Table 3. The Effects of DMP Exposure on the Serum Progesterone and Estradiol in Female C57 Mice^a.

Treatment	Progesterone, μmol/L		Estradiol, pmol/L
	20 Days	40 Days	20 Days	40 Days
Control	38.15 ± 2.89	33.82 ± 2.35	109.49 ± 7.29	183.60 ± 7.48
DMP, g/kg
0.5	42.84 ± 3.31	33.03 ± 1.48	103.11 ± 7.43	210.14 ± 3.56b
1	37.56 ± 3.07	34.06 ± 3.16	103.97 ± 9.15	195.48 ± 10.23b,c
2	38.57 ± 2.74	36.08 ± 2.67	94.47 ± 7.80	196.59 ± 8.58b,c

^a The data are presented as mean ± SD; n = 5 for each group. The effect of DMP was analyzed by one-way analysis of variance (ANOVA) and post hoc testing by the Games-Howell test (for heterogeneous group variances).

^b Significantly different from control (P < 0.05).

^c Significantly different from 0.5 g/kg/d (P < 0.05).
