Polycystic ovary syndrome (PCOS) is a neuroendocrine disease with complex etiology characterized by infrequent menstruation, follicular developmental disorders, insulin resistance, and hyperandrogenism. PCOS patients often suffer from anovulatory infertility, and even after successful pregnancy promotion, spontaneous abortion is easy to occur. At present, PCOS is mainly diagnosed by auxiliary examinations such as sex hormones and B ultrasonography, and there is a lack of specific serological markers for the diagnosis of diseases. Similarly, there is a lack of effective evaluation methods for the risk of abortion in PCOS patients. Therefore, it is extremely important to explore the factors that affect the occurrence of abortion in PCOS patients and to find specific indicators that can guide the pregnancy outcome of PCOS patients. The purpose of this study was to investigate the serum levels of platelet-derived growth factor (PDGF), epidermal growth factor (EGF), and soluble fms-like tyrosine kinase-1 (sFlt-1) in PCOS patients and analyze their predictive effects on the pregnancy outcomes of PCOS patients. The results showed that serum PDGF, EGF, and sFlt-1 levels were secreted abnormally in PCOS patients with abortion and were closely related to the pregnancy outcome of PCOS patients. The combination of the three levels has the highest value in predicting the pregnancy outcome of PCOS patients, which is worth promoting.
