Where does female zygote formation occur?
Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote. From here, the zygote will move down the fallopian tube and into the uterus. The zygote then burrows into the uterus lining.
Where is the zygote implanted in the female reproductive system?
Answer. Fertilization of an egg by a sperm normally occurs in the fallopian tubes. The fertilized egg then moves to the uterus, where it implants to the uterine lining.
Where is zygote formed?

In which structure of the female reproductive system does fertilization occur?
