Group (n=10)	Testosterone (ng/ml)	17β-Estradiol (pg/ml)
Tap water control	7.44 ± 9.94	37.32 ± 8.67
80 ppb MTBE	2.00 ± 3.79	35.89 ± 8.97
800 ppb MTBE	9.83 ± 15.47	36.50 ± 20.29
8000 ppb MTBE	12.50 ± 17.15	32.50 ± 10.10

Note: Mice were exposed from PND 25–26 to PND 76–77. Values in table are mean ± standard deviation; n=10. No statistically significant differences were observed across the groups (p>0.05).
