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.
