In conclusion, represented by digit ratio (2D/4D) as a proxy marker, prenatal testosterone exposure may have a causal role in the sexual dimorphism observed in learning style preferences.
The serotonin precursor 5-hydroxy-l-[β-11C]tryptophan ([11C]HTP) is in clinical use for localization of neuroendocrine tumors and has been suggested as a proxy marker for pancreatic islet cells.

The ratio of the lengths of the second and fourth digits (2D∶4D) is a sexually differentiated trait believed by many to be fixed in utero, and thus, a possible proxy marker for prenatal androgen activity.
This would have allowed us to confirm that the findings were related to depression rather than being a peculiarity of the PGC, although this is mitigated by the fact that the PGC is a good proxy marker of depression [3], [4], [5], [6], [7], [8].
