  6. The Cremasteric Reflex
    • Evaluates Genitofemoral Nerve (L1-L2)
    • To Elicit: gently brush the superior medial portion of the thigh
    • Normal Response: ipsilateral contraction of the cremasteric muscle (elevation of scrotum & testes)
    • Abnormal Response: no ipsilateral contraction of the cremasteric muscle (absent). Indicates testicular torsion, L1-L2 cord injury, upper or lower motor nerve injuries, and less commonly epididymitis
    • The cremasteric reflex is almost always absent in patients with testicular torsion, and its presence may help to distinguish other causes of acute scrotal pain from testicular torsion.
    • Several studies indicate that the presence of a cremasteric reflex in the acute scrotum is unlikely to be testicular torsion.

  10. Define erectile dysfunction (ED)
    The consistent or recurrent inability of a man to attain and/or maintain an erection sufficient for sexual performance
  11. ED Prevalence
    • (MALES) study found prevalence of 16%, 22% in US (Men ages 20-75 yrs.).
    • Affects nearly 30 million American men
  12. ED as a marker of vascular disease
    Men with ED have a greater risk of a cardiovascular event than men without ED.
  13. ED and CVD
    • ED usually precedes the onset of angina by 2-3 years.
    • ED usually precedes adverse cardiovascular events by 3-5 years.
    • Men with ED should undergo a thorough cardiovascular evaluation with investigation of cardiac risk factors.
  14. Physiology of erection
    • Neurovascular phenomenon. Sexual stimulation leads to parasympathetic nervous system enhancement of production of cyclic guanosine monophosphate (cGMP) via nitric oxide.
    • Smooth muscles relax and blood flows into the penis.
    • Filling of the penis, compresses outflow of blood via the veins.
  15. Medications that may cause ED
    • Diuretics: thiazides, spironolactone
    • Anti-HTN: CCB, BB, methyldopa, clonidine, reserpine, guanethidine
    • Cardiac or cholesterol meds: digoxin, gemfibrozil, clofibrate
    • Antidepressants: SSRI, TCA, lithim, MAOI
    • Tranquilizers: butyrophenones, phenothiazines
    • H2 agonists: ranitidine, cimetidine
    • hormones: progesterone, estrogen, corticosteroids, LHRH, 5-alpha-reductase inhibitors, ciproterone acetate
    • Cytotoxic agents: methotrexate
    • Immunomodulators: interferon-a
    • Anticholinergics: disopyramide, anticonvulsants
    • Recreational drugs: alcohol, cocaine
  16. Potential causes of ED
    • Physical Causes:
    • Vascular (leading cause) marker of endothelial dysfunction,
    • Cavernosal,
    • Neurologic,
    • Hormonal Causes.
    • Psychological Factors
  17. Lab Exam for ED
    • Consider Testosterone if decreased libido.
    • Older patients (or others where indicated) do lipid panel and fasting blood glucose.
    • Targeted tests in select patients include PSA and Prolactin.
  18. Treatment for ED
    • Identify and Treat Organic Comorbidities and other risk factors.
    • Counsel and Educate the Patient and Partner.

  19. Medications for ED
    • Phosphodiesterase Type 5 (PDE-5) Inhibitors:
    • Sildenafil (Viagra)
    • Tadalafil (Cialis)
    • Vardenafil (Levitra).
  20. Use of PDE-5 inhibitors
    • All three similarly effective. 75% of men on medications have satisfactory erection to complete intercourse.
    • Still require sexual stimulation to have erection.
    • Sildenafil’s absorption may be reduced by foods – especially fatty foods.
    • Expect maximal efficacy in 1 hour (2 hours after tadalafil).
    • First few doses may not be successful – try 6-8 times before giving up.
  21. PDE-5 inhibitors Side Effects and Contraindications
    • Side effects: Headache, Indigestion, Flushing, Nasal congestion, Blue hue to vision.
    • Contraindications: Not to use with nitrates (including amyl nitrate). Not to use if severe CV disease. Cautious use of vardenafil if has prolonged QT. Care if on alpha blocking agents – may cause significant hypotension.
  22. Yohimbe
    • From bark of the yohimbine tree in Central Africa.
    • Traditionally used to treat all forms of impotence.
    • Believed to work through the Central Nervous System.
    • An alpha2 adrenoreceptor blocker.
    • Metaanalysis shows yohimbine superior to placebo.
    • Relatively safe medication
  23. Surgery for ED
    • Implantation of prosthesis (semi-rigid and inflatable).
    • Balloon dilation of proximal arteries.
    • Bypass procedure for distal artery occlusion.
    • Ligation of veins if venous problem.
