Notes:
In combination with biochemical determination of cholesterol in testes, cholesterol was studied histochemically in the testicular interstitial cells of dd strain mice from 5 to 63 days.Cholesterol is found in interstitial cells at five days and cholesterol positive interstitial cells increase significantly from 7% at 5 days to 47% at 21 days (17% at 7 days, 21% at 10 days and 31% at 14 days) and thereafter gradually to 58% at 63 days (50% at 28 days, 54% at 35 days, 56% at 42 days, 58% at 49 days and 57% at 56 days).The cholesterol concentration of testes (μg of cholesterol per mg testicular weight) remains at low values before 42 days (1.33 at 5 days, 2.12 at 7 days, 1.89 at 10 days, 2.18 at 14 days, 2.16 at 21 days, 1.63 at 28 days and 2.09 at 35 days) but it increases rapidly at days 42-49 (2.21 at 42 days and 5.16 at 49 days) and then it is almost unchanged (5.47 at 56 days and 5.18 at 63 days).From these results it is suggested that (1) at five days testicular steroid could be elaborated and (2) the capacity of interstitial cells to produce testicular steroid elevates actively from 42 to 49 days.
