A total of 31 male volunteers aged 18-64 participated in this study. Dr. Alan Hess, director of the foundation, selected 24 foods or aromatics with strong flavors. During the test, volunteers were asked to smell these 24 smells in sequence while standing in front of a special scanner to record changes in blood flow to their sexual organs. The results showed that blood flow to the male penis increased significantly when smelling pumpkin. Especially when mixed with the smell of lavender, 40% of the men tested became sexually aroused. If pumpkin is made into fried donuts and sprinkled with some chocolate, 20% of men will be "sexually excited".

“The aroma of food reminds us of the pleasure between our lips and teeth when we taste it, or the good intentions of our lover when making it. This feeling is mixed with love, family affection and satisfying appetite.” Hess said.
