Natural progesterone has been established as a safe and effective means of contraception. The foundational research on progesterone's contraceptive use was conducted by the late Dr. Katherina (Kittie) Dalton. She was a remarkably knowledgeable and compassionate individual who aided countless individuals through progesterone therapy. I have incorporated insights from her book, "PMS: The Essential Guide to Treatment Options."
It is widely recognized that individuals experiencing PMS typically do not encounter symptoms during pregnancy, particularly in the latter half. This phenomenon occurs because the placenta generates significant amounts of progesterone, which is vital for sustaining the pregnancy. Progesterone levels in the blood of pregnant women can be 40 to 50 times higher than those in women who are not pregnant. Nevertheless, some women may still experience PMS symptoms during the later stages of pregnancy, and these individuals are at an increased risk of developing pre-eclampsia (refer to Page 150 in Dr. Dalton's book). The term PMS was first introduced by Dr. Kittie Dalton in the 1950s.
During pregnancy, maintaining hormonal balance is essential for both the mother's and the baby's health. Progesterone, a crucial hormone for the maintenance of pregnancy, naturally rises to support the developing fetus. Given its importance, it's not surprising that some women contemplate using progesterone cream, particularly when dealing with hormonal imbalances or a history of miscarriages.
I want to begin by highlighting the risks associated with Contraceptives. They significantly contribute to difficulties in conceiving as they disrupt a woman's natural biological rhythm. Upon cessation, they can lead to substantial irregularities in the monthly cycle. All pharmaceutical contraceptives carry the potential for adverse effects. It’s crucial to allow sufficient time for synthetic estrogens and progestins to clear from the body before trying to conceive. An increasing number of young women are feeling desperate as they struggle to conceive after discontinuing birth control pills (BCP).
Contraception can frequently pose challenges for women, and those dealing with PMS face an especially tough period as well.
All birth control pills (BCP) include progestogens, which may also be referred to as progestagens or gestagens. This class of steroid hormones attaches to and activates the progesterone receptor (PR). While progesterone is the primary and most crucial progestogen in the body, progestins are synthetic versions of these hormones. These artificial progestogens can reduce natural blood progesterone levels, leading to an increase in the severity of PMS symptoms. It is advisable to avoid BCP at all costs.
* Sterilization increases PMS symptoms and should also be avoided no matter how popular this method is.
The intra-uterine device (IUD) is not recommended for women who have a history of pelvic infections or for young girls who have never been pregnant.
* Withdrawal is very unreliable not to mention stressful.
In addition to progesterone contraception, we have condoms, the diaphragm (often referred to as the Dutch Cap), and vasectomy as alternatives.
Progesterone is just as safe as a contraceptive as the IUD or BCP, but without the side effects PROVIDED it is used as follows:
It must be used before ovulation, generally half way through the follicular phase, and continued until bleeding. There is no harm in using it daily, but it can upset the cycle. The amount should be no less than 100mg per day, preferably 200mg per day. But, and it is big but, Stress drops progesterone levels, which could leave you unprotected. Extra precaution needs to be taken during stressful times. It is actually very effective at stopping ovulation, it works in the same way as the synthetic version, but without the side effects.
This is exactly how Dr Kittie Dalton advises to use progesterone as a contraceptive.
"Start on Day 8 of the cycle with a low dose of progesterone, and keep it up until menstruation or - for PMS sufferers - the day when you start on the bigger, anti-PMS dose. A daily dose of 100 mg (half a 200 mg suppository) or a 400 mg suppository are equally effective. (Many women who will use 400 mg of progesterone two to six times daily from ovulation onward prefer to take one 400 mg suppository in the follicular phase rather than having to get 200 mg suppositories as well").
As per Dr Kittie Dalton ....
A study of progesterone contraception in women with severe PMS showed 15 failures in 253 women who had used progesterone contraception for an average of 5.82 years. This means a failure rate of 2.66 per 100 women/years (women/years is a ratio that encompasses 100 women using a method of contraception for one year, 50 women using it for two, etc.), which compares favourably with the recognized failure rate of the condom of 14, diaphragm of 12, rhythm method 24, and intra-uterine device of 2.5 per 100 women/years.
