This goal of this thread is to share knowledge about progesterone and NBE.
_________________________________________
Women and men produce progesterone daily, as follows:
Below are the reference ranges for oestradiol, testosterone and progesterone
Bio-Males
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.
Bio-Females
Premenopausal
Oestradiol 1.3 - 3.3 pg/ml
Progesterone 75 - 270 pg/ml
Postmenopausal
Oestradiol 0.5 - 1.7 pg/ml
Progesterone 12 - 100 pg/ml
Range for all ages
Testosterone 16 - 55 pg/ml
Progesterone is a precursor for testosterone, estradiol, cortisol, aldosterone, and allopregnenolone and allopregnanolone, etc.. Progesterone is broken down to Pregnanediol (inactive) after it is used. Progesterone is the precursor for testosterone in the testes. Increasing testosterone production requires increasing production of progesterone, its precursor. HCG can increase progesterone production in men. If the increase in progesterone leads to an increase in testosterone, this can have good or bad effects. Bad effects include slowing down the adrenal glands when one already has adrenal fatigue, excessive acne or hair loss, etc.
Progesterone is a precursor for estradiol. Progesterone also increases the number of estrogen receptors. Either one can lead to signs of excessive estrogen signaling (e.g. gynecomastia, aggressiveness, fatigue (from lowered thyroid hormone in response to increased estrogen signaling), loss of libido, etc. even if Estradiol is controlled (since the signal is stronger when there are more estrogen receptors).
Men produce estrogen (Estradiol) but in much lower amount than women. Men also produce progesterone, but about half the amount from that of females. Progesterone is made in men by the adrenal glands and testes. Progesterone is vital to good health in both women and men. It is the primary precursor of our adrenal cortical hormones and testosterone. The male hormone, testosterone, is an antagonist to estradiol (E2). It is made from progesterone. Men normally continue to produce relatively normal level of testosterone for their age and well into the seventies. Contrary to common perception, testosterone does not cause prostate cancer. Young men have high levels of testosterone and old men low levels. If testosterone were the cause of prostate cancer, young men would be dying of prostate cancer. Studies had shown that men with the highest level of testosterone have the least prostate enlargement. Conversely, men with the highest level of estrogen have enlarged prostates. Declining testosterone from aging, together with increasing level of estrogen, is the most likely reason for prostate enlargement and cancer in men.

Quote:-----------------------------------------------------------------------------
"The six most potent common herbs to bind progesterone receptors were oregano (Origanum vulgare), verbena (Verbena species), turmeric, thyme, red clover, and damania (Turnera difussa).
Herbs with *anti-progesterone* activity were red clover, licorice, goldenseal, pennyroyal (Mentha pulegium), nutmeg (Myristica fragrans), and mandrake (Podophyllum peltatum).
**Most progesterone-binding herbs were not active or were anti-progestogenic in the body (such as pennyroyal). **
Wild yam (Dioscoria villosa) increased progesterone receptor binding in 20-30% of women, but appeared to suppress progesterone. Researchers concluded that diosgenin, the yam compound used to synthesize progesterone, did not convert to progesterone in the body.

Licorice will not promote progesterone in the body. Although it binds with the progesterone receptor it is actually anti-progesteronic which means it will suppress progesterone.
The things I put ** around were to draw attention to them. This article confirms that most of the herbs that bind to progesterone receptors will actually lower progesterone in the body... which is too bad.
Now as far as the grapefruit, I will try to check it out and find out if it actually increases progesterone or suppresses it.
Thanks for providing the link. The world of herbs is a very complicated one, but if we all pitch in what we find I think we can come to some sort of unanimous truth about the NBE effect of herbs.
