David Lorn Garbers (March 17, 1944 – September 5, 2006) was an American scientist who primarily researched reproductive biology, particularly the communication between egg and sperm cells.
David Lorn Garbers was born on March 17, 1944, in La Crosse, Wisconsin,[1] where he grew up on his family's farm.
[1] After graduating from West Salem High School,[1] he attended the University of Wisconsin for his undergraduate, receiving a bachelor's in animal science in 1966.
[2] One of Garbers's key findings in reproductive biology was that caffeine stimulated hyperactive motility in mammalian sperm cells by elevating cyclic adenosine monophosphate (cAMP).
The peptides also served as chemoattractants, drawing the sperm to the eggs, by elevating cellular levels of cyclic guanosine monophosphate (cGMP).
