Multiple ovulation and embryo transfer has been commercially available since the 1970s, but not widely used because it requires a highly skilled team.

* HOW: Treat recipient with a hormonal regime that induces oestrus to occur at the same time as the donor.

* HOW: Inject donor with gonadotrophins to hyperstimulate follicular development. Generally '''FSH''' or one of its analogs is used.

* GOAL: Inseminate donor with semen from genetically superior bulls. To generate the best [[Fertilisation%2C_Implantation_and_Early_Embryonic_Development_-Fertilisation-_Anatomy_%26_Physiology|fertilisation]] rates and genetic combinations possible.

** A flushing medium is then introduced into the [[Female_Reproductive_Tract_-The_Uterus_-_Anatomy_%26_Physiology|uterus]], lavaged and returned through the catheter to a collection vessel.
