Title:
BIOMARKER FOR DETERMINING FERTILITY, AND DETERMINING METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/149410
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a biomarker by which embryos having a high implantation/pregnancy probability, i.e., having high fertility can be selected from among embryos obtained by in vitro fertilization and then embryo culturing in infertility treatment; and a determination criterion thereof. The present invention provides a criterion with which an egg suitable for implantation/pregnancy can be determined, by measuring the concentration of soluble CD163 present in a follicular fluid to be collected simultaneously with the egg at the time of egg collection in infertility treatment or in a serum immediately before the egg collection.