  24. Lifestyle modifications
    Weight loss, Increase Exercise, Smoking Cessation
  25. Older Treatments for ED
    • Intracavernosal Injection,
    • Vacuum Constriction Devices,

  27. Classifications of prostatitis and pelvic pain syndromes.
    • Acute Bacterial Prostatitis (2-5%),
    • Chronic Bacterial Prostatitis (2-5%),
    • Chronic Prostatitis and Chronic Pelvic Pain Syndrome (CPPS) (90-95%)
    • Can be Inflammatory or Noninflammatory, Asymptomatic Inflammatory Prostatitis often found when working up men for Infertility (See WBCs in the semen).
    • Concerns of Prostate Cancer (see in biopsy).
    • No treatment needed.
  28. Acute bacterial prostatitis
    • Least common form.
    • Easiest to diagnose.
    • May be life-threatening.
    • Consider this in septic males without an obvious source of infection.
    • Risk Factors: GU Instrumentation, Anal intercourse, Immunocompromised, Other comorbid conditions (Diabetes mellitus, Neurologic disorders associated with urinary system dysfunction).
    • Pathophysiology: May be sexually acquired, May be seeded by refluxed urine, May be hematogenously spread from distant source, May be spread by the lymphatic system, May be contiguous spread from adjacent infection.
    • Signs and Symptoms: Urinary Symptoms (e.g. frequency, urgency, dysuria, nocturia, change in urinary stream). Pain (lower back, genital, abdomen of urinary retention).
    • Systemic S/S: fever, chills, nausea, vomiting, hypotension, change in LOC
  29. Organisms associated with acute bacterial prostatitis
    • Gram Negative Organisms 80% of time (E. coli, Enterobacter, Serratus, Pseudomonas, Enterococcus, and Proteus).
    • N. gonorrhea and C. trachomatis in sexually active young men
  30. Work-up for Acute Bacterial Prostatitis
    • Urinalysis and urine cultures should be obtained.
    • Can culture urethral secretions if present.
    • Testing for GC and Chlamydia as indicated.
    • If septic, blood cultures.
    • If unresponsive to Abx, consider CT for abscess.
  31. Treatment for Acute Bacterial Prostatitis
    • Does the patient need to be hospitalized for IV antibiotics? (if toxic, consider other comorbidities).
    • Pain management.
    • May need urinary diversion if retention.
    • IV Antibiotics – Broad spectrum at first.
    • Oral antibiotics – usually fluoroquinolones for 2-6 weeks.
  32. Chronic Bacterial Prostatitis
    • S/S similar but less severe than in Acute Bacterial Prostatitis.
    • Not life-threatening. Symptoms can wax and wane in the patient.
    • Think of this with recurrent UTIs in men; almost always the same organism
  33. Chronic Bacterial Prostatitis Treatment
    • Prolonged courses of Antibiotics.
    • Usually Fluoroquinolones for 4-12 weeks.
    • Some consider long term low dose fluoroquinolones in recalcitrant cases.
    • Suppressive antibiotic treatment (Consider if 3 or more recurrences each year. ¼ to ½ treatment dose given at bedtime. TMP-Sulfa, tetracycline, amoxicillin and nitrofurantoin all used.)
  34. Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CPPS)
    • Pain (urinary and/or genital) with no evidence of infection.
    • Inflammatory (presence of WBCs) and Non-Inflammatory Forms (later called Prostatodynia by some).
    • Must exclude Infection, GU Cancer, Urinary Tract Disease, Urethral Stricture, Neurologic Disease affecting the bladder.
  35. Chronic Prostatitis/CPPS
    • Pathogenesis is Unclear;
    • Theories include: Nanobacteria, Elevated Prostatic Pressures, Voiding Dysfunction, Pelvic Floor Myalgia, Functional Somatic Syndrome, Emotional Disorder.

  36. Medications that Contribute to LUTS
    • Antihistamines: decreased parasympathetic tone
    • Decongestants: increased sphincter tone via alpha-adrenergic receptor stimulation
    • Diuretics: increased urine production
    • Opiates: impaired bladder contractility
    • TCAs: anticholinergic effects
  37. Benign prostatic hyperplasia (BPH)
    • Microscopic detection of prostatic hyperplasia (benign proliferation of stroma and epithelium).
    • Palpable enlargement of the prostate (DRE or by US imaging).
    • The collection of urinary symptoms associated with prostatic hyperplasia.
    • Histologic BPH increases linearly in age.
    • Present in 50% of men at age 60 years.
    • Present in 90% of men at age 85 years.
    • Only 50% of men with microscopic findings have macroscopic findings.
