How do I identify the hormones when they are displayed on a graph of the mentsrual cycle?

It is important to look at the shape of each line.  Regardless of the species, the line with the largest, solitary spike is LH (luteinising hormone) and this occurs just before ovulation.  The line which is has a small rise at the beginning and then a small peak at the same time as LH is FSH (follicle-stimulating hormone).  Progesterone is high after the spike of LH and falls before menstruation.  Finally, oestrogen has two peaks, one before the spike of LH, and then it rises again while progesterone levels are high.

Basically, once you have identified LH - the others fall into place!
