Glucose metabolism in the testis of the normal and streptozotocin diabetic rat

In the present work, the metabolism of [U-14C]glucose was studied in the testicular tissue of normal and streptozotocin diabetic rats. The results show that diabetes alters 14CO2 production and 14C incorporation into lipids from [U-14C]glucose. No differences were found in the [14C]proteins and [14C]nucleic acids between experimental groups. Results are discussed in relation to an insulin deficiency and/or an alteration in the hypothalamic-hypophyseal-gonadal axis.
