It does not contain DMSO. When being used for the cryopreservation of mouse oocytes and embryos, the solution may achieve the same or an even higher cell and tissue survival rate and functional expression stability as or than a commercial cryopreservation solution (containing 15% DMSO), and has high preservation efficiency. The cryopreservation solution without DMSO or serum reduces parasitic biological contaminants in the commercial cryopreservation solution containing serum currently used in clinical practice.

Abstract: A system and a method for assessing the ovarian reserve function of a subject. The system for assessing a subject's ovarian reserve function comprises: a data acquisition module configured to acquire data of the subject's age, anti-Müllerian hormone (AMH) level, follicle stimulating hormone (FSH) level, and antral follicle count (AFC); and an ovarian reserve function calculation module configured to calculate the above-mentioned information acquired in the data acquisition module, so as to work out the subject's probability of poor ovarian response (p). Further, the population is divided into four groups according to the interaction relationship between the predicted probability of poor ovarian response and the dose of ovulation stimulants, so as to divide the population with similar ovarian responses into one group.

Abstract: Disclosed in the present invention is a non-invasive detection method for screening for a well-developed blastocyst. A DNA methylation profile of a few of trophoblastic cells in a blastocyst is detected, and the average methylation level and the methylation pattern of embryos identified as having a good morphology in Gardner morphological blastocyst grading process are used as the standard for screening for well-developed blastocysts. The nearer the methylation level of the trophoblastic cells of the blastocyst to be tested approaches the methylation level or state of the good embryo, the better the embryo development is and the higher the suitability for being implanted into a maternal subject is. Furthermore, results of methylation sequencing may be analyzed to determine whether a chromosome is abnormal, so as to directly exclude chromosome-abnormal embryos.
