Abstract

The rabbit corpus luteum contains a cytoplasmic estrogen receptor substance in concentrations comparable to those found in the uterus. Receptor in corpora lutea of nonpregnant rabbits was highest at midluteal phase and decreased before physical regression of corpora was evident. These results support the view that the corpus luteum in this species is an estrogen-responsive tissue.
