Men’s Reproductive System
1. Prostate gland: Produces a fluid which forms part of the semen (the liquid which appears as ejaculate)
2. Seminal vesicles: Sit at the back of the prostate gland; produce the thick milky fluid of the semen
3. Vas deferens: Tube which carries sperm from the testicles to the urethra
4. Scrotum: Sac which hold the testicles
5. Urethra: Tube which carries urine from the bladder and semen through the penis
6
Men’s Reproductive System
6. Penis: Made up of spongy tissue which fills with blood during an erection
7. Foreskin: Covers the glans and can be pulled back for cleaning - this is removed when a man is circumcised
8. Glans: Helmet shaped head of the penis
9. Epididymis: Area where sperm are stored in the testicles
10. Testicles: Produce sperm and the male sex hormone testosterone

„
Inflammatory reaction of the epididymis caused by either an infectious agent or local trauma
„
Exclusive to males of all ages, but usually found in sexually active men or older males
„
> 600,000 case reported yearly

prostate, bladder, kidney, etc.)
„
Quick onset (< 24 hours)
Other (Non-Bacterial) Epididymitis
„
Viral: usually with a very quick onset
„
Trauma: initially not associated with fever and generalized symptoms
„
Idiopathic: unknown cause, usually not associated with fever; perhaps caused by rupture of the
sperm ducts, causing sperm to leak into the tissue

„
In sexually active men: Active agents against N. Gonorrhoeae and Chlamydia should always be included in treatment
„ Ceftriaxone 250 mg IM single dose +
Doxycycline 100 mg PO BID x 10 days
Azithromycin 1 gm PO single dose
„
If > 35 years of age (older men), consider:

„
Possible agents:
„
„
„
Trimethoprim Sulfamethoxizole (Bactrim)
Ofloxacin
Ciprofloxacin
„
Chronic: Finasteride (Proscar) – lowers the amount of testosterone; prostate shrinks; SE: less interest in sex and
erectile/ejaculation problems
„
Sitz bath TID for 30 minutes each treatment
„
No sexual intercourse until acute phase resolves
27
Balanitis
28
Balanitis
Inflammation of the superficial tissues of the penile head (glans penis)
Exclusive to males of all ages, especially sexually active men
„ Uncircumcised men are more at risk for balanitis due to the presence of the foreskin
„ Most of the organisms associated with balanitis are already present on the penis, but in very small
numbers
„
„

Balanitis
Symptoms of Balanitis
„
Itching and tenderness
„
Pain, local edema and dysuria
„
Urethritis with or without discharge
„
Painful erection with altered sexual function
„
Rarely: severe ulcerations which may lead to superimposed bacterial infections
„
Rarely: lymph node enlargement
Balanitis: Causes & Risk Factors
Poor hygiene
„ Sexual contact
„ Urinary catheters
„ Trauma (frictional or accidental wounds)
„ Allergic reaction to chemical irritants (e.g., soap, lubricant jelly, condoms, etc.)
„ Allergic reaction to medications
„ Obesity
„
32
33
Types of Balanitis
„
Candidal
„
Trichomonal
„
Mycoplasma
„
Chlamydial
„
Anaerobic
Candidal Balanitis
Most common type
„ Frequently follows intercourse with an infected partner
„ Also occurs without sexual contact in diabetic patients or patients taking oral antibiotics
„ Recurrent candidal balanitis causes fissuring of the prepuce, with fibrosis and sclerosis
„
34
Treatment
Pharmacologic:
„ Analgesics
„ Ointment & Creams
„ Topical corticosteroids
„ Antibiotics
35
Balanitis: Non-Pharmacologic Treatment
„
Hygiene:
„
9.3.42
Retraction and bathing of prepuce several times daily
„
„
Warm sitz baths:
„
„
If a Foley catheter is used: strict catheter care
Ease edema and erythema
Circumcision:
„
„
Consider if symptoms are severe or recurrent
May be necessary if phimosis or meatitis occurs
„
36
Note: Severe phimosis may require prompt slit drainage, if unable to void
Pharmacologic Treatment: Analgesics
„
Acetaminophen: for minor pain and fever caused by the skin irritation and infection
AND/OR
„
37
Codeine: for patients with more severe cases or low pain threshold
Pharmacologic Treatment
„
Clotrimazole 1% cream: topical cream; kills fungi and yeasts by interfering with their cell membranes
„
„
Applied to affected areas TID
Bacitracin ointment: Topical antibiotic used to treat and prevent bacterial infections.
>Applied to affected areas 3 to 4 times daily
„
Topical Corticosteroids: QID for severe dermatitis
„
38
Balanitis: Considerations
„
„
„
„
39
40
41
Betamethasone: apply thin film BID
Always assess for evidence of other STDs in sexually active men
If lesions do not heal, refer for biopsy (i.e., pre-malignant/malignant lesions, carcinoma of the penis, etc.)
When possible, always treat underlying cause to avoid future recurrences
Even though uncircumcised men are at a higher risk, there is no significant difference in the rate of occurrence,
compared to those who are circumcised
Benign Prostatic Hypertrophy (BPH)
Benign Prostatic Hypertrophy (BPH)
„
Progressive, benign hyperplasia of prostate gland tissue
„
By 50 years, ~ 50% of men
„
By 80 years, ~ 80%-90% of men
„
Etiology is unknown
„

