According to the University of California San Francisco (UCSF) Medical Center, an egg takes about 30 hours to get down the Fallopian tube. The trip starts when the egg is let loose by the ovary.
UCSF Medical Center reports that a released egg is swept into a Fallopian tube by finger-like protrusions, or fimbriae, located at the end of the tube. Hair-like cilia in the tube then push the egg along. As the egg moves, muscles contract and contribute to its progress. The process is impeded or prevented by certain medical conditions, such as endometriosis and pelvic infections. These conditions sometimes cause scarring or damage to the tube.
