Reproductive system

Male reproductive system

Anatomy and physiology

• Primary Structures: Testes, epididymis, vas deferens, seminal vesicles, prostate gland, urethra, and penis
• Function: Produces sperm and male sex hormones (testosterone)
• Hormonal Regulation:
  • Hypothalamus → Gonadotropin-releasing hormone (GnRH)
  • Pituitary → Luteinizing hormone (LH) & Follicle-stimulating hormone (FSH)
    • LH stimulates testosterone production in testes.
    • FSH supports spermatogenesis

Definitions

Testosterone

Steroid hormone that stimulates development of male secondary sexual characteristics, produced mainly in the testes, but also in the ovaries and adrenal cortex.

Gonadotropine- releasing hormone

Hormone produced in the hypothalamus that stimulates the pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which in turn regulate the function of the gonads (testes and ovaries)

Luteinizing hormone

Hormone secreted by the anterior pituitary gland that stimulates ovulation in females and the synthesis of androgen in males

Follicle - stimulating hormone

Stimulates egg production in females, regulates menstrual cycle, supports sperm production in males

Common male reproductive disorders

Benign prostatic hyperplasia (BPH)

• Non-cancerous enlargement of the prostate
• Symptoms: Urinary frequency, nocturia, weak stream, incomplete bladder emptying
• Treatment: Medications (alpha-blockers), surgery if severe

Prostatitis

• Inflammation of the prostate, often bacterial
• Symptoms: Painful urination, pelvic pain, flu-like symptoms
• Treatment: Antibiotics, anti-inflammatories

Prostate cancer

• Most common cancer in men
• Symptoms: Often asymptomatic early, later includes urinary dysfunction and bone pain (metastasis)
• Diagnosed with PSA levels, biopsy
• Treatment: Surgery, radiation, hormone therapy

Erectile dysfunction

• Inability to achieve/maintain an erection
• Causes: Vascular disease, diabetes, psychological factors
• Treatment: Medications, lifestyle modifications

Testicular cancer

• Most common in men 15-35 years
• Symptoms: Painless testicular lump, swelling
• Treatment: Surgery (orchiectomy), chemotherapy, radiation

Female reproductive system

Anatomy and physiology

• Primary Structures: Ovaries, fallopian tubes, uterus, cervix, vagina, external genitalia
• Function: Produces eggs, sex hormones (estrogen, progesterone), supports fetal development during pregnancy
• Hormonal Regulation:
  • Hypothalamus → GnRH
  • Pituitary → LH & FSH

Definitions

Estrogen

Any of a group of steroid hormones which promote the development and maintenance of female characteristics of the body.

Progesterone

Steroid hormone released by the corpus luteum that stimulates the uterus to prepare for pregnancy

Common female reproductive disorders

Polycystic ovarian syndrome (PCOS)

• Hormonal disorder causing irregular ovulation, excess androgens, and ovarian cysts
• Symptoms: Irregular periods, infertility, hirsutism, insulin resistance
• Treatment: Hormonal therapy, weight management, insulin sensitizers

Endometriosis

Pregnancy considerations for physical therapy

Physiological changes during pregnancy

Musculoskeletal changes

• Increased lumbar lordosis and anterior pelvic tilt →low back pain
• Increased ligamentous laxity due to Relaxin hormone → joint instability, risk of injury
• Widening of the pelvis → sacroiliac (SI) joint pain, pubic symphysis dysfunction
• Diastasis recti (separation of the rectus abdominis)

Definitions

Relaxin hormone

Hormone, primarily associated with pregnancy, that loosens ligaments and softens the cervix, preparing the body for childbirth

Cardiovascular changes

• Increased blood volume (40-50%) and heart rate
• Decreased blood pressure in the first and second trimesters (due to vasodilation)
• Risk of supine hypotensive syndrome (compression of the inferior vena cava)

Respiratory changes

• Increased oxygen consumption
• Decreased lung expansion due to elevated diaphragm → shortness of breath

Metabolic changes

• Increased caloric demands.
• Gestational diabetes risk due to insulin resistance.

Other changes

• Increased urinary frequency due to bladder compression
• Weight gain (25-35 lbs is normal range)
• Hormonal changes (progesterone, estrogen, relaxin) affect mood, joints, and metabolism

Safe exercise guidelines for pregnancy

• Mode: Walking, swimming, cycling, low-impact aerobics.
• Intensity: Moderate (should be able to talk while exercising)
• Duration: 150 minutes per week (30 min/day, most days)
• Avoid:
  • Supine exercises after 20 weeks (risk of supine hypotensive syndrome)
  • Overheating (hot yoga, saunas).
  • Valsalva maneuver (holding breath during exertion)
  • High-impact or contact sports

Contraindications to exercise during pregnancy:

• Absolute:
  • Incompetent cervix
  • Placenta previa (after 26 weeks)
  • Preeclampsia
  • Multiple gestation with risk of preterm labor
  • Ruptured membranes
  • Persistent vaginal bleeding
  • Preterm labor
• Relative:
  • Severe anemia
  • Unevaluated maternal cardiac disease
  • Chronic bronchitis
  • Poorly controlled diabetes or hypertension

Postpartum considerations

• Pelvic floor dysfunction
  • Interventions: Kegels, biofeedback, bladder retraining
• Postural syndromes
  • Due to breastfeeding, baby-carrying
  • Interventions: strengthening of upper back, postural correction, stretching
• Return to exercise
  • Clearance from physician (typically 6 weeks post-vaginal, 8+ weeks post-C-section)
  • Progressive return to impact activities

Incontinence

Types of urinary incontinence and treatment

Urinary incontinence is the involuntary loss of urine due to dysfunction in the bladder, urethra, or pelvic floor muscles. There are several types, each with different causes and treatments.

