Hormone measurements in nonpregnant and pregnant female mice with hyperprolactinemia induced by metoclopramide.

Hormone levels	Nonpregnant		Pregnant
	CTR1	HPRL1	CTR2	HPRL2
Estradiol (pg/mL)	47.2±3.3	39.4±2.1*	84.4±5.6	79.6±6.4
Progesterone (ng/mL)	3.8±0.2	3.4±0.5*	24.5±2.9	26.8±3.6
Prolactin (ng/mL)	37.98±4.2	82.65±5.3*	98.3±15.6	152.12±16.5**

Note: Number of animals=10. Data are presented as the mean ± standard deviation. The p values represent the comparisons between the nonpregnant groups (CTR1 versus HPRL1) and the pregnant groups (CTR2 versus HPRL2 groups): unpaired Student's t test, p<0.05 = significant. The superscripted * indicates significant differences: estradiol levels: *p<0.05 compared to the CTR1 group (nonpregnant); progesterone levels: * p<0.05 compared to the CTR1 group (nonpregnant); prolactin levels: * and ** p<0.05 compared to the nonpregnant group (CTR1) and to the pregnant group (CTR2).
