Well, the two sentences following your quote read:

> 2. As regards sperm DNA defects, caffeine intake seemed associated with aneuploidy and DNA breaks, but not with other markers of DNA damage > 3. Finally, male coffee drinking was associated to prolonged time to pregnancy in some, but not all, studies.

And then goes on to conclude:

> The literature suggests that caffeine intake, possibly through sperm DNA damage, may negatively affect male reproductive function.

The whole abstract points at weak/inconclusive results, but we're definitely talking about caffeine here, not sugar.
