Twenty-seven yearling rams were subjected to elevated temperature for 0 (control), 1 or 2 weeks in a temperature controlled room. Testis weight decreased with increasing length of exposure time and histological sections showed progressive degeneration. Total lipid, triglyceride and total and free cholesterol concentrations increased after 1 week of treatment but returned to control concentrations after 2 weeks. Total amounts of all lipid components, except esterified cholesterol, decreased as testis weight decreased.In vitroincorporation of sodium acetate-1-14C into esterified cholesterol, esterification of cholesterol-4-14C and catabolism of cholesteryl-4-14C-stearate were all increased by heat treatment. Testis tissue from treated rams catabolized cholesterol-4-14C more slowly in vitrothan that from control rams. |
