    Bilateral lesions of the hypothalamic ventromedial nucleus (VMN) effectively eliminated the induction by estrogen-progesterone of lordosis behaviors 4 to 6 weeks after the brain surgery. However, recovery of the lordosis response was clearly evident in the rats with effective VMN lesions 2 weeks after the first test. This suggests that the VMN may not be essential to the expression of hormonally induced lordosis behavior, but may be involved in a supplemental lordosis mediating mechanism.
