title: Preliminary studies on cholinergic control of pituitary gonadotrophin secretion in the ewe.
abstract: Administration of neostigmine, a cholinomimetic, to anoestrous ewes diminished the increase in jugular plasma luteinising hormone and follicle-stimulating hormone induced by oestradiol. Intravenous injection of atropine had no effect on the gonadotrophin surge.
