Testosterone is answerable for the sex drive for people. Restoring testosterone to youthful levels in people can change the situation. Often, people automatically assume that as they age, their sexuality will decrease. Testosterone can take a critical role in helping to save and even renew sexual function. Testosterone production starts in a head. When the hypothalamus detects a deficiency of testosterone in the blood, it secretes a an organic compound produced by a plant gonadotrophin-releasing hormone to the pituitary gland. This prompts the pituitary to secrete luteinizing hormone.

It happens, when the testes lose ability to make testosterone, no matter how much luteinizing hormone is being made. This type of testosterone deficiency is determined when blood tests show high levels of luteinizing hormone and low levels of testosterone. The relating to the pituitary gland is telling the testes to produce testosterone, but the testes have lost their functionality. The hypothalamus fails to make capable amounts of luteinizing hormone, therefore preventing healthy testes from secreting testosterone. Blood testing can determine whether adequate amounts of luteinizing hormone are being secreted by the pituitary gland and help settle the appropriate therapeutic compare. If serum testosterone levels are too low, it is important to diagnose the cause, therapies exist to safely renew testosterone to youthful levels in any person, who does not already have prostate cancer.
