Aromatase excess syndrome (AES or AEXS) is a rarely diagnosed genetic and endocrine syndrome which is characterized by an overexpression of aromatase, the enzyme responsible for the biosynthesis of the estrogen sex hormones from the androgens, in turn resulting in excessive levels of circulating estrogens and, accordingly, symptoms of hyperestrogenism.
Signs of hyperestrogenism may include heightened levels of one or more of the estrogen sex hormones (usually estradiol and/or estrone), lowered levels of follicle-stimulating hormone and/or luteinizing hormone (due to suppression of the hypothalamic–pituitary–gonadal axis by estrogen), and lowered levels of androgens such as testosterone (generally only relevant to males).

"Providers are encouraged to consult with their local lab(s) to obtain hormone level reference ranges for both 'male' and 'female' norms, [which can vary,] and then apply the correct range when interpreting results based on the current hormonal sex, rather than the sex of registration."

A study that used high- to very-high-dose oral estradiol to treat postmenopausal women with estrogen receptor-positive breast cancer found that mean steady-state estradiol levels in the 6 mg/day group were about 300 pg/mL and in the 30 mg/day group were about 2,400 pg/mL. [37]
Androgen replacement therapy (ART), often referred to as testosterone replacement therapy (TRT), is a form of hormone therapy in which androgens, often testosterone, are supplemented or replaced. It typically involves the administration of testosterone through injections, skin creams, patches, gels, pills, or subcutaneous pellets.
There are three different formulations of estrogen: estrone, estradiol, and estriol. [1] These are commonly referred to as E1, E2, and E3, following the listing stated prior. These three formulations have different functions in a women's life. Estradiol (E2) is seen in the reproductive time period. [1] Estriol (E3) is seen primarily during ...
Estradiol benzoate (EB), sold under the brand name Progynon-B among others, is an estrogen medication which is used in hormone therapy for menopausal symptoms and low estrogen levels in women, in hormone therapy for transgender women, and in the treatment of gynecological disorders. [8] [12] [13] It is also used in the treatment of prostate ...
Testosterone enanthate is used primarily in androgen replacement therapy. [4] [15] It is the most widely used form of testosterone in androgen replacement therapy. [4]The medication is specifically approved, in the United States, for the treatment of hypogonadism in men, delayed puberty in boys, and breast cancer in women. [16]
