The ampulla is the widened segment of the uterine tube located between the infundibulum and the narrower isthmic region. It contains extensively folded mucosa lined by ciliated and secretory epithelial cells. In human reproduction, the ampulla is the most common anatomical location in which a fertilisation-competent spermatozoon encounters the ovulated oocyte. Tubal fluid, epithelial secretions and coordinated muscular and ciliary activity contribute to the local environment supporting gamete interaction. Following fertilisation, the developing zygote and early cleavage-stage embryo are progressively transported from the ampullary region toward the uterus.
