Figure 3. Schematics showing the pathways from the SCN to HPG axis in female and male.

Figure 3

In females, direct projections from the SCN to GnRH, GnIH and Kiss1 cells, as well as a multi-synaptic pathway form the SCN to ovary have been identified (left panel). In males, it remains to be determined whether similar pathways from the SCN also exist.
