Related to embryo transfer: embryo implantation

em·bry·o trans·'fer

after in vitro artificial insemination, the embryo is transferred at the morula or blastocyst stage to the recipient's uterus or uterine tube.

embryo transfer

1. The process in which an egg that has been fertilized in vitro is transferred into a recipient's uterus.
2. A technique used in animal breeding in which an embryo from a superovulated female animal is transferred to the uterus of a recipient female animal. In both senses also called embryo transplant.

embryo transfer

a process of implanting a fertilized ovum in a uterus.


a new organism in the earliest stage of development, i.e. from the time that the fertilized embryo begins to develop a long axis up to the time that the major structures have begun to develop, when it becomes a fetus.

embryo collection
collection of an embryo from the genital tract for the purposes of embryo transfer; surgical and nonsurgical techniques available.
embryo cryopreservation
preservation of embryos by freezing.
hexacanth embryo
the larva with six hooks present in the cestode egg when it escapes from the uterus of the adult tapeworm. Called also oncosphere.
embryo micromanipulation
handling of an embryo under a microscope, for examination, dissection.
embryo transfer
collection of fertilized ova from one female before they become implanted and transfer to another female to complete the gestation. The donor is usually superovulated and then inseminated. Collection may be surgical via a laparotomy or nonsurgical by flushing through the cervix. Collected embryos must be stored carefully. They are evaluated in terms of fertilization, possibly cleaved artificially to create clones, and washed to eliminate the possibility of transferring infection with the embryo. Long-term storage by freezing is a practicable procedure. The recipient needs to be in appropriate stage of uterine receptivity, effected by synchronizing the estrus cycle with that of the donor.
embryo transplant
