Progesterone for PMS Part Two

Progesterone for PMS, and irregular menstrual cycles. Part Two
For over a million years, now, estrogen and progesterone has been key players in the female menstrual cycle, ovulation and fertility.  Left Image: Iconic 1966 theatrical poster of Raquel Welch in One Million Years BC. later featured in the Shawshank Redemption covering the escape tunnel.

Understanding the Normal Menstrual Cycle – Hormone Charts

The chart below from college level biology class, showing the idealized normal menstrual cycle.Dysfunctional uterine bleedingEstrogen and Progesterone

To understand progesterone and estrogen,  one must review the above chart showing the major events of the menstrual cycle.  Estrogen and progesterone are natural human hormones produced in harmony by the ovary. Estrogen is produced throughout most of the month, from days 5-26 with a peak just before ovulation (day 11) and another peak around day 19.

The Corpus Luteum

Progesterone is produced the last two weeks of the monthly cycle by the corpus luteum,  a specialized ovarian structure, representing the remnant of the ovulatory follicle after ovulation.  During ovulation, the egg (aka ovum, oocyte) is expelled from the ovarian follicle, and starts its long journey down the fallopian tube to the endometrial cavity where fertilization and  implantation may occur (aka ovulation).  Ovulation usually occurs on day 11 (vertical dotted line on chart), so progesterone levels start rising on day 12, peaking on day 19-20 or so.

Sudden Decline in Hormone Levels Leads to Bleeding

Both progesterone and estrogen levels decline suddenly around day 26 of the menstrual cycle.  This sudden drop in hormone levels initiates menstrual bleeding, the endometrial lining has lost hormonal support and sloughs off (aka menstrual bleeding).  Left image shows microscopic view of ovary and corpus luteum courtesy of UNSW Embryology.

Idealized Normal Menstrual Cycle

The above schematic diagram  shows the idealized menstrual cycle in the normal female.  Firstly, look at the top row.  The yellow do-nut like-structure  is the corpus luteum in the ovary which makes progesterone.  The next row down is body temperature which spikes up at the time of ovulation around day 11.  The vertical dotted line represents ovulation around day 11.  The next row down we see that FSH and LH spike at the time of ovulation.  These are pituitary hormones.  FSH is follicle stimulating hormone, and LH is leutinizing hormone. The next row down, we see charts of serum estrogen (yellow) and progesterone (purple).  Estrogen spikes just before ovulation, and then has a second peak around day 19.  Progesterone starts rising after ovulation, peaks around day 19 and then falls off around day 26.  The bottom row shows a schematic of the endometrial lining which thickens with hormonal stimulation, and then sloughs off as hormone levels drop off at day 26.

Anovulation, Estreogen Dominance and Menstrual Irregularities

The chart shows a normal ovulatory cycle.  What happens if ovulation does not occur?  This is called anovulation, a common problem in young women. in which the ovum is not expelled, no corpus luteum is formed, and no progesterone is produced.  Without ovulation, menstrual bleeding becomes irregular, and the cycle length is variable.   This leads to a condition known as “estrogen dominance” in which body tissues respond to estrogenic stimulation without progesterone to counter act the estrogen..

PMS – PreMenstrual Syndrome – Estrogen Dominance

Estrogen causes fluid retention and breast tissue stimulation.  In the absence of enough progesterone to counter balance the estrogen,  the patient may experience bloating, breast enlargement and tenderness, and fluid retention.  Estrogen also causes psycho-stimulation, so the patient may complain of insomnia and mood disorders, migraine headaches etc..   As estrogen levels drop, the serum binding protein levels also drop, thus liberating testosterone to cause acne, oily skin and aggressive, “snappy” behavior.

In some cases, ovulation occurs , yet progesterone production is insufficient to balance  the massive amounts of estrogen.  Similarly these patients suffer from “estrogen dominance” and a similar symptom complex also called “PMS”. premenstrual syndrome.

Treatment for PMS and Irregular Menstrual Cycles

Since progesterone is the missing or deficient element in the PMS syndrome, it would be logical to assume providing progesterone in the form of creams or capsules would benefit the patient.  In fact, many doctors and patients report dramatic resolution of PMS symptoms with progesterone capsules and creams.  Of course, an annual pelvic exam by the local gynecologist as well as pelvic sonogram is warranted for pre-menopausal women prior to treatment with natural progesterone.   Although we will typically perform laboratory testing of hormone levels on day 19 of the menstrual cycle, this type of lab testing is not required by mainstream medicine, and in fact rarely done for treatment of PMS or irregular menstrual bleeding.  For more on this, see my article on the importance of the pelvic sonogram.

Still Not Accepted by Mainstream Medicine

Although progesterone is an FDA approved drug, mainstream medicine has yet to accept bioidentical natural human progesterone as a treatment for PMS and irregular menstrual cycles. Instead, mainstream medicine relies on synthetic forms of progesterone called “progestins” such as medroxyprogesteron (Provera) which was shown to cause breast cancer and heart disease in the ill fated Women’s Health Initiative Study.  Why hasn’t mainstream medicine accepted progesterone as a valid treatment for PMS?  This is explained by the “War Against Natural Medicine”.

The War Against Natural Medicine

In my first book,  Natural medicine 101, I delved into the reasons for the information war between natural medicine and mainstream medicine.  In short, mainstream medicine is dominated by the drug industry whose profits are dependent on the patented drug system.  A patented drug is a natural molecule whose chemical structure has been altered in order to obtain a patent.  Molecular structures naturally occurring in the human body or in nature by definition cannot be patented, and are therefore of no interest to the drug industry.  Rather, these natural substances such as progesterone represent economic competition to the patented counterparts.  That is why progesterone has not taken its rightful place in mainstream medicine treatment of PMS.  Left Image courtesy of SheKnows Left image courtesy of Dysfunctional uterine bleeding.

