These investigators collected axillary secretions on gauze pads taped beneath the arm of a woman who had a record of regular 28-working day menstrual cycles along with a “prior working experience of ‘driving’ An additional woman’s menstrual cycle on three separate situations, above three consecutive yrs; i.e., a buddy had grow to be synchronous along with her once they roomed collectively in the summer and desynchronized after they moved apart in the fall.” The pads had been Reduce into 4 squares, coupled with four drops of 70% Liquor, and frozen in dry ice.
