The word “body identical hormones” has been introduced to define exact duplicates of hormones which are usually synthesized by the human ovary and adrenal glands i.e., estradiol, estriol, estrone, progesterone, DHEA and testosterone.
These hormones are seen as relatively safer hormones due its similarity of structure and behaviour to our own body hormones. Of these hormones, the progesterone body identical hormone is the most important.
Micronised progesterone has been shown not to have an effect on the lipid and glucose metabolism and on vascular tone, fluid retention, weight gain and acne.
The use of body identical hormones such as the oral and transdermal estradiol and oral micronised progesterone does not increase the risk of cardiovascular disease, stroke, VTE and breast cancer.
