Detailed Description

Ovarian reserve function and endometrial receptivity are important components of female fertility. Ovarian function is regulated by various factors, including genetics, environment, oxidative stress, inflammatory response, and endocrine regulation. Decline in ovarian function is an important factor leading to decreased fertility and perimenopausal symptoms. Endometrial receptivity refers to the ability of the endometrium to accept embryos, that is, the ability to allow the embryo to undergo processes such as positioning, adhesion, and invasion in the uterine cavity. Endometrial receptivity is a key factor for successful embryo implantation.

Royal jelly, as a natural biological nutrient, is rich in proteins, lipids, carbohydrates, vitamins, and various bioactive components. It shows various potential health benefits in promoting growth and development, regulating immune function, and antioxidation. The main active component of royal jelly - royal jelly major protein (MRJPs), has been proven to have significant effects in cell proliferation, anti-inflammatory, antioxidant, and endocrine regulation. Studies have shown that MRJPs can significantly increase serum estradiol and progesterone levels, reduce follicle-stimulating hormone and luteinizing hormone contents, increase the expression levels of estrogen receptor genes and progesterone receptor genes, increase the average thickness of the endometrium, thereby improving ovarian function and enhancing endometrial receptivity.

The ELELADY Royal Jelly Major Protein Rose Pressed Tablet Candy (Food Production License Number:SC10644070506130) has two major patent technologies. The specific detection patent technology can quickly detect the freshness of royal jelly to ensure the quality of raw materials, and the green ultrafiltration membrane separation patent technology can obtain high-purity freeze-dried powder of royal jelly major protein and bee royal jelly small molecule active essence liquid that can be stored at room temperature.

This study intends to adopt a scientific and rigorous experimental design, through the combination of clinical trials and basic experiments, strictly following ethical principles, to ensure the rights and safety of the subjects, and at the same time, adopt scientific data management and analysis methods to ensure the reliability of the research results. The conduct of this study will help reveal the potential application value of MRJPs in reproductive health, provide scientific basis for its application in regulating ovarian function and endometrial receptivity and the prevention and treatment of related diseases, and also provide new ideas and research directions for the development and application of natural products in reproductive medicine.
