The fallopian tube plays an important role in the process of conception, facilitating egg collection, fertilisation and embryo transport. Tubal fimbriae guide the ovulated egg into the tube. Unidirectional beating of the tubal cilia and peristaltic contractions of the muscular tubal wall transport the egg and then embryo. Secretions from the tubal epithelium nourish the embryo.
Tubal factor subfertility includes an array of disorders affecting one or more of the above components, including peritubal adhesions, proximal and/or distal tubal blockage and hydrosalpinx formation. Even in the presence of a patent tube, damage to the inner microarchitecture may result in severe impairment of tubal function.
Tubal factor subfertility accounts for approximately 20% of subfertility. It is one of the preventable causes of subfertility.
