iNOS is known for releasing large amounts of nitric oxide as a defensive tactic. Nitric oxide is a free radical that can be used as a weapon and, therefore, sudden low testosterone essentially puts a huge oxidative load on the brain and may actually do some damage that leads to Parkinson's.  A further verification of this is the fact that, according to one study, men are times more likely to contract Parkinson's and that low testosterone levels have been associated with Parkinson's.  In addition, giving male Parkinson's patients testosterone can help with tremors. 
A 31-year-old man presenting with an 18-month history of sexual dysfunction resulting from severe adult-onset IHH (LH U/L, FSH U/L, T nmol/L). Initial therapy with 50 mg of clomiphene citrate (CC) three times a day for 7 days, with overnight LH pulse profiling and 9 am T levels evaluated at baseline and on completion. A 2-month washout period, followed by low-dose maintenance therapy (25-50 mg/d) for 4 months.
MAIN OUTCOME MEASURE(S):Baseline and stimulated T levels and LH pulsatility; effect on sexual function.
RESULT(S):Clomiphene therapy resulted in complete normalization of pulsatile gonadotropin secretion, serum T level, and sexual function. CONCLUSION(S):Isolated hypogonadotropic hypogonadism may result from an acquired defect of enhanced hypothalamic sensitivity to E-mediated negative feedback. Whereas direct T replacement therapy can further suppress endogenous gonadotropin secretion, treating IHH men with gonadotropins can stimulate endogenous T secretion and enhance fertility potential. On theoretical grounds, reversal of gonadotropin deficiency with CC might be expected to have a similar biological effect.
I did a 5 week program with an Age Management and Weight Loss facility here in TN. I lost 29 lbs in that 5 weeks giving myself daily HCG shots and seeing the DR once a week for the B12 Lipo Lean shot. It worked. It was the easiest diet I have ever done. I did not cheat not once. My family and friends sure noticed the difference. I ordered two bottles of the HCG drops to see if I can lose the additonal 25 lbs I want to use. I already know what I have to do but I will be exercising this round….HCG is a miracle drug for me. If I can do it anyone can do it….
