The article then moves on to progesterone, which may oppose the negative effects of oestradiol. A study of 358 postmenopausal women found that the risk of uterine tissue growth was only 6% when oestrogen (this was conventional HRT) and progesterone were combined, compared with a 64% risk when only oestrogen was taken. By "conventional HRT", I mean a horse's oestrogen. A Belgian study mentioned found that progesterone could also reduce the risk of breast tissue growth. Additionally, the use of testosterone may protect against the unwanted effects of oestrogen replacement, though the studies discussed showed a lesser effect of testosterone compared to progesterone. Read more of my thoughts on testosterone here. DHEA replacement produced mixed results, though it did show benefit as a cream for skin health.
So, unlike some naturopaths, I do support the use of bioidentical HRT if herbal and nutritional support do not give the desired results, or if it's just your personal choice. However, I would recommend liver support to maintain healthy hormone metabolism, and I recommend that you always arrange a formal consultation with someone who can prescribe these hormones first, instead of self-medicating.
