Plate I.

Progesterone receptor staining of Sahel goat uteri during first trimester (day 28 of gestation). Arrow heads indicate moderate positive progesterone receptor (PR) staining (2+) and eosinophilic cells while arrow indicates strong positive staining (3+) for progesterone receptors (PR) and endometrial lymphocyte. Plate Ia (Control goat): Progesterone receptor staining indicated moderate positive staining (2+) in the stromal, luminal and glandular epithelia cells (IHC × 100). Plate Ib (Dexamethasone treated goat): Progesterone receptor staining showed strong prositive staining (3+) in the glandular epithelia cells, moderate positive staining (2+) in the stromal and luminal epithelia cells (IHC × 100)
