During the first five days of clomifene therapy, one or more ova will start to mature inside the follicles in the ovaries. The clomifene stimulates the anterior pituitary to release more FSH, which promotes the growth of these follicles. Additionally, as the follicles develop, they release estrogen, which provides feedback to the pituitary gland.