    • Only 30-50% of men with macroscopic findings have symptoms.
  38. BPH Symptoms
    • Bladder Storage Problems: Urgency, Frequency, Nocturia, Urge incontinence, Stress incontinence.
    • Bladder Emptying Problems: Voiding, Hesitancy, poor flow, intermittency, straining, dysuria, Postmicturition, Terminal dribble, postvoid dribble, incomplete emptying
  39. BPH Evaluation
    • Medications,
    • DRE (est. size, shape, symmetry, consistency),
    • Abdominal exam,
    • Focused neurologic examination,
    • Post-void residual (If greater than 100 mls consider referral).
    • Labs: Glucose, Electrolytes, Urinalysis, PSA in select patients
  40. Alpha-1 Antagonists
    • Non-Selective: Terazosin (Hytrin), Doxazosin (Cardura), Prazosin (Minipres)
    • Selective: Tamulosin (Flomax), Alfuzosin (Uroxatral)
  41. Medical therapy for BPH
    • Alpha-1-adrenergic blockers: Decrease muscle tone in stroma and capsule, Address dynamic component of disease, Most rapid symptom relief.
    • Androgen hormone inhibitors (5-alpha reductase inhibitors): Reduce prostate mass, Address static component of disease
  42. Surgical Interventions for BPH
    • Indications: Renal insufficiency, Urinary retention, Recurrent UTIs, Bladder calculi, Hydronephrosis, Large postvoid residual volume.
    • Options: Transurethral resection of prostate (TURP), Transurethral incision of prostate (TUIP), Open prostatectomy, Minimally invasive surgery, Transurethral laser-induced prostatectomy (TULIP), Transurethral needle ablation (TUNA), Transurethral microwave thermotherapy, Water-induced thermotherapy, Intraprostatic stents.
    • Outcomes: Erectile dysfunction (4-10%), Urinary incontinence (0.5-1.5%), 5 year recurrence rate of 2-10%
  43. Prostate Cancer Risk Factors
    • Age, Race (AA), High Fat Diet (+/-), Family History, Genetics, Obesity.
    • Not associated with smoking, sexual activity, prior infections or BPH.
    • Risk Reduction: Well-balanced diet, Physical activity , Weight control, Chemoprevention (? Aspirin, ? statins)
  44. Signs and Symptoms of Prostate Cancer
    • None in early disease.
    • Advanced disease: Obstructive urinary symptoms (similar to BPH), hematuria, hematospermia.
    • Common sites of metastasis: Bones! Neurological symptoms from spinal cord compression, Back pain / pathologic fractures.
    • Lymph nodes –inguinal. Lower extremity lymphedema .
  45. Prostate Cancer Screening
    • DRE (digital rectal exam): Nodularity or induration. Cancer typically arises in the periphery of the prostate. Detection rate varies from 1.5 – 7% (most are more advanced tumors).
    • Serum PSA: Protein produced by healthy & malignant prostate cells. Elevated in cancer, inflammation or BPH. Not diagnostic of cancer. Will rise as men age not more than 0.75ng/mL per year. Will be elevated in 10-15% of men screened.
    • Transrectal Ultrasound: No role as first-line screening tool. Used in staging & as guidance for biopsy to improve accuracy.
  46. PSA Controversy
    • Limitations: Not yet known if it reduces mortality. False positives and false negatives.
    • Overdiagnosis: Most prostate cancers are slow-growing & can exist for decades before they are large enough to cause symptoms. Treatments aren’t without significant side effects.
  47. PSA velocity
    Serial measurement--how quickly it rises over time. >0.75 ng/mL per year = ↑ likelihood of cancer
  48. PSA density
    serum PSA/volume of prostate by US. High density = ↑ likelihood of cancer
  49. Age-specific reference ranges
    Increases sensitivity & specificity. AA men have lower age-specific reference ranges.
  50. Compare free serum and protein-bound PSA levels
    Lower % free serum PSA = ↑ likelihood of cancer
  51. Prostate Screening and the USPSTF
    • Current evidence is insufficient to assess the balance of benefits and harms of prostate cancer screening in men under age 75 (Grade: I).
    • Recommends against prostate cancer screening in men older than age 75 (Grade: D).
  52. Prostate Screening If men decide to be screened
    • Normal DRE and PSA < 2.5ng/mL, repeat in 2 yrs.
    • Normal DRE and PSA 2.5-4.0ng/ml, repeat in 1 yr.
    • Approx 50% will progress to >4.0.
    • General rule of thumb = refer if PSA >4.0ng/mL or abnormal DRE .
  53. Prostate Cancer Diagnosis
    • Abnormal DRE or elevated PSA.
