Birth Control

  • Contraceptive Clinical Trial for Healthy Women 16-40

    UC Davis Obstetrics and Gynecology Research is conducting a contraceptive clinical trial looking at two intrauterine devices, one of which is investigational.

    Pre-menopausal women ages 16-40 who are generally healthy, sexually active, at risk for pregnancy, and are not at risk for sexually transmitted infections may qualify.

    Call the UC Davis Obstetrics and Gynecology Research number at 916-734-6846 or email us at hs-obgynresearch@ucdavis.edu.

  • Hormonal Vaginal Ring Study
    This clinical trial will study the efficacy, bleeding patterns, and safety of a new contraceptive vaginal ring over 12 months. The ring in this study is used for three months before it is changed.

Studies Needing Women Not at Risk for Pregnancy

  • Estrogen-Free Pill Study
    We know that birth control pills are most effective when taken at the same time every day. We are conducting a study of an estrogen-free (progestin-only) birth control pill to learn more about the effect on cervical mucus and ovulation if you skip a pill or take a pill late.

  • New Non-Hormonal Contraceptive in Development
    This study will help us understand more about how well an experimental non-hormonal vaginal meshed ring works in preventing sperm from getting into a woman’s cervical mucus (the fluid at the opening to the uterus, or womb), to understand how easy it is to put in and take out the study ring, and how well the study ring fits.


  • COMPARE Research Study
    A nationwide study to help women and doctors better understand the effects of different treatments options for fibroids.