48
BPH – Management
„
„
„
Observe: Watchful waiting
Consult/refer as needed
Medications to decrease bulk and/or tone of gland
„
„
„
9.3.42
Alpha-blockers
5-alpha-reductase inhibitors
Combination therapy
„
„
„
49
Herbal preparations (saw palmetto?) – not FDA regulated
Minimally invasive procedures (numerous)
Surgery
BPH Pharmacotherapy
Alpha adrenergic blockers
50
„
Originally developed to treat HTN
„
Relax smooth muscle in the prostate and around the bladder neck
„
Similar efficacy
„
Best for normal-sized to moderately enlarged prostates
Alpha adrenergic blockers
„
„
See effects within ~ 1-2 days (increased urinary flow; urinate less often)
Often 4 to 6 point decrease in urinary symptom index score
Major Side Effects:
„
„
„
„
„
„
51
Decreased ejaculate
Low blood pressure
Dizziness
Headache
Stomach or intestinal irritation
Stuffy nose
Alpha adrenergic blockers
Warnings/Considerations:
„
Risk of intraoperative floppy iris syndrome (IFIS) in patients taking tamsulosin (Flomax) or others
„
52
53
9.3.42
IFIS – characterized by the iris not responding appropriately during cataract surgery
„
Can lower blood pressure to unhealthy levels when taken with erectile dysfunction drugs such as sildenafil (Viagra), vardenafil
(Levitra) and tadalafil (Cialis)
„
Follow up every 3-6 months during the first year of therapy
Enzyme (5-alpha-reductase) inhibitors for BPH
„
Shrink the prostate
„
Reduces the amount of testosterone that turns into dihydrotestosterone (DHT), a hormone required for prostate gland growth
„
Attaches to receptors on the prostate cells; encourages them to grow/multiply
„
Inhibitors reduce the prostate's "appetite" for DHT by reducing the number of receptor sites where DHT can attach
5-alpha-reductase inhibitors
for BPH
„ Equally effective
„
Take longer to work ~ 3 – 6 months
„
More costly than alpha blockers
„
Increase urine flow rate
„
Reduce urinary symptom index scores by an average of 3 points
54
5-alpha-reductase inhibitors
for BPH
„
With moderate disease to severe disease, may significantly decrease the need for surgery and the incidence of
urinary retention
Major Side Effects:
Erection problems
„ Decreased sexual desire
„ Reduced semen release during ejaculation
„ Side effects may cease when meds are discontinued or after ~ 1 year of therapy
„
55
56
How safe are the newer 5-alpha-reductase inhibitors?
Dutasteride (Avodart)
Contraindications:
„ Women and children
„ Patients with known hypersensitivity to 5-reductase inhibitors
Warnings/Precautions:
„ Dutasteride is absorbed through the skin
„ Women who are pregnant or may be pregnant should not handle Avodart Soft Gelatin Capsules because of the possibility of
absorption of dutasteride and the potential risk of a fetal anomaly to a male fetus (feminization; decreased anogenital distance,
nipple development, hypospadias)
„ Women should use caution whenever handling; if contact is made with leaking capsules, the contact area should be washed
immediately with soap and water
57
58
Dutasteride (Avodart)
„
Men being treated should not donate blood until at least 6 months have passed following their last dose.
Purpose: prevent administration of dutasteride to a pregnant female transfusion recipient
„
Hepatic impairment – not studied
„
PSA reestablished after 6 months – isolated should be doubled after 6 months for comparison to prestudy
baseline
Dutasteride (Avodart)
Adverse events:
„ Impotence
„ Decreased libido
„ Ejaculation disorders
„ Gynecomastia
59
9.3.42
Alpha blockers + 5-alpha-reductase inhibitors
Combination Therapy for BPH
„
Most tested: doxazosin + finasteride
„
One study found this combination to significantly reduce the risk of further prostate enlargement to the point
where invasive surgery was not needed
60
„
Works best for those with large prostates and high PSAs
„
Side effects – assumed similar to the combination effect (not significantly studied)
Saw palmetto
„
„
„
„
„
Medicinal element taken from the partially dried ripe fruit of the American dwarf palm tree
Studies shown effectiveness in reducing BPH symptoms
Appears to have efficacy similar to that of finasteride
No known drug interactions
Not FDA regulated
(Gordon & Shaughnessy, 2003)
61
Prostate Cancer
62
PROSTATE CANCER
63
„
Most common form of cancer, other than skin cancer, among men in the United States
„
# 2 cause of cancer-related death among men
„
About 70% of all diagnosed prostate cancers are found in men aged 65 years or older
„
Over the past 20 years, the survival rate for prostate cancer has increased from 67% to 97%
„
Death rate higher for African-American men than for any other racial or ethnic group
„
Cause unknown; High-fat diets are implicated
Symptoms

