Embryo culture, also known as in vitro embryo culture, is a technique commonly used in animal and human reproduction. It is used to facilitate the development of embryos grown in an artificial environment outside the body.

The process of embryo culture begins with the collection of an ovum from the female reproductive tract, which is then fertilized with sperm in an in vitro environment, such as a Petri dish. The fertilized egg is then incubated in a special culture medium for a period of time. During this time, the embryo divides and grows until it reaches the blastocyst stage, which is the stage at which an embryo is ready for implantation.

Embryo culture is a critical step in the process of assisted reproductive technology (ART), a technique used to help couples conceive a child. The technique is used in cases of infertility, congenital diseases, and to help increase the chances of successful pregnancy.

Embryo culture can also be used to select embryos with the desired genotype. This technique is known as preimplantation genetic diagnosis (PGD). It involves testing embryos for genetic diseases, chromosomal abnormalities, and other conditions that could affect the health of a child. PGD can also identify embryos with a desired sex.

Embryo culture is a complex and delicate process, and it should be carried out under the supervision of a reproductive specialist. The specialist will determine the best culture medium for the embryo, and the most suitable incubation conditions for its development.
