Human Menstrual Cycle Hormonal Overview

Diagram showing typical hormonal changes during the human menstrual cycle (even more smoothed versions are shown in simplified diagrams).

  • Ovulation occurs around the time of leutenizing hormone surge mid-cycle.
  • There is great variability in human menstrual cycle length.
  • There are cycle and hormonal age dependent changes.
  • Not shown are the Inhibin A and Inhibin B levels.

Legend

  • FSH - follicle stimulating hormone (from anterior pituitary)
  • GnRH - gonadotrophin releasing hormone (from hypothalamus also called LH-releasing hormone)
  • LH - leutenizing hormone (from anterior pituitary)
