A healthy couple can have fertility problems due to environmental factors that affect the production and quality of sperm in men, and causes alterations of the menstrual cycle and ovulation in women. Therefore, a truly healthy life is essential to increase the chances of pregnancy: to reduce caffeine intake, to avoid tobacco and alcohol, to exercise, to sleep well, to have a balanced diet with the presence of vegetables and cereals and to try to reduce stress as far as possible.
It is also important to have a deep knowledge of monthly fertile windows (ovulation periods).Methods such as basal temperature control, the Billings method through vaginal secretions or using an ovulation test can be useful for such a purpose.
