Levels of estradiol in premenopausal women are highly variable throughout the menstrual cycle and reference ranges widely vary from source to source. [62] Estradiol levels are minimal and according to most laboratories range from 20 to 80 pg/mL during the early to mid follicular phase (or the first week of the menstrual cycle, also known as ...
High estrogen is typically defined as “levels exceeding the normal range” for a specific age and menstrual phase, often accompanied by other symptoms (more on this soon), she says ...
Quantitatively, estrogens circulate at lower levels than androgens in both men and women. [6] While estrogen levels are significantly lower in males than in females, estrogens nevertheless have important physiological roles in males. [7] Like all steroid hormones, estrogens readily diffuse across the cell membrane.
Blood for the test must be taken in the morning hours, when levels are highest, as levels can drop by as much as 13% during the day and all normal reference ranges are based on morning levels. [9] [10] Normal total testosterone levels depend on the man's age but generally range from 240 to 950 ng/dL (nanograms per deciliter) or 8.3–32.9 nmol ...
Similarly, a “normal” estrogen level ranges from 30 to 300, and there’s no data that says being closer to 30 or closer to 300 is better for you because every person reacts differently to ...
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).

Estradiol levels with 50 to 100 μg/day transdermal estradiol patches applied to the forearm and to the scrotum in a crossover study in 2 men with prostate cancer. [204] In 35 men treated continuously with one 100 μg/day estradiol patch scrotally, the mean estradiol level was ~500 pg/mL (range ~125–1,200 pg/mL). [204]
