What is IVF?
In vitro fertilization (IVF) is an assisted reproductive technique in which an egg and sperm are combined outside the body to form an embryo that is then transferred into the uterus.
In Vitro Fertilization (IVF) is one of the most widely practiced forms of assisted reproductive technology (ART) worldwide. The procedure brings an oocyte and sperm together in a controlled laboratory environment, allowing fertilization to occur outside the human body before the resulting embryo is transferred into the uterus.
A standard IVF cycle usually involves five clinical stages: (1) controlled ovarian stimulation using gonadotropins to recruit multiple follicles; (2) ultrasound-guided transvaginal oocyte retrieval performed under sedation; (3) in vitro fertilization in the embryology laboratory, either by conventional insemination or by ICSI; (4) embryo culture for three to five days with continuous environmental monitoring; and (5) fresh or frozen embryo transfer, often supported by luteal-phase progesterone.
IVF is clinically indicated for tubal-factor infertility, severe male-factor infertility, advanced maternal age, endometriosis, unexplained infertility, and for patients requiring preimplantation genetic testing or fertility preservation. Treatment protocols, medication dosing and embryo selection strategies are individualized and must be evaluated and supervised by a licensed reproductive medicine institution operating within the regulatory framework of its jurisdiction.
As an industry cooperation body, WFA does not provide IVF services. Clinical care is delivered exclusively by WFA member institutions and other independent providers.
