Semen issues


Hello, doctor.
Last week, after urinating, I experienced some itching and pain in my urethra.
I went to the pharmacy and got medication for urethritis, which is the kind that turns urine orange.
A few days later, I visited a urologist for a check-up, and after a urinalysis, the doctor said there was no inflammation.
However, when I masturbated at night, my semen appeared yellow.
I haven't masturbated for about a week.
Could this be due to abstinence, or is it possible that there was inflammation that just didn't show up in the tests? Or could it be that the medication for urethritis is causing the discoloration, similar to how it affected my urine? Thank you for your response, doctor.

Hello: If there has been sexual intercourse (not masturbation), you should visit a urology department for an examination and inform the physician about when the sexual activity occurred.
The color of semen can vary at different times, but if there are symptoms in the urethra, an examination is necessary.
If there has been no sexual activity, you can observe the situation.
Wishing you good health.

Understanding changes in semen color can be a source of concern for many individuals, and it’s important to approach this topic with a clear understanding of potential causes and implications. Based on your description, there are several factors that could contribute to the yellow coloration of your semen, and I will address these below.

Firstly, it is essential to recognize that the color of semen can vary due to several reasons, including diet, hydration levels, and health conditions. A yellowish tint in semen is not uncommon and can sometimes be attributed to dietary factors, such as the consumption of certain foods (like asparagus or foods high in beta-carotene) or supplements. However, in your case, the recent use of medication for urinary tract infection (UTI) could also be a significant factor. Many medications, particularly those containing phenazopyridine (often used to relieve urinary pain), can cause urine and potentially semen to take on a bright orange or yellow hue. This could explain the color change you observed.

Regarding your experience of urethral itching and pain, it’s good to hear that your urine tests came back negative for inflammation. This suggests that there may not have been a significant infection at the time of your visit to the urologist. However, it’s worth noting that some infections can be transient or may not always show up in standard urine tests. If you continue to experience discomfort or if the color of your semen does not return to normal, it would be prudent to follow up with your healthcare provider for further evaluation.

The question of whether abstaining from ejaculation could lead to changes in semen color is also relevant. While abstaining from ejaculation for a week is unlikely to cause a significant change in color, it can lead to a concentration of sperm and seminal fluid, which might alter the appearance slightly. However, this is typically not a cause for concern unless accompanied by other symptoms.

In summary, the yellow coloration of your semen could be attributed to several factors, including the medication you took for urinary discomfort, dietary influences, or simply a natural variation. If the color persists or if you have any ongoing symptoms, it would be advisable to consult with your healthcare provider for a thorough examination and possibly further testing. They can provide personalized advice and reassurance based on your specific health situation.

In conclusion, while changes in semen color can be alarming, they are often benign and can be explained by various factors. Maintaining open communication with your healthcare provider is crucial for addressing any concerns and ensuring your overall health and well-being.
