Contributor(s): Annalisa Barrelet, Graham Munroe, Janice Sojka, Han van der Kolk

Progesterone

  • Progesterone assay is an essential tool in stud practice.
  • In the non-pregnany animal, progesterone is produced by a functioning corpus lutea.
  • During estrus, plasma progesterone concentrations are <1 ng/ml.
  • After ovulation, plasma progesterone concentrations increase rapidly to maximal values within 6 days, remaining high during the luteal phase (>4 ng/ml) and decline rapidly following regression of the CL around day 14 or 15.
