Semen


Hello, Dr.
Hsu! I remember that the color of my semen used to be milky white (slightly yellow), but now it is yellow-green.
Is this normal? If it is not normal, what could be the causes or diseases associated with it? What uncomfortable symptoms might I experience?

Jan: The color of semen is generally normal if it ranges from clear to slightly white or slightly yellow.
The presence of red or foul-smelling semen may indicate a problem.
It is usually recommended to have a semen analysis to determine the underlying factors.
The most common causes include infections and inflammation.
If you have any further questions or need clarification, feel free to ask, and we can discuss and research it together.

More Info


When it comes to the color of semen, a shift from the typical whitish or slightly yellow hue to a yellow-green color can indeed raise some concerns. While variations in semen color can occur due to a variety of factors, a persistent change to yellow-green is often indicative of underlying issues that may require further investigation.


Normal Variations and Causes
Semen color can be influenced by several benign factors, including diet, hydration levels, and frequency of ejaculation. For instance, consuming certain foods like asparagus or taking supplements can alter the color of semen. Dehydration can also concentrate the semen, leading to a darker appearance. However, if the color change is significant and persistent, it may warrant a closer look.


Potential Medical Concerns
1. Infection: One of the most common causes of yellow-green semen is an infection, particularly in the reproductive or urinary tract. Conditions such as prostatitis (inflammation of the prostate gland) or sexually transmitted infections (STIs) like gonorrhea or chlamydia can lead to changes in semen color. Infections may also present with other symptoms, such as pain during ejaculation, discomfort in the pelvic area, or unusual discharge.

2. Inflammation: Inflammation of the prostate or seminal vesicles can also result in changes to semen color. This may be accompanied by symptoms like pelvic pain, difficulty urinating, or changes in urinary frequency.

3. Semen Quality: Changes in semen color can sometimes reflect issues with semen quality. For example, a higher white blood cell count in the semen, often due to infection or inflammation, can lead to a yellowish tint.

4. Other Medical Conditions: In rare cases, yellow-green semen could be associated with more serious conditions, such as liver disease or jaundice, which can affect the color of bodily fluids due to the presence of bilirubin. However, this is less common and would typically present with other symptoms, such as yellowing of the skin or eyes.


Symptoms to Monitor
If you notice a change in the color of your semen, it's essential to monitor for any accompanying symptoms. These may include:
- Pain or discomfort during ejaculation or urination
- Unusual discharge from the penis
- Swelling or pain in the testicles or pelvic area
- Changes in urinary habits, such as increased frequency or urgency

When to Seek Medical Attention
If the yellow-green coloration persists for more than a few days, or if you experience any of the concerning symptoms mentioned above, it is advisable to consult a healthcare professional. A doctor may perform a physical examination and recommend tests such as a semen analysis or urine tests to determine the underlying cause.


Conclusion
In summary, while occasional changes in semen color can be normal and often benign, a persistent yellow-green color should not be ignored. It may indicate an infection or other medical condition that requires attention. Early diagnosis and treatment can help prevent complications and ensure reproductive health. If you have any concerns, don't hesitate to reach out to a healthcare provider for a thorough evaluation.
