[New data on olfactory control of estral receptivity of female rats].
Olfactory bulb deprivation increased sexual receptivity in 4-day cyclic female rats on the late afternoon of prooestrus (6-7, p.m.). The proportion of receptive females was higher in bulbectomized (B) than in sham operated (SH) animals. On the contrary the same proportion of B and SH females mated in the evening of prooestrus (10. 30-11. 30 p.m.). An increased lordosis quotient was observed in the B females at either of these two stages of the cycle.
