Secondary infertility defined

Secondary infertility can be defined simply as the inability to conceive a child after conceiving and giving birth. This happens when a couple may have one or two children already but are un able to continue to conceive.

Here is a more scientific definition of it:

“There are two basic categories of infertility – primary and secondary infertility. Primary infertility is defined as the inability to achieve a pregnancy or carry it to term successfully. This infertility definition refers to women who have never conceived or carried a child to term. Secondary infertility is diagnosed when a woman has previously carried at least one child to term. It is defined by a current loss of the ability to do so again, or a decrease in the body’s ability to manage difficulties previously overcome.”
