugs that may be responsible include phenothiazines, alphaadrenergic blockers, anticoagulants, alcohol, cocaine, marijuana,
vardenafil (Levitra), and intracavernosal injections
• Painful; constitutes an emergency situation
• Failure to resolve the problem within 12 to 24 hours
may result in penile ischemia, gangrene, fibrosis, and
erectile dysfunction
Elsevier items and derived items © 2007 by Saunders, an imprint of Elsevier, Inc.
46
Priapism
• Medical treatment
• Aspirating blood from erectile chambers or injecting drugs that
cause contraction of smooth muscle, inhibiting inflow of blood
and allowing outflow
• If these efforts fail, emergency surgery may be needed
• Nursing care must be particularly sensitive to the
embarrassment the patient may experience
• Understanding the condition and alleviating pain are important
Elsevier items and derived items © 2007 by Saunders, an imprint of Elsevier, Inc.
47
Phimosis
• Edema that may prevent retraction of the foreskin
caused by inflammation under the foreskin
• Often associated with poor hygiene
• Treated with antimicrobials and proper cleansing
• Circumcision sometimes recommended
• Uncircumcised men need to retract the foreskin for
cleaning as part of daily hygiene
Elsevier items and derived items © 2007 by Saunders, an imprint of Elsevier, Inc.
48
Infertility
• Couples who have had unprotected intercourse
over a 12-month period and have been unable
to become pregnant
• May be caused by a reproductive problem in
the male, the female, or both
Elsevier items and derived items © 2007 by Saunders, an imprint of Elsevier, Inc.
49
Infertility
• Etiology and risk factors
• Male infertility: endocrine disorders, testicular
problems, or abnormalities of the ejaculatory system
• Infections can affect testicular and ejaculatory
function
• Drug therapy, radiation, substance abuse, and
environmental hazards also can affect the testes
Elsevier items and derived items © 2007 by Saunders, an imprint of Elsevier, Inc.
50
Infertility: Etiology and Risk Factors
• Infections
• Mumps, tuberculosis, pneumonia, and syphilis
• Chlamydia trachomatis and Neisseria gonorrhoeae
Elsevier items and derived items © 2007 by Saunders, an imprint of Elsevier, Inc.
51
Infertility: Etiology and Risk Factors
• Cryptorchidism
• Testis in other than a dependent scrotal position
• Because the abdominal cavity is warmer than the scrotum,
excessive warmth can damage the seminiferous epithelium of
undescended testes and result in decreased spermatogenesis
• Medical treatment
• If testes within normal path but do not descend or cannot be
pulled into scrotum, usually do not respond to hormonal therapy,
and surgery is needed
Elsevier items and derived items © 2007 by Saunders, an imprint of Elsevier, Inc.
52
Figure 48-10

53
Infertility: Etiology and Risk Factors
• Testicular torsion
• Occurs unilaterally when testicle is mobile and the spermatic
cord twists, cutting off blood supply to testicle
• Acute surgical emergency requiring immediate release of the
torsion or removal of the testicle
• Usually in adolescents and when the scrotum is warm and
relaxed but may occur for no apparent reason
• Symptoms: intense pain, often accompanied by nausea and
vomiting
• After testicular torsion is corrected, lowered sperm counts and
infertility may follow

55
Infertility: Etiology and Risk Factors
• Varicocele
• A lengthening and enlargement of the scrotal portion of the
venous system that drains the testicle
• Caused by incompetent or absent valves in the spermatic
venous system; allows pooled blood and the resulting
increased pressure to dilate the veins
• Treatment includes scrotal support or surgical ligation and is
indicated when fertility is thought to be affected
• Fertility or ability to conceive may/may not improve
Elsevier items and derived items © 2007 by Saunders, an imprint of Elsevier, Inc.
56
Infertility: Etiology and Risk Factors
• Vasectomy
• Surgical removal of a portion of the vasa
• Erection, ejaculation, and intercourse are unaffected
• Postoperative pain/swelling managed with application of an ice
bag, mild analgesics, and scrotal support
• Patient can resume intercourse as soon as he feels
comfortable; important to use other methods of birth control
until analysis of semen determines that there is a complete
absence of sperm
• Nursing care should include preoperative teaching about the
procedure itself and the resultant infertility

58
Penile Cancer
• Relatively rare; almost exclusively in uncircumcised men
• Risk factors: chronic irritation, poor hygiene, a history of multiple
sexual partners, sexually transmitted infection, and long-term
tobacco use
• A dry, wartlike painless growth on the penis that does not respond
to antibiotic therapy
• Can be removed surgically if treated in early stages
• Advanced stages may ulcerate and involve the foreskin and penile
shaft
• Extensive resection or amputation as well as resection of nearby
lymph nodes may be necessary
Elsevier items and derived items © 2007 by Saunders, an imprint of Elsevier, Inc.
59
Testicular Cancer
• Testicular germ cell carcinoma occurs most often in
men between ages of 18 and 34
• Three established risk factors: cryptorchidism, white
race, and previous testicular cancer
• Other factors: history of orchitis, HIV infection, and in
utero exposure to diethylstilbestrol
• Patients most often present with hard, painless tumors
