That is, if I as a male was to eat a Brazil nut and then have unprotected sex with someone with a Brazil nut allergy, my semen will trigger their allergy. Somehow, the allergen manages to survive both digestion and the immune system, and ends up in semen.
Now, as I said, we only have one case study to work on and even then, the case study does raise some interesting questions. How much of it, for example, was psychosomatic? Who knows? All I'm saying is... who wants to do an experiment?
