Low values ​​are seen in ovarian dysfunction, premature ovarian failure, and Sheehan's syndrome.

It can supplement the deficiency of 17-β estradiol secreted by female ovaries, while avoiding the side effects caused by oral administration (breast pain, weight gain, high blood pressure, gallstones and abnormal liver function, etc.). Estrogen can stimulate cells to synthesize DNA, RNA and various proteins in corresponding tissues.
