Secondary infertility is when a couple who has already naturally conceived a child experiences difficulties in becoming pregnant again. When a childless couple is unable to conceive, they tend to seek advice or treatment.

Several lifestyle tendencies, injuries or diseases, which may have occurred since the past pregnancy, could impact fertility the second or third time around. All of the same fertility factors listed in this section should be taken into consideration when assessing secondary infertility.
