A comparison of DC-SIGN reactivity with the interaction of plant lectins that distinguish both glycoepitopes allows us to suggest that in the studied material, the content of high-mannose oligosaccharides is a feature able to distinguish natural interactions among patients with different reproductive potential, as shown in scatter plots (Figure 5), in which a tendency to form separate clusters are observed for patients with idiopathic normozoospermia and those with infertility related to abnormal semen parameters. This evidence concerns the gene CD209 and Infertility.
