In vitro fertilization (IVF) is a popular assisted reproductive technology that helps couples conceive by fertilizing eggs with sperm outside the body. There are several synonyms for IVF that are commonly used to describe this process, including "test tube baby," "assisted reproduction," "infertility treatment," and "artificial insemination." Other terms used in this area of reproductive medicine include "embryo transfer," "cryopreservation," and "intracytoplasmic sperm injection" (ICSI). Regardless of the term used, IVF has helped millions of couples overcome infertility and realize their dream of starting a family.
