I took doxycycline for what my urologist said was an infection causing blood in semen. it was good for about a week and a half and then returned. any suggestions on what to do next would be awesome. thanks so much?

It is important to know what kind of urogenital infection you have had and what the organism is. In daily practice, blood in the semen (hemospermia) is not often caused by a urogenital infection. Take care.

Another round of an antibiotic perhaps cipro (or related group) for a longer period might help. If persistent it might necessitate further testing. Hope you do well;
