What happens to infertile couples?

I saw a patient today whose husband left her because their infertility is due to a problem with her. How often does a person leave their spouse because of infertility?

There have been a few large European studies that attempt to answer that question. You can read a recent article that includes a summary of past studies here.

The summary is that when couples are followed for up to 20 years after IVF treatment (successful or not) about 70% of them are still together. The chance they are still together is the same whether or not they have children.
