A couple with secondary sterility is one in which, even if they have had a child previously, they do not get another pregnancy to extend the family. The main cause of this infertility is maternal age, since the woman's ovarian reserve decreases as she grows older.
There is a big difference between women who have previously had one child or more and now cannot achieve a new pregnancy, and those who are fighting infertility because they do not yet have children.
Still, couples experiencing secondary infertility have the same feelings of guilt, denial, anger, depression and frustration. They also have the added concern of how their actions and emotions may affect the child or children they already have.
