[Effect of total fasting on testicular lipid fractions in rats].

Rats weighing 290 g each were fasting for 12 days with no changes occurring in the weight of the testicles, total lipids, phospholipids, di- and triglycerides content therein. The cholesterol ethers level increased by 53 per cent and in the composition of di- and triglycerides and the cholesterol ethers the relative content of high-molecular polyunsaturated fatty acids was going up, while the fatty acids composition of the phospholipids remained the same.
