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.

Assessing aggregate exposure to a series of compounds with the same biological mechanism is called cumulative exposure assessment.
<h3>
What is cumulative exposure?</h3>
Because cumulative exposure evaluations evaluate exposure to numerous stressors via different pathways, they are referred to as "combined exposure assessments." Exposures to a single stressor are estimated using aggregate evaluations from different sources and pathways.
Cumulative evaluations portray real-world exposure more accurately, but they also provide an element of complexity not seen in typical exposure assessments , which evaluate stressors separately.
