Inflammations, infections, surgeries and scars don't just affect Fallopian tube permeability, causing an obstruction in one or both, but also harm the cilia and their capacity to transport. The cells that coat the inside of the Fallopian tubes also secrete a nutritious mucous which is responsible for nurturing the embryo in the first days after fertilization. This function is often jeopardized. Another problem is the loss of the end of the Fallopian tubes’ ability to go back to the ovary and "embrace it", making it unable to receive the ova it releases. What we often see are Fallopian tubes that are stuck far away from the ovaries, facing in the opposite direction. The issues can be moderate and simply lead to a further delay in getting pregnant. Unfortunately, the lesions are frequently severe and can completely prevent pregnancy.
