Prostaglandin F-2 alpha and LH release in immature ewes.
The effect of PGF-2 alpha on LH release in immature ewes was studied. One intramuscular injeciton of PGF-2 alpha induced LH release 36-72 h after treatment in 3/4 ewes. The LH variations were not associated with changes in the plasma concentration of progesterone and oestrogens. These results suggest that the LH release in immature ewes is due to PGF-2 alpha acting at central structures.
