Fertilization of the egg cell by the sperm usually takes place in the fallopian tube. The fertilized egg then travels to the uterus and implants in the endometrium.
<h3>What are fallopian tubes?</h3>
- Fallopian tubes are also called oviducts or uterine tubes. It is the passage through which the egg enters the uterine cavity from the ovary.
- Fallopian tubes are part of the reproductive tract. They have a smooth muscle wall, an inner mucous membrane, and an outer layer of loose supporting tissue (serosa).
<h3>Why does fertilization take place in the fallopian tubes?</h3>
The fallopian tube (oviduct) regulates fertilization through sperm induction and sperm hyperactivity. Sperm induction is achieved by rheotaxis, thermotaxis, and chemotaxis. Rheotaxis is caused by tubal fluid that creates a current flow from the tubal ampulla to the tubal isthmus.
