In Vitro Fertilization (IVF): Definition and Meaning

    Definition and Pronunciation

    In vitrofertilization (IVF) is an assisted reproductive technology (ART) in which a sperm fertilizes an egg outside the body in a laboratory. After fertilization, one or more embryos may be transferred to the uterus in an attempt to achieve pregnancy.

    Pronunciation: in VEE-troh fur-tuh-luh-ZAY-shuhn (IVF: eye-vee-EFF)

    Easy Explanation

    In vitro fertilization (IVF) is a fertility treatment that helps people conceive a child when natural conception is difficult or unsuccessful. During IVF, doctors collect mature eggs from the ovaries and combine them with sperm in a laboratory. If fertilization occurs, the resulting embryo is monitored for several days before being transferred to the uterus.

    IVF may be recommended for certain causes of infertility, such as blocked fallopian tubes, ovulation disorders, reduced sperm quality, unexplained infertility, or when donor eggs, donor sperm, or a gestational carrier is used.

    Word Comparisons

    In Vitro Fertilization vs. Natural Fertilization
    In natural fertilization, the sperm fertilizes the egg inside the fallopian tube. In IVF, fertilization occurs outside the body in a laboratory before the embryo is transferred to the uterus.

    In Vitro Fertilization vs. Artificial Insemination (IUI)
    In intrauterine insemination (IUI), sperm is placed directly into the uterus, and fertilization occurs naturally inside the body. In IVF, fertilization takes place in the laboratory.

    In Vitro Fertilization vs. In Vivo Fertilization
    In vitro fertilization occurs outside the body, whereas in vivo fertilization occurs naturally inside the reproductive tract.

    In Vitro Fertilization vs. Intracytoplasmic Sperm Injection (ICSI)
    IVF allows sperm and egg to fertilize naturally in a laboratory dish. ICSI is a specialized IVF technique in which a single sperm is injected directly into an egg to assist fertilization.

    Connotations

    The term in vitro fertilization has a neutral and medical meaning. It is widely used in reproductive medicine, obstetrics, gynecology, embryology, and fertility care.

    For many individuals and couples, IVF represents hope for achieving pregnancy when natural conception is not possible or has not been successful.

    Connection to Sexuality

    In vitro fertilization is closely connected to humanreproduction but differs from natural conception because fertilization occurs outside the body. IVF provides an option for people who experience infertility or who need medical assistance to achieve pregnancy.

    Although IVF is a reproductive technology, sexuality extends beyond reproduction. Human sexuality also includes sexual orientation, gender identity, attraction, intimacy, relationships, and sexual well-being. Understanding IVF helps explain one of the most important advances in modern reproductive medicine and family-building.
