Abstract

Three experiments were conducted to investigate if sexual experience affects the behavioural response of male rats to natural oestrus odours and constituent odorants. In the first experiment, 16 male Brown Norway rats were exposed before and after sexual training to four odours (1-hexanol (herb odour), a ketone mixture, and faeces from mares and rats in oestrus) presented one at a time to individual rats during a 30-min test. More penile erections were observed during tests when rats were exposed to the two types of faeces as well as the ketone mixture compared to 1-hexanol, both when sexually naive ( P=0.032) and experienced ( P=0.002). In the second experiment, 30 male rats were tested using a habituation/dishabituation protocol. The rats were able to distinguish the ketone mixture used in Experiment 1 from another single-molecule ketone ( P
