Normal aging changes in the scrotum and testicles
The perception that "balls drop with old age" is a common concern based on observable changes in the male anatomy. The testicles themselves do not technically "drop" from their position inside the scrotum. The scrotum, which holds the testicles, loses elasticity with age, leading to a lower-hanging appearance. This is a normal part of aging.
The science behind scrotal sagging
Several factors contribute to scrotal sagging in older men:
- Loss of collagen and elasticity: Like other skin, scrotal skin loses collagen and elastin over time, becoming thinner and stretchier. This is a primary cause of sagging.
- Weakened cremaster muscles: These muscles raise and lower the testicles for temperature regulation. With age, they weaken, leading to a lower position.
- Impact of gravity: Gravity's effect, combined with decreased skin elasticity and muscle tone, contributes to the lower-hanging appearance.
Potential medical causes and when to see a doctor
While sagging is normal with age, other conditions can affect the scrotum. Consult a doctor if you notice any of these symptoms along with changes in scrotal appearance:
- Varicocele: Enlarged veins in the scrotum can feel like a "bag of worms" and may cause the testicles to hang lower.
- Inguinal hernia: Tissue pushing through abdominal muscles can cause a bulge, pain, and swelling in the groin or scrotum.
- Testicular cancer: A lump, swelling, or enlargement of the testicle requires medical evaluation.
- Testicular atrophy: The actual shrinking of testicles can be caused by various factors and needs medical attention.
The relationship between aging, hormones, and testicular function
Testicular aging impacts reproductive and overall health, affecting hormone production and sperm quality.
Declining testosterone levels
As men age, testosterone levels gradually decline. This can cause symptoms like decreased libido, erectile dysfunction, loss of muscle mass, fatigue, and mood changes.
Effects on fertility and sperm quality
Sperm quality and DNA integrity decline with age, particularly after 40. This can increase the risk of miscarriage and genetic mutations.
Comparative table of normal vs. abnormal scrotal changes
Feature | Normal Age-Related Change | Potentially Abnormal Change (Requires Evaluation) |
---|---|---|
Scrotal Skin | Thinner, looser, and more wrinkled with visible sagging. | Swollen, discolored, or asymmetrical appearance. |
Testicle Position | Hanging lower due to weakened muscles and loss of skin elasticity. | One testicle consistently hangs much lower, especially with a mass or pain. |
Testicle Size | Gradual, moderate decrease in volume after age 60. | Sudden or significant shrinkage (testicular atrophy). |
Pain or Discomfort | Generally painless, though excessive sagging can cause mild discomfort. | Chronic pain, swelling, or a feeling of heaviness or aching. |
Other Symptoms | May be accompanied by signs of lower testosterone. | Associated symptoms like a mass, lump, or sudden severe pain. |
Lifestyle factors and management options
While aging is natural, healthy habits can support overall health and may help mitigate some symptoms. Lifestyle choices support skin health and hormonal balance but won't reverse aging's effects.
- Maintain skin health: Sun protection, hydration, and a healthy diet can support skin health.
- Exercise regularly: Physical activity helps maintain muscle tone, including cremaster and dartos muscles.
- Avoid smoking and limit alcohol: These can accelerate aging and negatively impact testicular health.
- Consider surgical options: Scrotoplasty can remove excess scrotal skin for those bothered by sagging.
When to seek professional advice
Understanding normal age-related changes is helpful, but be aware of signs of more serious issues. Any lump, swelling, significant pain, or change in testicle size or shape warrants a visit to a healthcare provider. A urologist can diagnose potential issues.

Conclusion
Scrotal sagging is a normal part of aging caused by loss of skin elasticity and muscle tone. While this is typical, be aware of other potential issues. Understanding these changes and seeking professional help for concerning symptoms is important for men's health as they age.
