The womens Wellness Intrauterine Neuroimmune modulation Study Expansion Group: The effect of a new intrauterine device on pelvic pain in women.

Alyra Biotech Pty Ltd is an Australian-owned biopharma company that wishes to develop an optimal intrauterine contraceptive device (IUD) for people with period or pelvic pain. The use of IUDs globally is increasing, however some people experience increased pelvic pain in the 3-6 months following insertion, causing them to have the device removed. They then miss out on the benefits that IUDs can provide, such as; reducing your lifetime exposure to synthetic hormones; decreasing the amount of blood loss at each period; as well as decreasing intense period pain, over time with continual use. Alyra Biotech Pty Ltd has developed and patented a novel IUD designed to reduce the severity of post-insertion pain in those that experience it, giving them access to the benefits of IUD use. The objectives of this study are: 1. To determine how the device performs at releasing the appropriate medicinal drugs (pharmacokinetics). 2. To compare the tolerability of the new Alyra device with the currently approved for use in Australia, the Mirena 'Trademark" device. 3. To establish the expected number of days of bleeding following insertion 4. To determine the number of days and intensity of pain experienced following insertion
