Estrogens are mainly responsible for the maintenance and development of a woman’s reproductive system and their secondary sexual problems. The primary intracellular human estrogen is called estradiol, which is known to be stronger than estrone and estriol at the receptor level. In a woman’s normal menstrual cycle, around 70 to 500 mcg of estradiol is secreted, but during the postmenopausal stage, estrone and estrone sulfate becomes the most abundant. Estradiol is transformed into estrone, and both can turn into estriol, which is a primary metabolite. There are no studies done on formal drug interactions with Estring.
