The plasma membrane was intact in something between 80 and 85 percent of all epididymal spermatozoa. Respiratory rates and motility were clearly below values typical of ejaculated spermatozoa, though sizeable differences were found to exist for both parameters between individual preparations. The endogenous substrates available proved to be sufficient for such low metabolic activity, whereas higher energy turnover required the presence of exogenous substrates, such as lactate, pyruvate or fructose. Respiratory capacity, determined by uncoupling of oxidative phosphorylation in the presence of lactate, was comparable to that of ejaculated bull spermatozoa. The above findings are likely to suggest that the lower respiratory rates of epididymal spermatozoa were attributable to the fact that their consumption for motility of adenosine triphosphoric acid (ATP) was lower than that of ejaculated spermatozoa.</p>","PeriodicalId":8263,"journal":{"name":"Archiv fur experimentelle Veterinarmedizin","volume":"44 4","pages":"533-41"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13393579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
