I've never found any information that suggests that Wild Yam is supposed to act as an androgen inhibitor. The only claims (for feminization purposes) are that it contains progesterone, which the body might convert into estrogen. However, I've also found statements like the one below, from
http://www.healthwell.com:
"Contrary to popular claims, wild yam roots do not contain and are not converted into progesterone or dehydroepiandrosterone (DHEA) in the body. Pharmaceutical progesterone is made from wild yam using a chemical conversion process. This can lead to confusion—while wild yam can be a source of progesterone, it cannot be used without this pharmaceutical conversion, which cannot be duplicated by the body. Women who require progesterone should consult with their physician and not rely on wild yam supplements."
Wild Yam supposedly has other non-feminizing health benefits, so it might be good to take, but I'll drop it if I can confirm from some more sources that the body really can't use it to help with estrogen production.
Regarding Coenzyme Q10, I've never found anything that suggests it helps to feminize the body. However, I did find this from
http://www.health-n-energy.com:
"CoQ-10 is an enzyme found in all cells of the body. It occurs naturally, and is the co-factor in the electron transport chain between cells. If is lacking, the body's most important source of cellular energy is depleted, and many medical conditions are aggravated. It is most concentrated in the heart and liver, and is a vital component in the mitochondria, the body's metabolic factories. It is a powerful antioxidant, scavenging free radicals, sitting in the membranes with Vitamin E which it recycles to keep it most active. It has been shown that enhancing the body's CoQ-10 can:
Reduce many of the serious side effects of cholesterol and other prescription drugs such as adriamycin, beta blockers, and psychiatric drugs; Reduce the effects of aging; Aid in the recovery from a wide range of heart problems including angina pectoris, congestive heart failure and mitral valve prolapse; Reduce blood pressure and blood lipids at 60 mg day; Assist chronic fatigue sufferers when administered at 100 to 300 mg per day; Assist in weight loss by stimulating mitochrondria and thermogenic activity; Treat chronic gum disease; Building a strong immune system as a defense against all forms of disease; May normalize blood sugar levels; and<br>Help maintain a healthy brain."
