Is this trial a fit for you?
✓Likely a good fit
Women with PCOS (Rotterdam criteria) who have infertility and have not responded to first-line medical treatment and are candidates for ovarian drilling.
✕Probably not a fit
Patients without PCOS-related infertility symptoms or those unlikely to benefit from surgical ovarian drilling may not experience improvement and could face surgical risks.

What this trial studies
This interventional study investigates ovarian drilling performed with vNOTES laparoscopy as a second-line option for women with PCOS and infertility after failure of initial medical therapy. Participants have PCOS diagnosed by Rotterdam criteria and are seeking fertility treatment, including those with primary or secondary infertility. The procedure compares a vaginally guided, scar-minimizing approach to traditional abdominal laparoscopy, focusing on feasibility and safety. Eligible patients must meet criteria, consent, and not have prior ovarian drilling or other exclusionary conditions. The trial is conducted at CHU Clermont-Ferrand under the lead sponsor University Hospital, Clermont-Ferrand.
Why it matters
Potential benefit: If successful, participants may experience improved ovulation and fertility outcomes with a less invasive surgical option.
How similar studies have gone: Prior ovarian drilling approaches have shown benefit in select PCOS patients, but the efficacy of vNOTES-guided drilling remains to be established.
