AIs and E2 from HCG

[skullmaggots]

I'll keep this simple, but I've read all sorts of things on this. Can the E2 increase experienced from adding HCG to your TRT be controlled via an AI? If not, then how an earth does anyone take HCG? My e2 shot up fom 35pg/mL to approx 80pg/mL. This has lead to an increase in libido but a decrease in my ability to get or maintain an erection.

I am doing bloods, and second test is tomorrow. At the moment I'm taking 15mg exemestane a week.
