Sexually immature female rats were either primed with estradiol benzoate on day 23 or given daily injections of various androgens on days 23--25. Plasma for LH and FSH determinations was collected on day 26, 5 h after an injection of progesterone. Ma

Precocious activation of the pituitary-gonadal axis was induced in immature rats by unilateral electrochemical stimulation of the basal hypothalamus on day 23 of life. In response to this brain stimulus, about 50% of animals ovulated prematurely on e

An investigation of pituitary sensitivity, assessed in terms of increments in plasma LH and FSH concentrations, to stimulation with one or two injections of gonadotrophin releasing hormone (GnRH) was carried out on 26-day-old immature female rats whi

1. Ovulation was induced in Nembutal-blocked pro-oestrous rats by electrical stimulation of the hypothalamus. 2. The same type of electrical stimulation was applied during the collection of hypophysial portal blood. 3. Pooled hypophysial portal plasm

1. The milk-ejection response in lactating rabbits has been used to study the effect of electrical stimuli of different types applied to the supraopticohypophysial tract in the pituitary stalk. 2. Sine-wave alternating-current pulses were compared wi

Ovariectomized rats were injected with 12 μg estrogen and 30–32 hr later treated with 0.1 μg ACTH, 1.0 μg progesterone or 10 IU chorionic gonadotropin. Lordosis responses occurred following the ACTH or progesterone treatment only. Assays of syst

1. Isolated rat neurohypophyses were studied in vitro and the hormones released on electrical stimulation of the pituitary stalk or on exposure to excess potassium were estimated by a milk-ejection assay. 2. The stalk was stimulated with trains of 50
