When the Pattern (of Early Biomarkers) Matters: Evidence for Biodevelopmental Subgroups of Male Sexual Orientation

Sexual orientation is related to biodevelopmental factors. The present study employed the LPA using four markers—handedness, CGN, 2D:4D ratio, and FBO index—to distinguish sexual orientation subgroups of men. As some identified profiles differentiated the participants, our results suggest that sexual orientation is related to diverse biodevelopmental pathways.
