In order to further explain the cause of the large or small penis, let us review the occurrence and development of the penis together.For the convenience of narrative, we divide it into four stages:
(1) In the 10-12 weeks of pregnancy, the penis has just been differentiated, only 3.5 mm long. At this time, the testosterone produced by the HCG secreted by the placenta.
(2) In the middle and 6 months of pregnancy, the penis grows rapidly, and it has reached 2.5-3.5 cm at the time of birth.
(3) After birth to before adolescence (around 7 years old), the penis grows slowly. This is because the hypothalamus and pituitary development are slow, and the level of testosterone levels is also low.
(4) After the beginning of the adolescence, the secretion of pituitary and testicular hormones is strong, and the penis grows rapidly. In just 5 years, it reaches the level of adults and increases thickening.When the level of senile hormones is significantly reduced or surgery is trending, the penis can be secondary degraded.After many years of discontinuation of secondary discontinuation, pathological degeneration may also be caused. This is not the general problem of using waste and degeneration, but the consequences of degenerative changes in smooth muscle fibers.
In short, the division and development of the penis depend on the testosterone level in the body. If the testosterone secretion is insufficient during the 6-9 months of pregnancy, the penis development is lower than the normal rate, and the penis is smaller at birth.
So, what is the real?The penis is shorter than 2.5 cm before adolescence, as short as 5 cm after adolescence, and the development is not normal, and there is no erectile function; especially the secondary sexual development, no fertility, no sperm, at this time, it can be considered that the penis development is developed.unusual.The cause of the real small penis includes:
(1) Highly promoting gonadotropic gonad function that is originally involved in testicular gonads. At this time, the brain and pituitary gland are normal and can issue strong instructions.
(2) Low -proliferative gonadotrophic gonad functional dysfunction is because the hypothalamus and pituitary lesions cannot be issued downward.The above two diseases have been introduced separately.
(3) Partial anti -androgen syndrome, that is, the penis is not sensitive to therogens, the testosterone level in the patient's body is normal, but the second sexual characteristics are abnormal, and there may even be urethral cracking.
(4) The special small penis is unknown.
Let's go back to the woman in front of them. Because she was pregnant 9 months after marriage, and gave birth to a son safely, it shows that her husband's sexual function is normal, and there will be no problems such as endocrine. The penis obviously belongs to normalscope.There is no need to worry about such normal physiological differences. As for female sexual satisfaction, it is caused by factors such as sexual knowledge and sexual skills on both sides, which have nothing to do with the size of the penis.