However, some women find that by starting progesterone early they start bleeding at, or shortly after, ovulation. They should be advised to lower the dose of daily progesterone from Day 8 to 100 mg daily and start their usual higher dose of progesterone about two days after ovulation. If extra bleeding still occurs, then it is best to use a condom or diaphragm until the normal time of starting their course of progesterone. Should attacks of diarrhoea occur when using progesterone, then contraception cannot be guaranteed and alternative methods are advised. .....
Another common cause is PCOS. Please read my page on this syndrome and how it can be treated.
Progesterone plays a major role during the 2 weeks after ovulation, prior to the fertilised egg implanting in the uterus. It is also vital for maintaining pregnancy.
The first half of the monthly cycle is known as the follicular phase, and it can range from 7 days to 21 days. Progesterone is present in extremely small amounts, estrogen and follicle stimulating hormone (FSH) being the dominant hormones.
At the beginning of this phase, in response to FSH made by the pituitary gland, eggs start developing. Each egg is contained in a cyst called a Graafian follicle, which starts making estrogen, this in turn causes the egg to grow and mature. Estrogen also stimulates the endometrium (lining of the uterus) to grow and thicken. When 1 or 2 eggs are fully developed they rise to the surface of the ovary and appear as small 'blisters’.
When the egg has reached maturity, another hormone called lutenising hormone (LH) is released by the pituitary. Approximately 24 hours later this causes the Graafian follicle to rupture releasing an egg, known as ovulation. The follicle, which is now called the corpus luteum starts to produce progesterone for the next 14 days making progesterone the dominant hormone.
All women, irrespective of the length of their cycle, should start ovulating about 14 days before their next menstruation. If shorter, there is insufficient time for the endometrium to be readied for the embryo to implant, this is known as a defective luteal phase. If the corpus luteum does not make sufficient progesterone during these 14 days, it will result in a defective luteal phase. This seems to be a problem found in many women now and could well be due to the large amounts of estrogen in the environment.
At the beginning of the cycle, .i e. day 1 of bleeding, estradiol production either drops slightly or is flat for the first 2-4 days. It then rises slowly for the next 6-10 days, and then sharply for 2-5 days. This is the preovulatory peak, after which it drops.
During the 50 hours prior to the mid-cycle surge, estradiol, progesterone and another pituitary hormone secreted by the anterior pituitary gland called LH (luteinising hormone) begin rising, while FSH declines.
The cells forming the outer layer of the Graafian follicle are called thecal cells. LH is required for both the growth of preovulatory follicles and ovulation of the dominant follicle. Under the influence of LH they secrete testosterone. LH causes proliferation, differentiation, and secretion of androgens by the theca cells which surround the ovum, giving rise to androgen levels.
The androgens, notably androstendione, migrate from the theca cells to the granulosa cells where they are converted by the enzyme aromatase into estrogen, particularly estradiol. The theca cells also produce estradiol without the need for conversion. This rise in the androgens is responsible for the acne, oily skin, facial hair, loss of scalp hair etc. that some women experience.
12 hours prior to the mid-cycle surge, progesterone rises rapidly. This surge is produced by brain cells, and has nothing to do with the surge that occurs after ovulation. It is thought to initiate the LH surge which begins 12 hours after the progesterone surge. FSH rises again at the same time as LH. This preovulatory surge in progesterone is now known to be essential for the facilitation of feminine sexual behaviour too.
The surge of the gonadotrophins causes estradiol levels to rapidly fall, while progesterone continues to rise. The gonadotrophins plateau for about 14 hours after which they drop sharply.
Androstenedione (A) and testosterone (T) increase at a slow rate before the surge, rising faster when the mid-cycle surge begins. Then about 14 after initiation of the surge, they decline, but at a slower rate than estradiol. In spite of the significant increase in A and T, estradiol still drops sharply. It is thought that the rapid rise in progesterone may inhibit aromatase activity.
Progesterone is the pregnancy hormone. If there is too short an interval between ovulation and menstruation, then this is known as a defective luteal phase. A short interval of less than 12 days, means that progesterone level was not high enough resulting in an early miscarriage. This is due to the fertilised egg not embedding itself in the lining of the womb. This can be overcome by ensuring that there is sufficient progesterone after ovulation and until the placenta has started to produce its own progesterone. Progesterone therapy should be continued until the fourth month of pregnancy.
