Could a common supplement boost antibiotic success for a hidden cause of infertility?

This study tests whether adding berberine (a natural compound) to the standard antibiotic doxycycline works better than doxycycline alone for chronic endometritis, an inflammation of the uterine lining that can cause infertility. About 206 women with the condition will take either the combination or the antibiotic alone for 14 days. The main goal is to see if the infection clears more often with the combination, and to track polyp recurrence.
