What can cause semen to turn black on contact with water?

Hello,

Welcome to icliniq.com.

I read your query and understand your concern.

There could be several potential explanations for the presence of black particles in your semen, such as:

1. Blood: If blood mixes with semen, it can cause discoloration and give the appearance of black particles. It is possible that a small amount of blood is present in your semen, even though it may not have been detected during the semen analysis.

2. Medications or supplements: Certain medications or supplements may cause changes in the color or appearance of semen.

3. Infection.

I would like to suggest you kindly attach the photo of black semen to help you further.

I hope this has helped you. Thank you.
