Hi Rosemary. I just now saw your question. Leaky gut causes an incredible amount of stress in the body. If you’re having digestive issues (such as diarrhea, constipation, etc.) this will affect your hormone levels as your body demands more cortisol to deal with the stressor. Your body’s defense mechanism will try to produce more cortisol by “stealing” hormones from other sources (mainly pregnenolone which is responsible for the production of all reproductive hormones). This causes hormonal imbalances and that in turn, may be a cause for infertility.
