Penile Changes: Is Urine Affecting Your Corpora Cavernosa?

Excessive self-defense leading to damage of the corpus cavernosum?

Hello doctor, I would like to ask about my penis.
It is usually quite short, but it becomes slightly larger when I urinate, and then it shrinks back afterward.
Is it possible that urine is entering the erectile tissue? Thank you for your response!

Gu Chen, 50~59 year old female. Ask Date: 2023/09/01

Understanding the changes in penile size and function can be a complex topic, especially when considering the physiological mechanisms involved. The corpora cavernosa, which are two columns of erectile tissue found in the penis, play a crucial role in achieving and maintaining an erection. When you urinate, the body undergoes various changes that can temporarily affect the size and firmness of the penis.

Firstly, it's important to clarify that the changes you observe—where your penis appears to enlarge slightly during urination—are likely due to increased blood flow to the area. When you are in a relaxed state, the blood vessels in the penis are not as engorged, which can make it appear smaller. However, during urination, there may be a slight increase in blood flow due to the body's response to the act of urination, which can cause the penis to appear larger temporarily.

The notion that urine could somehow "escape" into the corpora cavernosa is a misunderstanding of how the urinary and reproductive systems function. The urethra, which is the tube that carries urine from the bladder to the outside of the body, runs through the penis but is separate from the corpora cavernosa. Therefore, urine does not enter the corpora cavernosa. Instead, the engorgement of the penis during urination is primarily a result of blood flow dynamics rather than any fluid exchange.

If you notice significant changes in size or function that are concerning, it may be worth consulting a healthcare professional. Conditions such as Peyronie's disease, erectile dysfunction, or other vascular issues can affect penile function and size. Additionally, if you experience pain, discomfort, or any other unusual symptoms during urination or sexual activity, it is advisable to seek medical advice.

In terms of nutrition and overall health, maintaining good vascular health is essential for proper erectile function. This includes a balanced diet rich in fruits, vegetables, whole grains, and lean proteins, as well as regular exercise to promote cardiovascular health. Staying hydrated is also important for overall bodily function, including urinary health.

In conclusion, the changes you are experiencing during urination are likely due to increased blood flow rather than any direct interaction between urine and the corpora cavernosa. If you have ongoing concerns about your penile health or function, it is best to consult with a urologist or healthcare provider who can provide personalized advice and treatment options.
