Serial PGF2 α Injections Prevent Luteinization of Experimentally Induced Hemorrhagic Anovulatory Follicles

Hemorrhagic anovulatory follicles (HAFs) result in missed breeding opportunities and prolonged or unpredictable interval to subsequent estrus. Serial PGF2 α administrations beginning 12 hours from normal ovulation can prevent luteal formation (Coffman et al. Theriogenology 2014; 82:1241-1245). To investigate whether this protocol would affect luteinization of HAFs, we hypothesized that in estrous cycles with experimentally induced HAFs, early serial PGF2α administration would prevent luteinization and cause early return to estrus compared to non-treated HAF cycles.
