Human Menstrual Cycle Hormonal Overview
Diagram showing hormonal changes during the "typical" human menstrual cycle.

Legend |
Features
- Cycle days are numbered (-14 to +14) with respect to peak (0) of mid-cycle leutenizing hormone surge.
- Cycle days are often numbered (1 to 28) from the first day (1) of menses.
- Gonadotrophin releasing hormone (GnRH) is released from about 1000 neurons within the hypothalamus in a pulsatile manner.
- Leutenizing hormone (LH) increases mid-cycle driving ovulation.
- Ovulation occurs during this mid-cycle LH surge.
- Not shown are the Inhibin A and Inhibin B levels.
- New figure version is more accurate for body temperature and estrogen changes.
- Even more smoothed hormonal curves are often shown in simplified diagrams.
- Links: menstrual cycle | ovary | uterus | hypothalamus | pituitary | Week 1 | Week 2
