Penis size can change over time due to a variety of factors such as aging, hormonal changes, and certain medical conditions.

As men age, the levels of testosterone, the male sex hormone, decrease, which can cause a decline in penis size. This can lead to a decrease in the size of the erect penis and a decrease in the size of the flaccid penis.

Hormonal changes, such as those that occur during puberty, can also affect penis size. During puberty, the levels of testosterone increase, which can cause an increase in penis size.

Certain medical conditions, such as obesity and Peyronie’s disease (a condition in which scar tissue forms inside the penis), can also affect penis size. Obese men may have a smaller penis size, while men with Peyronie’s disease may have a curvature or shortening of the penis.

It’s important to note that penis size can also be affected by lifestyle factors such as smoking, alcohol, and drug use. These factors can damage the blood vessels in the penis and decrease the blood flow, which can affect the size of the erect penis.

It’s important to consult a healthcare professional if you are experiencing a significant change in penis size, as it could be a symptom of an underlying condition that requires medical attention. They will be able to assess your individual situation and provide guidance on any treatment options that may be available.
