The normal gonadal function guarantees the executing of the reproductive and sexual mission of man . modification at this level lead to dysfunction of various organs such as the brain , muscle and sexual expanse . The performance of the hypothalamic - pituitary - gonadal axis vertebra depends on the secretion of several hormones . Gonadotropin - release hormone ( GnRH ) secreted by the hypothalamus stimulates the product of pituitary gonadotropins ( follicle stimulate endocrine , FSH ) and luteinizing internal secretion ( LH ) . follicle-stimulating hormone shape spermatogenesis in the seminiferous tubules of the testis and LH keep in line the secretion of testosterone by Leydig cells . In turn , the restraint of GnRH , FSH and LH depends on the production of inhibin by Sertoli cell and testosterone by Leydig cell . Inhibin inhibit the secernment of FSH and testosterone command the product of LH .
Androgens act in the specialization of outside crotch , sexual desire , the growth of alar and pubic fuzz , development of muscle mass , and pelt grain , the tone of vocalization , os geological formation and pubertal development .
Hypogonadism or decreased gonadal purpose represents an revision of the hypothalamic - pituitary gonadal bloc .
What Causes Low Testosterone Levels In Males?
Low testosterone levels in males or virile hypogonadism happen when the testicles arrest farm sperm , testosterone or both . There are three basic mechanisms :
In the first two cases , hormonal production is lessen but the hormonal response is normal ; in the third casing the production is normal but the answer is diminished . Hormonal want can occur before birth , beforepubertyor after puberty . The absence seizure of testosterone in the fetus leads to the comportment of ambiguous privates at birth . prepubescent testicular failure is characterized by decreased testicle size of it , small penis , decreased body hair , female voice , small prostate gland , lessen libido ( sexual desire ) and muscle mass .
In some cases , there is a eunuchoid habitus ( distance from the pubis to the floor is large than from the braincase to the pubis and the distance between the tip of the midway digit with the expand coat of arms is greater than the elevation . If it fall out after puberty , the skeletal proportions and the size of the penis are normal , the testicles are not as belittled as in the prepubescent loser but they are soft and have a volume of few than 15 cc . The body hair evaporate almost whole and the decrease of thelibido(sexual desire ) is ill-famed . Over the years , osteoporosisoccurs if the patient is not treated .
It is useful to sort elemental hypogonadism ( testicular failure ) from lowly hypogonadism ( trouble of the hypothalamic - pituitary axis ) . The term hypergonadotropic applies to the first and hypogonadotropic to the 2d .
The diagnosis of hypogonadism begins with a punctilious clinical account and the search for relevant findings during the forcible examination . The laboratory only verifies the clinical distrust . A full or free serum testosterone below the normal limits with increase FSH and LH confirms the front of a primary hypogonadism . There is controversy about the utility of entire versus liberal testosterone , since in some vitrine a decrease in total testosterone can be found with normal free testosterone . This is due to a decrease in the carrier protein of gonadal hormones ( SHBG ) . However , the free testosterone is hard to measure and the test is more expensive . That is why doctors initially range a full testosterone and reserve free testosterone for doubtful cases . In cases of lowly hypogonadism , serum testosterone is hardly belittle or is at a low normal limit point . The FSH and LH may also be low or in the normal down point of accumulation . There are several stimulation tests that could be used in special cases but are not of routine clinical use .
Conclusion
manful hypogonadism is common and is neither name nor treat frequently . The absorption of plasm testosterone also decreases from 0.5 % to 2.0 % per year after 50 years . Overweightanddiabetescontribute to the gonadal alterations of men .
The direction of men with hypogonadism has two objectives : attain richness and improve intimate characteristics .
