Results
The numbers of mature follicles and retrieved oocytes, and fertilization rates did not differ between the two groups. Implantation rates and pregnancy rates tended to be higher in the UL group compared with the C group. TNFa and 8OHdG concentrations in the follicular fluid were significantly lower in the UL group than those in the C group, while melatonin concentrations were significantly higher in the UL group compared with the C group.

Baseline Characteristics
Twenty-three infertile female patients with endometriosis were recruited for this study. Severity of endometriosis was scored according to the four-stage classification of the revised American Society for Reproductive Medicine (rASRM) score, and all patients had stage III or IV endometriosis. 
Participant flow
Eleven patients received three courses of GnRHa (1.8 mg s.c. every 28 days), followed by a standard controlled ovarian hyperstimulation (COH) for IVF-ET (ultralong group). The other 12 patients received a standard COH with mid-luteal phase GnRHa down-regulation (control group). 
Adverse events
none
Outcome measures
The numbers of matured follicles and retrieved oocytes, fertilization rates, implantation rates, clinical pregnancy rate, and intrafollicular concentrations of TNFa, 8-OHdG and hexanoyl-lysine adduct (HEL) as oxidative stress markers, and melatonin and Cu,Zu-superoxide dismutase (Cu,Zn-SOD) as antioxidants
