The Male Reproductive System

Objectives

• State (What is) the role of the male reproductive system

• Describe (What is) the function of each of the organs of the male reproductive system

• Summarize (What are) the problems that can occur with the male reproductive system

• List (What are) the things a male can do to keep his reproductive system healthy

Key Vocabulary Words & Definitions

• Sperm - the sex cell produced by the testes & needed to fertilize an egg

• Egg (Ovum) - the sex cell produced by the ovaries & can be fertilized by sperm

• Testes (Testicle) - male reproductive organ that makes sperm & testosterone

Key Vocabulary Words & Definitions

• Fertilization -the process by which a sperm & an egg w/their genetic material join to create a new human life

• Reproduction – the process of producing a new human being

Key Vocabulary Words & Definitions

• Semen - a fluid made up of sperm & other secretions from the male reproductive organs

• Ejaculation – the release of semen through the urethra

The PenisThe Male Reproductive Organ That:

• Removes urine from the body

• Delivers sperm to the female reproductive organs

• Is erect during ejaculation

• Can ejaculate while sleeping called “wet dreams”

Key Vocabulary Words & Definitions

• Glans – the tip (head) of the penis; made up of nerve endings that make it extremely sensitive

• Shaft – the rest of the penis

• Circumcision – removal of the foreskin; often done for religious/cultural reasons

What Is Puberty & What Happens To The Body?

Begins between 12-14 years old Hair growth (face, chest, arm pit, pubic) Shoulders broaden Voice deepens Penis grows… Sometimes Testicles produce sperm and

testosterone The sex drive begins…

What Does The Male Reproductive System Do?

• The male reproductive system works to produce sperm and deliver it to the female reproductive system.

The Path Of The Sperm

How the Male Reproductive System Works The male reproductive system is made up of internal

and external organs.

Testes (testicles)

– Makes sperm (hundred million sperm/day)

– Makes testosterone (major sex hormone of male)

– Rests in the scrotum (keeps the sperm cooler than normal body temperature)

The Path Of The SpermEpididymis

• Sperm travels from testes to the Epididymis where they finish their development;

• Sperm stays in the Epididymis for 6-10 days;

The Path Of The SpermVas Deferens

• From the Epididymis, sperm travels through the Vas Deferens waiting to be ejaculated;

• Sperm will live for up to 6 weeks before they disintegrate

The Path Of The SpermSeminal Vesicles

• Produces a thick secretion that helps sperm move easier

• Produced at the beginning of an orgasm as sperm is being released

The Path Of The SpermProstate Gland

• Secrets a thin, milky fluid that protects the sperm from acid in the female reproductive system

• Fluid is no longer sperm, now it is semen

The Path Of The SpermThe Bulbourethral or Cowper’s

Gland & Urethra • Cowper’s Gland -

Secrets a clear fluid that protects the sperm from acid in the male urethra

• Urethra - The canal through which urine and semen leaves the body.

Problems of the Male Reproductive System

Problem What Is It ? Symptoms Treatment

Jock Itch Fungal infection of groin area

Itchy rash in groin

Keeping area cool and dry

bladder

Burning during

urination

Antibiotics prescribed by

a doctor

Bulging of the intestines or

other structure through a

weakness in the abdominal

wall

Abnormal bulge in the abdomen, groin, or scrotum

Immediate medical care

Problem What Is It ? Symptoms Treatment

happen during physical activities

Elevation of a testes,

swelling & tenderness, nausea or vomiting

Immediate medical care; if not, testes may need to be removed

moving from the abdomen to the scrotum during

fetal development

One or no testes in the

scrotum

Surgery or hormone therapy

may be hereditary

Difficulty, burning, or blood from urinating or defecating –

or no symptoms

Surgery, radiation, &/or chemotherapy

Testicular Cancer

15 – 35 yr. olds

Abnormal division of cells in the testes;

may be hereditary

Lump on testes,

enlargement of testes, sense of

heaviness, or no symptoms

Surgery, radiation, &/or chemotherapy

6 Ways To Keep Healthy

1. Wear appropriate protective gear when playing contact sports.

2. Avoid wearing tight clothing.3. Wash the penis & scrotum every day, &

dry yourself carefully after showering.4. If you are not circumcised, wash

underneath the foreskin.5. Perform a monthly testicular self-exam.6. Have an annual checkup w/a doctor.

Preventing Problems

Watch for any changes or symptoms that might indicate a problem.

If any symptoms or problems are present, see the doctor right away.

Preventing Jock Itch

• A fungal infection in the groin area.• Physically active males in hot & humid locations

are more likely to get jock itch.• Can usually prevent jock itch by wearing cotton

clothing & by drying themselves thoroughly after a shower.

• It is important to avoid wearing damp clothes for too long

• Avoid sharing towels or clothes w/others.

Preventing Trauma

• Injuries due to an external force

• Injuries can happen playing sports, from car or bicycle accidents, or during “horseplay”.

• One way to reduce the risk of traumatic injuries to the testes is to wear protective gear when playing sports.

Preventing Hernias

• When a piece of the intestine bulges into a weak place in the wall of the abdomen or groin.

• Caused by straining to lift or push something heavy.

• Can occur when coughing or sneezing.• Doctors check for signs of a hernia by feeling

for bulges in the groin while a male coughs.• Avoid strenuous lifting • Use your knees, not your back to when lifting

heavy objects.

Preventing Infertility

• Inability to fertilize an egg

• Infertility can be genetic

• It can be caused by environmental conditions such as heat & trauma to the testes.

Testicular Self-Exam1. Each month, perform the self-

exam during or after a warm bath or shower

2. Stand in front of the mirror, and hold the penis out of the way

3. Examine each testicle separately

4. Look and feel for any lumps or any change in the size, shape, or consistency of the testicle

5. Contact your doctor if you detect any troublesome signs

Early Detection Of Prostate Cancer

• Occurs mainly in older males

• Regular exams can detect prostate cancer early.

• Treatment is most effective when prostate cancer is detected early

• Delaying doctor’s exams &/or treatment can be deadly.

Section 2.1 Review

Using Key Terms

• Identify the key term for “the sex cell that is produced by the testes & that is needed to fertilize an egg.

• Sperm

• Define the term testes.

• The male reproductive organ that makes sperm & testosterone.

Understanding Key Ideas

• What are the functions of the male reproductive system?

• To produce & deliver sperm to the female reproductive system.

• What are the functions of the penis?

• Removes urine from the body &• Deliver sperm to the female reproductive

system

What is the path of the sperm through the male reproductive organs?

• Testes• Epididymis• Vas Deferens

– Seminal Vesicles– Prostate Gland– Bulbourethral

(Cowper’s) Glands

• Urethra• Penis

Compare The Symptoms Of Testicular Cancer W/Inguinal Hernia

• Testicular Cancer• Unusual lumps• Enlargement or

feeling of heaviness or fullness in the scrotum

• Inguinal Hernia• Abnormal bulge in the

abdomen or groin• Sense of heaviness,

pain, or fullness

List Ways A Male Can Keep His Reproductive System Healthy

Wear protective gear when playing contact sports.

Avoid wearing tight clothing.

Wash the penis, underneath the foreskin & scrotum every day,

Dry yourself carefully after showering.

Perform a monthly testicular self-exam.

Have an annual checkup.

Look for changes or symptoms that might indicate a problem.

If any symptoms or problems are present, see the doctor right away.

Critical Thinking

1. Why do you think the male reproductive system produces so many sperm cells?

2. How might the male reproductive system be affected if the seminal vesicles did not function?
