Ideal testosterone to e2 ratio

anvil70 · Oct 7, 2024

Hey guys.

Many months ago when I first started with with a clinic I was told the ideal ratio of free testosterone to e2 is 1 to 1 - 1 to 2.

As of my last bloodwork my free test came back at 18.8 pg/mL and e2 came back at 34.9 pg/mL. During my consult i was told this was a ratio of 1 to 2. After lots of research im still confused on how this ratio was calculated, does anyone here have a formula?

Also is there an ideal ratio for total test to e2?
