Phallas atrophy akin to ambiguios genitalia happened to me when T was 45 and E2 was 250 (ratio was aprox 1:5.5)
Phallus returned to normal size when T was lowered to 28, and E2 was 99 (ratio was aprox 1:3.5)
Those figures were IM injections to patches, but the odd thing was if i missed a nightly 7.5mg of patches, the a morning erection was there to great me.
Breast lumps appeared on Im when the E@ was to high, but disappeared when i lowered the E2
On IM for me, there were no erections.
