Oviduct Epithelium

The oviduct epithelium consists of two distinct cell types. The ciliated cells dominate and serve to move the ovum away from the ovary and toward the uterus. The non-ciliated secretory cells, also known as peg cells, release a secretion that lubricates the tube and provides nourishment and protection to the traveling ovum. What hormone determines the extent of cilia formation on the cells of the oviduct?
