発明の名称 (英語) BIOMARKER FOR TESTING POSSIBILITY OF FERTILIZATION OF OVUM AND DETERMINATION USING SAME
発明の概要(英語) Provided is a novel biomarker for testing the possibility of fertilization of an ovum. The method for testing the possibility of fertilization of an ovum in a subject is characterized by comprising measuring the amount of one or more peptides selected from the peptides of the amino acid sequences represented by SEQ ID NOS:1 to 4 in a follicular fluid that is collected from the subject.
従来技術、競合技術の概要(英語) BACKGROUND ART
Next in Japan is declining birthrate elderly, prenatal human 1 human 50, about 2 million per year is worn by the child and in-vitro fertilization, declining birthrate and aging of the pawl in-vitro fertilization is essential to the medical personnel in recent years as it has been widely used. On the other hand, the success rate of in-vitro fertilization, such as fertility, depending on the state of the egg protein or collecting However, the quality or state suitable for fertilization ovae is currently no method to determine.
Conventionally, after the processing of in-vitro fertilization of the ovum by the microscopic observation of the physician was a selection method, in this case, depending on the experience of the surgeons, together with the entering subjective judgment, determination takes a long time.
According to a recent study, in accordance with a change in the quality of ova in the elderly, illnesses that pregnancy, childbirth and the high risk factor. At the time of in-vitro fertilization when harvesting ovae obtained at the same time from a component of follicular fluid, such as fertility attempting to determine the quality of ova attempts have been made (Patent Document 1 and Non-Patent Document 1), can be examined quickly with high precision suitable biomarker has not been discovered until now.
In-vitro fertilization in the future to further increase the ratio of the old child is predicted from, the success rate of fertilization and a problem of increase of the urgent. Ovae high fertility or selection method of determining a developed which, leads to an improvement of the success rate of in-vitro fertilization, and is coupled to the desired good news for a child, the progress in the future are expected to be applied to the declining birthrate than Japan pawls elderly that may be one of the means of the expected.