    • Prostate biopsy by TRUS (Hypoechoic appearance, 8 – 12 cores are sampled from apex, mid-portion and base of both lobes, Most commonly adenocarcinoma).
    • MRI PPV of finding capsular extension and invasion to seminal vesicles is similar to TRUS. Can detect lymphadenopathy.
    • No role for CT scanning.
    • Radionuclide bone scan detects bone metastasis. Consider if PSA >20, high-grade histology or bone pain.
  54. Prostate Cancer Staging: Gleason system
    • Tissue graded 1 – 5, based on appearance of cells.
    • Grade 1 = well-differentiated.
    • Grade 5 = poorly-differentiated.
  55. Gleason score
    • Calculated by adding primary & secondary grades.
    • Primary grade >50% of sample.
    • Secondary grade between 5-50%.
    • Scores range 2 to 10.
    • Indicates tumor aggressiveness & prognosis.
    • 2-4 = low grade, uncommon in clinically detected ca.
    • 5-7 = intermediate grade, most common.
    • 8-10 = high grade/aggressive.
  56. Prostate Cancer Treatment
    • < 10 yr life expectancy: Active surveillance.
    • >10 yr life expectancy: Active surveillance.
    • Surgery: Radical prostatectomy. Open vs laparoscopic, Cavernosal nerve sparing, Local recurrence uncommon, 2% urinary incontinence, 10% stress incontinence, Follow PSA’s postoperatively (should be zero).
    • Radiation. External beam (associated with cystitis and proctitis and progressive impotence) or brachytherapy (radioactive seeds). Other: hormonal therapy and cryotherapy.
  57. Prostate Cancer Advanced & Metastatic Disease Tx
    • Hormone therapy is mainstay. Androgen deprivation to decrease circulating levels of androgens available to prostate cells.
    • Rapid regression in prostate size, PSA levels and Improved symptoms (bone pain).
    • Side effects: Hot flashes, Osteoporosis, Impotence, Decreased facial hair, Weight gain, Loss of muscle mass, Gynecomastia
  58. Varieties of Hormonal Therapy
    • Luteinizing hormone-releasing hormone (LHRH) analogues (Lupron) Works at level of pituitary/hypothalamus to decrease testosterone production.
    • Antiandrogens (flutamide, bicalutamide) Can be used in conjunction with LHRH agents. Blocks prostate cell metabolism of androgens.
    • Ketoconazole, steroids Function to block adrenal androgen production.
  59. Penile Cancer
    • Rare in developed countries.
    • Neonatal circumcision reduces risk.
    • Squamous cell is most common.
    • Retract foreskin on PE…you must uncover to discover!
    • Prompt urological referral for biopsy of suspicious lesions.
    • Symptoms: Painless, non-indurated, ulcerated mass. Infection of lesion is common.
    • Location: glans penis, coronal sulcus, foreskin. Inguinal adenopathy. Begins as small lesion on the glans or prepuce that is non-healing, Subtle induration. Obscured by foreskin and can grow undetected. Untreated cases may result in auto-amputation.
    • Surgery: “gold standard” for rapid definitive treatment of the primary tumor. Penile or glans-sparing procedures with low grade tumor. Range of procedures from minimally invasive to total penectomy.
  60. Testicular Cancer
    • Most common solid tumor in men age 15-34.
    • Slightly more common on right vs left. 90-95% are germ cell tumors.
    • Risk Factors: Cryptorchidism /undescended testicle (5%), 5-10% will occur in unaffected testicle, Surgery doesn’t alter risk, Highest risk for intra-abdominal testis, Lowest for inguinal testis.

    • Pathology: Vast majority are germ cell tumors.
    • Staging: Serum tumor markers, B-HCG, AFP, LDH. HCG elevated in choriocarcinoma, embryonal carcinoma and 15% of seminomas. AFP elevation excludes diagnosis of seminoma. Secreted either by primary tumor or metastasis.
    • CT scans—chest, abdomen, pelvis. Retroperitoneal lymph nodes are most common site of regional metastasis. Lungs & mediastinum most common distant mets.
  64. Inguinal Orchiectomy
    • High ligation of the spermatic cord. Tumor markers are evaluated prior to orchiectomy.
    • Should decrease post-op.
    • ↑ STM post-orchiectomy requires chemotherapy.
  65. Seminomas
    • Radio-sensitive.
    • Stage I & IIa need retroperitoneal radiation.
    • Bulky Stage IIb & III need chemotherapy.
  66. Non-seminomas
    • 75% of Stage I are cured by orchiectomy alone.