Taking temperature readings or using a mini microscope will help to check for ovulation, the mini microscope is more reliable, as temperature can vary from as little as 0.5 degrees to 5 degrees.
Saliva or vaginal mucus is used for the test, by dabbing a small amount on the end of the microscope. During the follicular phase, the pattern formed by the saliva/mucus is spotty, as ovulation draws near a fern like pattern starts emerging, becoming completely fern like when ovulation has occurred, returning to the spotty pattern almost immediately. For more information see Ovulation Microscope.
Normal oral body temperature in adult men and women ranges between 33.2-38.2°C (92-101°F). Typical average temperatures are 37.0°C (98.6°F).
In women it varies between the follicular and the luteal phase. During the follicular phase, i.e. from the first day of menstruation to ovulation, it ranges from 36.45 to 36.7°C (97.6 to 98.1°F).
During the 12-14 day luteal phase, i.e. after ovulation to menstruation, temperature increases by 0.15 - 0.45°C (0.2 - 0.9°F) due to the increased metabolic rate caused by rapidly rising levels of progesterone. Temperature ranges between 36.7 - 37.3°C (98.1 - 99.2°F) during the luteal phase, but drops down to follicular levels within a few days of bleeding.
One of the most important things to remember about conception is the life span of the sperm and ovum. The average life of the sperm appears to be 2 to 3 days, sometimes longer, but the ovum only lives 12 hours and in rare cases 24 hours.
Research points to a greater success in conception if intercourse takes place in the one to two days prior to ovulation, when the fern like pattern is almost complete. This allows time for the sperm to travel through the uterus and up the Fallopian tubes to meet the egg before it becomes over mature or it dies.
One of the problems with an over mature egg is it diminishes the chances of fertilisation, can result in a miscarriage or result in foetal abnormalities. The health of the future child is dependent on these factors. The nearer intercourse takes place to ovulation, the greater the chances of conception.
Some women have difficulty conceiving naturally and need in vitro fertilisation (IVF) will also need progesterone from the time of implantation until the placenta is producing enough progesterone to keep the embryo going. There are several different types of IVF treatment today, but they all need plenty of progesterone in the first few weeks.
If you have only started using progesterone at conception and experiencing terrible nausea or morning sickness you need to use nothing less than 400mg/12ml of progesterone cream per day. If severe, 800mg per day can be used. Never use the cream all at once - use morning and night - you can use during the day as well. If you use it all at once it will spike your progesterone level, levels should be kept as stable as possible. Stay on this amount for about a month or until your morning sickness starts to ease up or disappear. Once this happens, you can start to reduce the cream very slowly by 1/2ml at a time. Stay on the reduced amount for about 4 to 5 days, then reduce again by another 1/2ml and so on. If you reduce too fast and by too much your symptoms will return. Reduce until you find a level that suits you. Once you have found a level/dose you must stay on that dose throughout your pregnancy. If you discontinue you could have a miscarriage!!
Menstruation is not likely to return until after breastfeeding has finished, so if the mother is feeling well and plans to continue breastfeeding for many months, progesterone can be stopped after 2 months but, if the symptoms come back, the use of progesterone should be restarted. When progesterone was first isolated in 1934, researchers thought that its job in the body was to prepare the breasts for breastfeeding. Progesterone helps breastfeeding and mothers need not worry that it will upset their babies. 100-200mg is the recommended amount of progesterone to use.
Attention needs to be paid to your diet which as always, is so important to good health. A low carb diet is important, reducing carbohydrates and boosting protein intake can significantly improve the chance of conception - see references.
When a woman has had several miscarriages, she is naturally anxious that everything medically possible is done to ensure that she has a normal full-term pregnancy. Not surprisingly, she will often be given progesterone therapy to ensure this. There are many causes of miscarriages, including chromosomal defects, about which little can be done at present, but they may be due to anatomical abnormalities such as a lax cervix (opening to the womb), which can be stitched up until labour starts. There are also women who suffer from excessive vomiting and pregnancy symptoms immediately they become pregnant, and these are the ones most likely to benefit from progesterone given in a dose high enough to remove their symptoms. Among many patients treated over the years, Dr Dalton has treated two women who both had nine previous miscarriages and who were both given progesterone therapy, both were later delivered successfully of healthy babies at the City of London Maternity Hospital.
