Trenbolone, an esterified form of testosterone, caused Frank's testicles to shrink because the steroid trenbolone produces three times the effects of testosterone, making the body appear larger and performing certain roles of testosterone, but lacking the actual testosterone needed for the body to function properly. Since testosterone was replaced by trenbolone, sperm production has decreased, shrinking his testicles. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get an Original Essay To test the hypothesis, two males, both in their 20s and of the same build and weight, will be assigned the same workout to complete for per month, along with the same eating plan. One male will be given trenbolone and the other male will not be given any steroid. Throughout the month, every seven days, both males will measure body fat, muscle, hair growth, weight and the circumference of certain areas such as biceps and thighs. After the end of the month, every male will also take a blood test to analyze the testosterone levels in his body. The blood test will reveal GnRH, LH and FSH levels. To counteract trenbolone acetate, which limits the release of LH (luteinizing hormone) and FSH (follicle stimulating hormone), users can inject human chorionic gonadotropin, which has a similar structure effect in LH and FSH. This treatment may work because, since there is no testosterone activating the receptors to release the hormones, the chemical injection would allow the hormones to pass through the body and function as if they were released naturally. By manually injecting the hormones, it can provide the amount needed to compensate for the side effects since the missing hormones that testosterone helps to release are not present.

Get a Custom Essay For men who have had testicular cancer and have had surgical removal of one of their testicles, the remaining testicle will enlarge, almost double. The increased growth of the testicle is due to the remaining testicles trying to compensate and function as if they both still exist. As the testicle tries to compensate for both, the result is an overproduction of sperm, testosterone, and male hormones. The brain, particularly the pituitary gland which releases hormones such as LH, testosterone and FSH, requires increased production from the individual testicle.
