The luteal phase is defined by the secretion and elevated levels of progesterone, which prepares the uterine lining for potential pregnancy as described in [1], [2], and [3]. Furthermore, the mid-luteal phase is specifically characterized by peak progesterone production rates [4] and serum concentrations [5].

measurementThe daily production rate of progesterone in women is 1 mg during the early follicular phase, 4 mg during the preovulatory phase, and 25 mg during the mid-luteal phase.
procedureProgesterone decreases the biologic activity of estradiol on the endometrium during the luteal phase by decreasing the concentration of estradiol receptors, increasing the enzymatic activity of 17β-hydroxysteroid dehydrogenase type II (which converts estradiol to estrone), and increasing the activity of estrone sulfotransferase.
claimAfter induction of ovulation, the amount of progesterone secreted and the length of the luteal phase depend on repeated LH injections.
claimDuring the luteal phase, rising progesterone levels cause a decrease in acidophilic vaginal epithelial cells, which are replaced by an increasing number of leukocytes.
claimThe secretion of progesterone and estradiol during the luteal phase is episodic and correlates closely with pulses of Luteinizing hormone (LH) secretion.
claimPlasma levels of deoxycorticosterone increase during the luteal phase due to extra-adrenal 21-hydroxylation of progesterone.

claimThe follicular phase is primarily characterized by the rise of follicle-stimulating hormone (FSH) and estrogen to develop an egg, whereas the luteal phase is characterized by the rise of progesterone to prepare for pregnancy.
claimIf pregnancy does not occur during the luteal phase, progesterone levels drop, causing the menstrual cycle to restart.
claimAn estrogen and progesterone graph typically shows two peaks: estrogen peaks before ovulation, and progesterone peaks during the mid-luteal phase.
claimThe luteal phase occurs during days 16-28 of the menstrual cycle and is characterized by progesterone preparing the uterus for pregnancy.
claimDuring the luteal phase, progesterone levels continue to rise, which helps thicken the uterine lining.

claimSome individuals may experience anxiety during the luteal phase due to elevated estrogen and progesterone levels in the first half of the phase and dropped levels in the second half, which may affect sleep or cause insomnia.
