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 O.
