Summary The fine structure of the nerves of the ovarian stroma of the domestic fowl is described for the first time. In the fowl, the nerves are concentrated upon blood vessels, smoth muscles and mainly, the thecal gland with the steroid-producing cells. Myelinated as well as unmyelinated nerve fibers were observed. Numerous axon terminals representing adrenergic and also presumptive cholinergic nerve fibers are regularly seen in membranous contact with steroid-producing cells. In these axon terminals microvesicles are oriented towards the steroid-producing cells indicating a specialization of the surface from axon-to-cell contact. Evidence has been presented that there is a membranous neuro-humoral contact between the peripheral autonomie nervous system and the steroid-producing cells in the ovary. The present investigation has demonstrated that there is morphologic evidence for a nervous control of steroid-producing cells. The physiological importance of this neuro-humoral contact is discussed.
