Is the penis shape only one? And how does it change over the years?

Summary

• The shape of the penis differs from man to man and varies with time
• The shape of the penis changes as we age
• Changes resulting from the drop in testosterone levels
• Other causes of problems related to the sexual sphere

The shape of the penis differs from man to man and varies with time
. The shape of the penis and
its size vary from individual to individual. In most
cases the typical feature is the cylindrical shape, with a
wider or more pronounced head (glans).
Given this, the male genital organ can present itself:

• curved
  down
• curved
  to the right
• straight ahead
• the
  base can be wider than the head, defining a
  conical shape
• the
  base may be narrower than the head.

Differences
in length and thickness can then be recorded. The shape of the penis changes with age
. The
penis also undergoes a series of changes over the course of life. The
various phases are mainly controlled by
testosterone levels.

• Between
  the ages of 9 and 15 ,
  puberty begins bringing the first changes. The pituitary gland
  releases hormones that cause
  testosterone production , the testicles,
  scrotum, penis and pubic hair begin to grow. Testosterone levels
  peak in the late teens through
  early 20s. From this moment on they begin to decline.
• The amount of testosterone
  decreases slightly between the ages of 20 and 40 ,
  but at this stage the change felt is minimal.
• After age
  40
  , total testosterone levels may drop slightly. But
  the body slowly begins to make a protein called sex hormone binding globulin (
  SHBG). This binds to testosterone
  in the blood and reduces the amount the body has available
  to use.

Changes following a drop in testosterone levels
As
testosterone levels decrease, you may notice
other physical changes:

• Pubic hair , like other body hair, thins and can turn gray.
• The size of the penis. It might look smaller, even when the actual size probably hasn’t changed at all. The idea of ​​a change may be a greater concentration of fat on the pubic bone just above the penis, the area may sag and make the organ appear smaller.
• Penis shape. In some men, the penis can become curved with age. This change can affect length, girth and functionality. This condition, called induratio penis Plastica, is caused by physical trauma, which can also occur during sexual intercourse. The curvature is caused , during the healing process, by the formation of scar tissue along the tunica albuginea, a sheath that lines the corpora cavernosa. The scar part fails to expand adequately, thus causing the onset of a curvature. This problem can be remedied by correcting it surgically or with a drug treatment, depending on the specific case.
• Testicles: The small organs inside the scrotum have the main function of producing sperm. As testosterone levels drop, sperm production slows and shrinks. When testosterone replacement therapy is performed, the pituitary gland stops sending signals to the testicles to produce testosterone and shrinkage is noted.
• Scrotum: its task is to control the temperature of the testicles. It is lined with smooth muscles that contract and release to bring the testicles closer to the body, to keep them warm, or move them apart to lower the temperature. As we age, the muscles atrophy, the elasticity of the skin is reduced and the scrotum is visibly more relaxed. The onset of some conditions can then affect the shape of the penis . One example is hydrocele , an excess buildup of fluid around one or both testicles that occurs after age 40 and results in an increase in the size of the scrotum.
• Penis function. The nerves in the penis become less sensitive as we age, this can lead to problems with arousal and reaching orgasm. When testosterone levels decrease, erectile function is impaired, resulting in a reduction in stiffness, but it does not necessarily undermine the ability to have intercourse.

Other causes of problems related to the sexual sphere
The difficulties encountered in the sexual sphere can also be determined by the inability of the cavernous tissue to retain blood in the penis. When this happens it is possible to have an erection, but it is difficult to maintain it. The loss of hardness is explained in a simple way: the blood flows properly, but the muscle surrounding your erectile tissue, as you age, can no longer hold it.
Changes in the sexual organs and sexuality are a normal stage of aging. When these represent a problem in life and relationships, it is advisable to seek a specialist medical consultation to get an expert opinion and find an effective solution.
