	PND	CON	NP-50
Anogenital distance (mm)	35	18.6±0.38	18.3±0.33
	40	19.4±0.32	19.4±0.24
	45	20.1±0.29	20.1±0.20
	50	20.8±0.23	20.9±0.15

Values are expressed as mean±SE (n=9).

NP, nonylphenol; PND, postnatal day; CON, control group provided with tap water only NP-50, treated with nonyl­phenol at a dose of 50 μg/L.
