1. Long fingers equals long penis?
Many people believe this statement, but it is only half true.
The saying that long fingers equal long penis does not refer to the length of fingers but the ratio of the length of the index finger and the ring finger.
A study published in the Asian Journal of Andrology in 2011 found that:
The ratio of the length of the index finger to the ring finger on the palm is closely related to the length of the penis. 144 men aged 20 or above participated in the statistics. According to the statistical prediction of the data model, the results showed that the ratio of the index finger to the ring finger is an important predictor of penis length.
In short, the lower the ratio of the index finger to the ring finger (that is, the shorter the index finger is than the ring finger), the longer the penis.
2. Big nose means strong sexual ability?
Because the shape of the nose is somewhat similar to the penis, the two are linked, but in fact, from a scientific point of view, there is no connection between the two.
3. Big Adam's apple means big penis?
Although boys with big Adam's apples look sexy at certain times, there is really no connection between the two.
Adam's apple, scientifically known as the anterior thyroid cartilage, is composed of two thyroid cartilages connected together.
Androgen levels are an important factor affecting the size of a boy's Adam's apple.
Scientific research has shown that men with small Adam's apples may have consumed androgen during their developmental period due to heavy physical training or frequent handicrafts.
4. The more hair, the stronger the desire?
Many people regard hair as a kind of masculinity. Because they believe that men with thick beards, leg hair, and chest hair have relatively strong androgen secretion in their bodies.
Androgen represents strength and bravery, and it is also believed that men with strong androgen have more complete development of secondary sexual characteristics, stronger desire, better sexual ability, etc.
But is it really so?
First of all, the amount of body hair depends not only on androgen levels, but also on genetics, hair follicle sensitivity, race and other factors.
Some people are born with hair follicles that are particularly sensitive to androgen. A little bit of hormone will make their hair grow wildly, while some people have sparse hair even if their testosterone levels are normal.
In other words:
More hair ≠ high testosterone, high testosterone ≠ strong sexual ability
5. The bigger the testicles, the stronger the sexual ability?
Although sexual ability is affected by male hormones, the level of male hormones and the size of the testicles are not completely proportional.
Feedback regulation, when the male hormones in the male body are too high, the gonad axis will inhibit the pituitary gland from secreting luteinizing hormone, thereby inhibiting the secretion of male hormones and maintaining balance.
So even if the testicles are larger than others, the level of male hormones in the body will not be much higher, which will not have much impact on sexual ability.
