Concerns About Prolonged Erections After Taking Viagra: What You Need to Know - Urology

Corpus cavernosum..?


Thank you, doctor.
I am the one who asked about the corpus cavernosum last time.
I know that men often experience erections during the night, but they don't last for a long time.
I am concerned that taking Viagra that night may have caused an erection that lasted too long and resulted in injury.
This was six months ago, and I have not taken it again.
I also experience morning erections.
Does this indicate that my penis has not been injured?

Just kidding! Don't treat the medication as an aphrodisiac anymore! It's all good! Stop being paranoid! Let me recommend a few books that are beneficial for the corpus cavernosum: "About Sex" and "The Love of the Little Brother."

More Info


Concerns about prolonged erections, particularly after taking medications like Viagra (sildenafil), are valid and warrant careful consideration. Viagra is a phosphodiesterase type 5 (PDE5) inhibitor that enhances blood flow to the penis, facilitating erections in response to sexual stimulation. However, one of the potential side effects of this medication is priapism, which is defined as an erection lasting longer than four hours. Priapism is a medical emergency that can lead to permanent damage to the penile tissue if not treated promptly.

In your case, you mentioned experiencing prolonged erections after taking Viagra, but it has been six months since you last used the medication. You also noted that you still experience morning erections, which is a normal physiological response. Morning erections, or nocturnal penile tumescence, are common in healthy males and indicate that the erectile tissues are functioning properly. The fact that you are still able to achieve erections suggests that your penis has likely not sustained any significant injury from the previous episode of prolonged erection.

However, it is essential to understand a few key points regarding the use of Viagra and the concerns surrounding prolonged erections:
1. Priapism Risk: While Viagra is generally safe for most men, the risk of priapism increases in certain populations, such as those with sickle cell anemia, leukemia, or multiple myeloma. If you have any underlying health conditions, it is crucial to discuss these with your healthcare provider before using erectile dysfunction medications.

2. Symptoms of Priapism: If you ever experience an erection lasting longer than four hours, it is vital to seek immediate medical attention. Symptoms of priapism may include pain in the penis, a rigid erection that does not subside, and swelling. Prompt treatment is necessary to prevent long-term complications.

3. Post-Erection Sensations: After experiencing a prolonged erection, some men may feel soreness or discomfort in the penile area. This is typically temporary and should resolve on its own. However, if you experience persistent pain, changes in sensation, or any other unusual symptoms, it is advisable to consult a healthcare professional.

4. Psychological Factors: Anxiety about the effects of medications like Viagra can sometimes lead to heightened awareness of bodily sensations, including erections. If you find yourself overly concerned about your sexual health or the effects of medications, consider discussing these feelings with a mental health professional or a urologist who specializes in sexual health.

5. Future Use of Viagra: If you are considering using Viagra again in the future, it is essential to follow the prescribed dosage and guidelines provided by your healthcare provider. Avoid taking more than the recommended dose, and do not combine it with other medications without consulting your doctor.

In summary, while your current ability to achieve erections suggests that your penis has likely not been harmed, it is essential to remain vigilant about any unusual symptoms. If you have ongoing concerns or experience any new symptoms, do not hesitate to reach out to a healthcare professional for further evaluation and guidance. Your sexual health is an important aspect of your overall well-being, and addressing any concerns promptly can help ensure that you maintain a healthy sexual function.
