title: Formation of the active antifertility metabolite of (S)-alpha-chlorohydrin in boar sperm.
abstract: The male antifertility agent (S)-alpha-chlorohydrin (I) is metabolized by boar sperm to (S)-3-chlorolactaldehyde (II) by an enzyme that is involved in the oxidation of glycerol to glyceraldehyde. The presence of glycerol decreases the activity of this enzyme towards (S)-alpha-chlorohydrin in vitro thereby preventing the formation of (S)-3-chlorolactaldehyde, an inhibitor of glyceraldehyde 3-phosphate dehydrogenase in boar sperm.
