Hysterectomy is known to increase the life-span of the CL in several mammalian species (Dobrowolski & Hafez, 1971; Anderson, 1973) and the involvement of prostaglandins has been suggested (Pharriss, 1970; McCracken, Baird & Goding, 1971). Total hysterectomy in the rabbit extends the life of the CL (Asdell & Hammond, 1933) and exogenous prostaglandins cause luteolysis (Duncan & Pharriss, 1970). Few detailed studies have been reported on the vasculature of the rabbit ovary and the present investigation was carried out to determine whether anatomical prerequisites exist for a local uterine control of luteal function.
Two groups of female albino Swedish Land rabbits, 5 to 6 months old and weighing 2·3 to 3·0 kg, were studied. The first group (four animals) consisted of untreated animals that had not
