A method in which a woman's egg is fertilized outside the body, then implanted in one of her fallopian pipes. This method is one of the methods used to overcome infertility, the inability of combines to produce offspring on their own.
First, the egg and the male sperm desired to fertilize it are harvested. Then the egg and the sperm are joint in a petri dish, a multi-purpose cut-glass or plastic container with a lid. If all goes well, the sperm inseminates the egg, and the physicians then implant it in a fallopian tube. From there, nature receipts its course, and the egg eventually is put by the fallopian tube into the uterus (womb) for development.
A zygote is the joint cell resulting from the union of semen and egg. A zygote develops into an embryo. An embryo, a mass of cells with no familiar human features, begins development of a human body. After around seven or eight weeks, the embryo exhibits familiar features such as a mouth and ears. At this stage, the emerging human becomes recognized as a fetus. The word "zygote" is resulting from the Greek word "zygon" (yoke).
