Organs and structures of the male and female reproductive systems.
In the human female reproductive tract, fertilization usually occurs within the fallopian tube, specifically in the section known as the ampulla.12
The ampulla is the expanded, thin-walled intermediate portion of the tube. During the process, sperm cells travel through the vagina and uterus to reach the egg in the fallopian tube. Once fertilization takes place, the resulting zygote is transported toward the uterine cavity, a journey that typically takes about three to four days.213
