HCG for testicular preservation, and my estradiol is running high. I keep reading that chronic hCG desensitizes the LH receptor and that you should rotate hCG and hMG, one of each twice a week, to avoid that. Is that a real concern at preservation doses, or does it only apply to high fertility doses? And since hMG also has LH activity, would rotating actually bring E2 down, or is reducing the hCG dose the more sensible move? Trying to avoid adding an AI if I don't need one.
