Would you have scientific and/or medical references which establish that A-A are not mandatory for full transition of trans women ?
Any doctor will know that estrogen exerts a negative feedback on the pituitary gland and hypothalamus, thereby reducing LH and FSH production which signal testes to produce testosterone and maintain sperm production. If your doctor ignores this, run...FAST.
Studies have also suggested, in addition to this, that estrogen has the following anti-androgenic effects:
- reducing conversion of T to DHT
- increasing aromatase responsible for converting T to E
- downregulating (decreasing) androgen receptors.
The reason many doctors do not only use E is because they wrongfully believe that the doses of E needed to shut down T will increase health risks, especially liver damage and thrombosis, perhaps cardiovascular complications. This may have been, indeed true, with non bio-identical forms of estrogen but studies have shown when bio-estradiol is used, in high doses, in transsexual women and men with prostate cancer (49-91 yrs old), none of these complications occurred. Most of the time, estradiol was also taken non-orally. One can also bring up the situation of pregnant women who have extremely high levels and despite this, this neither increases breast cancer risk (on the contrary, inverse associations have been found) and DVT/embolism risks remain VERY low, under 0.02%.
I will PM you references.
