Fingers to Tell Your Sex Orientation

Nowadays, it is hard to differentiate transvestite with normal people. But don't worry, biologist Zhengui Zheng at Howard Hughes Medical institute at Florida recently published an article that may uncover the relationship between finger growth and hormone level during embryonic development.

The study suggests that fingers are associated with hormone such as estrogen and testosterone. The study also will be continued with the link between finger length and health problem, aggression, musical talent and sexual orientation. 

For men, the ring finger is usually longer than their index finger and the opposite is true for women. This is because the prenatal hormonal environment can affect the digit proportions. For example, high testosterone level will affect the proportion of ring finger and high estrogen on the other hand affect the proportion of index finger. 

Typical women will tend to have their 2D to 4D either high or equal. 

Typical men will tend to have their 2D shorter than their 4D. 

**The picture is for illustration purposes only. It may not be true in all cases.

The study also lead to a point where outside events may leave a signature that can cause the hormonal imbalance and may link to diseases which can be diagnose at its early stage. Although the team only proved that 2D and 4D are affected by hormonal imbalance, we might aware of what this imbalance may cause especially in studying the behavioral trait.
