Childlessness needs separate advice for female and male. What men and woman have in common, however, is that the reproductive functions are depending on hormones. While in men sperm quality can be limited by a nutrient deficiency in terms of mobility, speed and number of sperms, in women hormone imbalance can be the cause of unwanted childlessness.
A dominance of estrogen in relation to the partner hormone progesterone can be the possible cause, through too much soy in the diet or “xenoestrogens” (environmental hormones that can bind to estrogen receptors) or through medication such as the hormonal contraceptive pill.
An unfulfilled desire to have children can also be caused by disturbances in the zinc balance. As zinc is involved in the formation of sex hormones, the trace element also has a significant influence on the fertility of couples. In men, zinc is important for increasing the number of sperms, in women it regulates an irregular menstrual cycle.
