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.

“As I went forth early on a still and frosty morning, the trees looked like airy creatures of darkness caught napping; on this side huddled together, with their gray hairs streaming, in a secluded valley which the sun had not penetrated; on that, hurrying off in Indian file along some watercourse, while the shrubs and grasses, like elves and fairies of the night, sought to hide their diminished heads in the snow.”
—Henry David Thoreau (1817–1862)
