The total endometrial proliferation dose of sublingual estradiol in women is 60 to 140 mg per cycle or 14 days and of sublingual estradiol benzoate in women is 60 to 180 mg per cycle or 14 days. [75]: 310 Both sublingual estradiol and sublingual estradiol benzoate have a persistence of estrogenic effect after a dose of only one day.
To perform this test blood samples are taken on day three of the menstrual cycle to obtain FSH and estradiol levels, then 100 mg of clomiphene citrate are given orally once a day on days 5 through 9 of the menstrual cycle, and finally on day 10 of the menstrual cycle a second blood sample is taken to measure FSH levels.

During the reproductive years of human females, levels of estradiol are somewhat higher than that of estrone, except during the early follicular phase of the menstrual cycle; thus, estradiol may be considered the predominant estrogen during human female reproductive years in terms of absolute serum levels and estrogenic activity.
Two or three days before LH levels begin to increase, [7] usually by day seven of the cycle, [8] one (or occasionally two) of the recruited follicles has emerged as dominant. Many endocrinologists believe that the estrogen secretion of the dominant follicle has increased to a level that GnRH production is suppressed, which lowers the levels of ...
Estradiol is an estrogen, or an agonist of the nuclear estrogen receptors (ERs), the estrogen receptor alpha (ERα) and the estrogen receptor beta (ERβ). [1] [2] [6] In one study, the EC 50 Tooltip half-maximal effective concentration value of estradiol for the human ERα was 50 pM (0.05 nM) and for the human ERβ was 200 pM (0.2 nM).
Ovulation occurs ~35 hours after the beginning of the LH surge or ~10 hours following the LH surge. Several days after ovulation, the increasing amount of estrogen produced by the corpus luteum may cause one or two days of fertile cervical mucus, lower basal body temperatures, or both. This is known as a "secondary estrogen surge". [4]
Considering the menstrual cycle as a 28-day cycle, hormonal oral contraceptives are available in packages of 21, 28, or 91 tablets. [29] These pills have typically undergone unit dose optimisation so that they follow the administration pattern of once daily, every day or almost every day on a regular basis. [29]
