Dr. Li Xinyi reply Urology


After an erection, the foreskin and the urethral opening can become completely red: It's important to pay attention to lubrication during masturbation (to avoid injuries) and cleanliness (to prevent wound infections or urinary tract infections).
If excessive force is applied, the tissue will naturally become red, swollen, and inflamed.
Frequent sexual activity may indicate a loss of balance in life, which is overall not good.
You are still young, and your puberty is not over; both your body and mind are healthy.
Transitioning into adulthood should be done gracefully.
If you notice that one testicle is larger than the other and are concerned, it is advisable to see a urologist for an examination and discuss it with the doctor.

Understanding discrepancies in testicular size and related urological issues can be quite complex, and it's important to approach this topic with a clear understanding of normal anatomy and potential medical concerns.
Firstly, it is not uncommon for men to notice a difference in the size of their testicles. In fact, slight asymmetry is normal, with one testicle often hanging lower than the other. However, if you observe a significant difference in size, it could be indicative of an underlying condition that may require medical evaluation.

One potential cause of a noticeable size discrepancy is a condition known as testicular atrophy, which can occur due to various factors including hormonal imbalances, trauma, or infections. Conditions such as varicocele, which is an enlargement of the veins within the scrotum, can also lead to changes in testicular size and may affect fertility. Additionally, testicular torsion, which is a medical emergency, can lead to severe pain and swelling, and if not treated promptly, can result in loss of the affected testicle.

Regarding the symptoms you mentioned, such as redness of the glans (the tip of the penis) and the foreskin after masturbation, this could be a sign of irritation or inflammation. Common causes for this include:
1. Irritation or Allergic Reaction: This can occur due to friction during masturbation or from soaps, lotions, or other products that come into contact with the genital area.

2. Infection: Conditions such as balanitis (inflammation of the glans) or posthitis (inflammation of the foreskin) can cause redness and swelling. These infections can be caused by bacteria, yeast, or sexually transmitted infections (STIs).

3. Dermatological Conditions: Skin conditions such as eczema or psoriasis can also affect the genital area, leading to redness and irritation.

4. Phimosis: If the foreskin is too tight and cannot be easily retracted, it can lead to irritation and inflammation, especially after sexual activity.

It is crucial to monitor these symptoms closely. If the redness persists, is accompanied by pain, swelling, discharge, or any other concerning symptoms, it is advisable to seek medical attention. A healthcare provider can perform a physical examination and may recommend tests to determine the underlying cause of your symptoms.

In summary, while slight differences in testicular size can be normal, significant discrepancies warrant further investigation. Additionally, redness and irritation following masturbation could indicate irritation or infection, which should be evaluated by a healthcare professional. Early diagnosis and treatment are key to managing any potential issues effectively. Always prioritize your health and do not hesitate to consult a urologist or your primary care physician for personalized advice and treatment options.
