Anatomical terminology

The fallopian tubes (also known as oviducts and uterine tubes) connect the ovaries to the uterus, and let the ovum pass into the uterus where they are able to be fertilized by sperm during sexual intercourse.There are two Fallopian tubes attached to either side of the uterus.[1]

Origin[change | change source]

They are named after the 16th century Italian anatomist, Gabriele Falloppio. The Greek word salpinx (σαλπιγξ) means "trumpet".

Anatomy[change | change source]

There are two Fallopian tubes attached to either side of the end of the uterus. Each tube will end near one ovary. This place is called the fimbria. The Fallopian tubes are not attached to the ovaries, but open into the peritoneal cavity.

In humans, the Fallopian tubes are about 7 - 14 cm long.

Parts[change | change source]

There are four parts of the fallopian tube from the ovary to the uterus:[2]

  • The fimbria
  • Infundibulum
  • Ampulla - where the ovum is fertilized
  • Isthmus

Layers[change | change source]

The fallopian tube

The fallopian tube is made of three layers:[3]

Movement[change | change source]

The Fallopian tubes can move around the pelvis.

Fertilization[change | change source]

When an ovum is ready to be released from the ovary, the ovary wall breaks open and the ovum goes into the fallopian tube. There, it starts moving towards to uterus with the help of liquids and cilia on the inside walls. This can take hours or days.

If the ovum is fertilized while in the fallopian tube, then it sticks to the endometrium, which is the beginning of pregnancy.

Treating blocked fallopian tubes[change | change source]

If a patient's fallopian tubes are blocked by a small amount of scar tissue or adhesions, your Doctors use laparoscopic surgery (keyhole surgery) for removing the blockage and opening the tubes.[5]

If your fallopian tubes are blocked by a large amount of scar tissue or adhesions, treatment may not be possible to clear the blockages.[6]

Surgery may be an option to repair tubes damaged by an ectopic pregnancy or infection. If the blockage occurs because part of the fallopian tube is damaged, a doctor can remove the damaged part and connect the two healthy parts.
