Lily of The Valley Phenomenon
See also: bourgeonalThe odor of lily of the valley, specifically the ligand bourgeonal, attracts mammal sperm in a dramatic manner. The 2003 discovery of this phenomenon prompted a new wave of research into odor reception, but no evidence was found that the female sex organ has similar odors of any kind. A 2012 study demonstrated instead that at high concentrations, bourgeonal imitated the role of progesterone in stimulating sperm to swim (chemotaxis), a process unrelated to odor reception.
