You are worried about saving your last testicle…
High levels of testosterone affect upstream regulation. HCG affects downstream production and forces the pituitary to excrete LH regardless of testosterone levels. This is why HCG is protective of testicular function in testosterone and spermatogenesis during cycle.
HCG is a safe and efficacious alternative or adjunct to TRT in men desiring to preserve fertility while treating their hypogonadism. HCG can also be used help restore spermatogenesis in men hypogonadal hypogonadism or steroid induced impairment of spermatogenesis.
Exogenous steroid use impairs spermatogenesis by promoting negative feedback on both the hypothalamus and pituitary gland.
The regulation of testosterone is controlled to maintain normal levels.The hypothalamus and the pituitary gland control the amount produced by the testes. The function of testicular testosterone production is not diminished by increased signaling demand. The testicles can only produce 7 mg/day but with Hcg, an increase in intra-testicular testosterone by 26% is not uncommon.
In response to gonadotrophin-releasing hormone from the hypothalamus, the pituitary gland produces luteinising hormone to the gonads and stimulates testosterone.
Increased testosterone, feeds back to suppress gonadotrophin-releasing hormone from the hypothalamus which, in turn, suppresses production of luteinising hormone by the pituitary gland.
Regarding your earlier steroid use, Chronic elevated testosterone shuts down the release of luteinising from the pituitary, which decreases of testosterone produced within the testes causing shrinking. Receptors like Androgen or GABA action potential receptor decay synaptic current prolongation from chronic AAS abuse may be better compared to organic and functional processes involved alcohol consumption. Prolonged, heavy abuse will have effects on the neurons that potentiate GABA. However in many cases, synaptic equilibrium returns for many having suspension of affecting substance. However 5000iu HCG is a common, successful therapy in fertility clinics to overcome deficiencies.
You say you have belly fat that prompted this post your not happy with.
Belly fat in men with love handles can be a definite sign of aromatization of testosterone to estrogen. Free Testosterone will show lower and total estrogen despite estradiol will be higher.
Fat cells become their own endocrine system and regulate estrogen production from testosterone. Using AI’s will help. Fat cells are like cancer. They fight to stay alive and grow despite increased metabolic rate from increased muscle mass. You can shrink the cells through diet and increased HIIT training especially when in a fasted state. Fat cells love glucose and triglycerides! Do what ever you can from spiking insulin. Eat low or no glycemic foods.
Increase in muscle mass, increase in androgen receptors, increased metabolic rate, increased caloric threshold. As far as increased Testosterone? Simply put, Yes.
Hope this helps!
