It also appears radiation from cancer therapy, in general, can have a negative effect on penis size.
This is due to the fact that radiation poisons cells, and it can be rather indiscriminate.
Once cells, like the smooth muscle cells of the penis, are damaged through radiation cancer treatment, it can be hard for them to recover.
3. Weight gain
Weight shrinks your penis in a few ways.
Larger Stomach - The larger your stomach is, the smaller your penis looks. This is not actual shrinkage, but it can cause a lot of mental anguish for guys.
Poor Erection Strength -Having a lot of fat around your abdomen and pelvis reduces blood flow transiently to your penis, which makes getting erections more difficult.
For a lot of men, losing weight will help alleviate symptoms of ED immediately by reducing the pressure of fat on the blood vessels that supply your penis.
Increased Levels of Estrogen -The last way weight gain affects penis size is that fat produces estrogen.
When estrogen is dominant, it suppresses androgens, which suppresses the regeneration and growth of smooth muscle cells in the penis.
This type of penis shrinkage, related to obesity, is more permanent.
Losing weight in most cases will resolve obesity-related penis shrinkage and prevent the long-term, permanent type of penile atrophy related to being overweight.
A few things to try:
exercise more often
reduce sugar intake
avoid processed foods
get better sleep
These changes will improve your overall health and give you better blood flow and increased stamina, allowing you to last longer in bed.
This disease not only makes the penis curve and sex difficult, but it also effectively reduces the size of the penis because of the bend or curve caused by the scar tissue.
The treatments do a good job of helping you resume a normal sex life, but Peyronie's isn't "curable" in a traditional sense.
Once it happens, your penis will be curved to a degree, and you will lose some length on your penis permanently.
5. Medications
Certain medications reduce blood flow or disrupt the hormones responsible for male sex drive and erections.
Others make it difficult to achieve an erection for other reasons, but with medications, the disruption is only temporary (in most cases).
If your doctor starts you on a drug that appears to be causing ED or penis shrinkage, speak with them and see if there's another option.
6. Smoking
Smoking is terrible for you across all systems and measurements of health, making your heart work harder, and not in a good way.
Smoking accelerates atherosclerosis by increasing the rate of plaque build-up in your arteries.
It can reduce blood flow to the penis and makes it smaller while erect. In fact, studies show that smoking causes weaker erection due to the reduced blood flow.
