The document discusses the role of anti-Müllerian hormone (AMH) in reproductive physiology and its significance as a biomarker for ovarian reserve, particularly in the context of assisted reproductive technologies like IVF. It highlights the variability in AMH measurement and its correlation with factors such as age, body mass index, and external influences like oral contraceptives and smoking. Additionally, it emphasizes the need for standardized AMH assays and age-specific reference values to improve clinical evaluations and treatments in fertility.
