See the diagram in which 17α-hydroxylase and 17,20-lyase are located. Inhibiting this enzyme so early in the biosynthesis of androgens is real game change.
Theres another option though, and that's by elevating SHBG (sex hormone binding globulin). And SHBG's job is to transport hormones to target tissues. So, if Estradiol is elevated in SHBG (around 120 ng/dL) time is stuck in SHBG unable to transport. SHBG originates in the liver.
High levels of T and DHT are effective in displacing E2 (estradiol) from target tissues. When this inverse relationship of high T/DHT to Estradiol is present you can kiss feminizing...and breast growth because DHT has a 4x affinity over Estradiol in SHBG.
Green Tea raises estradiol in SHBG...now that's something to get overly excited about?.
Higher body temp (like over 99⁰) raises SHBG and thus inhibits DHT.

High insulin lowers SHBG, that'll raise testosterone and go in the wrong direction.
cAMP (cyclic adenosine monophosphate) which are second messengers will increase SHBG, I know, it's technical.
Things like metformin will increase SHBG. We've known about SHBG since 2015 here at BN. Check out this thread in the Ladies forum, it's full of good stuff. We even had a scientist (Clelia) join in with the research. Something I found out was that the receptors cells are made up of palmitic acid, and how cool is that?. This means receptor cells are fat lovin.

I'm still working on a list of what raises SHBG. But think about this, if we knew how to raise SHBG...it may mean taking less NBE/HRT.
