How exactly does an anti estrogen help kickstart your natural test after a cycle?
Ive been hearing this alot lately, and was thinking about throwing some in with my clomid.
Well, Estrogen known to inhibit the Gonadotrophins(natural production of Testosterone) by sending negative feedbacks to the pituitary gland and the HTPA "hypothalamohypophysial testicular axis"(This happens when Estrogen saturates testosterone receptors in the hypothalamus region of the brain. The saturated hypothalamus then stops sending out a hormone to the pituitary gland to stimulate secretion of luteinizing hormone)
and Less Estrogen = More Testosterone production , More Estrogen = Less Testosterone production
and the exact mechanism of Clomid, it competitively inhibits Estrogen receptors from binding at Hypothalamus, gives a negative feedback to the Hypothalamus and pituitary gland as general that there is enough Estrogen around and there is no needing for more production as with all negative feedbacks mechanism, allows for unabated GnRH secretion, Increases pituitary sensitivity to GnRH which leads to Enhanced Luteinizing hormone (LH) release and Enhanced Follicle Stimulating Hormone (FSH) release
by mean, Clomid is mainly works by inhibiting Estrogen to get more LH/FSH production(Testosterone production)
so by taking something like Arimidex, which blocks the aromatase enzyme(which converts Testosterone into Estrogen in the body), and showed in many studies that it significantly lowers serum estradiol concentrations without even the presence of aromatization.
so Arimidex will going to help, by lowering Estradiol concentration in the blood which will going to bind to the hypothalamus and cause the inhibition, so by preventing it, less inhibition will occur and by the assistance of Clomid, it will gonna be perfect
Important note:
The Gonadotrophins including FSH (follicle stimulating hormone) and LH (luteinizing hormone) are responsible for the production of Testosterone/Estrogen/Progesterone and by inhibiting the Gonadotrophins as during the cycles, then there must be a low Testosterone, Low Progesterone and Low Estrogen level but the reason here fo why Estrogen is elavated
The lower Gonadotrophins and suppressed HPT-axis the higher SHBG (sex hormone-binding globulin) a protein produced by the liver, which binds free testosterone in the blood, making it less available to cell receptor sites while it increase serum Estradiol level and causes an inbalance in Testosterone/Estradiol levels.
I hope that's clear enough
