Application of follicular fluid exosome in preparation of product for treating fertility decline of elderly women

The invention belongs to the technical field of biological medicines, and particularly relates to application of follicular fluid exosomes in preparation of products for treating fertility decline of elderly women. The invention provides an application of a follicular fluid-derived exosome in preparation of a product for treating fertility decline of elderly women. According to the method, firstly, human follicular fluid is obtained, then the exosome of the human follicular fluid is extracted, and then the follicular fluid exosome is used for treating fertility decline caused by the elderly. Experimental results show that the follicular fluid exosome is beneficial to improvement of oocyte quality and promotion of follicular maturation. The method for treating fertility decline by means of the follicular fluid exosome has the advantages that the exosome is derived from the follicular fluid in the environment of the exosome, the exerted biological effect is closer to a natural result, and high safety is achieve
