Understanding the Growth and Development of the Penis

The onset of puberty is the beginning of biological growth during adolescence; the point in which a child begins the transformation into an adult.

Growth and Development of the Penis
For many men, penis size is equated with masculinity

The changes that occur during puberty include:

  • sexual maturation
  • skeletal growth and increase in bone density
  • increases in weight and height
  • changes in the body’s physical composition

The increase in size of the male genitals, both the penis and scrotum, is another important development. This change in size in the male genitals is marked as being particularly important to men, as penis size is often associated with masculinity.

Magazines and Movies Are Not Representative

The last few decades have seen an increase in men’s dissatisfaction with their own bodies, particularly the size of their penis.

Dissatisfaction with a man’s penis size is typically characterized by the feeling that he does not measure up to other men in some way. A man must see other penises to be able to evaluate his own, and though many heterosexual men may have difficulty being able to find examples for comparison in real life, especially erect penises, they may turn to adult magazines and movies; an unrealistic method for comparison.

No Two Penises Are the Same

Penises come in a vast range of sizes, shapes and degrees of curvatures and so it is essential therefore to understand normal penis development and growth in order to attain an accurate comparison for penis size.

Sexual Maturity Stages

The scale which measures pubertal changes is generalized to allow for the variables associated with the puberty and its onset. The following scales are commonly accepted by biologists and sexologists to describe male genital development and are as follows:

  • Stage 1 (Preadolescent, before 11 years of age):

    The size and proportion of the penis, scrotal sac and testes become similar to those seen in early childhood.

  • Stage 2 (11-13 years of age):

    The skin and texture of the scrotal sac begins to change and there is an enlargement of the testes and scrotum. At 12 years old the body begins to take on more muscular definition and shape due to the production of hormones; testosterone in particular. The scrotum begins to redden and the skin will become thinner while the rest of the muscles within the body increase in mass.

  • Stage 3 (Puberty / 13-16 years of age):

    The penis and scrotum begin to enlarge and continue to grow until roughly two years later, though the stages of genital development ranges from male to male. The penis increases in size from both lengths to girth and is associated with the development of penile glands. The scrotal skin becomes darker and the testes and scrotum become more enlarged. Spontaneous erections occur throughout the life of the male, even during infancy, but because of the hormone production during puberty, boys will experience erections more frequently. These erections may not have any direct or indirect cause and may result in the boy having nocturnal emissions or “wet dreams”.

  • Stage 4 (Adulthood):

    The penis and scrotum have achieved the size that they will maintain during adulthood.

What Impacts Penile Growth?

Testosterone[1] is the most important factor of penis size, facial and body hair, and muscular development. The production of this hormone results in an increase in the size of the penis as well as the development of hair, yet it will not affect the size of the testes.

“Normal” or Average Penis Size

Research suggests that most men underestimate the size of their pride and joy

Due to the ever changing development and growth during puberty, the penis will appear differently in early adulthood than it would to someone who is age twenty. The average size and “normal” size range for the penis is as different as any other part of the body.

Penis size varies from male to male, as well as shape and girth. Some of the impacting factors are age, weight, height etc.

One study shows that the average length is an estimated 8.2 to 9.7 cm for length, with an average girth of 1.6 to 2.7 cm when flaccid, and an estimated 14 to 16.5 cm when erect.[2]

Recent medial and scientific advancements have made it possible to increase the penis size and enhance male performance. Conditions such as erectile dysfunction, impotency, Peyronie’s disease and other male sexual disorders are now treatable.
