| Abstract: | The epididymis of adult rams is the primary source of alpha-glucosidase in seminal plasma. Two breeds of rams were selected to ascertain whether the enzyme was under androgenic control during adult life of rams. Opposite variations between serum testosterone and alpha-glucosidase were recorded over a period of 16 months in Suffolk and Finnish Landrace. In addition, the highest percentage of sperm motility was associated with a low alpha-glucosidase content of seminal plasma. Data from this study suggest that seasonal variations of testosterone in adult rams exert a negative control on the presence of alpha-glucosidase in semen. |
