In vitro fertilization (IVF), colloquially called “artificial insemination”, involves many different steps. In addition to hormonal stimulation, these include minor surgical procedures. This kind of artificial insemination does not actually begin in the uterus of a woman; instead it happens in a test tube in a medical clinic or laboratory. The treatment often extends over several weeks.
With IVF, women’s hormone treatment is almost always necessary. The doctor then removes eggs from the ovary and brings them together in a laboratory glass with the partner’s sperm. If the fertilization is successful and the fertilized eggs continue to develop, one to a maximum of three embryos is transferred to the uterus.
