摘要
The invention provides a new method for evaluating transfer embryos including blastocysts used for in vitro fertilization in fertility treatment, and a method for evaluating transfer embryos using a new biomarker necessary for evaluation. The method comprises the steps of (a) providing a test object, for example, a culture solution of a human blastocyst, containing norepinephrine (noradrenaline) released from a transfer embryo, such as a human blastocyst, obtained from a subject; (b) quantitatively analyzing norepinephrine in the test object by a combination of ultra high performance liquid chromatography and mass spectrometry or the like; (c) predicting the quality of the transfer embryo based on the amount of norepinephrine from analysis results obtained; and (d) transferring the embryo into a suitable female recipient for implantation, if the transfer embryo is predicted to be of good quality and/or to lead to the establishment of a viable pregnancy based on step (c).
