How does the penis change as you get older?

The male penis has certain changes over time due to a decrease in the amount of testosterone hormone and the aging of parts related to the genital system.

Male genitalia also go through a series of changes throughout life from birth, through puberty, and into old age. During each period, the changes in the penis are controlled mainly by testosterone levels.
Between the ages of 9 and 15, the pituitary gland secretes hormones that stimulate the body to produce testosterone. Puberty begins and a series of significant changes occur. Pubic hair begins to grow, testes may shrink, scrotum may become saggy, penis size may shorten, etc. Testosterone levels in men peak during adolescence until early 20s. . Between the ages of 20 and 40, the amount of testosterone in the body may decrease slightly, but the reduction is very small.
After the age of 40, total testosterone hormone levels only decrease by a negligible amount. However, during this stage the male body begins to make a protein called sex hormone binding globulin (SHBG). SHBG binds to testosterone in the blood, resulting in a decrease in the amount of testosterone available for use.

When testosterone levels decrease, men will notice the following changes in their penis:
Pubic hair Similar to hair and other body hair, under the influence of time, pubic hair also becomes thin and may turn gray-white.
Penis Size As men get older, the penis size may not be the same as before. In fact, the penis size may be shorter. Furthermore, for overweight men, a lot of fat accumulation in the pubic area (just above the penis), can cause this area to sag and make the penis appear smaller.
Penis shape For some men, the penis may become somewhat curved after a period of time, affecting length, girth and function. This phenomenon, known as Peyronie's disease, is usually caused by physical trauma, stemming from the constant bending of the shaft of the penis during sex. When it returns to its normal state, scar tissue will form along the hard shell surrounding the corpus cavernosum. The scar tissue can enlarge, causing the penis to curve during an erection. This condition can be treated with surgery or medication. Testicles The testicles are located inside the scrotum of a man's penis and are mainly responsible for the production of sperm. When testosterone levels decrease (due to aging or other causes), sperm production slows and testicles shrink. In the case of hormone replacement therapy, the patient's pituitary gland will stop. Stop sending signals to the testicles to make testosterone, which causes the testicles to shrink more.
The scrotum contains the testicles The job of the scrotum is to contain and regulate the temperature of the testicles. The scrotum is lined with smooth muscle, which can contract to bring the testicle closer to the body to keep warm, or expand to "float" and cool the testicle. As men age, the muscles become aging and no longer work as well, causing the function of the scrotum to also be affected and become slower. In addition, this also adversely affects the skin, reducing its natural elasticity, making sagging worse and worse.

For men over the age of 40, hydrocele can also be the cause of your scrotum sag. This condition occurs when fluid builds up around one or both testicles. The reason is that the body has reached the aging stage and has produced too much fluid or maybe the function of excreting water is not good. This is usually painless, but can lead to swelling and discomfort. In this case, the patient should see a doctor for appropriate treatment.
Penile function As men age, the nerves in the penis become less sensitive to stimulation signals. The consequences can lead to some problems with the ability to get an erection and reach orgasm.
When testosterone levels drop, men are more likely to experience erectile dysfunction. Accordingly, the male penis is incapacitated or has a lot of difficulty in getting an erection during sex despite still having sexual desire. This seriously affects the sex life of men.
The main cause of this condition is the aging of the male body, which leads to a decrease in blood circulation and a decrease in the ability to retain blood in the penis to maintain an erection. As a result, the patient can achieve an erection but cannot maintain it long enough to have sex or climax.

Many older couples or even relatively young couples already face the daily stresses related to sex. Therefore, to prevent the effects of aging, men need to be aware of the importance of the following:
Maintain a moderate weight. Lose weight if you are obese Eat a healthy diet, full of nutrients Avoid sitting a lot (sitting for a long time puts a lot of pressure on the prostate gland) Exercise regularly, especially exercise to maintain the tone of your body. pelvic floor muscles (like Kegel exercises). Jogging or brisk walking are also good exercises for men's health. Supplement with the necessary amount of zinc and selenium. Limit alcohol intake. Alcohol stimulates the conversion of testosterone to estrogen (which lowers testosterone) and increases the risk of genital inflammation. Avoid smoking. Toxic substances in cigarette smoke affect heart health and blood circulation

Get enough sleep every day Treat related diseases, use drugs as prescribed by the doctor, avoid arbitrarily taking drugs; Limit stress, improve psychological well-being, always keep an optimistic, happy spirit Build an intimate emotional relationship with your partner and have consensus, try both of them to support the man against problems with sex in old age Examination, diagnosis and treatment of male diseases, if present Genitourinary changes and a decrease in male sex drive are an inevitable part of the process. aging process as men age. However, if these changes greatly affect the quality of life as well as the relationship with sexual partners, men should go to a medical facility for examination and treatment.
