Hello, Welcome to HCM, I am Dr. Das
Firstly, blood in sperm is not a disease. It is a feature of some other disease. Most commonly infection of the lower urinary tract
or genital tract can present with this feature.
At this stage, it definitely affects the sperm motility
and other factors, and leads to infertility
. But, if you take antibiotics and other medications, then it will be normal.
So, continue the drugs and keep following up with the doctor.
