Secondary infertility is the inability to become pregnant despite already having one or more children and conceiving them without any difficulty whatsoever. In many cases, no reason can be found for this secondary infertility, putting it under the ‘unexplained’ umbrella.

Where a cause can be found for this inability to conceive another child, the reasons include:

  • A woman’s age and therefore her egg quality or ovarian reserve
  • Pelvic adhesions or scar tissue from a previous surgery (including a Caesarean birth)
  • A build-up of endometriosis
  • PCOS
  • A decline in the quality of the man’s sperm

Secondary infertility is often very upsetting and hard to understand, particularly if you became pregnancy fairly easily previously.
