title: Additional pathway of transfer of uterine prostaglandin F-2 alpha to the ovary in sheep.
abstract: The concentration of prostaglandin (PG) F-2 alpha was measured in different uterine and ovarian blood vessels between Days 12 and 16 of the oestrous cycle in 14 normal ewes. Concentrations of PGF-2 alpha significantly higher than peripheral levels were found in the uterine vein (P < 0.002) and oviducal vein (P < 0.002). This suggests that an additional pathway for PGF-2 alpha transfer to the ovary exists via the venous drainage passing alongside the oviduct.
