Endometrial estrogen and progesterone receptors in a uterus didelphys

A 23-year-old woman with a uterus didelphys and a totally occluded left tube had a hysterectomy one year after having a child. Endometrial estrogen and progesterone receptors, both cytoplasmic and nuclear, were determined in five longitudinal sections of each horn. The amount and distribution of these receptors were normal, but the receptor content of the right horn was higher than that of the left.
