Repropedia is a reproductive dictionary created by an international team of scientists and clinicians led by investigators at Northwestern University. An editorial board reviews all entries to ensure that definitions are both accurate and accessible to scientists and non-scientists alike.

The Repropedia website exposes these term definitions via a free-to-use API, and provides a tooltip that can be used to highlight Repropedia terms, and provide embedded tooltip definitions for instances of the terms on other websites.
