[Relation between spermatozoids and reducing sugars (glucose and fructose) in human seminal fluid].
The prostatic fraction of seminal plasma contains components that are involved in the process of transforming fructose into glucose. If a positive correlation can be found between the slope of the decrease of fructose (estimated to be between 30 minutes and 5 hours) and the sperm count, with at the same time the maintenance of a relatively constant glucose level, then we have been able to demonstrate that glucose is more efficient than fructose to keep spermatozoa mobile. The enzyme process involved in transforming fructose into glucose may thus act to maintain definite glyspermia with a maximum value of 1.8 g/l. Aspermia in some circumstances then can be related to the absence or poor function of the transformation process and thus with the absence or decrease in prostatic secretion.
