Progesterone for men
This is slightly "technical" explanation of how Natural Progesteron works and how it may reduce risk or prevent Prostate cancer. If you don't want to read the complicated bits just check the highlited ones, and then scroll down to the part about the diet recommendations.
As a man gets older testosterone is converted into di-hydrotestosterone (DHT), which some believe is the cause of benign prostatic hyperplasia (BPH) and cancer, but some do not.
Oestrogen levels also increase as a man gets older. Oestrogen is known to stimulate cell growth. Reading between the lines, because as yet, there is no definitive study done on this, it appears to be the increased oestrogen level which is the problem and not the two testosterones. As progesterone is a powerful counter-balance for estrogen, progesterone for men is essential.
If in fact testosterone were the culprit, then men aged ±22 would have the highest incidence of BPH (Benign Prostate Hypertrophy) and cancer, as testosterone levels are at their highest point in the early 20's, but of course they don't. From the early twenty's to the late twenty's testosterone makes it's greatest drop, thereafter it continues to decline, but at a slower rate.
BPH starts affecting a man in his fifties and interestingly oestradiol levels start climbing from the age of fifty and are at their highest point in men in their late 60's, but during the same period progesterone levels are declining. Progesterone for men becomes that much more important with age. 5-alpha reductase inhibitors such as finasteride are usually given to prevent the conversion of testosterone to DHT, but research has found that progesterone is a natural inhibitor of 5-alpha reductase.
Progesterone also down regulates the action of oestrogen if used in a sufficiently high dose. The endogenous oestrogen made by humans is now being supplemented by synthetic oestrogens found in the environment. They are now found in food, air, water, plastics, skin care products, no one can avoid them.
Some authorities speculate this is the cause of the increase in problems such as hyperplasia or cancers of any hormonally sensitive tissues, such as the prostate, endometrium, cervix and breasts.
So, despite often being, erroneously, thought of as a 'female' hormone progesterone for men is essential to preserve masculinity!
Below are the reference ranges for oestradiol, testosterone and progesterone for men...
- Oestradiol 0.5 - 2.2 pg/ml
- Progesterone 15 - 100 pg/ml
- Testosterone 44 - 148 pg/ml
As a reference point, the same hormones below are for women.
- Oestradiol 1.3 - 3.3 pg/ml
- Progesterone 75 - 270 pg/ml
- Oestradiol 0.5 - 1.7 pg/ml
- Progesterone 12 - 100 pg/ml
- Range for all ages
- Testosterone 16 - 55 pg/ml
Salivary hormone levels are often higher than serum (blood) levels when hormones are delivered topically (on the skin).
One of the most perplexing issues surrounding saliva testing is the odd phenomenon that topically delivered steroids cause a dramatic increase in salivary hormones without a concomitant increase in serum levels. For example, 30 mg topical progesterone supplementation results in an average rise in salivary levels from about 50 pg/ml (0.05 ng/ml) to 500 to 3000 pg/ml (0.5 to 3 ng/ml), a 10 to 60-fold increase.
This increase is proportionally even greater when progesterone is supplemented at 100 to 200 mg, a common topical dose used by many doctors, resulting in salivary progesterone levels rising to as high as 10,000 to 100,000 pg/ml (10-100 ng/ml). Under the same conditions, serum progesterone levels only increase about 4-fold, from about 0.5 to 2-3 ng/ml. The same disproportionate increase in salivary hormone levels is seen with topical delivery of all the other steroid hormones (eg. oestradiol, testosterone, DHEA. etc.)
Progesterone men and nutrition
More on nutrition below but when it comes to progesterone men should use 33-200mg/day, this equates to 1-6ml/day of Natpro.
Progesterone men and nutrients for the immune system:
Antioxidants are some of our most powerful defences. Take daily: 10,000-25,000 IU vitamin A; 1000-5000mg vitamin C; 500-1000mg bioflavonoids; 5-20mg Zinc; 100-1000 IU vitamin E; 200mcg selenium; 100mg Co enzyme Q10; 100mg Alpha-Lipoic Acid (ALA). Glutathione is our most powerful anti-oxidant and is vital for cellular defence. The liver makes it from the amino acids N-acetyl cysteine (NAC), L-glutamine/L-glutamic acid, and L-glycine, but as the limiting factor is cysteine take 1ic000-6000mg, (glutathione itself is not well absorbed); 4000-8000mg L-glutamine, the only amino acid which actively heals the intestines.
Progesterone men and antioxidants:
Green tea (catechins); raspberries, strawberries, blackberries, cranberries, walnuts, and pecans all contain ellagic acid, the greatest amount is found in raspberries; glucosinolates, potent inducers of Phase II enzymes, found in the brassica family, i.e. broccoli, cabbage, watercress etc; the spice turmeric contains curcumin, which has been found to stop pre-cancerous changes in the DNA; many plants contain flavonoids, which remove metal toxins and also protect the antioxidant vitamins; garlic is also a potent chelator of toxic minerals; silymarin, found in the herb milk thistle, is a powerful liver detoxifier.
To support adequate production of progesterone men should ensure the right diet: Food should be natural, unprocessed and if possible organic and include both protein and fibre, particularly that from green leaves.
Small frequent meals are often a help for blood sugar imbalances. After a large meal there is a temporary drop in the level of progesterone, due to an increased metabolic clearance rate of that hormone, so symptoms can become worse for a while.
As a substitute for sugar use erythritol, xylitol or stevia. Stevia is a natural extract from the plant Stevia rebaudiana, a member of the daisy family, native to Paraguay. The extract is 200-300 times sweeter than sugar, but has none of the drawbacks and does not affect blood sugar in any way. The fresh or dried leaves are easier to use and taste better.
Xylitol and erythritol are sugar alcohols, which look and taste like sugar, but are metabolized by the body at a much slower rate, they have respectively 2.4 and 0.0 calories per gram. They cannot be used by oral bacteria, so do not contribute to tooth decay. If used in large quantities xylitol can cause flatulence and have a laxative affect, unlike erythritol which is absorbed into the blood stream before reaching the large intestine.
Progesterone men and what to avoid:
Sugar and artificial sweeteners; all forms of processed foods, particularly those containing sugar; refined grains, particularly wheat; carbonated drinks, including the 'diet' drinks; fruit juices; biscuits; cakes; white breads; canned foods; sauces; sweets; large meals; all forms of oestrogen; oxidised fats, (ie margarine, refined oils, fried foods, in particular fried animal protein); pasteurised, homogenised milk; stimulants such as alcohol, coffee, black tea.
