Deep posterior endometriosis surgery and ovarian reserve
Official title: Impact of Surgery for Deep Posterior Endometriosis on Ovarian Reserve
Run by GCS Ramsay Santé pour l'Enseignement et la Recherche · NCT07469007 · Data updated 2026-11-12
This trial will test whether surgery for severe deep posterior endometriosis changes ovarian reserve in women aged 18 to 39 who do not have ovarian endometriomas.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are women 18–39 with imaging or laparoscopic confirmation of severe deep posterior endometriosis, no endometrioma >5 mm, eligible for surgery, and covered by social security.
✕Probably not a fit
Patients with ovarian endometriomas, prior surgery for severe deep endometriosis, severe low ovarian reserve (AMH <1 ng/mL and AFC <8), menopausal women, or those with BMI >35 are unlikely to benefit from this protocol.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Women aged 18–39 with suspected or confirmed severe deep posterior pelvic endometriosis and no ovarian endometriomas will undergo planned surgical resection. Ovarian reserve will be measured before and after surgery using anti‑Müllerian hormone (AMH) assays and pelvic ultrasound including antral follicle count, and participants will complete symptom and reproductive history questionnaires. The study excludes patients with prior surgery for severe deep endometriosis, significant preoperative ovarian insufficiency, recent GnRH agonist use, BMI >35, or menopause. The trial is conducted at Clinique la croix du sud in Quint‑Fonsegrives and is sponsored by Ramsay Générale de Santé.
Why it matters
Potential benefit: If successful, results could help doctors and patients understand fertility risks of surgery and improve counseling and surgical planning.
How similar studies have gone: While ovarian reserve loss after cystectomy is well documented, the specific impact of surgery for severe deep posterior endometriosis without ovarian involvement has not been previously studied.
