When it comes to penis size, it’s still a huge topic which can cause anxiety for men.
The NHS states the average UK penis size when “soft and gently stretched” is around 5.1in (13cm).
It also discovered that some manhoods were “growers”, while others were actually “showers”.
A lot of people might think penis size has a lot to do weight, height, hormones and BMI.
But it’s actually a lot simpler than you think, according to science it’s all to do with the mother’s genes.
Studies have found that the growth of the penis and limbs actually comes from the X chromosome.
Research conducted by Medical News Today found that penis size depends on a combination of the person’s parental genes.
Humans have 23 pairs of chromosomes and this determines their biological sex, as well as their secondary sexual characteristics.
Depending on the X and Y chromosome, this is why penis size might vary among siblings with the same biological parents.
Genetic mutations may also impact penis size and appearance, as well as other physical characteristics.
Of course there are other factors that affect size too, like hormones, environment and nutrition.
However, genetics are the strongest predictors of penis size, although factors like pubic hair and weight might impact their look.
There are numerous myths about what factors determine penis size, for example shoe size, height and masturbation.
According to the website, the most significant growth of the penis occurs during puberty, around 12-16 years of age.
A penis typically reaches its maximum length and girth when a person is 18 or 19 years old.
However, some lads experience penile growth well into their early 20s.
