FIELD: medicine.
SUBSTANCE: invention is intended to predict endometrial receptivity based on the evaluation of GnRG and GnRGR expression in the "implantation window" in the endometrium of women with infertility and failure attempts of IVF programs. Prognostically unfavorable indicators of endometrial receptivity include a delay in the secretory transformation of the endometrium, a decrease in the number of cells containing mature pinopodia in the superficial epithelium of less than 20%, and low GnRG and GnRGR expression (<2 points).
EFFECT: method increases the accuracy of pregnancy prediction in IVF programs and natural cycles for women with infertility.
