How the Egg Crosses the Gap to the Tube
The fallopian tube does not form a sealed passage from the ovary. When ovulation releases an egg, the egg enters the fluid-filled space of the pelvis, usually still surrounded by a cluster of support cells called the cumulus. The tube’s fringed fimbriae move near the ovary, helping guide that small, delicate cluster toward the tube’s opening.
A Moving Surface, Not a Tiny Grab
The fimbriae do not seize the egg like fingers. Their movement helps position the tube’s opening, while microscopic hairlike structures called cilia beat along the tube’s lining. Their coordinated motion creates currents that help carry the egg inward; gentle contractions of the tube’s muscular wall also contribute to transport.
Once inside, the egg travels through the tube toward the uterus. Fertilization commonly occurs along this route, so the tube must do more than provide a doorway: it also moves the egg and, if sperm are present, brings the two into the same passage. The gap between ovary and tube makes egg pickup an active process, not an automatic slide into a connected channel.
