## Abstract Estrogen stimulates expression of proenkephalin mRNA in neurons of the hypothalamic ventromedial nucleus, and evidence is accumulating that synaptic release of one of the peptide end products, met‐en‐kephalin, influences events that regulate reproductive behavior. To address the questio
