Standards of puberty boys
Each person in his own way, of course, unique and unique, does not look like everyone else's height, weight, facial features and the totality of all other individual characteristics. Individual way from the beginning of life is already the most growth and development, the transformation from a child into an adult. Important in this is the achievement of sexual maturity and self-identification of themselves, in this case, as men. After all, we all come from childhood, and this wonderful time, as well as a transitional puberty period from childhood to adulthood, is very important. There is this transition in each individual person in different ways, but there are some standards for puberty boys.
The first criterion is the age, in which the first signs of the fact that the child's body activates the processes due to which the childbearing function should be actualized in the course of time is noted. Sexual maturation of boys begins in 11-12 years. Do not exceed the limits of the norm is also 14-15-year-old age.
Further, the change in the size of the genital organs is assessed. During puberty testicles increase from 2.7 cm in 7 years to 2.8-3 cm at the time of puberty. By the 13th year - up to 3,6-3,7 cm.
A sexual member from 7 years before the puberty period grows from 3-3.5 cm to 3.8 cm and in 13 years is 6.3 cm, respectively.
At 15 years, the size of the testicles usually increases to 4 cm, and the penis reaches 6.7 centimeters.
Another indicator is the appearance of the hair on the body. At first, the hair grows on the pubis, and by 14-15 years - in the armpits. At the same time, there is an increase in the youthful cannon on the chin and above the upper lip.
Approximately at the same time, by the 14th year, pollutions often begin to appear.
During the puberty period of boys, there are two main growth spikes. At the age of 10-11 years the child can stretch for 10 cm. By the age of 13, it is possible to add from 7 to 8 centimeters.
Standards of puberty boys, of course, are indicative and very average. Some variability, of course, is possible and somewhere even inevitable. But the differences do not necessarily and not in every case indicate the presence of serious abnormalities in the development of the child. If, of course, their values are not too out of the ordinary.
Stages of puberty boys
During the puberty period, one after another, different stages of puberty of boys alternate. Often, right up until the very moment when the child begins to show the first signs of the beginnings of him that form the prerequisites to the fact that in the future he will acquire the ability to perform the genital function, his general development is stable and uniform. At the same time, there are not any obvious and significant changes in the hormonal background. To their peak activity, all the processes associated with the puberty of boys come mostly two years later than the young women. Noticeable changes that occur with boys become apparent only after reaching the age of 12-13.
According to many andrologists, how strong will the sexual constitution of the future man be due primarily to how early the puberty of the boy began. With regard to this statement, however, it is necessary to make a note that it is fair only when the child has not revealed any disturbances in the functioning of the endocrine system.
Among the main signs of advancing adulthood is an increase in the penis, which begins about the 11th year. The beginning of the active restructuring of the organism is also indicated by the onset of an increase in the size of the testicles at the age of 11-12 years.
At the age of 12-13 years, pubic hair begins to grow in puberty puberty. At first, the shape of the hair is similar to the rhombus, and in the future, from the age of 17-18, the internal surfaces of the thighs join the area of hair growth. Subsequently, there is complete body hair on the male type of hair. Vegetation on the face in the form of the first gently gun over the upper lip first appears in 13-14 years. At 15-16 some adolescents can flaunt a sufficiently pronounced and expressive mustache. The appearance of a full beard should be expected for years to 17-18.
This phenomenon typical for the pubertal period of boys as "breaking voices" which mutates because the thyroid cartilage in the larynx develops into the "Adam's apple" appears in the 13-14 year of life. As a rule, the Adam's apple, which was finally formed, becomes 17 years old. At this age, the young man already finds his own voice with a characteristic male timbre.
The production of male sex cells - the processes of spermatogenesis are started from the age of 14-15, which is accompanied by cases of involuntary ejaculation - pollutions.
The stages of puberty of boys come to an end in the age period from 16 to 20 years. Nevertheless, the onset of sexual maturity does not automatically mean that the young man can definitely be considered as fully mature psychologically. Psychological maturity and the formation of personality comes and go somewhat later.
Signs of puberty in boys
Signs of puberty in boys are manifested in a number of specific changes taking place in the pubertal period and are reflected both in their external manifestations and affecting the functioning of various organs and systems of the body.
The body of the boy during puberty intensively grows, the child becomes taller, the total muscle mass increases. The width of the shoulder girdle increases, the figure begins to acquire proportions typical for the male body. Sexual organs - penis and testicles increase in size.
Gradually, the body develops a scalp, starting with the groin, scrotum, armpit, and then all over the body. Then the hair appears on the face. At first a few hairs can break through at the corners of the upper lip and on the cheeks in the upper part of them. For a year after that, the juvenile fluff appears also above the upper lip in the middle.
In the process of puberty boys may have problems with the skin. In view of the hormone in the body, the functioning of the sweat and sebaceous glands adversely affects the body, which causes an increased fat content of the skin. And this, in turn, can provoke the appearance of acne and acne on the body and face.
The vocal cords grow in size and the throat muscles develop, and besides this, an Adam's apple - an Adam's apple - is formed, which serves as a reason for breaking the voice and its coarsening. This process begins at the age of about 13 years and after the expiration of a two-year period leads to the final formation of the voice.
In addition to the above changes, that they undergo the body of a boy during puberty, it is also necessary to bring in those characteristic features that are peculiar to the psycho-emotional state in this segment of his life's path that is not easy for the child. The central nervous system is in an extremely excitable state, behavioral reactions can often be unpredictable and highly contradictory.
