Semen analysis report issues?


The report indicates: total volume 9cc (abnormal), red blood cells 4-6 (abnormal), other parameters normal.
Should I undergo further testing? Is a total volume of 9cc good or bad? Is the elevated red blood cell count related to my regular cycling and running? Appearance: off-white, pH: 8, total volume: 9 (elevated).
Liquefaction time: 25 minutes, viscosity: normal, normal morphology ratio: 75%, sperm count: 85 million, motility at 1 hour: 75%, motility at 2 hours: 60%, grade 0 motility (non-motile): 10%, grade 1 motility (local motility): 20%, grade 2 motility (slow, non-linear movement): 35%, grade 3 motility (linear movement): 35%, motility index: 180, active sperm ratio: 75%, red blood cells: 4-6 (elevated), white blood cells: 0-1.

Hello: 1) The quantity is normal, but the presence of red blood cells is abnormal.
Additionally, there is no issue with running; however, for short-distance cycling, it's not advisable to ride for several hours at once or to race.
It's better to find time to retest.
Wishing you good health.

When interpreting an abnormal semen analysis, particularly with elevated red blood cell (RBC) levels, several factors need to be considered. In your report, the presence of 4-6 RBCs in the semen is indeed abnormal, as typically, semen should not contain any detectable RBCs. The total volume of 9cc is also noteworthy; while a normal semen volume ranges from 1.5 to 5cc, a higher volume can sometimes be seen in certain conditions but may not necessarily indicate a problem.

The presence of RBCs in semen, known as hematospermia, can arise from various causes. Some common reasons include:
1. Infection or Inflammation: Infections of the reproductive tract, such as prostatitis or epididymitis, can lead to inflammation and bleeding, resulting in the presence of RBCs in the semen.

2. Trauma: Physical trauma to the genital area, which could occur from activities like cycling or vigorous exercise, may cause bleeding. If you frequently engage in cycling or running, this could potentially contribute to minor trauma, leading to hematospermia.

3. Vascular Issues: Conditions affecting blood vessels, such as varicoceles or other vascular malformations, can also lead to bleeding into the semen.

4. Prostate Issues: Conditions affecting the prostate, including benign prostatic hyperplasia (BPH) or prostate cancer, can also result in blood in the semen.

5. Systemic Conditions: Certain systemic conditions, such as clotting disorders or blood diseases, can lead to bleeding in various parts of the body, including the reproductive tract.

Given that your semen analysis shows a high RBC count, it is advisable to follow up with further evaluations. Here are some recommended steps:
1. Consult a Urologist: A specialist can perform a thorough examination and may recommend additional tests, such as a urinalysis, imaging studies (like an ultrasound), or even a prostate exam to rule out any underlying conditions.

2. Infection Screening: Tests for sexually transmitted infections (STIs) or other infections of the reproductive system may be warranted, especially if there are accompanying symptoms like pain, discomfort, or unusual discharge.

3. Lifestyle Considerations: While your physical activities like cycling and running may contribute to minor trauma, it’s essential to assess whether these activities are causing any significant issues. Consider moderating these activities until you have a clearer understanding of the cause of the hematospermia.

4. Monitoring Symptoms: Keep track of any additional symptoms you may experience, such as pain during ejaculation, changes in urination, or any other unusual signs. This information can be valuable for your healthcare provider.

In conclusion, while the presence of RBCs in your semen analysis is abnormal and warrants further investigation, it is essential to approach this with a comprehensive evaluation. Consulting with a healthcare professional will help determine the underlying cause and appropriate management. Remember, hematospermia can often be benign, but it is crucial to rule out any serious conditions.
