GENERAL HISTOLOGY

Detailed explanation-1: -Fertilization happens in your fallopian tubes when an egg and sperm meet. An active passageway that moves a fertilized egg to your uterus: A fertilized egg (embryo) travels through your fallopian tubes until it reaches your uterus, where it can grow into a fetus.

Detailed explanation-2: -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.

Detailed explanation-3: -Conception typically happens in your fallopian tubes. This is where an egg goes after it leaves your ovary and where sperm wait for an egg. In some cases, fertilization can happen in your uterus once your egg has left your fallopian tubes.

Detailed explanation-4: -Contact Between Sperm and Oocyte Upon ovulation, the oocyte released by the ovary is swept into-and along-the uterine tube. Fertilization must occur in the distal uterine tube because an unfertilized oocyte cannot survive the 72-hour journey to the uterus.

Detailed explanation-5: -An ectopic pregnancy occurs when a fertilized egg implants and grows outside the main cavity of the uterus. An ectopic pregnancy most often occurs in a fallopian tube, which carries eggs from the ovaries to the uterus. This type of ectopic pregnancy is called a tubal pregnancy.
