Figure 1

Body and scrotal surface temperatures of mice before and during heat treatment. The table showed the body and scrotal surface temperatures of each mouse before (A) and during (B) heat treatment, as measured one time using a thermal imaging camera. (C) Mouse body surface temperatures were measured before and during heat treatment on days 1, 2, 4, 8 and 12. Average body surface temperature was achieved by counting the average of body surface temperatures of five mice, paired t-test, body surface temperature during treatment vs. before treatment, * P < 0.05. (D) Mice scrotal surface temperatures were measured before and during heat treatment on days 1, 2, 4, 8 and 12. Average scrotal surface temperature was achieved by counting the average of scrotal surface temperatures of five mice, scrotal surface temperature during treatment vs. before treatment, * P < 0.05. T, testis. Each bar represents the mean ± SEM (n = 5).
