Puberty is an incredibly complex period and runs over a fairly long period of time, which begins with an increase in hormones, which in turn triggers changes in the body. Each individual’s individual puberty calendar is different.
The body’s hormones are responsible for changes in the body. These hormones start working on the testicles, causing them to produce testosterone.
Testosterone is the primary hormone responsible for most of the changes a young man goes through.
But when puberty begins
The average age at which boys start puberty is around 11 and a half years. However, it can start anywhere between the ages of 9 and 15. Physical changes usually take 3 to 4 years to complete.
Below is an overview of some physical changes that kids can expect during these years. How the male sex develops

  • The stages of development
  • At what age does the development phase stop altogether
  • As long as the penis can continue to develop

Of course, when it comes to male sex, it’s not just about the penis.
Let’s try to go in order, starting with the enlargement of the testicles and scrotum.
Puberty is heralded by an almost doubling in the size of the testicles and scrotal sac. As the testicles continue to grow, the skin of the scrotum darkens, enlarges, thins, begins to hang from the body and become dotted with tiny bumps. These are hair follicles. In most boys, one testicle (usually the left) hangs lower than the other.
A boy can have adult-sized genitals as early as the age of thirteen or up to eighteen. The penis begins to grow first in length, then in width. Teenage males seem to spend an inordinate amount of time checking their penis and covertly (or openly) confronting other boys. Their number one concern
Undoubtedly: size. What are the hormones responsible for male development
The hypothalamus and pituitary gland, found in the brain, initiate puberty. The hypothalamus secretes luteinizing hormone-releasing hormone, which stimulates the pituitary gland to secrete luteinizing hormone and follicle-stimulating hormone. Luteinizing hormone causes the testes to produce testosterone. Follicle-stimulating hormone (plus testosterone) causes the testes to produce sperm.
Testosterone, therefore, is responsible for the development of the so-called secondary sexual characteristics, which are responsible for stimulating male development; among these are also includes additional features and which have nothing to do with reproduction, such as fluffing and lowering of the vocal pitch).

  • Enlargement of the scrotum and testicles
  • Penis enlargement (between 11 and a half and 13 years);
  • Enlargement of the seminal vesicles and prostate gland;
  • Appearance of hair;
  • Appearance of hair on the face and under the arms (which occurs after the onset of pubic hair growth)
  • Ejaculation becomes possible (usually between the ages of 12 and 14).

Stages of development
In boys, penile development usually begins between the ages of 10 and 16. Once started, it lasts 2 to 5 years. But every child is different. And there is a wide range to define what is “normal”.
Boys may start puberty a little earlier or later and finish earlier or later than other boys or friends.
People are all a little different from each other, so it makes sense that they don’t all develop the same way. No two people are at exactly the same stage as they go through puberty, and each changes at their own pace. At what age does the development phase stop altogether
From 18 to 21, the penis is unlikely to continue to grow in length or girth. The timeline in which a penis can grow can vary from person to person.
One young man may have reached the final size of his penis at 14, while another may continue to grow until college. There is no fixed or quick rule here. As long as the penis can continue to develop
As adults, we are all familiar with the period of early adolescence when our bodies change rapidly, seemingly overnight. For men, the voice drops, pimples pop up, and body hair begins to show.
Growth of the penis and testicles also begins during puberty. This growth continues during and until the end of puberty.
That said, the timeline of puberty varies from person to person.
In general, testicular growth can start around age 10-13 and penis growth can start around age 11-14. Puberty generally ends for boys aged 16-21. This is the time when testosterone begins to stabilize after the surge of puberty, and then begins a long and gradual descent.
This important hormone, essential for male development, begins its downward path that often causes libido problems for men. Very often these are forced to use supplements or drugs to restore normal hormone levels.
