Abstract
The goal of this study was to assess the contributions of the most important acid glycosidases to the processes connected with testes involution (in the summer) and spermatogenesis during the reproductive season (the spring) in ganders. Statistically significant increases in the specific activity of N-acetyl-β- d-hexosaminidase, α- d-galactosidase, β- d-galactosidase, and α- l-fucosidase during the period of testes involution were detected. α- d-galactosidase, β- d-galactosidase, and α- d-glucosidase showed an increase in the relative contribution of those multiple forms which are characterized by less acidic values of the p I during the reproductive season. It is suggested that the observed increases in the specific activity of β-HEX, α-GAL, β-GAL and α-FUC may be connected with the catabolism of glycoconjugates, when the spermatogenic activity of the testes declines. The increases in the relative contribution of less acidic forms of α-GAL, β-GAL, and α-GLU during the reproductive season may be linked to the rise in the number of spermatocytes, spermatids and spermatozoa during spermatogenesis.
