Hormones and Orientation
How can hormones account for sexual orientation?
Hormones are thought to play a role in shaping sexual orientation by influencing brain development and wiring in ways that affect sexual attraction and behavior. Here are some of the main ways hormones might contribute to sexual orientation:
1. Prenatal Hormonal Exposure
- During critical periods of fetal development, exposure to sex hormones (primarily androgens like testosterone) can affect brain structures involved in sexual attraction and orientation. For example, higher prenatal androgen levels are linked with brain patterns associated with male-typical attraction patterns, while lower levels are linked with female-typical attraction patterns.
- Research suggests that variations in prenatal hormone exposure may contribute to a spectrum of orientations, as hormone levels and sensitivities vary, resulting in differences in how certain brain regions are structured and wired.
2. Hormone Sensitivity and Receptor Variability
- Some individuals may have genetic variations that alter their sensitivity to hormones like testosterone or estrogen. These variations may lead to differences in how brain areas related to sexual preference develop, potentially influencing orientation…
