- prostate gland enlarges w/age & secretions decrease
- scrotum hangs lower
- testes get smaller and more firm
- d/c testosterone
- d/c sexual function
- i/c GU cancer
- i/c incontinence
decrease in sex hormone secretion causes?
- d/c muscle strength and sexual energy
- d/c in viable sperm
- shrinking of testes
- Erectile dysfunction (ED)
- enlargement of prostate
what are the changes in sexual response to age?
- prolonged time to reach full erection
- rapid penile detumescence (d/c swelling)
- prolonged refractory time
- d/c viable sperm
- s/s of obstruction of lower urinary tract
s/s of enlarged prostate?
- increased urinary freq
- d/c force
- double, triple voiding
influencing factors of sexual dysfunction?
- physical disease (DM, MS, Stroke, Cardiac)
- meds (antiHTN, anticholinergics, psychotropics)
positive DRE and increased PSA =
- prostate specific antigen that is produced by the prostate gland
- increased in prostate cancer (over 0.4 ng/mL)
- normal 0.2-0.4
- drawn before DRE or catheterization or you will get a false negative
when is PSA elevated?
- in BPH, prostate cancer, infections of the prostate and urinary tract
- ID those at risk
- used to monitor after Tx for cancer
- transrectal ultrasound
- done after DRE
- guides needle biopsies
teaching to minimize recurrence of prostate cancer?
have regular PSA tests and repeat lymph node biopsies
surgical removal of one teste?
- collection of fluid in the tunica vaginalis (scrotum)
- repair of hydrocele- hydrocelectomy
- one hr before sex
- for ED, impotence
inflammation of the prostate gland
uncontrolled, presistant erection of the penis from either neural or vascular causes.
