What is Thin penis?
When penis is somewhat thinner than average, is called thin penis. This thin penis is found in approximately two percent of males .The thin penis may occur as single disorder or in some persons it may be associated with small penis. In some persons penis is so thin that as in children. It makes them sexually unsure of his sexuality and decreases their confidence. They feel inferiority complex in exposing themselves in public places as in swimming pools & sea beaches etc. Thus it must be consulted urgently, so that diagnosis and treatment is done by team of hormone specialist & micro vascular surgeon. For this you consult at our sex n hormone center for complete diagnosis & treatment. In majority cases proper diagnosis & hormone therapy of about one year duration leads to penis growth in girth and normalization of penis in length & thickness. Thus you come to our center where doctor have experience of treating such problems. In very-2 rare cases surgical intervention is needed in which case by microsurgery technique the penis girth enhancement is achieved in length as well as in thickness (i.e. girth) if required.
Causes Of Thin Penis
The following are the major cause of thin penis & small Penis It may occur due to:
Male Hormones Disorder
Hypogonadotropic hypogonadism (hypothalamic or pituitary deficiencies) Hypogonadisms, Hypothyroidisms, Testosterone deficiency, hyperprolactinemias,
Hypogonadotropics states: Hypothalamic – pituitary deficiencies: Idiopathic GnRH deficiency, Kallman syndromes, Prader-Willi syndromes, Laurence-Moon-Biedl syndromes, pituitary hypoplasia, Trauma, post surgical, postiradiation, Tumour (Adenoma, craniopharyngioma, other), Vascular (pituitary infraction, carotid aneurysm), Infiltrative (Sarcoidosis, histiocytosis, hemochromatosis) Autoimmune hypophysitis, drug-induced hyperprolactinemia, untreated endocrinopathies, Diabetics Glucorticoid excess, Hypopituitarisms, Cushings disease, Addisons disease. Isolated gonadotropin deficiency (non acquired): Pituitary, Hypothalamic Associated with multiple pituitary hormone deficiencies: Idiopathic pan hypo pituitarism (hypothalamic defects), Pituitary dysgenesis, Following inflammation, Infiltrative or destructive processes (autoimmune, hemosiderosis), Fertile eunuch syndrome, Idiopathic hypopituitarism, : Hypogonadotropic hypogonadism (hypothalamic or pituitary deficiencies) Hypogonadisms, Hypothyroidisms, Testosterone deficiency, hyperprolactinemias,
Hyperogonadotropic hypogonadism: testicular failure, development defect, drugs, trauma, congenital defect, congenital adrenal hyperplasia, Chromosomal defect, testosterone hormone biosynthetic defect, Mumps orchitis leading to testicular atrophy, Primary testicular defect-disorders of testicular differentiation or inborn errors of testosterone synthesis, Klinefelter syndrome, Other X polysomies (i.e. XXXXY, XXXY) Rainbow syndrome,
Partial androgen insensitivity
Growths Hormones Deficiency
Thyroids hormones deficiency
Idiopathic thin phallus: In many patients all the hormone growth factor & every thing else is normal, still they have small genitalia. This occurs due to Decreased capacity of penile tissue to grow. This occurs due to defective morphogenesis of the penis in utero so that its growing capacity decreases later in life. This is also one of the common causes of small & thin penis.
For diagnosis of cause of investigation following tests are required. These tests include Complete male hormone profile.
- Thyroids test
- Serum prolactin
- Ultrasound of testis
- Growth Hormone analysis
- DHT Level
- Other tests which may be required depending on likelihood of the any of above causes.
In biochemistry liver function or kidney function tests are done.
Dynamic test to judge functional capacity of testis whether testis has the capacity to function normally or not. In this test we inject single injection of gonadotropin as intramuscular injection then three day later the rise in concentration of male hormone is seen to asses whether testis has capacity to function normally or not.
Chromosomal analysis is done to see the genetic structure of testis, because there are many chromosome disorders, which lead to small penis. Capacity of generation of active testosterone i.e. DHT is tested. This DHT generation test is abnormal in some cases of small penis / thin penis /underdeveloped penis.
Tests to locate testis as ultrasonography or C.T. Scan abdomen is needed if testis is not palpable.
- MRI / CT SCAN head if suspecting hypogonadotropic hypogonadism.
- Serum inhibin is tested which tells that whether testis is functioning or not.
- Serum Iron, T.I.B.C. & ferritin concentration tested for hypogonadism due to hemochromatosis.
- Combined Pituitary hormone tests are performed when suspecting pituitary disorder.
- Molecular genetic studies done in some special cases.
- Serum estrogen increased whenever testicular function is decreased.
- Serum DHT is low in some conditions when generation of dihydrotestosterone is decreased.
Assessment of androgen receptor is done when needed, Dynamic tests as HCG test, response to antiestrogen & gonadotropin releasing hormone tests.
Interpretation of all above tests one need to be expert of hormone diseases with good experience. Based on above test result diagnosis of cause of small /or thin penis is made. Once the cause is found then treatment becomes very easy with good results.
