Research Progress on Luteinizing Hormone and Polycystic Ovary Syndrome

Abstract

Polycystic ovary syndrome is a common endocrine disease in women of childbearing age, with an incidence of about 6% to 10%, which is the main cause of anovulatory infertility. With the development of assisted reproductive technology, up to 60% of patients with polycystic ovary syndrome need to be pregnant successfully through in vitro fertilization and embryo transfer. Ovarian controlled ovulation induction is an important process in assisted reproductive therapy. Luteinizing hormone plays an important role in the development and maturation of follicles in the ovary, and high levels of luteinizing hormone have a negative effect on pregnancy outcome. at present, it is still controversial that the appropriate level of luteinizing hormone will improve the pregnancy outcome, and the mechanism of how luteinizing hormone affects the pregnancy outcome is still unclear. This article will mainly review the above two aspects in order to provide reference for clinical research in the future.
