10 body parts reveal penis size, by country! Research on the average man that'll really surprise you.

Is it possible for factors such as height, buttocks, nose, feet, fingers, and other body features to serve as indicators of penis size? Can one accurately estimate the length of a person's penis based solely on visual cues? In this video, I will explore 10 body parts or characteristics that are believed to have a potential correlation with penile length, examining the existing evidence across different countries and ethnicities.

Reasons Why You Cannot Take This As The Absolute Truth.

Before delving into the realm of art, it's crucial to acknowledge that the conclusions drawn from these research findings should not be taken as absolute truths. Firstly, we are discussing correlations on an average basis, implying that these findings may not hold true for every individual. 

Secondly, the quality of the research studies varies, impacting the reliability of the conclusions. Thirdly, there is significant variation in the ages of the subjects involved. Furthermore, what holds true for one country does not necessarily apply to another. 

It's important to note that the absence of mention regarding a specific country does not imply the truth or falsehood of these correlations for that country. It simply indicates either a lack of research or oversight on my part regarding available research for that particular region.

Characteristic #1. Height. 

Taller = longer penis?

First on the list is height. Is it accurate to say that taller individuals have longer penises? The answer is affirmative, but this correlation has been established through evidence gathered exclusively from men in four countries: Italy, Nigeria, Iran, and Turkey. 

In an extensive study involving 3,300 men in Italy, as well as a study with 271 participants in Nigeria, and a study conducted in Iran, researchers concluded that indeed, taller men tend to have longer penises. However, in the case of the Turkish study, the correlation is observed to be weak. 

It's worth noting that this association may not hold true for individuals from India, as conflicting studies exist for this region. Therefore, we can confidently assert a positive correlation for Italy, Nigeria, and Iran, a weak positive correlation for Turkey, and a tentative stance for India.

Characteristic #2. Nose size. 

Bigger nose = bigger penis?

Moving on to the second characteristic: nose size. Does having a larger nose imply a larger penis? The answer is affirmative, but this correlation has been established only for individuals from Japan and South Korea. In studies conducted in Japan and South Korea, researchers identified a significant correlation between nose size and penile length. 

However, it's essential to note that there is no research on nose size from other countries. Therefore, it would be inaccurate to generalize that all men with large noses, who are not Japanese or Korean, also have larger penises. Consequently, we can only affirm this correlation for Japan and South Korea.

Characteristic #3. 2nd finger to 4th finger length ratio. 

Low 2D:4D ratio = longer penis?

Let's explore characteristic number three, the second finger to fourth finger length ratio, and its potential correlation with penis size. This ratio is particularly intriguing as it appears to predict penis length across various countries, as indicated by this study. According to the findings, individuals with a lower 2D to 4D ratio tend to have a longer penis.

To calculate the 2D to 4D ratio, you measure the length of the second finger (index finger) from the crease to the tip and do the same for the fourth finger (ring finger). The ratio is then determined by dividing the length of the second finger by that of the fourth finger. 

The study proposes that a lower 2D to 4D ratio in men is associated with increased testosterone exposure during fetal development, leading to the elongation of both the fourth finger and the penis.

This phenomenon is observable in females as well. The study notes that females with congenital adrenal hyperplasia, a condition where exposure to high levels of male hormones occurred during fetal development, also exhibit a lower 2D to 4D ratio compared to normal females.

What adds further intrigue is the observation that different ethnicities demonstrate distinct 2D to 4D ratios correlating with penis length. 

The study, involving 798 boys from various ethnic backgrounds, including 90 Caucasian Berbers, 438 Wegers, 118 Han Chinese, and 152 African Jamaicans, reveals that African Jamaicans exhibit the lowest 2D to 4D ratio, followed by Caucasian Berbers and Wegers, then by Han Chinese. 

In simpler terms, African Jamaicans, with the lowest 2D to 4D ratio, are indicated to have the longest penises. Thus, we can confidently assert a positive correlation for these specific ethnicities.

Characteristic #4. Index finger length. 

Long index finger = longer penis?

