Obesity is a global public health problem. According to literature reports, as of 2016, China's obese population has reached more than 90 million and type 2 diabetes mellitus has reached more than 100 million, which has brought a serious health and economic burden to China. In addition to various health problems such as cardiovascular, osteoarthritis, and tumors, obesity can also cause abnormalities in reproductive endocrine. In women, it can cause abnormal menstruation, polycystic ovary syndrome, and male obesity can cause secondary gonadal. Hypofunction (MOSH). MOSH is an endocrine dysfunction. It is reported to have a prevalence of approximately 45% in moderate to severe obesity. In addition, studies have pointed out that the prevalence of hypogonadism in men with type 2 diabetes and obesity higher.
