Abstract

The cholesterol concentration in the testis exhibits a parallel seasonal fluctuation with spermatogenic activity. The absolute cholesterol content of the testis is high during the period of active sperm production from November–December to April-May while it is low during the period of quiescence in June-July. When testis cholesterol concentration is calculated as mg% of its weight, low values are recorded in the spermatogenically active period when testis weight is high. But the value is elevated during reproductive quiescence when the testis weight is low. This suggests that there is an intense mobilization of cholesterol in the mature testis when synthesis of steroid hormones is increased. A minimal level of cholesterol in the body is maintained throughout the year, except during July, August and September when both total and esterified cholesterol values are high presumably due to marked increase in dietary intake.
