The Biological Process of Aging in Men: A Comprehensive Overview
Aging is an inevitable biological process that occurs gradually over time. It represents a complex natural phenomenon characterized by the decline of both structure and function, adaptive abilities, and resistance. Biologically, aging can be viewed as an individual's development from fertilization to old age. Pathologically, it results from accumulated stress, wear and tear, damage and infection, weakened immune responses, nutritional deficiencies, metabolic disorders, as well as neglect and abuse. As a part of their physical identity, men's bodies also show signs of aging. What are these signs?
1. Changes in Appearance
Experts from Beijing Shuguang Hospital point out that men in their forties may notice a gradual loss of the reddish-purple color of the glans. This change primarily results from decreased blood circulation. Additionally, reduced androgen levels may lead to thinning pubic hair, reverting to a pre-adolescent state where hair is less prominent.
2. Size Reduction
It is common for men to gain weight as they age. In some cases, abdominal fat may obscure the penis. Both the length and girth of the penis can experience slight changes. For example, if a Western man had a penis measuring 15 centimeters when erect in his thirties, it may shrink to around 12 centimeters by his sixties or seventies.
In a study of 1,412 healthy young Chinese males, the average erect penis length was found to be approximately 12 centimeters, with a range from 9 to 16 centimeters. Additionally, a survey of 1,000 normal adult males reported an average length of 6.55 centimeters in a non-erect state, with the longest measuring 10.6 centimeters.
Considering these findings, there are variations in results that can be attributed to factors such as region and ethnicity. Moreover, the measurements can fluctuate based on individual conditions like stress, cold temperatures, or fatigue, which may cause temporary shrinkage. Thus, these figures should be seen as general references rather than definitive standards.
3. Increased Curvature
Men might experience increased curvature of the penis due to uneven scar tissue accumulation, a condition known as Peyronie's disease, which is more commonly seen in middle-aged men. This condition can lead to painful erections and difficulties during intercourse. Patients exhibiting symptoms should seek medical attention. Symptoms include:
- Presence of painless hard lumps on the penis
- Curvature, either upward or downward, during erections
- Shortening and deformation of the penis
- Discomfort or pain during erections
- Potential erectile dysfunction
4. Decreased Sensitivity
Studies indicate that as men age, the sensitivity of the penis may decline, potentially affecting erections and delaying climaxes. Although these changes are often unavoidable, they do not necessarily lead to a significant impact on sexual intercourse. The essence of a fulfilling sex life relies on the ability to satisfy one’s partner rather than focusing solely on certain anatomical features.
Strategies to Delay Aging Signs
Want to postpone the signs of aging in your most treasured asset? Just like maintaining overall health, practicing routine measures can make a difference. Experts from Beijing Shuguang Hospital recommend several simple massages to help keep the penis healthy and robust:
1. Lower Abdominal Friction
Before sleeping, place one hand just below your navel and the other on your waist. While pressing down on your waist, gently rub your lower abdomen from right to left until you feel warmth in the area.
2. Upper Thigh Massage
Before going to bed, use both hands to gently massage the upper thighs with your palms for 36 counts. Performing this massage weekly may boost libido and enhance energy levels.
3. Strengthening the Response
When you wake up in the morning and before urinating, apply gentle pressure to the lower third of the penis to encourage a near-erect state. Use your fingertips to sense the response while tightening the anal sphincter and pushing the penis upward. Repeat this for about a minute.
4. Massaging the Testicles
Warm your hands and grasp the testicles, alternating gentle rotations to the right (30 to 50 times) and then to the left (30 to 50 times), ensuring a mild sensation without discomfort. This method, known as "grasping the scrotum," may also involve gently applying pressure with one hand while the other massages.
It is important to note that sexual intercourse itself is one of the best exercises for maintaining penile health, so engaging in sexual activity at least once a week can be beneficial.
By implementing these practices, men may enhance their sexual health and quality of life as they navigate the changes associated with aging.
