* 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.

** 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.
