1. The lipids and @entity1718 of the lipids of testes of @entity35 aged 4 weeks to 6 months were separated and analysed. 2. A decrease in concentration of @entity412 was noted, but there was no significant change in the concentration of phospholipids, plasmalogen or @entity165 during this time. 3. There were no significant differences in the total lipid concentration of @entity7609 , @entity3106 , @entity4722 , @entity1426 and @entity71943 between the various age groups. 4. A decrease in the concentration of @entity3952 in the phosphatide and @entity412 fractions and an increase in the concentration of @entity23165 (characterized as the @entity21316 ,7,10,13,16-isomer) in @entity36150 but not in @entity412 were observed during the maturation period. 5. Histological studies indicated that the lipid changes occurred at the same time as the appearance and maturation of the spermatids.