    • Many can be monitored closely for recurrence.
    • Majority diagnosed at more advanced stages.
    • Platinum-based chemotherapy is standard.
  67. Testicular Cancer Prognosis
    • Testicular cancer is often curable.
    • Consider sperm banking prior to treatments.
    • Seminomas: up to 98% alive at 5 years in early stages, 55-80% in advanced disease.

    • Abrupt/high fever accompanies orchitis.
    • Testicular swelling and tenderness (unilateral in 75% of cases).
    • Testes most common extrasalivary site of disease in adults.
    • Develops 7-10 days after the onset of parotitis in about 25-40% of postpubertal men.
    • Sterility rare. Higher with bilateral orchitis.
    • Tx: Treated symptomatically with bed rest, NSAIDs, testicular support, ice packs. Pain relief may require opioids. Injecting spermatic cord with 1% procaine solution. Admit if priapism or severe pain.
    • Etiology: Usually N. gonorrhoeae or C. Trachomatis in sexually active heterosexual men < 35 years. Enterobacteriaceae > 35 years (older men with voiding dysfunction).
  69. Epididymitis
    • Common inflammatory/infectious condition that can be acute, subacute or chronic. Subsequent to STI or urinary tract infection (UTI), irritative urine reflux in acute or chronic states.
    • Complications: oligospermia (low sperm count) and infertility.
    • Associated conditions: urethritis and hemospermia (blood in seminal fluid).
  70. Acute bacterial epididymitis
    • Relatively rare and can cause serious illness.
    • Subacute presentation is more typical.
    • Symptoms: Severe swelling, Exquisite pain involved side, High fever, Rigors, Irritative voiding symptoms.
    • Cause: Commonly seen in conjunction with acute prostatitis (in older men). Recent instrumentation is a risk factor. Prepubertal boys who present with recurrent epididymitis should be evaluated for structural abnormality of the urinary tract. Chlamydia trachomatis most common organism in men under age 35. E. coli> 35.
    • Risk factors: Sexual activity, Heavy physical exertion, Bicycle or motorcycle riding.
    • Tx: Treatment varies according to severity. Acutely febrile, septic, hospitalization for IV fluids, parenteral antibiotics. Less severe treated with oral antibiotics. Ice, scrotal elevation, NSAIDs. Prevention of sexually transmitted infections.
  71. Noninfectious epididymitis
    Thought to occur due to reflux of urine through the ejaculatory ducts and vas into epididymis producing a chemical inflammation with resultant swelling causing ductal obstruction. Typical inciting factors include prolonged periods of sitting, vigorous exercise. Treatment conservative with scrotal support, rest, NSAIDs and possibly antibiotics.
  72. Hydrocele
    • Fluid collection in scrotum or spermatic cord. Pain secondary to size.
    • CC: scrotal mass (may be asymptomatic).
    • PE: soft, painless, cystic scrotal mass usually anterior to testis, occasionally bilateral, transilluminates.
    • Tx: usually unnecessary
  73. Varicocele
    • Dilated vein of spermatic cord.
    • More common on left side.
    • Valve insufficiency in ipsilateral gonadal veins.
    • Oligospermia and/or asthenospermia (weak sperm—increased temperature).
    • Occasionally painful, dull, heavy sensation in scrotum.
    • Infertility.
    • Increased symptoms with prolonged standing and improvement when supine.
    • “Bag of worms” appearance Increases with Valsalva and decreases in supine position.
    • Symptomatic treatment with scrotal support, analgesics.
  74. Torsion of appendix testis

  75. Testicular Torsion
    • Surgical emergency! Correction within 4-6 hours.
    • Pubertal boys (12-15), early adults (19-22).
    • Torsion significantly more common in cold season.
    • Cause: Rapid movement or physical trauma. Sudden twisting of spermatic cord (usually twists internally). Strangulation of vessels and infarction.
    • Symptoms: Patient presents with scrotal pain, nausea, vomiting, abdominal pain. Awaking with scrotal pain in the middle of the night (particularly in children).
    • PE: Tender testicle, may have scrotal swelling or tender epididymis. Elevated testis (high-riding testis on affected side). Scrotal edema, possible discoloration. Prehn’s sign is not reliable (elevation of testicle leading to change in pain to differentiate from epididymitis). Absent cremasteric reflex most sensitive physical finding for diagnosing testicular torsion.
    • Diagnostics: Color Doppler ultrasound useful adjunct in evaluation of acute scrotum when physical findings are equivocal.
    • Prognosis: time available for testis salvage decreases with increasing number of turns (about 6 hours with 1 turn, 2 hours with 3 turns).
  76. STIs in Males