Removal of the ovaries has long been used to prevent endogenous progesterone production as a treatment for breast cancer. Recent studies confirm that progesterones cause more breast cancer than oestrogens. Progesterone is also potentially teratogenic.

Oral administration of micronized progesterone: a review and more experience.
McAuley JW1, Kroboth FJ, Kroboth PD.
Historically, oral progesterone has been regarded clinically ineffective because of its poor absorption and rapid clearance. Recent evidence suggests that an oral micronized form of natural progesterone is readily absorbed, produces luteal phase serum concentrations, provokes an end-organ response, and has no detrimental effect on the lipoprotein profile. Thus it is considered by many to be an attractive alternative to synthetic progestin. We evaluated the effects of a single oral dose of micronized progesterone 300 mg in eight healthy postmenopausal women. The maximum serum concentration ranged from 15.72-625.98 ng/ml.
Efficacy of oral micronized progesterone in the treatment of luteal phase defects.
Frishman GN1, Klock SC, Luciano AA, Nulsen JC.
Vaginal progesterone suppositories are an accepted treatment for infertility attributed to luteal phase defects. Although oral micronized progesterone may be preferable to suppositories for many patients, there are no studies on its use for patients with luteal phase defects. This study evaluated the efficacy of oral micronized progesterone for the treatment of luteal phase defects.
STUDY DESIGN:  Seven women with luteal phase defects previously corrected by vaginal suppositories were administered oral micronized progesterone (200 mg by mouth three times a day). Endometrial biopsies were performed to evaluate treatment efficacy. Questionnaires were used to assess side effects, including sedation.
RESULTS:  On oral micronized progesterone, all patients had in-phase endometrial biopsies. Despite complaints of drowsiness, the majority of patients preferred the oral formulation over the vaginal route of administration.
CONCLUSION:  We conclude that oral micronized progesterone is efficacious in the treatment of luteal phase defects.

Objective: To integrate and evaluate the pharmacokinetic, endocrine, and clinical effects of micronized progesterone formulations.

Design: Published articles concerning the pharmacokinetics of orally administered progesterone and the potential clinical uses of oral micronized progesterone were reviewed. Results concerning their use for secondary amenorrhea, premenopausal bleeding disorders, luteal phase dysfunction, termination of premature labor, hormone replacement therapy, and premenopausal syndrome are summarized. Critical issues to be resolved through ongoing preclinical and clinical research are highlighted.

Result(s): Because of the enhanced bioavailability of oral micronized progesterone, the compound may be useful for a variety of therapeutic indications. Oral micronized progesterone is available in France, and a formulation recently has been approved in the United States for the treatment of secondary amenorrhea and postmenopausal hormone replacement therapy. A large body of evidence, including the Postmenopausal Estrogen/Progestin Interventions study, suggests that the use of a combination of estrogen and oral micronized progesterone is optimal for long-term hormone replacement therapy. There also are data indicating that oral micronized progesterone could be of potential use for the treatment of premenopausal bleeding disorders, luteal phase disorders, and premature labor.

Conclusion(s): Oral micronized progesterone has widespread clinical potential, particularly for the treatment of secondary amenorrhea and dysfunctional premenopausal bleeding, and as a component of postmenopausal hormone replacement therapy.

In summary, oral micronized progesterone has the potential for widespread clinical utility. For indications in which oral delivery of the synthetic progestins currently are used, the theoretic benefits of oral delivery of the natural form of the hormone are obvious. In addition to the decreased potential for adverse effects, there are clear advantages in convenience, cost, compliance, and quality of life.

Progesterone and the premenstrual syndrome: a double blind crossover trial.
Dennerstein L, Spencer-Gardner C, Gotts G, Brown JB, Smith MA, Burrows GD.
A double blind, randomised, crossover trial of oral micronised progesterone (two months) and placebo (two months) was conducted to determine whether progesterone alleviated premenstrual complaints. Twenty three women were interviewed premenstrually before treatment and in each month of treatment. They completed Moos’s menstrual distress questionnaire, Beck et al’s depression inventory, Spielberger et al’s state anxiety inventory, the mood adjective checklist, and a daily symptom record. Analyses of data found an overall beneficial effect of being treated for all variables except restlessness, positive moods, and interest in sex. Maximum improvement occurred in the first month of treatment with progesterone. Nevertheless, an appreciably beneficial effect of progesterone over placebo for mood and some physical symptoms was identifiable after both one and two months of treatment. Further studies are needed to determine the optimum duration of treatment.

Heavy Menstrual Bleeding (Menorrhagia) Christiane Northrup, M.D.
Although I prefer to try natural progesterone first, if that doesn’t work, a strong synthetic progestin such as medroxyprogesterone acetate (Provera) can help. (This is the only circumstance in which I recommend the synthetic.) T – See more at:

Treatment of Premenstrual Syndrome
Premenstrual Syndrome is a condition of estrogen dominance-progesterone deficiency. It occurs in the two weeks before the period and goes away when the period is over. 150 emotional and physical symptoms can occur. Symptoms may include headaches, migraines, menstrual cramps, depression, irritability, fatigue, emotional outbursts, low blood sugar, rage, out of control behavior, dizziness, decreased resistance to infection and epileptic seizures. An underactive thyroid is commonly an underlying disorder that is present.
Patients can become symptom-free on natural progesterone therapy. If the patient is hypothyroid, treatment involves thyroid supplements.
