Changes in Serum, Follicular Fluid SREBP1c and LRG1 Levels in PCOS Patients and Correlation With Insulin Resistance

Polycystic ovary syndrome (PCOS) is a common reproductive endocrine and metabolic disease that affects 6-20% of women of childbearing age worldwide. Due to changes in modern lifestyles such as low fiber, high fat diets, sedentary lifestyles, smoking, and alcohol consumption, the risk of developing this disease has increased. Its clinical manifestations are heterogeneous, with typical clinical manifestations being oligomenorrhea or amenorrhea, infertility, hirsutism, and polycystic ovarian changes under ultrasound. Women affected by PCOS face significant reproductive challenges, seriously affecting their quality of life and increasing their psychological burden.LRG1 has various regulatory functions, including glucose and lipid metabolism, IR, angiogenesis, organ fibrosis, and inflammation. LRG1 can activate the transcription factor SREBP1 and participate in liver lipid synthesis in obese mice. SREBP1c is the active form of SREBP1. Research has shown that SREBP1c can directly or indirectly participate in the development of IR. Therefore, the investigators speculate that LRG1 may play a certain role in the progression of PCOS through SREBP1c.Understanding the local changes or metabolic characteristics of follicular fluid in patients with PCOS can help elucidate the pathogenesis of PCOS. Therefore, in this study,the investigators aim to detect changes in serum and follicular fluid LRG1, SREBP1c, and related hormone levels, and explore their role in the pathogenesis of PCOS from a systemic and ovarian perspective, providing new ideas for the prevention and treatment of PCOS and IR.
