As far as I now, there is no conclusive data to prove that a link exists between ejaculatory frequency and prostate problems. It's speculation at this point, nothing more.

The article is from 2003, I couldn't find anything more recent.
EDIT: This massive 8 year study claims there is no statistically significant correlation between ejaculatory frequency and prostate cancer (they did find that frequent ejaculators had slightly less cancer, but it was not statistically significant)

In my review of the literature, I found a number of studies with conflicting results, many of which were conducted using small populations and some with poor design. If there is a correlation between sexual frequency and prostate cancer, I think it is certainly only a small one. However, only a large, well-designed prospective trial would definitively determine risk.
