In the present study, the testis, efferent ductule, and epididymis of sheep fetuses were collected at days70, 90, and 120 of gestation and in the newborn lamb. ER alpha (ERα) and ER beta (ERβ) were detected by immunohistochemistry. The results showed that ERβ staining was negative in all of the examined tissues throughout gestation, whereas ERα immunoreactivity was only located in the nuclei of the efferent ductule epithelium. In addition, both ERα staining intensity and the number of ERα-positive cells were higher at day90 of gestation, compared with that at day70 and at birth. These results suggest that estrogen may play important roles in efferent ductule development in sheep fetuses.
