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.
Man boobs, 'moobs' or enlarged male mammary glands - is natural progesterone a solution?
The medical term for 'man boobs' is gynecomastia which comes from the Greek meaning 'woman' + 'breasts'.
Although the cause is often deemed idiopathic (meaning it's not known), the majority of cases are caused by an imbalance of sex hormones. About 25% of cases fall into the idiopathic category.
The physical manifestation is breast enlargement, it normally occurs in both breasts but can sometimes be in one only, known as asymmetrical or unilateral gynecosmastia. Occasionally a secretion of milk can be present too. Man boobs can affect up to 60% of men, including infants and adolescents.
The breast can increase in size due to stimulation of the breast tissue and an increase in adipose (fat) cells. Man boobs can be tender or painful, the medical term is mastodynia, mastalgia or mammalgia.
