Mean estradiol levels during 1 to 8 mg/day oral estradiol therapy alone or in combination with 100 to 200 mg/day spironolactone in transgender women. [ 3 ] Percent change in estradiol (E2), estrone (E1), LH, and FSH levels over a 24-hour period following a single dose of 2 mg oral estradiol in women.
The diagrams below take inter-cycle and inter-woman variability into account in displaying reference ranges for estradiol, progesterone, FSH and LH. Levels of estradiol (the main estrogen), progesterone, luteinizing hormone and follicle-stimulating hormone during the menstrual cycle. [88]
Follicle-stimulating hormone (FSH) is a gonadotropin, a glycoprotein polypeptide hormone. [1] FSH is synthesized and secreted by the gonadotropic cells of the anterior pituitary gland [ 2 ] and regulates the development, growth, pubertal maturation , and reproductive processes of the body.
Hormone levels with 2 mg oral micronized estradiol valerate tablets (Progynova, Schering) taken 3 or 4 times per day (6–8 mg/day total) sublingually (SL) in premenopausal women.

Menopause, also known as the climacteric, is the time when menstrual periods permanently stop, marking the end of the reproductive stage for the female human. [1] [6] [7] It typically occurs between the ages of 45 and 55, although the exact timing can vary. [8]
"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."

Follicle-stimulating hormone (FSH) is secreted by the anterior pituitary gland (Figure 2). FSH secretion begins to rise in the last few days of the previous menstrual cycle, [ 3 ] and is the highest and most important during the first week of the follicular phase [ 4 ] (Figure 1).
