Re progesterone converting to other hormones:
I think this may depend on where you are in peri or menopause and also what your individual baseline levels of hormones and enzymes are. Some people may be more sensitive than others.
Every time I have used either vaginal or sublingual progesterone (both avoid digestion and liver metabolism on first pass thru body), my total testosterone blood level goes up to highest normal range and sometimes higher and the free testosterone increases some also. It takes forever for it to go down (months). If I take it orally at 100mg, my testosterone level stays in mid to lower normal range for my age. I don't like it to be high because I don't like how it makes me feel, makes my bladder worse, and I get acne spots mostly on the buttock area. Taking it orally at 200mg causes testosterone to rise also, but not as much as vaginal or SL dose. I don't cycle so I use prog 25 days/mo.
So...I am a believer in this. However, it has never shown to change my estrogen level appreciably...maybe because I am taking estrogen too via patch??