These signs of puberty in boys are caused by a rapid rate of both the ongoing restructuring of the whole organism and the change in the whole self-perception and a new assessment of oneself in the light of many factors associated with the process of reaching puberty. To them, a boy who finds himself on the road from being a child to a man can be very difficult to adapt, and therefore understanding and support from parents and close people is very important.
Early puberty in boys
To say that early puberty occurs in boys is possible mainly on the basis of the fact that if the first pubertal signs are noted in a child earlier than he managed to reach the age of 9.
As well as the delay in sexual development, premature onset of maturation is a weighty argument in favor of not having to postpone this matter for a long time to consult a doctor. Suspicion in this context should be caused by the increased size of the testicles, abnormally fast growth of the body exceeding the rates of the average age norm, the appearance of acne on the skin, the embolism of the pubic and underarms, the growth of facial hair, and the child's too low and coarse, broken voice.
Too early admission by a boy during pubertal period is able to have as its main causes the presence of abnormal development of genital organs, thyroid dysfunction, tumor formation in the brain, the consequences of head trauma, complications due to transferred infectious diseases such as encephalitis and meningitis, brain disorders.
This is based mainly on the fact that it is the hypophysis and hypothalamus that participate in the regulation of hormonal secretion by peripheral sex glands. In addition to the early puberty, boys are able to bring some of the factors of heredity. So the probability of premature puberty is high, when the child has excessive body weight.
As the main negative consequence of the early puberty of boys can be called the fact that when a child stops growing. This is due to the fact that the sex hormones in this way negatively affect the bones that the growth zones are closing - those areas that provide an increase in length. Because of this, too early to become sexually mature boys are much inferior in growth to their peers.
Early puberty in boys is successfully treated with modern medical devices. The only prerequisite is the timely detection of the signs of such a process and the appropriate methods. The medical effect is directed depending on the established causes against the underlying disease, or special drugs that inhibit the secretion of sex hormones can be prescribed until the growth processes are completed.

Delayed puberty in boys
Delay in puberty in boys is generally noted if, after reaching the age of 14, the child does not have any signs of a puberty period.
This fact, however, does not mean that it should cause suspicion, in that it is provoked by the presence of any kind of anomalies in development. And perhaps, it is conditioned by some genetic peculiarities, the hereditary predisposition of all or most of the male representatives of a particular family to the late onset of development of their ability to procreate. This phenomenon is quite often known as the constitutional delay of physical and sexual maturation. The sexual maturation of boys in this case is preceded by a period with an absolutely normal rate of growth, the intensification of which and the appearance of characteristics characteristic of pubertal can begin and only by 15 years.
To delay the puberty of boys is capable of the presence of diseases, which lead to significant disturbances of the hormonal background. This can occur in connection with a tumor affecting the pituitary gland and the hypothalamus - the appendages of the brain responsible for the processes of puberty. Prevent sexual development may be insufficient or complete cessation of the production of hormones important for the growth of genital organs - gonadotropins. In a number of chronic diseases of the kidneys, diabetes mellitus, etc., the pubertal period is also often delayed.
With a delay in sexual development in boys, with relatively long upper and lower extremities, there is a frail physique, a high waist line, in body proportions the width of the hips exceeds the width of the shoulders. There is an underdevelopment of the genital organs, a penis is very small, the scrotum does not hang, there is no hair embolism of the pubis and armpits, there are no pollutions.
If there is a delay in puberty in boys, it should be borne in mind that it is fraught with at least an aggravation of the psycho-emotional state of a teenager with this problem, and later threatens infertility. At the same time, treatment does not present any particular difficulties if timely reasons are established and necessary medical measures are prescribed. In adolescence, you can cope with it within 2-3 months.

Later puberty in boys
Later, puberty in boys in some cases may not be directly related to any developmental abnormality, but rather be the norm within the limits of some single families in which puberty in men usually begins later than in adults, which is the total averaged norm. This is a general trend for such a family and the puberty of boys, starting a little later, further occurs with a perfectly normal rate of growth and development.
There are a number of characteristic features on the basis of which it becomes possible to ascertain later the onset of pubertal period in boys. The most obvious and obvious difference of these children is hypostature - that is, they basically have growth lower than their peers. The next symptom is that with the boy reaching the age of 15, he did not have an increase in the testicles. Talk about late puberty in boys can also be based on the fact that by these years there is no growth of pubic hair.
By late puberty, boys are able to bring the child's presence of certain chromosomal abnormalities, in particular Klinefelter's syndrome. In this genetic disease, the female chromosome Y is joined to the male chromosome set XY in a single quantity or several at once. As a result, there are all kinds of disruptions in the functioning of the endocrine system, one of the manifestations of which is a decrease in the production of male sex hormones in the testicles. Tumor lesion of the pituitary or hypothalamus - the zone in the brain that is associated with the processes of puberty, provokes a decrease in the number of gonadotropins, under the influence of which there is an active growth of the genital organs.
So, later puberty in boys occurs due to heredity, as well as against a background of a number of diseases with a violation of the hormonal balance in the body, which is reflected in the slowing down of body growth and the development of the genital organs of boys. When the onset of puberty occurs at a slightly later time than at the age of what is considered the norm, and then goes with a normal pace, this often can not require special correction. Medical measures in the event of an abnormal delay in the entry of the child into the puberty period are mainly reduced to the treatment of the underlying disease that caused it.