Stress incontinence

Cause:

• Weak pelvic floor muscles or urethral sphincter dysfunction
• Common in postpartum women, postmenopausal women, and after prostate surgery in men
• Triggered by increased intra-abdominal pressure (e.g., coughing, sneezing, laughing, jumping)

Treatment:

• Pelvic floor muscle training (Kegels) to strengthen muscles
• Bladder training to improve control
• Biofeedback & electrical stimulation for muscle activation
• Pessary or urethral inserts (in some cases)
• Surgical options (e.g., sling procedures) for severe cases

Urge incontinence

Cause:

• Detrusor muscle overactivity leads to sudden, strong urges to urinate
• Can be related to neurological conditions (e.g., stroke, Parkinson’s, MS), infections, or idiopathic causes

Treatment:

• Bladder retraining (scheduled voiding, delaying urination)
• Pelvic floor exercises to control urgency
• Behavioral modifications (reducing caffeine, alcohol, and bladder irritants)
• Medications (anticholinergics, beta-3 agonists) to relax the bladder
• Neuromodulation (e.g., tibial nerve stimulation) in severe cases

Overflow incontinence

Cause:

• Incomplete bladder emptying due to obstruction (e.g., enlarged prostate, pelvic organ prolapse) or weak detrusor muscle (e.g., diabetes, spinal cord injury, multiple sclerosis)
• Symptoms include dribbling, weak stream, and feeling of incomplete emptying

Treatment:

• Double voiding technique (waiting and trying to urinate again)
• Timed voiding to prevent overflow
• Pelvic floor strengthening if related to muscle dysfunction
• Catheterization (intermittent or long-term) for severe cases
• Surgical intervention if caused by obstruction (e.g., prostate surgery)

Functional incontinence

Cause:

• Physical or cognitive impairments (e.g., stroke, dementia, arthritis, Parkinson’s) prevent timely access to the bathroom
• No direct bladder dysfunction, but mobility limitations or mental impairments lead to accidents

Treatment:

• Environmental modifications (accessible bathrooms, commodes, grab bars)
• Scheduled toileting based on routine
• Mobility training & assistive devices
• Caregiver education for dementia-related cases

Renal disorders

Common renal disorders

The kidneys play a vital role in filtering waste, regulating electrolytes, and maintaining fluid balance. Dysfunction can lead to serious systemic issues, including metabolic imbalances and cardiovascular complications

Acute kidney injury (AKI)

Definition: Sudden loss of kidney function due to ischemia, toxins, or trauma. It is often reversible if treated early

Causes:

• Pre-renal: Hypovolemia, shock, heart failure.
• Intra-renal: Acute tubular necrosis, nephrotoxic drugs, infections
• Post-renal: Obstruction (kidney stones, tumors, BPH)

Signs and symptoms:

• Oliguria (low urine output), fluid retention, electrolyte imbalances (increased potassium, increased BUN/Creatinine)

PT considerations:

• Monitor for fatigue, altered mental status, and electrolyte imbalances
• Avoid overexertion due to risk of hypotension and electrolyte shifts

Chronic kidney disease (CKD)

Definition: Progressive decline in kidney function, leading to end-stage renal disease (ESRD) if untreated

Causes:

• Diabetes (leading cause), hypertension, glomerulonephritis, polycystic kidney disease

Stages (GFR-based):

• Stage 1-2: Mild kidney damage, no major symptoms.
• Stage 3: Moderate impairment, possible anemia, bone mineral disorders
• Stage 4: Severe dysfunction, preparing for dialysis
• Stage 5 (End Stage Renal Disease): Requires dialysis or kidney transplant

Signs and symptoms:

• Fatigue, muscle cramps, edema, anemia, metabolic acidosis, hypertension, itching
• Uremia (buildup of waste in blood) → nausea, confusion, neuropathy

PT considerations:

• Monitor for fatigue, blood pressure changes, and electrolyte imbalances
• Encourage low-to-moderate intensity exercise to improve functional capacity
• Avoid excessive fluid loss (dehydration can worsen kidney function)
• Be aware of bone mineral disease & risk of fractures

Nephrotic syndrome

Definition: A kidney disorder causing severe protein loss in urine due to damage to glomeruli

Signs and symptoms:

• Severe edema (especially in the legs), proteinuria (>3.5g/day),hypoalbuminemia, hyperlipidemia.
• Increased risk of thrombosis and infections

PT considerations:

• Monitor for edema-related mobility restrictions
• Be cautious of increased clotting risk during exercise

Hemodialysis (HD) considerations

Hemodialysis is used in ESRD to filter blood through a machine when the kidneys can no longer perform their function. It is typically done 3-4 times per week for 3-5 hours per session

Common complications:

• Hypotension during or after dialysis (due to rapid fluid removal)
• Fatigue, dizziness, cramping (electrolyte shifts)
• Access site issues (fistula/graft infections, thrombosis)

PT considerations:

• Avoid exercise immediately before or after dialysis due to fatigue and hypotension risk
• Monitor blood pressure carefully – hypotension is common post-dialysis
• Exercise should be performed on non-dialysis days or at least 4+ hours after treatment
• Do not take blood pressure on the arm with an AV fistula/graft to prevent complications
• Encourage low-impact aerobic and resistance exercises to improve endurance and prevent muscle wasting
