Who They Are:
The authors of The Feronia Project vary in our upbringing, education, and experience, but the common thread between us is our unwavering belief that reproductive rights are human rights.
What They Do:
This site provides a safe place to learn about sexual health, engage in discussion about social and reproductive justice, and find trusted resources for comprehensive, medically-accurate sex education.