Moving on to characteristic number four, does the length of the second finger (index finger) alone predict penis length? It appears that this might be the case, particularly for men from Iran and Egypt, as indicated by findings from an Iranian study and an Egyptian study. 

Therefore, we can affirmatively attribute a positive correlation between index finger length and penis length for individuals from Iran and Egypt.

Characteristic #5. BMI. 

Bigger BMI = longer penis?

Now, let's consider characteristic number five, the Body Mass Index (BMI), and its role as a predictor of penile length. The BMI is calculated as follows: [BMI formula]. Notably, BMI correlates with penile length, but this association is observed only in men from Iran and Egypt, as evidenced by findings from an Iranian study and an Egyptian study. 

It's crucial to emphasize that BMI does not show a correlation with penile length in studies conducted in Nigeria, India, Turkey, and South Korea, as demonstrated by research from these respective countries. Therefore, we can affirm a positive correlation for Iran and Egypt but not for Nigeria, Turkey, India, and South Korea.

Characteristic #6. Weight. 

Bigger weight = longer penis?

Let's explore characteristic number six, which pertains to weight as a predictor for penile length. In general, most studies do not indicate a correlation between weight and penile length. For instance, findings from studies conducted in Iran and India fail to show such a correlation. 

However, there is research from Italy, as demonstrated by an Italian study, and also from Turkey, albeit with a weak affirmative result. Therefore, we can conclude that there is no correlation for Iran and India, but there is a positive correlation for Italy and a weak positive correlation for Turkey.

Characteristic #7. Anus to Scrotum distance. 

Long AGD = longer penis?

Exploring characteristic number seven, we turn our attention to the Anus-to-Scrotum Distance (AGD), which is the distance from the center of the anus to the beginning of the scrotum. 

Notably, research indicates a strong correlation between AGD and penile length, suggesting that a longer AGD corresponds to a longer penis. According to this review, the positive impact of male hormones during fetal development is likely responsible for this correlation.

Studies conducted in various countries further support this correlation between AGD and penile length, as evidenced by research from Nigeria, Turkey, Iran, and Egypt. 

It's important to note, however, that these studies primarily involve infants and toddlers, and the applicability of these findings to adult men remains uncertain. Therefore, we cautiously acknowledge a positive correlation between AGD and penile length for Nigeria, Turkey, Iran, and Egypt.

Characteristic #8. Testicular size. 

Bigger testicles = longer penis?

Now, turning to characteristic number eight, let's consider testicular size as a potential correlator of penis size. It intuitively follows that a longer penis might be associated with larger testicles. 

This correlation is supported by findings from Indian studies on infants, where it was observed that the longer the penis, the larger the testicles. Additionally, a Turkish study suggests a weak positive correlation for men around 20 years old, indicating a trend in this age group.

Moreover, a South Korean study adds another dimension by suggesting that, for adult South Korean men, larger testicles are associated with a thicker penis. 

Consequently, we can confidently affirm a positive correlation for India and South Korea, a weak positive correlation for Turkey, and a positive correlation for penis thickness in South Korea.

Characteristic #9. Foot length. 

Bigger feet = longer penis?

Moving on to characteristic number nine, let's explore the correlation between foot length and penis size. The answer to whether having big feet corresponds to a larger penis depends on the geographical context. If you're from India, the answer is affirmative, at least for Indian babies, according to findings from an Indian study. 

However, if you're from the UK, the answer is negative, as indicated by research conducted in the UK. Therefore, we can affirm a positive correlation for foot length in India but a negative correlation for the UK.

Characteristic #10. Butt size. 

Bigger butt = longer penis?

Let's delve into characteristic number 10, which revolves around butt size and its potential correlation with penis size. The answer to whether a larger buttocks corresponds to a bigger penis is affirmative, but intriguingly, this correlation has been established only in Nigeria, as evidenced by findings from a Nigerian study. Consequently, we can confidently assert a positive correlation solely for Nigeria.

It's fascinating to observe how various body parts or characteristics demonstrate correlations with penile length. As we've witnessed, what holds true for one country may not necessarily apply to another.
