lu·te·al phase

that portion of the menstrual cycle extending from the time of formation of the corpus luteum to the onset of menses, usually 14 days long; short luteal phase, a period of 10 days or fewer between ovulation and the onset of menses, frequently associated with infertility.

luteal phase

the third phase of the human menstrual cycle, when the ovarian follicle that has recently discharged an ovum ruptures and transforms into the corpus luteum, which secretes progesterone. Progesterone acts on the endometrium to build up tissue with a supply of blood for nourishment of the potential embryo. If fertilization and conception do not take place, the estrogen level falls and the menstrual phase begins.

lu·te·al phase

(lū'tē-ăl fāz)
That portion of the menstrual cycle extending from the time of formation of the corpus luteum to the onset of menses, usually 14 days in length; short luteal phase, a period of 10 days or fewer between ovulation and the onset of menses, frequently associated with infertility.

luteal phase

The phase of the menstrual cycle following ovulation when the CORPUS LUTEUM is active in the ovary.

luteal phase

the phase of the OESTRUS CYCLE in which the CORPUS LUTEUM forms in the ovary. Secretion of PROGESTERONE takes place followed by the development of uterine glands and a fall off in OESTROGEN secretion.

luteal

pertaining to or having the properties of the corpus luteum or its active principle.

luteal cyst
includes cystic corpora lutea, which are not evidence of ovarian malfunction, and luteinized cysts, which are usually anovulatory. The former can be identified by the presence of a palpable ovulation papilla. Animals with luteal cysts tend to be anestrus due to progesterone secreted by the cysts. See also luteal cyst.
luteal phase
the stage of the estrous cycle during which the effect of the corpus luteum dominates and the cow is anestrous because of the high levels of progesterone in the blood.

As shown in Figure 1, the plasma progesterone concentrations on d-19 of the pregnant cows significantly decreased from those of luteal phase cows on d-19, suggesting the significant deviation occurred at the time of expected onset of luteolysis.
Plasma inhibin, FSH and estradiol concentration were lowest during the mid luteal phase, increased through the late luteal phase to a maximum concentration during the perioestrous phase.
For example, if one researcher's premenstrual phase is another's postovulatory phase, and yet still another's mid or late luteal phase, and if all three researchers report peaks in desire during their respective phases, unwary readers of this literature may conclude that the data are contradictory--that sexual desire reached its maximum height in three separate phases -- when, in fact, it peaked in but one phase.
Prior notes that short luteal phases or anovulatory cycles frequently go undetected because they do not change the amount of blood flow or the total length of a woman's cycle.
Several meta-analyses as well as a recent large prospective, randomized trial have compared the efficacy of Crinone and intramuscular progesterone (IMP for luteal phase support during in vitro fertilization (IVF) and reported similar pregnancy rates and IVF cycle outcomes.
The overall mean progesterone concentrations in the HP goats were not significantly higher than in the PP goats during the luteal phase (1.
Key Findings from the Roundtable -- Luteal phase support should be initiated on the evening of or the day after oocyte retrieval.
We examined the relationship of 1976 serum TCDD levels with ultrasound-detected ovarian follicles among 96 women in the menstrual follicular phase and serum hormone levels (estradiol, progesterone) among 129 women in the menstrual luteal phase at follow-up.
The luteal phase was defined as the time from 4 to 10 days after the day on which LH and FSH were highest.
The ovaries secrete this sex hormone during the menstrual cycle's luteal phase -- the 13 days preceding menstruation, when PMS symptoms typically erupt.
5) Based on these metabolic considerations, women would want to watch their starch/sugar intake during the luteal phase and minimize more catabolic forms of exercise.
