Which process does NOT occur in the uterus?

Fertilization does not occur in the uterus; instead, it takes place in the fallopian tubes. After sperm fertilizes an egg, the resulting zygote travels down the fallopian tube and into the uterus, where it can implant in the uterine lining. The uterus is essential for several critical processes involving pregnancy: fetal development occurs there once implantation takes place, and labor refers to the process of delivering the fetus through the uterus. Understanding this sequence is crucial for recognizing the role of different reproductive structures in human gestation.
