Pollen isn't just the stuff that coats our windshields with a fine powder and makes some of us sneeze uncontrollably in the warm weather months; it's also pure male sex.
The birds and the wheeze, if you will.
Pollen is ``tiny little grains which represent the male half of the fertilization process,'' said Dr. Michael Phillips, a professor, clinician and researcher at the University of Pennsylvania's allergy and immunolgy department. ``It's spread to the female half, where fertilization takes place. It's very analogous to the human process.''