Bleeding in early pregnancy is always a worry. The patient is naturally wondering whether it is the end of the pregnancy or not. If bleeding is scanty and does not contain clots or foetal tissue, then with rest, there is a chance that all will be well and that a normal pregnancy will continue. This applies particularly if the bleeding comes at the expected time of the first missed period. If it is accompanied by excessive vomiting and early pregnancy symptoms, then again the patient will benefit from progesterone therapy in a dose sufficient to ease the symptoms. However, after the delivery the doctor is left wondering if the pregnancy would have continued even if progesterone had not been given.
Progesterone does help severe PMS, or as the doctors now prefer to call it, PMDD. It also stops post natal depression (PND) which is worse, and post natal psychosis which is the most severe form. High amounts of progesterone is needed for this. Dr Kittie Dalton would give 800mg per day for severe PMS/PND and 2400mg per day for post natal psychosis. It really is the wrong name for an illness which affects 10 percent of new mothers after their baby's birth, because depression is rarely the first symptom to appear and in many cases there is never any depression at all. Women who have suffered from PND can give much better descriptions of how they felt at the beginning of their illness, describing the sleeplessness and feeling:
It can be a horrifying experience for a partner to come face-to-face with the changed personality of the new mother who was previously calm and is now so anxious, previously alert and active but now dull and speechless, previously a successful career woman and now frightened to be left alone, previously carefree and now obsessional. Postnatal depression, and its more severe cousin puerperal psychosis, are hormonal diseases which have a lot in common with PMS and frequently turn into PMS as time passes. As a PND sufferer gradually improves, she will find that her symptoms get better after menstruation, only to get worse again before the next menstruation, and with further progress she gradually reaches the stage when there is absence of symptoms after menstruation but many of the symptoms premenstrually. At this point the illness has changed to PMS.
PND tends to occur in women who have suffered from severe PMS and in those who have already suffered from PND or puerperal psychosis after a previous pregnancy, and it may come unexpectedly after a perfectly normal pregnancy and delivery. It can be successfully avoided if arrangements are made during the pregnancy with the general practitioner, obstetrician and midwife. After the baby has been safely delivered, the mother should be given the first of seven daily progesterone injections: of 100 mg followed by 400 mg progesterone suppositories twice daily for the next two months or until normal menstruation returns. Menstruation is not likely to return until after breastfeeding has finished, so if the mother is feeling well and plans to continue breastfeeding for many months, the progesterone can be stopped after two months, if the symptoms come back, the progesterone should be restarted.
Once again, progesterone and Vitamin D3 plays a role and is most beneficial. Studies show that if low it could be the cause for those who may be at risk. One study finding progesterone was 'pathologically and statistically' lower. Serum allopregnanolone - a potent metabolite of progesterone - was found to be significantly lower too. The Th1 (inflammatory cytokines) and Th2 (anti-inflammatory cytokines) play a role. The number of Th1 cells and the ratio of Th1:Th2 in preeclampsia is significantly higher than in a normal pregnancy. Progesterone and vitamin D3 both increase levels of Th2.
However, a number of other factors have been found to play a role. Women with insulin resistance, high levels of malondialdehyde and homocysteine are at greater risk of developing preeclampsia. A lack of selenium and low levels of glutathione and other antioxidants increase the risk too.
If recurrent miscarriages, pre-term births or preeclampsia have occurred consider using 200-600mg Natpro progesterone cream per day. Many believe progesterone is not effective at preventing these, but the evidence points to far too little progesterone being used in the unsuccessful studies. Please see references.
Please read my page on Miscarriages.
Once pregnant the growing foetus is an extra burden on the mother, it is therefore vital that nutrition is taken. Please consider taking the following each day:
VITAMIN A - Do not take cod liver oil or any fish liver oil. The excessive vitamin A it contains prevents vitamin D3 from being absorbed and can become toxic. Take beta-carotene if deficient in vitamin A.
A big thank you to the late Dr Kittie Dalton who has helped so many women with PND and who are battling to conceive. Her knowledge has helped so many women today. I urge you to read her books:
Another book well worth reading was written by one of her patients. Nicola Owen, who's problems all started when she was fourteen and going through puberty, ended up in Holloway Prison for Women in the UK. Dr Dalton prescribed progesterone which corrected the psychosis, thereby helping her recover and obtain her release. It's now out of print, but Amazon do have second hand copies.
