ANATOMY

Detailed explanation-1: -Fertilization most often takes place in the ampulla. Isthmus: A tiny channel that connects the ampulla to the portion of your fallopian tube that’s closest to your uterus, the intramural portion. Intramural (interstitial) portion: The part of your fallopian tube that extends into the top of your uterus.

Detailed explanation-2: -Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.

Detailed explanation-3: -Ampulla. Fertilization occurs in the ampulla of the Fallopian tube, the section that curves around the ovary. Capacitated sperm are attracted to progesterone, which is secreted from the cumulus cells surrounding the oocyte.

Detailed explanation-4: -Sperm travels from isthmus to ampulla. Egg is collected by the fimbriae of the infundibulum. Egg is pushed by ciliated columnar epithelial cells to the ampullary region. Fertilisation takes place in the ampullary region of the fallopian tube.

Detailed explanation-5: -During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining-a process called implantation.
