Inhibin B is a peptide hormone produced by the granulosa cells of the ovaries (in females) and Sertoli cells (in males). In an Ovarian Cancer Panel, it serves as a specific tumor marker for mucinous and granulosa cell tumors. Beyond oncology, it is a primary marker for ovarian reserve and function, as its levels reflect the number and health of developing follicles.

Why Context Matters
In premenopausal women, Inhibin B levels fluctuate significantly with the menstrual cycle (peaking in the early to mid-follicular phase). A single 'low' reading without knowing the cycle day can be easily misinterpreted. Additionally, it may be elevated in Polycystic Ovary Syndrome (PCOS).
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
