Women&More study in the Netherlands has started!

On April 14, 2025 Leiden University Medical Center started the Women&More study. 

In this study, researchers aim to demonstrate that mifepristone 50 mg is an effective and safe contraceptive option.

Unlike traditional contraceptive methods—such as the pill, patch, vaginal ring, injection, hormonal IUD, or implant—this medication does not contain estrogen or progestogen. As a result, it is expected to cause fewer side effects compared to hormone-based contraceptives.

Participants in the study will take one 50 mg tablet of mifepristone per week for a year, using it as their sole method of contraception.

The researchers aim to:

  • Show that the risk of pregnancy is very low
  • Confirm the safety of the drug and monitor for any serious health effects
  • Evaluate whether it causes fewer side effects than hormonal contraceptives
  • Understand how participants experience taking one tablet per week

If the results are positive, the ultimate goal is to register mifepristone 50 mg as a contraceptive with regulatory authorities—offering a hormone-free option and expanding the range of choices available for birth control in the future.
