Men's Health Flashcards
Endocrine hormone influences
- Lutenizing hormone –> stimulates production of testosterone
- Follicle-stimulating hormone –> testicular growth & sperm maturation
- Estrogen –> converted from testosterone to aromatase
- Testosterone
Hypogonadism
Diminished functional activity of the gonads & diminished sex hormone production
- Primary: chemo/radiation, autoimmune, genetic, infection
- Central: poor nutrition, steroids, pituitary injury, alcoholism
Hypogonadism symptoms
- loss of body hair
- muscle loss
- abnormal breast growth
- reduced growth of penis & testicles
- erectile dysfunction
- osteoporosis
- low or absent sex drive
- infertility
- fatigue
- hot flashes
- difficulty concentrating
- decreased libido
Testosterone
Class: androgen
Indication: expression of male sex characteristics, libido maintenance, skeletal muscle growth, male hypogonadism, delayed puberty, hormone replacement therapy
Admin: topical, implants, IM (PO not available in the US)
Testosterone adverse effects
- priapism
- premature epiphyseal closure
- gynecomastia
- profound secondary sex characteristics
- acne
- decreased HDL & increased triglycerides (leading to cardiac problems)
- bone demineralization
Testosterone nursing implications
- education on adverse effects
- admin instructions: topical should go on upper arms, upper thighs or axilla (axilla can increase concentrations because it doubles the skin contact for the med); for arms/legs be careful other people don’t touch & absorb med
- monitoring of anticipated outcomes
- maintenance of scheduled dose
- maintain physical activities (to decrease bone demineralization & keep bones strong)
- monitor labs: cholesterol, triglycerides & electrolytes
Anabolic-Androgenic steroids
No true medical use (athlete use to build up muscle tissue)
-benefits endurance athletes more than strength athletes (makes muscles work longer & harder)
Indications: increase protein synthesis within cells, buildup of muscle tissue, virilizing properties
Admin: IM
Anabolic-Androgenic steroids adverse effects
- increased LDL
- decreased HDL
- acne
- HTN
- liver damage
- left ventricular structural changes (because steroids increase workload of all muscles in body)
Spironolactone
Class: androgen antagonist
Indications: increased androgen; hormone associated conditions, BPH, prostate cancer, endometriosis, male-pattern baldness, acne, hirsutism
Off-Label uses: (to decrease levels of systemic testosterone) acne vulgarism, PCOS, MTF hormone therapy
Sprinolactone adverse effects
- electrolyte abnormalities (hyperkalemia)
- dehydration
- gynecomastia
- impotence
- orthostatic hypotension
Reasons for sexual dysfunction
- erectile dysfunction
- ejaculatory dysfunction
- failure of detumescence
Erectile dysfunction non-pharm therapies
- Herbal: improvement in blood flow, urethral irritation
- Hormonal: testosterone
- Injection/intraurethral pellet: causes vasodilation of penile arteries
- can include implanted devices in the penis (used for BPH too): opens up where the prostate narrows down on the urethra
Erectile dysfunction
- Causes: psychogenic, physiologic, pelvic trauma, medication induced
- Pharm treatment: phosphodiesterase inhibitors, hormone therapy, injection therapy, herbal therapy
- Non-pharm treatment: topical, mechanical
Sildenafil
Class: Phosphodiesterase inhibitors (PDE-5)
Indications: erectile dysfunction, pulmonary HTN (increases effects of nitric oxide & produces smooth muscle relaxation –> pulmonary veins & arteries dilate)
-NOT for arousal/stimulation/libido
Admin: oral; onset & duration is variable (depends on patient’s preference/goals)
Sildenafil adverse effects
- headache
- hypotension/syncope
- priapism
Sildenafil nursing implications
- educate regarding the use of nitrates (also affect nitric oxide. If used together, can have profound vasodilation)
- BP monitoring with syncope/pre-syncope
- seek medical attention for priapism
- encourage discussions & questions
Failure of detumescence - ischemic priapism
Causes:
-impaired venous flow: blood flow to the penis is normal, but the blood isn’t allows out of the penis through the venus system (so much pressure on the veins they’re collapsed & not letting blood out of oxygenated blood back in)
-penile trauma
-systemic vascular disease
-neuroregulation
-drug effects
Treatment:
-direct admin of arterial constrictors into the penis (if this doesn’t work, then surgery to relieve pressure on venous system & allow blood flow to normalize)
-immediate medical/surgical emergency (tissue necrosis can occur)
Failure of detumescence - nonischemic priapism
Causes:
-increased arterial flow: increased blood flow to penis, but it’s not allowed out through the venus system
-AV fistula
-neuroregulation
Treatment: not a medical emergency, but need to treat the underlying problem
Types of ejaculatory dysfunction
Premature: sooner than desired
Inhibited: prolonged
Retrograde: backward flow of semen into the bladder instead of through the urethra
-not harmful, but has associated infertility
Ejaculatory dysfunction treatment
- psychogenic
- pelvic floor exercises
- pharmacologic
- androgen deficiency
Benign prostatic hypertrophy
- hyperplasia of prostatic tissue
- symptoms: urinary hesitancy, frequency & dribbling, nocturne, urinary bladder fullness
Tamsulosin
Class: alpha 1 adrenergic blocker
MOA: blocks receptor sites at the neck of the bladder (and some in the kidney)
Indications: BPH
Off-Label use: passage of kidney stones < 5mm
Admin: oral
Tamsulosin adverse effects
- hypotension
- orthostasis
- dizziness
Tamsulosin nursing implications
- symptoms of orthostatic hypotension
- do NOT crush
- education on how they’ll know it’s working correctly (ie. relief of their specific BPH symptoms)
