Endometrial research is focused on studying the endometrium, which is the inner lining of the uterus. This area of research examines the functions, structure, and health of the endometrium, as well as its role in the menstrual cycle, pregnancy, and various gynecological conditions such as endometriosis, adenomyosis, and endometrial cancer. Researchers in this field investigate the molecular, cellular, and hormonal mechanisms underlying endometrial changes and how they can impact reproductive outcomes and women's health. Understanding endometrial biology is crucial for the development of new diagnostic tools, treatments, and prevention strategies for endometrial-related disorders.
