This podcast discusses how exposure to androgens in utero has an impact on sexual development, including sexual preference and mate choice.
The study conducted by a researcher in the auditory system found that females who self-report as lesbians have significantly more autoacoustic emissions than those who don't self-report as lesbians, in addition, there were finger length ratio studies on males and females who self-reported as homosexual or heterosexual.
The length ratio between the index finger and ring finger is a potential indication of prenatal exposure to androgens. Studies conducted on mice and humans have shown that greater exposure to androgens results in a smaller D4-D2 ratio, meaning a longer ring finger than index finger.
Hormones have both early and long-term effects on the brain and behavior, including the potential to influence same or opposite sex partner choice in adulthood. It is important to consider all aspects of sex and the effects of hormones on the body and brain when discussing this topic.
