Understanding Ovum Transport: How the Fallopian Tubes Move the Egg

The ovum is transported along the fallopian tube by a process called ciliary action. The cilia, which line the fallopian tubes, are finger-like projections that beat in waves. These waves, which are similar to the waves caused by a fanning motion, help move the ovum toward the uterus.

In addition to ciliary action, the fallopian tubes also contract and relax. These movements, which are stimulated by hormones, help move the ovum along the fallopian tube toward the uterus. The ovum will usually take 24 hours to travel from the ovary to the uterus.
