Tanner Stages

Teenagers are experiencing different forms of maturation and these include cognitive which pertains to the development of the formal operational thought, psychosocial or the phases of adolescence and biologic. The complex series of the biologic changes are called puberty and such changes might affect the psychosocial factors. The most apparent changes during the period of puberty are growth in stature as well as the development of the secondary sexual features. Equivalently profound are the changes in the body composition, fertility achievement, and changes in most systems of the body like the neuroendocrine axis, size, bone and mineralization, including the cardiovascular system.

As a sample, the normal cardiovascular changes that involve the greater aerobic energy reserve, blood pressure change and electrocardiographic changes take place during the puberty period.

Theoretically, pubertal maturation could be described when it comes to sequence, tempo and timing and the sequence of these changes in the secondary sexual characteristics which was categorized by the different groups. Since the onset and the progression of puberty are highly variable, Tanner proposed the scale and it is uniformly recognized today, in order to define the start and progress of the pubertal changes. Girls and boys are rated on the 5-point scale wherein the boys will be rated for the genital development as well as the growth of pubic hair while the girls will be rated for breast development as well as pubic hair growth.

The growth of pubic hair in girls is staged as follows:

Stage 1 or Preadolescent – vellos hair is developed above the pubes and there’s no sexual hair present.

Stage 2 – there is sparse, pigmented, long and downy hair that can be either slightly curled or straight. The strands of hair are mostly seen along the labia.

Stage 3 – considerably darker, curlier and coarser sexual hairs are present and are now sparsely spread through the junction of pubes.

Stage 4 – the distribution of hair is of the adult kind but it decreased in the overall quantity. There’s no spread to medial surface of thighs.

Stage 5 – hair is adult when it comes to type and quantity and it appears to have that inverse triangle of the feminine form.

Meanwhile, the stages of male pubic hair development are as follows:

Stage 1 – vellos hair are present above the pubes.

Stage 3 – the hair has become considerably coarser, darker and curlier and the distribution is now all over the pubes junction.

Stage 4 – the distribution of hair is now of the adult type but is less than that of adults.

Stage 5 – the distribution is adult type when it comes to quantity and it forms an inverse triangle.
