The cause of the short penis
1. The pathological cause of short penis
1.1, abnormal brain tissue structure: Children without brain deformed children have no hypothalamic secretion function. Even if the pituitary gland develops normally, due to non -promoting gonads to release hormones, testosterone secretion is less and caused.Congenital pituitary gland is not developed, some hypothalamus dysfunction caused by dysplasia of the brain tadpoles, and abnormalities such as cerebral deformities such as cerebral deformities of the cerebral disorders of the pillow brain swelling accompaniment.Both the small penis caused by insufficient gonad hormone secretion.In addition, it also leads to multiple deformities in other systems.
1.2. Congenital adenopulin release hormone deficiency with abnormal brain tissue: small penis caused by such causes is more common than the former, and the specific cause is unclear.Prader-Willi), Lawrence-Moon-Beidel syndrome, etc., often accompanied by multiple deformities. According to the research related to chromosomal and genetic abnormalities, there are also deficiency in gonadotropin release hormones, luteal generic hormones and other deficiency due to endocrine and biochemical metabolism.disease.
2. The physiological cause of short penis
2.1, genetic factors
The penis is the same as other organs of the body, and its size and morphological characteristics are controlled and influenced by genetic genes.
2.2. Development and nutritional status
Generally speaking, adult men are strong and tall. The external genitals include the development of the penis and scrotum, and the penis may be thick; otherwise, it may be relatively small.But it must be reminded that the size of the penis is not proportional to the height.
2.3, obese
In particular, men with full and lipsticks of the pubic bone joint and perineum often have poor development of the penis. Compared with the normal men's penis, the patients themselves look at their penis and think they are small.
2.4, others
With testosteritis, intangible testis, testicular dysplasia, etc., and endocrine imbalances, and insufficient male hormones, they may cause short penis.
3. Other reasons for short penis
3.1. The high -proliferation gonadotropic gonad function of the lesions is low. At this time, the lower mound brain and pituitary are normal and can issue strong instructions.
3.2. Low -promoting gonad hormone glandular dysfunction is hypertrophic. This is because the hypothalamus and pituitary lesions cannot be issued downward.
3.3. Part of the antygenosis 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 a urethral cracking.
Symptoms of short penis
1. Endocrine tests of small penis need to conduct a system of endocrinomiasis include chorionic gonadotropin stimulation test to detect whether the brain pituitary or testicular dysfunction is detected. Radio immunogenesis determines the testosterone (T) and estradiol (E2) (E2)The concentration is low, and both E2 and T are high.
2. The pathological examination of testicular live tissue is manifested in the dysplasia of raw sperm tubular epithelium, the glass -like or fibrosis at the base of the base, and no mature fine cells.Check the chromosome nucleus type for excessive gender abnormalities.The endocrine examination of unique small penis is normal.
3. The penis is particularly small and does not match the age, but the appearance is normal, the length and diameter ratio are normal. The average length of the length of the penis is more than 2.5 standard deviations, and some penis sponge develops poor body development.
4. Check that there is no scrotum, small testicles, soft, incomplete or missing abnormalities.
5. Anal pointer diagnosis and examination of the prostate is smaller than normal.
Short penis diagnosis
1. False penis shortness: refers to the penis in a non -erection state, although the length is less than 5cm, but it can significantly extend and thicken by 2 to 3 times in the erection state, and does not affect sexual life.
2. Curvable penis: Although the penis seems to be short, when the skin is pressed by the back of the penis, the normal size of the penis can be exposed.
3. Tianye: The penis is short, and the testis and the second side of the male are dysplasia. The chromosome group is 47, xxy, etc.
4. Penis scrotum melts (pimple -shaped penis): refers to the expansion of the scrutine skin forward, which is thin and wrinkled.
5, shrinking yang card: refers to the sudden onset of the penis, the penis and scrotum shrink, accompanied by the pain of the penis scrotum, sweat, palpitations.However, the development of the penis and the side sexual characteristics is normal.
