On the plus side .. My T levels seem to be looking good.

Testosterone has dropped from 15.7 to 0.4
Free T has dropped from 72 to 1, from my last readings in April.

The doctor sugests I cut back on the black cohosh !

Hi Janet,


Soy (phytoestrogens, that includes PM) coffee, sodas, etc lower iron absorption levels, just supplement with an iron supplement as suggested.

The 15.7 to .04 (reported in nnmoL) translates to 452 ng/dl to 115 ng/dl. The free T values doesn't make sense. Normal free T for males: 9-30 ng/dL, can you verify please. The link below could help calculate Free T

How much black cohosh have you been taking?, are you taking it with anything else. Like I said before, black cohosh inhibits (suppresses) the LH (lutenizing hormone) which prevents the HPA (hypothalamus pituitary axis) signaling the testes (leydig cells) to produce testosterone. Effective approach, accept if combined with an aromatase to facilitate FSH (follicle stimulating hormone) synthesis with E2 (or phytoestrogen) has a potential of a one-two punch. (well......that's my new working theory anyways).
