Comparison of the matched pairs of fertile and non-fertile samples for the 15 cycles, using Total Odour, Richness, Shannon’s H, Simpson’s D, and MDS1 and MDS2. Each line represents a cycle and the colours represent the different females. Only Total Odour shows a clear difference between non-fertile and fertile samples. Greater clustering of lines by individual (colour) indicates lower variability in the odour profile of each female.
