It is often beyond the logic of some patients with previous children that they are now facing infertility problems. However, it is possible to have achieved a pregnancy and subsequently have difficulties in achieving a new pregnancy.
This situation is called secondary infertility and, although it may have other causes, it is often related to the woman's age. This is because age has a negative effect on female fertility, due to the decrease in the quality and quantity of eggs over time. Thus, a woman with previous children may find it difficult to become pregnant if she has reached an advanced maternal age.
