Final answer:
Fertilization is not usually associated with the uterus. It typically occurs in the fallopian tubes.
Step-by-step explanation:
The function that is not usually associated with the uterus is fertilization. Fertilization of the egg by the sperm typically occurs in the fallopian tubes, not in the uterus. The uterus is responsible for gestating a fetus if fertilization occurs, supporting the development of the embryo or fetus during pregnancy.
