[Fructose in ejaculate--correlation with age of proband (author's transl)].

No significant correlation was found to exist between the age of 95 males and fructose level in one millilitre of each one's ejaculate (correlation coefficient 4 = -0.139) nor between proband age and fructose level by volume of ejaculate (r = -1.141). Yet, fructose levels in ejaculate of men below 30 years of age tended quite often to be higher than those recorded from ejaculate of men above 40. The ejaculates tested were different in quality. Close and statistically important negative correlations between proband age and total fructose in ejaculate (r = -0.620) were recordable only from men with excellent average spermatozoan motility, one hour from ejaculation and not even largely reduced after another five hours.
