1 The effect of p ‐chlorophenylalanine (PCPA) on the copulatory behaviour of normal and castrated male rats with females in oestrus was studied. 2 Castration 2 months before the experiment completely prevented the increased copulatory behaviour produced by PCPA in normal rats. 3 The administration of testosterone restored the copulatory behaviour in the castrated rats indicating that testosterone is essential for this behaviour.
