Progesterone and Testosterone

[Guest guest]

I consume a lot of dairy products because, first, I like 'em, and

second, because I keep a high protein diet. A friend of mine - a

biologist who specializes in plants - raised the question whether the

progesterone, a natural hormone produced by cows and detected at some

level in milk, might interfere with the testosterone supplements I'm

currently taking. I Googled " progesterone " and found nothing

initially. The question is purely speculative and shouldn't be

construed as raising a concern. (Sometimes a simple question can cause

unreasonable panic, and I don't want that.) But I was wondering if

anyone with knowledge on the subject may have heard or read anything

about a connection or interaction.
