Luteal Phase (Definition)

The luteal phase (or secretory phase) is the latter phase of the menstrual cycle (in humans and a few other animals) or the estrous cycle (in other placental mammals). It begins with the formation of the corpus luteum and ends in either pregnancy or luteolysis. The main hormone associated with this stage is progesterone, which is significantly higher ...Read more

What is the normal range of the pg/e2 ratio during the luteal phase (ideally 20th or 21st day of the cycle)? Thank you.

What is the normal range of the pg/e2 ratio during the luteal phase (ideally 20th or 21st day of the cycle)? Thank you.

Hard number to find: But a website called Rocky Mountain Analytical Lab had this to say: 95% of regularly cycling women not on hormones have a Pg to E2 ratio of between 23 and 57 (sampled one week prior to onset of menses). Unfortunately, because of the variability in absorption from person to person, the Pg to E2 ratio is not useful when women are on topical progesterone and/or estrogen. ...Read more

Is it normal to have small brown spotting on and off during the luteal phase? (Not enough for pantyliner) Or should I be concerned?

If this is a recurring problem you should be evaluated. Infections & hormonal changes can cause spotting. If there is a concern for pregnancy then do a home pregnancy test. There are many options available to help regulate the menstrual cycle. Schedule a visit. ...Read more

I know progesterone dominates the luteal phase, but is it possible to also have estrogen surges during this time? Particul. Round 2/3 days past O?

I know progesterone dominates the luteal phase, but is it possible to also have estrogen surges during this time? Particul. Round 2/3 days past O?

Yes: Yes, it is not uncommon to have a "secondary estrogen surge" a few days after ovulation. The estrogen surge is not as significant as the Progesterone surge, but it is still responsible for creating fertile cervical mucous and lowering the basal body temperature. Once those two hormones drop off in levels, your lining sheds and you have your period-unless you become pregnant during the luteal phase ...Read more

Is it possible to have estrogen surges during the luteal phase? Particularly about 3 days after ovulation?

Yes: There is commonly a "secondary" estrogen surge during the luteal phase produced by the corpus luteum, although Progesterone is the larger surge during this time. This secondary estrogen phase is responsible for the one to two days of "fertile" cervical secretions and lower basal body temperatures and this tends to occur several days after ovulation. ...Read more

Medical foods: Yes, we do have experience using biologically active B vitamins, and even Vitamin D supplements. Since these items require prescriptions, and are not available in your "vitamin store", you need to discuss with your physician. Also, may help to explore your emotional state at time of hormonal shifts, as this can contribute to cognitive change. ...Read more

Low progesterone during luteal phase, FSH, LH and estradiol normal. Why? I have an history of anorexia..

Relevance?: Do you have regular periods? If so then the level of your progesterone during the luteal phase is not clinically useful information. If you are trying to get pregnant then perhaps your progesterone was checked to determine if ovulation occurred or not. If you are not ovulating then there are certain medications which can be given to induce ovulation ...Read more

How do I lengthen luteal phase?

Luteal phase: Well realistically, you probably can't. Why do you think your luteal phase needs lengthening? Some women get a longer luteal phase when on clomiphene, though it's not consistent. If you have a documented luteal-phase defect and worried about miscarriage, supplemental Progesterone sometimes helps. ...Read more

How will gyno know what my luteal phase is?

2nd half of cycle: The menstrual cycle is divided into four sections. In order, the follicular, ovulatory, luteal, and menstrual phases. At ovulation, approx. Day 14-15, the egg leaves the follicle. The luteal phase follows and typically lasts 14 days - the last 14 days before menses starts. Looking at a temp. Chart, or testing with an ovulation kit are two ways to infer the luteal phase. ...Read more

How does a woman correct a luteal phase defect?

Two ways: Luteal phase defect (lpd) implies a low Progesterone (p4) after ovulation. The diagnosis is controversial because measuring p4 is easy but interpreting the results is tricky. We have several normal levels accepted plus the use of an endometrial biopsy to indirectly assess p4 levels. If we believe the test results then we give p4 supplements or stimulate the ovary follicles to make more p4. ...Read more

How long can a luteal phase be in a 28 day cycle?

Can vary some.: Normal is 14 days, but in various ovulation disorders the luteal phase may be shortened. In advanced reproductive age, >35, the luteal phase might shorten some as well. The most variability though is in the follicular phase with age. Cycles closer than 27 days indicate ovarian aging. Good luck. ...Read more

The lactational amenorrhea method of birth control works primarily by preventing ovulation, but is also known to cause lpd. ...Read more
