Urology: Concerns About Penis and Testicle Changes

Some questions?

I would like to ask the doctor about the redness on the tip and upper part of my glans, which appears red, while the sides are somewhat purplish-red, and the surrounding area, specifically the edge of the corona, is deep purple.
This has been the case for a long time.
Is this normal? Additionally, I have another question regarding my testicles.
When I palpate them, sometimes they feel fine, but at other times they feel less full or seem to have shrunk.
Is it normal for testicles to change in this way? Thank you.

1.
The difference in the color of the glans is likely due to the amount of blood filling it.
If there are no other discomforts or issues with erection, it should not be a concern.
2.
As for the scrotum varying in size, this is a natural physiological phenomenon aimed at regulating the temperature within the scrotum to facilitate sperm production and survival, so there is no need for excessive worry.

When it comes to concerns about changes in the penis and testicles, it's essential to approach the situation with a clear understanding of normal anatomy and physiology, as well as potential medical issues that could arise.
Firstly, regarding the coloration of the glans (the head of the penis), it is not uncommon for the glans to exhibit variations in color. The glans can appear redder due to increased blood flow, irritation, or inflammation. The presence of a deep purple color around the corona (the ridge of the glans) may also be normal for some individuals, particularly if it has been consistent over time and is not accompanied by other symptoms such as pain, itching, or discharge. However, if there are any changes in color that are sudden or associated with discomfort, it would be prudent to consult a healthcare provider for a thorough examination.

As for the testicles, it is normal for them to vary in size and firmness throughout the day. Factors such as temperature, arousal, and even time of day can influence the size and firmness of the testicles. For instance, during warmer temperatures, the scrotum relaxes, and the testicles may hang lower and feel less firm. Conversely, in cooler conditions, the scrotum contracts, and the testicles may feel tighter and appear smaller.
However, if you notice a significant change in the size of your testicles, or if they feel consistently less firm or smaller over time, it could indicate a potential issue that warrants further investigation. Conditions such as testicular atrophy, varicocele (enlargement of veins within the scrotum), or hormonal imbalances can affect testicular size and firmness.
In summary, while some variations in color and size of the penis and testicles can be normal, any persistent changes, especially those accompanied by discomfort or other symptoms, should be evaluated by a healthcare professional. Regular check-ups and open communication with your doctor about any concerns can help ensure that any potential issues are addressed promptly and effectively.
If you have had any recent sexual activity or are concerned about sexually transmitted infections (STIs), it is also advisable to discuss this with your healthcare provider, as certain infections can manifest with changes in genital appearance or discomfort. Comprehensive STI screening may be warranted based on your sexual history and any symptoms you may be experiencing.
In conclusion, while some changes in the penis and testicles can be normal, it is always best to err on the side of caution and seek medical advice if you have any concerns. Your health and peace of mind are paramount, and a healthcare provider can offer the best guidance tailored to your specific situation.
