Abstract:
Adult Levant vole (Microtus guentheri) females, which at the age of 1 or 4 days had been in direct contact for 2 h with filter paper impregnated with a suspension of diethylstilbestrol dipropionate (DES) in soybean oil (0.125 mg DES/cm2), or whose nursing mothers had been in similar contact with DES during that period, were found to be sterile in the overwhelming majority of cases. Females slightly older (5-6 days old) at the time of such contact with DES (direct, or through their nursing mothers) retained their fertility. © 1984 Springer Science + Business Media B.V.
