If you aren't comfortable with the idea of using animal embryos to diagnose embryo toxic factor, or you want a more natural approach to treatment than allopathic medicine has to offer, there are several natural remedies which may help to increase your production of the hormone progesterone and lower your immune response to help prevent miscarriage in any subsequent pregnancies.
Please note that none of these remedies are proven to cure embryo toxic factor and they should NOT to taken during pregnancy, but only as part of a pre-conceptual regime.
The allopathic (conventional) form of diagnosis and treatment of embryo toxic factor is also unproven as it is new and still in its experimental stages. As the diagnostic test uses mouse embryos, it may be inaccurate as human blood cells may reject mouse cells anyway and give a misleading result.
Wild Yam - this is a cream and can be put topically on the vulva to increase progesterone levels.
Vitamin Supplements - Supplement in vitamin Calcium, vitamin D, vitamin B5 and B6, zinc and magnesium which enable your adrenal glands to manufacturer your hormones more effectively. Check labels and make sure you take the right amounts, as it is possible to overdose on some vitamins.
Diet - limit your amount of soy intake. Foods containing soy beans increase the body's production of oestrogen which increase antibodies. This would heighten your (abnormal) immune response, instead of suppressing it.
Avoid processed and fatty foods, increase your intake of fruit and vegetables.
Take Omega 3 - this may regulate your body's hormones and your immune system. Sources are from oily fish. Vegetarian sources are linseed, flaxseed and it is contained in some yoghurt and yoghurt drinks. There is also a vegetarian and vegan omega 3 supplement in a tablet form.
