Day-specific cervical-vaginal fluid die swell ratio (CVF B) for two PCOS cycles, in which ovulation was induced with metformin treatment, compared with the mean day-specific CVF B for four ovulatory normal cycles: metformin-induced ovulation did not restore a normal CVF B signature. Results for PCOS patients, PT3 and PT6, and normal patient, PT4 (cycles PT4-1,2,3,4), are shown. Metformin treatment in patients PT3 and PT6 was for 12 months and 4.5 months, respectively. Even with metformin treatment, cycle PT6(PCOS+M) generated scant daily CVF volume (<0.2ml) and consequently die swell ratio measurements were limited (Day +4).
