In fertility, as in other fields of medicine, we often find scientific terms that can be confusing or difficult to understand, for this reason we decided to publish this series “Fertility from A to Z” as a glossary of terms that you will find on the way to fulfill your dream to have a baby.
Next we have for our patients the definitions of terms and keywords of health, reproduction and fertility treatments with the letter I.

Implantation

Adhesion of the fertilized egg in the inner lining of the uterus (endometrio).

Unexplained infertility

Term used when not in the initial basic study, the reason to explain the cause of subfertility in a couple.

Primary infertility

It is that couple that has never achieved a pregnancy.

Secondary infertility

Inability to conceive or achieve a pregnancy after having conceived and achieved one or more pregnancies.
