Summary
This early-stage study tests a new vaginal ring that releases the hormone progesterone. Researchers want to see how much progesterone gets into the blood over 14 days. The study involves 60 healthy postmenopausal women and compares two ring doses to a standard insert. This is not a treatment study; it gathers information for future preterm birth prevention.
