Male genital size is always a concern. Like other organs, male sex is also experiencing growth with age, and growth stops at a certain age and then shrinks during old age.
Dr. James Mourilyan Tanner, a professor endokrinologist child and at the Institute of Child Health, University of London, has spent years studying the stages of sexual development during puberty, which is famous for Tanner Stage.
At Tanner Stage there are five stages of reproductive development in males, a change in penis size of the child until adulthood.
The following stages of development according to Tanner Stage penis, as reported by lavistachurchofchrist.org, Friday (18/03/2011):
Toddlers (birth to age 6 months)
Usually penis boys born at a length of at least 2.5 cm. At the age of 6 months, the length of the penis will increase to at least 3 cm.
Stage 1 (children 1-8 years old)
This stage is when a man is still as a child, before puberty begins. No external changes are visible in the genitals and no secondary sex characteristics, such as hair growth. Testicular volume is about 1 to 3 milliliters. Penile length-age children is between 4-5 cm.
Phase 2 (adolescents 9-12 years)
This stage occurs when puberty begins, although the hormone causes sexual changes have increased for almost a year. At this stage the testes and scrotum begin to enlarge, with testicular volume was 4 to 6 milliliters.
Towards the end of this stage some hair growth can be detected near the base of the penis. Stage 2 usually begins between ages 9 to 16 years, but the average age is between 11 and 12 years.
Penile length in the early puberty usually average 5-7 cm.
Stage 3 (adolescents 13-14 years old)
At this stage the penis begin to elongate. Testes and scrotum continue to grow, with testicular volume is 7 to 16 milliliters. Pubic hair or hair around the genitals start to grow. Starting with the fuzz, but at the end of this phase the hair texture from rough sex.
At this stage, boys experience a growth spurt. Hair feet and hands began to emerge. The sound was starting weight at this point.
Stage 3 usually begins 2 years after stage 2 or the average age is 13 to 14 years. Penile length children in this age of 8-10 cm.
Stage 4 (teenagers 14-15 years)
In addition to growing longer, at this stage the size of the penis is also more broadly. Testes and scrotum continue to grow with testicular volume is 12 to 24 milliliters.
Pubic hair now covers most of the groin area between the thighs. Armpit hair begins to grow at an early stage. Also began to grow facial hair on the upper lip and chin. The voice continues to deepen and growth began to slow.
Stage 4 is usually from 1 to 2 years after phase 3. The average age is between 14 and 15 years. Childhood penile length is 10-12 cm.
Stage 5 (adolescents 16-17 years)
While all the growth has stopped, the body has made an adult form. Shoulders began to expand and chest hair starting to appear. Full facial hair and may need to be shaved.
Pubic hair covers the groin and has spread to the thighs. The penis and testicles now has the adult form and its growth began to slow or in some people stop growing. testicular volume of 16 to 27 milliliters.
This stage usually begins two years after stage 4. The average age is between 16 and 17 years. The average child this age has a penis length of 10 cm to 15 cm.
The final stage (stop growing)
Usually the growth of the penis this will stop when entering the age of 18 years to 21 years. The average size of a normal adult male is 12.7 cm to 15.24 cm.
Shrinkage phase (above 40 years)
The body begins to experience shrinkage, including the penis of a man when he entered 40 years and over.