Erectile Dysfunction
Erectile Dysfunction (ED)
Inability to achieve and sustain an erection suitable for sexual intercourse
„ ~ 52% of men aged 40-70 have ED
„ ~ 5% of 40-year-old men and
15-25% of 65-year-old men
experience ED on a long-term basis
„ Not considered “normal” at any age!
„
69
What Causes Erectile Dysfunction?
„
For an erection to occur:
„
„
„
Nerves to the penis must be properly functioning
Blood circulation to the penis must be adequate
Must be a stimulus from the brain
Common causes: atherosclerosis, nerve diseases, psychological factors/stress, depression,
performance anxiety, penile injury and medications
Causes of ED: Diuretics & Antihypertensives

Erectile Dysfunction: Treatment
„
Medication choices:
„
sildenafil (Viagra)
„
vardenafil (Levitra)
„
tadalafil (Cialis)
…known as the
phosphodiesterase inhibitors
77
Phosphodiesterase (PDE) inhibitors
„
9.3.42
Prevent the breakdown of nitric oxide, a chemical messenger that promotes relaxation and opening of the blood
vessels that supply erectile tissue in the penis
78
79
„
Under the influence of nitric oxide, these vessels expand and stay dilated
„
Increased blood flow makes erectile tissue swell and compress the veins that carry blood out of the penis,
resulting in a full erection
Phosphodiesterase (PDE) inhibitors
Erectile Dysfunction:
BREAKING NEWS
New ED Drugs On The Way!
(DeNoon & Chang, 2006)
80
„
One works fast
„
One lasts long
„
One promises to be the next best thing to a cure!
Erectile Dysfunction
Near a Cure for Erectile Dysfunction?
81
„
For now, it is called hMaxi-K
„
Suitably enough for an erection treatment, it is a form of gene therapy called naked DNA
„
Its DNA carries a human genetic code into target cells
„
When the cell reads this code, it makes a protein. In the case of hMaxi-K, it is a protein that tells smooth muscles to relax
Erectile Dysfunction
„
First human trial (Melman, 2006) reported 11 men with erectile dysfunction received injections of the gene
therapy directly into the penis
„
Because this was the first human study, the doses used were smaller than those expected to have a true effect on
erections
„
The study was successful in two ways:
„
„
82
It was safe
Two men who received higher doses of hMaxi-K had greatly improved erections -- which occurred only during sexual arousal
-- for six months after a single treatment!
Erectile Dysfunction
Additional Findings:
83
„
Sex doesn’t have to be planned – allows one to get a normal erection whenever aroused
„
hMaxi-K will also be effective for a wide range of diseases that arise from the failure of smooth muscle to relax
„ Overactive bladder
„ Asthma
„ Irritable bowel syndrome
„ BPH
„ Premature labor
„ Premenstrual syndrome
Erectile Dysfunction
Long Acting Erection Drug, SLx-2101 (Goldstein, 2006)
9.3.42
„
Like Viagra, Cialis, and Levitra, SLx-2101 works by inhibiting an enzyme that makes smooth muscles contract
„
Unlike other approved erection drugs, SLx-2101 is two drugs in one:
„
„
„
„
84
When first taken, SLx-2101 is a powerful erection drug
While it is still working, the body begins to process it into a second drug, SLx-2101m1, also a powerful erection drug
Acts well beyond 48 hours
Interestingly, SLx-2101 improves erections not only in men with ED, but also in men already able to have erections!
(woo hoo!!)
Erectile Dysfunction
Faster, Shorter-Acting Erection Drug (Nehra, 2006)
„
Avanafil
„
Avanafil reaches maximum blood concentrations 35 minutes after it is taken
„
It has a half-life of 90 minutes (Compared with 4 hours for Levitra and Viagra and 17.5 hours for Cialis)
„
Good for personal preferences and men who take nitrate-based drugs (e.g., Nitrostat, Isordil, and Imdur)
„
Men taking a nitrate-based drug while on avanafil had less of a drop in blood pressure and less of an increase in blood pressure
than men who took the heart drug while on Viagra
