Hello!
According to recent studies, gold nanoparticles play a negative role on male fertility (reducing the motility of sperm cells, among other things),
So, the question is, is the amount of gold absorded from donning gold jewerly enough to have noticeable spermatotoxic effects?

Probably not.
The dangers/properties of nanoparticles are very different from that of bulk materials. Carbon nanotubes are very nasty and need to be handled very carefully whereas a lump of charcoal is not nearly as bad. It is not the material itself that is dangerous: it is the combination of size and shape.
Another example is asbestos which is a silicate material which is the most common class of materials on earth. Fortunately, most of them are not nearly as dangerous as asbestos.

Also, making gold nanoparticles is not straightforward even in the lab; I doubt any could spontaneously form from a piece of jewellery under normal circumstances.
Gold is extremely inert and should be one of the safest materials to use for jewellery.

Gold has been used in dental applications a long time: since 1530, for example. The Etruscans used gold wire to hold replacement teeth in place.

I can’t really add too much. I know there’s been a fair amount of work linking nanoparticles of many materials with varying degrees of cytotoxicity, so it’s not much of a stretch to believe that gold nanoparticles could affect fertility. But as others have pointed out, gold jewelry is not a source of gold nanoparticles, so there’s not much to worry about there.
