Urology/hematospermia with avodart


good morning, i am a 48 yo man and have been taking propecia and then avodart for hair loss since over 10 years. ( last 6 years on avodart).
I am experiencing hematospermia on and off when on the medication... and funny enough, no symptom when i take a break from the medication.
I read from different blogs that avodart is actually the recommended treatment for hematospermia. I am curious because in my case it seems to be the actual cause (or at least related to symptom).
I wanted to ask you if you had heard of similar symptoms from other patients ?
Would recommend other actions in my case ? change of medication or may be laser surgery ?
I would like to hear more about that laser procedure and would consider it if appropriate.

many thanks


There is no scientific explanation for hematospermia that is associated with avodart.  As you mentioned, we use Avodart as one of the therapies for hematospermia.

Since hematospermia is not dangerous and tends to be self-limited, we usually just ignore it.  If it remains for 3 months or more, then we might consider looking into it.  

There is no role for laser surgery for hematospermia.  The bleeding that occurs in hematospermia is inside the seminal vesicles.  There is no access to this area for surgery without a major open procedure that is typically done only for known prostate cancers.

If you are being told this, please seek another opinion.
