Safety and Acceptability Study of a Non-Hormonal Ring
a study on Contraception
This is a feasibility, multi-center, open-label, non-significant risk device study for a non-hormonal contraceptive ring.
The purpose of this clinical trial is to assess the ability of Ovaprene™ to prevent sperm from penetrating midcycle cervical mucus. In addition, safety, release of ingredients, acceptability and fit will be assessed.
