Innovative Intrauterine Devices (IUDs)


The IUD, developed by Dr. Gradil, self-assembles and stays in place. The small size facilitates quick insertion and once set, is self-retaining and easy to remove. Unlike previously developed IUDs, both detection and removal are simplified. Once the IUD is in the uterus, the ovaries will produce progesterone for long periods of time without the need to give mares any drugs. The device can stay in place for five to seven months during the performance season.
