Clomifene	$6.21\times {10}^{-7}$	$2.55\times {10}^{-7}$
Ketoconazole	$5.98\times {10}^{-7}$	$2.46\times {10}^{-7}$
Valproic acid	$5.03\times {10}^{-7}$	$2.07\times {10}^{-7}$
BPS	$8.64\times {10}^{-6}$	$3.55\times {10}^{-6}$

Theophylline	$3.67\times {10}^{-8}$	$1.69\times {10}^{-8}$
Mixture III effect		53% reduction in the testosterone production

Note: ${\text{EC}}_{20}$ is the concentration (M, $\text{mol}/\mathrm{L}$) of each substance associated with a 20% reduction of testosterone production. Mix, mixture.
