Hydrosalpinx halves IVF success rates
A damaged, fluid-filled fallopian tube (hydrosalpinx) reduces IVF success rates by approximately half due to embryotoxic fluid washing back into the uterus.

Clinical case example #4: Surgical decision-making in endometriosis — balancing pain relief, fertility preservation, and common treatment pitfalls
At 1:21:20 · chapter starts 1:21:03
This case focuses on surgical pitfalls and reveals how even well-intentioned interventions can cause lasting harm. The first mistake is performing surgery on a patient whose primary pain is nociplastic: central sensitization is not responsive to lesion removal, and operating without pelvic floor physiotherapy preparation sets the patient up for disappointment. [1] — Renato Tomioka "Hydrosalpinx halves IVF success rates: A damaged, fluid-filled fallopian tube (hydrosalpinx) reduces IVF success rates by approximately hal…" 1:21:20 The second pitfall is removing endometrioma cysts before egg retrieval. Endometriomas are pseudo-cysts without clean walls — stripping them invariably takes adjacent ovarian cortex where primordial follicles live, reducing AMH by 40 to 50% in published data. [2] — Renato Tomioka "Cystectomy can reduce AMH by 40–50%: Removing endometrioma cysts surgically can reduce ovarian reserve (measured by AMH) by 40 to 50% becau…" 1:19:15 The Fenton reaction (iron-catalyzed hydroxyl radical production inside the cyst) simultaneously destroys follicles from within, making it a double-edged sword. The correct sequence: retrieve eggs first, then decide on surgery. The third mistake is leaving a dilated, damaged fallopian tube (hydrosalpinx) in place. The embryotoxic fluid it drains back into the uterus cuts IVF success rates by approximately half — a finding supported by Cochrane review. Salpingectomy is the standard of care.
