Blastocyst score affects implantation and pregnancy outcome: towards a single blastocyst transfer
TL;DR: The ability to transfer one high-scoring blastocyst should lead to pregnancy rates greater than 60%, without the complication of twins, according to a retrospective review of blastocysts transfer in an IVF clinic.

A prospective randomized trial of blastocyst culture and transfer in in-vitro fertilization.
TL;DR: The ability to transfer just two blastocysts while maintaining high pregnancy rates will help to eliminate high order multiple gestations and improve the overall efficiency of human IVF.
The relationship between blastocyst morphology, chromosomal abnormality, and embryo gender
Samer Alfarawati,Elpida Fragouli,Pere Colls,John Stevens,C. Gutiérrez-Mateo,William B. Schoolcraft,Mandy G. Katz-Jaffe,Dagan Wells +7 more
TL;DR: Morphology and aneuploidy are linked at the blastocyst stage, however, the association is weak, and consequently, morphologic analysis cannot be relied on to ensure transfer of chromosomally normal embryos.

Noninvasive assessment of human embryo nutrient consumption as a measure of developmental potential.
TL;DR: The ability to identify in culture the embryo with the highest developmental potential will facilitate the move to single-embryo transfers and be of use in identifying blastocysts for transfer.

Improved controlled ovarian hyperstimulation in poor responder in vitro fertilization patients with a microdose follicle-stimulating hormone flare, growth hormone protocol
TL;DR: The microdose GnRH-a, FSH, GH protocol is superior to standard protocols for the treatment of patients with decreased ovarian reserve undergoing controlled ovarian hyperstimulation for IVF.
