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.''
