Can a UTI or a prostate infection cause erections to not be as hard/big?  I was diagnosed yesterday by a doctor who said that I have either a UTI or prostate infection.  I started taking the meds for two days, prescribed for 10.  I had asked the doctor if it was safe to have sex (with a condom) and he said yes.  Tonight I had sex, but I noticed that my election was not as hard or as big as normal.  Could this be because of the UTI/prostate infection or should I go back to the doctor?
HI, thanks for using Chat Doctor Any infection or other disorder affecting the genital tract can cause erectile problems. This complication is temporary in most cases, when the infection resolves then this should resolve as well. I hope this helps
