If you had issues with IVF treatments in the past, or the female partner has problems with her ovaries due to her age or unknown reasons, or the male partner has azoospermia or other sperm abnormality, you will be guided to consider donor eggs and sperms.

In short, artificial insemination or IVF using sperm or egg from a donor is most appropriate when fertilisation is impossible using sperm or egg from your spouse.
