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."

E2 can protect the heart and individual cardiac myocytes from injuries related to ischemia. After a heart attack or long periods of hypertension, E2 inhibits the adverse effects of pathologic remodeling of the heart. [40] During pregnancy, high levels of estrogens, namely estradiol, increase coagulation and the risk of venous thromboembolism
Elsewhere in the world, oral estradiol valerate is similarly approved for the treatment of symptoms associated with menopause or hypoestrogenism due to castration in women. [14] Such symptoms may include hot flashes, outbreaks of sweat , sleep disturbances , depressive moods , irritability , headaches , and dizziness .
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.
Estrogens may be used in treatment of infertility in women when there is a need to develop sperm-friendly cervical mucus or an appropriate uterine lining. [65] [66] It is also commonly used during in vitro fertilization (IVF). Estrogen helps maintain the endometrial lining of the uterus and help prepare for pregnancy.
One study concluded that long-term testosterone replacement therapy (TRT) in middle-aged men with late-onset hypogonadism (LOH) and metabolic syndrome (MS) led to a significant increase in both vertebral and femoral bone mineral density (BMD) after 36 months of treatment, as measured by dual-energy x-ray absorptiometry. The TRT treatment was ...
