A few months ago I had what I felt was cystitis - it hurt to pee and my ejaculation was painful. The ejaculate was also yellowish and smelly, I mean I could tell the difference from my normal performance.

I went to the doc and he said he could treat it one of two ways. I can't remember the first, but the second - which I went for - was to treat the symptoms. The capsules I took cleared up the discomfort but I've noticed now that when I ejaculate there's hardly anything as compared to before.

I have read about a condition where the valve that prevents retro ejaculation into the bladder fails. I can't see how what I had or what I took to clear it up could cause something like that, but I'm kinda alarmed by the prospect because there's no effective cure that I can see and the ultimate bottom line is infertility. I don't see how it could be a blockage because I have no problem passing water.

I don't understand. I'm 33 and in pretty good health, but it's just like a switch has been flipped. Any ideas?
