Quick Summary

Embryo transfer is a procedure used in both human and animal reproduction. In humans, it is the final step of in vitro fertilization (IVF), where one or more embryos are transferred into the uterus, typically via a catheter through the cervix. This follows the fertilization of an egg by sperm outside the body.12

In animal breeding, embryo transfer involves removing an embryo from a superovulated female and implanting it into the uterus of another female. This technique allows for the rapid spread of desirable genetic traits. Ethical considerations surrounding IVF, particularly concerning the creation, use, and potential destruction of embryos, are also a significant aspect of the discussion.134

cryopreservation
In the process of frozen embryo transfer, the embryos are thawed and implanted into the woman’s uterus. Frozen embryo transfer is associated with a small but significant increase in the risk of childhood cancer among children born from such embryos.
