Infertility is the inability to conceive or carry a fetus to birth and can be caused by various factors such as diseases, developmental problems, inadequate nutrition, stress, toxins, and aging.
Infertility is the inability to conceive or carry a fetus to birth. About 75% of causes of infertility can be identified. These include diseases (such as sexually-transmitted diseases that can cause scarring of the reproductive tubes in either men or women) or developmental problems frequently related to abnormal hormone levels in one of the individuals. Inadequate nutrition, especially starvation, can delay menstruation. Stress can also lead to infertility. Short-term stress can affect hormone levels, while long-term stress can delay puberty, causing less-frequent menstrual cycles. Other factors that affect fertility include toxins (such as cadmium), tobacco smoking, marijuana use, gonadal injuries, and aging.
