Abstract

Purpose

To provide a rationale for continuation of efforts to improve the outcome of Assisted Reproductive Technology outcomes, thereby increasing the likelihood of the live birth of healthy neonates.

Methods

Description of rationale and a framework leading to improvement in Assisted Reproductive Technology outcomes.

Results

The opportunity for improvement in the success rate for Assisted Reproductive Technology outcome is predicated on selection of the highest quality embryo(s) for transfer. However, such approaches must be balanced by a limit to the number of embryos transferred so as to reduce the risk for multiple births and particularly higher order multiple gestations. Blastocyst transfer offers one such successful approach, but is confounded by suggestions of an increased risk of both pregnancy complications and epigenetic disorders.

Conclusion

There is a need for development of approaches which, individually or in combination, may assist in the early detection of embryos destined to develop into blastocysts.

Capsule

A clinical need exist for establishment of approaches which can be utilized to assist in identification of embryos destined to develop into blastocysts.
