  • Title: [Fructose and citric acid content in the sperm of stud males with forms of impotencia generandi].
    Author: Doĭcheva M.
    Journal: Vet Med Nauki; 1979; 16(10):48-54. PubMed ID: 44928.
    Abstract:
    Fructose and citric acid content was investigated in the sperm of 27 bulls with anamnesis data for "low quality sperm". The bulls were used as breeding males in various stations for artificial insemination. Three forms of Imp. generandi are described and several grades of Oligokinospermia are differentiated. Changes in fructose and citric acid quantity differed in degree in the various forms of Imp. generandi described. Fructose and citric acid value in I and II grade Oligokinospermia were insignificantly lower than the low limit of these indices observed in bulls with normal spermoproduction. Correlation between the changes observed is positive, slight, insignificant or entirely missing. Fructose content is insignificantly lower in cases of III and IV grade Oligokinospermia and in Akinospermia, while citric acid content is reduced only in Akinospermia. The correlation between the changes is positive , high and significant. Fructose reduction in bull's semen below 400.0 mg% and of citric acid below 500.0 mg% in case of negative data for inflammatory changes in vesiculae seminalis is a diagnostic symptom for disfunction of vesiculae seminalis. More considerable changes occur in fructose values.
