The concentration of prostaglandin (PG) F-2alpha in ovarian arterial blood was compared to that in aortic and carotid blood at different stages of the ovine oestrous cycle, and its concentration measured in the ovarian artery following the infusion of radioactive PGF-2alpha to the uterine vein. In all cases the concentration of PGF-2alpha increased during passage through the ovarian artery, and the increase was proportional to the log of the concentration in the uterine vein. No such change was observed in the concentration of progesterone in the ovarian artery or of PGF in the uterine artery. It was concluded that PGF-2alpha can be and is normally transferred from the uterine vein to the ovarian artery. These results are compatible with the hypothesis that PGF-2alpha of uterine origin is the normal luteolytic agent in the sheep.

Ovarian venous, ovarian arterial and uterine venous blood were collected from the same side as a corpus luteum in 10 nonpregnant and 10 pregnant ewes at day 15 postestrus. Both ovarian and uterine venous samples were collected by venipuncture. Ovarian arterial blood was collected into heparinized centrifuge tubes after a small portion of the artery was dissected free from mesovarium and then severed. Arterial blood flow was estimated by timed collection. Ovaries and corpora lutea were removed, frozen in .vials placed in liquid nitrogen, weighed and stored at-20 C. Prostaglandins F (PGF) in plasma and tissue were quantified by use of radioimmunoassay. Nonpregnant. and pregnant ewes did not differ in concentration (ng/ml) of PGF in plasma from uterine veins (7.1 + 3.4 and 5.2 + .9), ovarian arteries (.6 + .3 and 1.1-+ .3) or ovarian veins (.6 + .1 and .8-+ .3). The rate of blood flow from the severed ovarian artery was higher (P<.05) in the pregnant ewes (4.2-+ 1.6 vs .9 + .2 ml/min). The quantity of PGF apparently being transported to the ovary in arterial plasma was higher (P<.05) in pregnant (2.1-+ .5 ng/ml) than in nonpregnant ewes (.5 + .2 ng/min).
