When puberty begins

It is impossible to establish the precise moment when an individual enters puberty. In general, it refers to the onset of puberty at 13 years in girls and 15 years in boys. As well as the beginning, the duration of this phase of life also varies from person to person.

What is precocious puberty

Early puberty refers to the anticipation of this period of life. In general, puberty is considered early when it starts at 8 years old in girls and 9 years old in boys. Most of the time, this anticipation is normal. However, it can indicate the presence of a tumor in the ovaries or testicles and diseases such as congenital adrenal hyperplasia and hypothyroidism.

In addition, child and adolescent health experts have found that children have entered puberty earlier and earlier. Among the causes of this situation are obesity (increasingly common among children), stress and contact with so-called endocrine disruptors, chemicals that can affect the individual’s hormonal balance.

Female puberty

The initial phenomenon of female puberty is the entry into circulation of pituitary hormones. Follicle stimulating hormone (FSH) causes the development of follicles located in the ovaries. It is there that the egg is formed and matures, which can then be fertilized by sperm. It is also in the ovaries that estrogen, the female hormone, is produced. Ovary maturation does not occur independently. It is revealed in the appearance of secondary sexual characters, mainly the breast growth around 10 years old. This phenomenon proves the activity of the first follicles that start their maturation process.

Female physical changes

Under the action of estrogen, internal genitals (vagina, uterus and fallopian tubes) change and evolve until they take their definitive form into adulthood. The increased secretion of adrenal hormones is responsible for the growth of hair in the pubis and also in the armpits. They also favor increasing the height of the young woman.

When the uterus and ovaries reach a sufficient maturation stage between 10 and 16 years of age, the girl begins to live with menstrual cycles. In a year or two after it starts, cycles become regular. This period also causes the elongation of the limbs, the more harmonious distribution of muscle mass, modeling of the silhouette in a typically feminine aspect.

Male puberty

The hormones secreted by the pituitary cause testicle development. Follicle stimulating hormone (FSH) promotes the maturation of sperm while luteinizing hormone (LH) influences the multiplication and activity of Leydig cells, present in the testicles. At that time, the typical male hormone also comes into play: testosterone. Its action causes the appearance of the first hairs and bone and muscle development.

Male physical changes

Physical and sexual character changes in boys follow a chronological order. First, between 11 and 14, the first hairs appear on the pubis. At that time, the sexual organs also increase. Then, hairs appear on the armpits and on the face and the tone of voice becomes more serious. At the same time, the legs stretch and the arms and abdominal area become more muscular. At the end of puberty, the child is completely transformed into a man.
