It is clear that the longer the ring finger compared to the index finger, the larger the penis tends to be

Studies have shown that the length of a male penis can be determined by looking at the index and ring fingers.

According to a report in the Asian Journal of Andrology, a magazine on male epidemiology, the smaller the '2D: 4D ratio', which is the ratio of the index finger to the ring finger, that is, the longer the ring finger is to the index finger, the larger the penis tends to be. The research result that is seen is announced.

The view that the ratio of male index finger to ring finger length is related to hormone contact is not new, and looking at that ratio has caused 'sperm count' and 'heart attack'. Research results have been published that show 'potential', 'dominant hand', ' masculinity of the face' and so on.

The experiment was conducted at Gachon University in South Korea. After anesthetizing subjects in 144 men in their 20s who were scheduled to undergo urological surgery, researchers found their finger lengths and the length of their penis in a contracted and stretched state. Measure. The length in the stretched state was treated as the length at the time of erection in the data.

The average length of the penis in the shrunk state was 7.7 cm, and it varied from 4 cm to 12 cm depending on the person. The average length of the stretched penis at the time of erection was 11.7 cm, and the numbers varied from 7.5 cm to 17 cm.

The average ratio of index finger to ring finger (index finger length ÷ ring finger length) was 0.97, and the bottom was from 0.88 to 1.12. Researchers believe that the smaller this number, the longer the penis tends to be. In the original text, the ratio has a unit of length for some reason, but what this number represents is the so-called '2D: 4D' ratio.

Researchers find this view useful in treating androgen-related illnesses such as prostate cancer, as the proportion of fingers can be used to estimate the amount of androgen that the person was exposed to in the womb when he was a foetation. I'm wondering if it is.
