What to Expect During the Study

Gaining access to the ovaries is very similar to the egg retrieval procedure that is routinely performed for in-vitro fertilization (IVF).

Transvaginal (via the vagina) ultrasound guidance is used to visualize the ovary.

A thin needle is then inserted through the vaginal wall and into the ovary, similar to the technique routinely used for egg retrieval for IVF. Radio frequency energy is then delivered to gently heat the surrounding ovarian tissue.
After procedure

Weekly blood tests up to 3 months to check for ovulation


Follow up calls: 24 hours, 7 days and 30 days after the procedure

Follow up visits at the study center: 3, 6, 9, 12, 24, and 36 months after the procedure

Some participants will be part of a Control group who will receive no treatment. Participants who are randomly assigned to the Control group have the option to undergo the Ovarian Rebalancing procedure after their 3-month follow-up visit and will follow the same schedule for follow-up as described above.

The Ovarian Rebalancing procedure is currently investigational, and FDA has approved the clinical trial of the procedure.
