Is Low Testosterone Hereditary?
Recent researchers have identified the association of hereditary with low testosterone levels . The research have demonstrated that the markers , if present in a particular individual , may increase the risk of development of hypogonadism by 6 - 7 clip as compared to normal person . as luck would have it , as far as infertility due to these patrimonial disorders is pertain , treatments are usable in most of the cases .
Influence of Hereditary On Testosterone Levels
Various researches have indicated the presence of genetic factors in many cases of small testosterone . The scientist have key the transmissible marking responsible for for the virile hypogonadism . The presence of these markers on the genetic makeup of a person may increase the jeopardy of hypogonadism by 6 - 7 times as compare to the somebody who does not have these markers . Various protein have been found out which cut the production of testosterone . It has been found that presence of these markers carry the same risk of hypogonadism as carried by the known risk factor such asobesity , chronic kidney disease , type 2 diabetes , smokingand aging .
Kallmann Syndrome : This syndrome is because of the sport of ANOS1 gene . The expression of this gene shows ten - linked recessive pattern . Thus , a presence of unmarried written matter of this altered factor in male is sufficient to cause this syndrome . The main symptoms present with this mutation are delay puberty and vitiate sense of smell .
Prader - Willi Syndrome : The genetic mutation in thePrader - Willi Syndromeis generally not inherited . This syndrome is make due to the variation in the agnate chromosome 15 . The symptoms related to this syndrome are delayedpuberty , developing genital organ andinfertility .
Klinefelter Syndrome : This syndrome is make due to an extra Adam chromosome present in male so that the genotype read as 47 , XXY . These extra genes present have multiple effects on the physiological and mental development . The symptoms include small testes with low testosterone output and sterility .
Myotonic Dystrophy : Type 1 myotonic dystrophy is make by variation in DMPK gene while type 2 is do due to genetic mutation in CNBP gene . These patients have lower testosterone levels and higher gonadotrophin level as this term is frequently related to testicular atrophy .
Classification of Hypogonadism
The hypogonadism can be classified in to primary and secondary hypogonadism . The primary hypogonadism is due to the inability of testes to raise testosterone .
subaltern hypogonadism , also known as central hypogonadism , is due to the faulty signaling form the pituitary and hypothalamus to the testes for production of testosterone . The occurrent of low level of testosterone from the parturition is recognise as inborn hypogonadism while the gloomy tier developed later in biography is term as acquired hypogonadism .
Causes of Low Testosterone
Infection : The infection may trim down the capacity of the cell to produce testosterone or may also reduce the capacity of cells to produce chemical substance triggers required for release of testosterone . The viral transmission such as HIV infection also lead to virile hypogonadism .
egg Tumor And Therapy : The Leydig cells , which are responsible for the output of testosterone are present in testes . In case of any tumor in the testes , these cells are replaced by abnormal cancerous cells and thus the product of testosterone is reduced . Further , therapy including chemotherapy and irradiation also destroy the cells .
Pituitary Problems : Any problem in the pituitary such as pituitary tumor also reduces the spill of chemicals required to signal the output of testosterone .
transmissible Factors : Sometimes the low testosterone stage are also link up to the hereditary factor .
Injury To egg : Any injury or trauma to the testicles may lead to the reducing in testosterone synthesis thereby leading to primary hypogonadism .
Conclusion
In some cases , the down in the mouth testosterone levels are linked to hereditary . The genetic variation takes place , resulting in the expression of sure protein that reduces the level of testosterone . The gene most creditworthy for hypogonadism is sex hormone bond globulin cistron . The related conditions are Kallmann Syndrome , Prader - Willi Syndrome , Klinefelter Syndrome , and Myotonic Dystrophy .
