* GOAL: To hyperstimulate [[Ovary - Anatomy & Physiology|ovaries]] with gonadotrophins.
* GOAL: To hyperstimulate [[Ovary - Anatomy & Physiology|ovaries]] with gonadotrophins.
* REASON: To provide higher than normal numbers of [[The_Ovary_-_Follicles_- Anatomy & Physiology|follicles]] that reach dominance and [[The_Ovary_-_Ovulation_- Anatomy & Physiology|ovulate]].
* REASON: To provide higher than normal numbers of [[Follicles - Anatomy & Physiology|follicles]] that reach dominance and [[Ovulation - Anatomy & Physiology|ovulate]].
* 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 & Physiology|fertilisation]] rates and genetic combinations possible.
* GOAL: Inseminate donor with semen from genetically superior bulls. To generate the best [[Fertilisation - Anatomy & Physiology|fertilisation]] rates and genetic combinations possible.
* REASON: Enhance rate of genetic progress.
* REASON: Enhance rate of genetic progress.
* HOW: Use highly fertile semen and well-trained, experienced inseminators.
* HOW: Use highly fertile semen and well-trained, experienced inseminators.
* REASON: To achieve pregnancy in each recipient.
* REASON: To achieve pregnancy in each recipient.
* HOW:
* HOW:
** Both donor and recipient have a [[The_Ovary_-Corpus_Luteum_- Anatomy & Physiology|corpus luteum]] at similar stages of leutinization.
** Both donor and recipient have a [[Corpus Luteum - Anatomy & Physiology|corpus luteum]] at similar stages of leutinization.
** [[Uterus - Anatomy & Physiology|Uterine environment]] in the donor and recipient are quite similar.
** [[Uterus - Anatomy & Physiology|Uterine environment]] in the donor and recipient are quite similar.
** A single embryo is placed into the uterine horn using a transfer pipette.
