Table 2. Covariation of the diurnal patterns of the hormones.

	InhB	AMH	Testosterone
InhB	-	0.06 (p = 0.48)	1.26 (p = 0.001)*
AMH	0.06 (p = 0.48)	-	-0.30 (p = 0.65)
Testosterone	1.26 (p = 0.001)*	-0.30 (p = 0.65)	-
INSL3	0.09 (p = 0.049)*	0.03 (p = 0.43)	0.07 (p = 0.68)

The covariation between time points for each of the testicular hormones were calculated for 20 men using mixed model analysis, and expressed as the covariation β coefficient (p value). Note that the data is normalised to the daily mean, and is therefore independent of the absolute levels of the men’s hormones.
