Success in Achieving Pregnancy

A 5-year study of the Billings Ovulation Method® with couples wishing to achieve pregnancy showed a known pregnancy rate of 78%.   This study was conducted by Research Team of Ovulation Method Research and Reference Centre of Australia from 1999-2003.   The pregnancy rate was 65% in sub-fertile couples and 66% in women aged over 38.  Of the couples in the study who had previously attempted IVF or AI (artificial insemination) without success, 35% conceived naturally with the Billings Ovulation Method®.
