WHAT IS THE LIFE CYCLE FOR MEN AND WOMEN?

The life cycle for men and women follows the same general biological stages, but the timing, physical changes, and health concerns can differ due to sex-specific biology and hormones.

Here’s a clear stage-by-stage breakdown:

1. Infancy (0–2 years)

• Both: Rapid growth, brain development, sensory exploration.
• Key needs: Breastfeeding or formula, vaccines, bonding, and protection.

2. Childhood (3–12 years)

• Both: Physical growth, motor skill development, learning language and social skills.
• Differences: Boys may develop slightly more muscle mass; girls often develop fine motor skills and language earlier.

3. Adolescence / Puberty

• Men:
• Starts ~11–15 years.
• Testosterone increases → deeper voice, muscle growth, facial hair, sperm production.
• Women:
• Starts ~9–14 years.
• Estrogen increases → breast development, menstruation, wider hips.

4. Early Adulthood (20s–30s)

• Both: Physical peak, fertility, career building, possible parenthood.
• Men: Testosterone at high levels; higher muscle mass and metabolism.
• Women: Regular menstrual cycles, peak fertility, pregnancy and childbirth possible.

5. Middle Adulthood (40s–50s)

• Men: Gradual testosterone decline, possible changes in muscle, mood, and sexual function.
• Women: Perimenopause and menopause (around 45–55 years), estrogen decline, end of fertility.
• Both: Increased risk for chronic diseases (hypertension, diabetes, heart disease).

6. Older Adulthood (60s and above)

• Both: Muscle mass and bone density decrease, slower healing, more fragile immune system.
• Men: Higher risk of prostate problems, heart disease.
• Women: Higher risk of osteoporosis, fractures, certain cancers.
• Both: Cognitive changes may occur, greater focus on healthy aging.

7. End-of-Life Stage

• Both: Frailty, possible need for full-time care, increased vulnerability to illness.
• Women: Often outlive men by several years on average.
