Conception (fertilization) usually occurs in the fallopian tube , most often in the wider part called the ampulla, which lies between the ovary and the uterus.

Quick Scoop: What Actually Happens

  • During ovulation, an ovary releases an egg, which is swept into the nearby fallopian tube.
  • Sperm travel through the vagina, cervix, and uterus to reach the fallopian tube.
  • When one sperm successfully fuses with the egg in the tube, conception has occurred.
  • The resulting embryo then travels down into the uterus over several days and implants in the uterine lining, which is when pregnancy really “settles in.”

Very rarely, fertilization can happen closer to the uterus or an embryo can implant outside the uterus (like in an ectopic pregnancy), but under normal conditions conception is a fallopian‑tube event.
