First Claim
Patent Images
1. A method for treating infertility in a female human subject, comprising:
- (A) providing one or more human embryos under in vitro culture conditions sufficient for embryo development;
(B) imaging said one or more human embryos for a time period from at least syngamy to at least a first cytokinesis to create images, wherein said one or more human embryos comprise at least one cellular parameter;
(C) identifying one or more abnormal syngamy (AS) embryos when said time period is less than 2.5 hours and one or more normal syngamy (NS) embryos when said time period is greater than 2.5 hours;
(D) deselecting said one or more human embryos when at least one of said images comprises said one or more AS embryos;
(E) selecting said one or more human embryos when at least one of said images comprises said one or more NS embryos; and
(F) developing at least one of said selected NS embryos under said in vitro culture conditions into a normal human blastocyst embryo; and
(G) treating infertility of a female human subject with said normal human blastocyst embryo by in vitro fertilization.

Abstract
Methods, compositions and kits for determining the developmental potential of one or more embryos are provided. These methods, compositions and kits find use in identifying embryos in vitro that are most useful in treating infertility in humans.
