Pituitary gland responsiveness to LHRH and LHRH neuronal responsiveness to excitatory stimuli are severely impaired in female rats treated neonatally with high doses of androgen.


Treatment of neonatal female rats with androgen renders these animals permanently sterile as adults. Previously, we reported that these androgen-sterilized rats (ASR) do not respond to the positive feedback effects of estrogen by having LH surges. We also reported that this defect might be due to the failure of these animals to show increased hypothalamic… (More)
