The results of a study in Scotland have indicated that obese and overweight women have the same chance of successful IVF treatment as normal weight women. The research was undertaken in Aberdeen between 1997 and 2006, on 1,700 women undergoing their first cycle of IVF, and included overweight women, and women who were clinically and heavily obese. No marked difference was noted in the proportion of positive pregnancy tests, ongoing pregnancies and live births between any particular weight group. In addition, no further cost was incurred by women with a body mass index (BMI) of up to 35 (individuals with a BMI of over 25 are classed as overweight, while those over 30 are classed as obese).
However, the study showed that a higher proportion of women in the overweight and obese groups had a miscarriage and needed higher doses of drugs to stimulate their ovaries during their treatment. The higher rate of miscarriage echoes the findings of a study conducted last November by scientists at the Stanford University School of Medicine in California, US, which suggested that a mother's weight can affect the outcome of an otherwise normal pregnancy.
