Beobachtungen zur Beschleunigung der Geschlechtsreife junger Mäuseweibchen durch die Gegenwart adulter Männchen und durch exogenes Oestrogen

Summary The influence of the presence of adult males on the acceleration of sexual maturation of female mice was examined under various experimental conditions and compared with the influence of exogenous oestrogen. The criteria of sexual maturation were not equally influenced. It is concluded that sexual maturation is a complex feature and that acceleration of single criteria does not signify sexual maturation.
