What is ampulla of oviduct?

The ampulla of the oviduct, also known as the ampulla of the fallopian tube, is a region within the female reproductive system where fertilization typically occurs. It is the widest part of the oviduct, situated between the infundibulum and isthmus. The ampulla is characterized by its muscular walls and a highly folded mucosal lining, which helps facilitate the movement of the egg and sperm, as well as the early development of the embryo before it moves to the uterus.
