[Fructose--its importance to quality of human ejaculate (author's transl)].
No statistically significant differences regarding fructose in one millilitre and ejaculated volume were established from a comparison between 95 ejaculates, among them 14 normospermatic, 47 asthenospermatic, 16 oligospermatic with more than ten million of spermia in one millilitre, six oligospermatic with less than ten million, and twelve azoospermatic. Very low and statistically insignificant correlations, also, were found to exist between the fructose level in a given ejaculate and other qualitative parameters, such as volume, sperm count, as well as morphology and motility of spermia one hour and five hours after ejaculation. The correlation coefficient usually was close to zero. These results seem to cast doubt at the diagnostic value of fructose determination in spermatological routine tests. However, studies into the correlations between fructose, glucose and, perhaps, other sugars in both clinically intact males and patients with metabolic disorders might produce new insights into the dynamics of glucose metabolism in ejaculated semen.
