Why might my treatment have not worked?
You should talk to your doctor about why your treatment has been unsuccessful. Broadly speaking, there are two main reasons why treatment doesn't work.
The embryos fail to develop in the womb
This is the most common reason for treatment being unsuccessful. Often there’s no obvious explanation although reasons could include:
- The egg may not have matured properly, or may not have divided as it should after fertilisation, leading to the embryo failing to implant in the womb.
- Many embryos that look healthy have faulty chromosomes (the structures inside cells that contain genes and control how the cells work).
- Poor blood flow to the womb could mean you have less chance of getting pregnant and a greater chance of miscarriage if you do conceive.
