The data show the changes in the organization of the connections observed in the OVX adult rats that displayed a reduced axonal length for the MPN fibres reaching the VMHvl, suggesting that peripubertal ovarian hormones are relevant to the organizations of MPN connections with structures involved in the promotion of female sexual behaviour.

It is demonstrated that ERα masculinizes GABAergic neurons that gate the display of male-typical behaviors.

The results showed that the administration of E2BSA alone increases the number of PR‐immunoreactive neurons and the expression level of PR protein to values similar to those resulting from E2 administration, providing the first evidence that membrane‐initiated E2 stimulation is able to induce and to potentiate the genomic activation of PR expression in the VMN.

The results suggest that mating activates several distinct VMH neuron types, however, ERalpha-IR neurons are activated to a greater extent compared with the PAG-projecting neurons.

The results are consistent with the hypothesis that endogenous OT is involved in female sexual behavior, and suggest that the source of oxytocinergic innervation to the Oxytocin receptors in the VMN may be neurons in the PVN.

The results suggest that oxytocin may directly influence these lordosis-relevant VMH projection neurons, whereas estrogen may have transsynaptic effects.

Some of the VMHvl neurons that communicate a facilitatory signal to the PAG may also act to stimulate lordosis through a feedback suppression of the net inhibition formed by efferent signals from the forebrain.

- BiologyJournal of neuroendocrinology

Many neurons within the ventrolateral hypothalamus in guinea pigs contain estrogen‐induced progestin receptors as well as substance P and may prove to be components of the neural circuitry underlying a variety of functions influenced by gonadal steroid hormones and substance P, such as female sexual behavior, salt intake, nociception and aggression.

The findings suggest that local estrogenic stimulation of target cells in the VMN is capable of both priming the estrous response and induction of P receptors, and whether these two effects are causally related awaits future study.
