Aging Differences Between Men and Women

When it comes to aging, women tend to live longer but does that mean they age better? Or do men maintain certain physical advantages as they grow older? The truth is, aging is a complex and deeply individual process, influenced by genetics, hormones, lifestyle, and even how we interact with healthcare.

While many factors contribute to how we age, understanding the biological and social differences between cisgender men and women can offer valuable insights into how to protect your health and well-being as the years go by.

Longevity: Women Live Longer, On Average

Globally, women consistently outlive men. In the United States, the average life expectancy is:

• 74.8 years for men

• 80.2 years for women

This difference is often attributed to a combination of behavior, biology, and healthcare habits. Men tend to engage in riskier behavior, have more dangerous jobs, and are less likely to seek medical care proactively.

Why Appearance May Change Differently

It’s a common stereotype that men "age better," especially when it comes to appearance but the science tells a more nuanced story.

• Men lose collagen a key protein in skin gradually over time.

• Women, on the other hand, retain more collagen until menopause, when collagen levels drop sharply.

This explains why men may appear to age more slowly at first, while women may experience a more dramatic shift in their 40s and 50s.

Hormones: A Driving Force Behind Aging Differences

Sex hormones significantly influence how we age. Though all people produce androgens (like testosterone) and estrogens, the balance and rate of decline differ between men and women.

For men:

• Testosterone supports muscle mass, bone strength, and overall vitality.

• As levels drop, men often experience weight gain, fatigue, depression, and a higher risk for chronic illnesses like diabetes and heart disease.

For women:

• Estrogen plays a role in bone health, cognitive function, and metabolism.

• During menopause, estrogen levels plummet leading to symptoms like hot flashes, mood changes, bone loss, and changes in sexual function.

The key difference? Men experience a gradual hormonal decline, while women often undergo a sudden shift during menopause, which can create a steeper aging curve in midlife.

Sexual Health and Aging

Sexual function naturally changes with age, and hormones play a large part:

• Men typically begin experiencing reduced testosterone levels in their late 20s, with noticeable changes in libido or performance often appearing by their 50s.

• Women may see increased sexual desire in their late 20s to early 40s, followed by a decline during and after perimenopause due to lower estrogen levels.

Symptoms such as erectile dysfunction, vaginal dryness, and reduced orgasmic response become more common in the 50s and 60s for both sexes, but many adults remain sexually active and engaged well into older age.

In one study, 40% of women over 60 reported low libido but still considered sex an important part of life.

Brain Aging: A Subtle but Crucial Difference

The brain also ages differently in men and women:

• Studies show that, on average, male brains appear three years older than female brains of the same chronological age.

• Cognitive decline in men is more often linked to physical health factors like diabetes or stroke.

• For women, factors like social isolation or being dependent on others may contribute more significantly to cognitive decline.

That said, individual brain aging varies widely, and maintaining social connections, physical activity, and good nutrition supports cognitive function regardless of sex.

Healthcare Habits: Women Take the Lead

Women are more likely to seek preventive care, attend regular checkups, and follow medical advice. These habits may contribute to their longer life expectancy and better health outcomes in later life.

Men, by contrast, often avoid routine care potentially delaying the diagnosis and treatment of chronic illnesses. This difference in healthcare utilization plays a critical role in long-term aging outcomes.

Lifestyle and Environmental Factors

While sex and hormones play a major role, many other factors influence how well we age:

• Genetics: Inherited traits influence longevity and disease risk.

• Nutrition: Diets rich in whole foods, healthy fats, and fiber support long-term health.

• Physical activity: Regular movement helps maintain muscle, bone, and brain health.

• Sleep: Quality sleep helps regulate hormones, metabolism, and mood.

• Environment: Exposure to pollution, stress, and socioeconomic factors also play a role.

While genetics are out of your control, lifestyle choices are not. Small, consistent habits like daily walks, limiting alcohol, or adding more vegetables to your meals can have a profound impact on how you age.

What About Centenarians?

People who live to be 100 or more known as centenarians offer insight into aging well. Women are more likely to reach this milestone, but men who do tend to be healthier overall.

Among centenarians:

• 43% of women and 24% of men survived at least one serious illness before age 80.

• 32% of men and 15% of women reached age 100 without any major illness ("escapers").

• Men are more likely to age healthfully if they make it to 100, while women tend to be more resilient to chronic conditions over time.

The Bottom Line

While women live longer and often take better care of their health, they also face more abrupt changes in midlife due to hormonal shifts. Men may appear to age more gradually, but they’re more vulnerable to chronic conditions and cognitive decline earlier.

Ultimately, aging isn’t a competition it’s a process that can be influenced by your choices, environment, and access to care. Understanding these differences empowers both women and men to take proactive steps toward aging with strength and vitality.
