LH/FSH has a greater clinical significance in patients with polycystic ovary syndrome. Such patients have a relatively high level of androgens and an imbalance in the ratio of follicle-stimulating hormone to luteinizing hormone due to an endocrine disorder in the body, which leads to ovarian hyperplasia and many tiny follicles. Such patients will have LH/FSH >3 and most patients with polycystic ovary syndrome will have such a ratio, which is also a marker for the diagnosis of this disease. Therefore, if a patient presents with an increased ratio and has scanty menstruation, as well as androgenic symptoms, such as hirsutism and acne, polycystic ovary syndrome should be considered and further ultrasound examination is needed.
