Lower live birth rates in IVF likely when mother consumes high quantities of dietary fat

Lower live birth rates in IVF likely when mother consumes high quantities of dietary fat
Women with a higher intake of dietary saturated fats have fewer mature oocytes available for collection in IVF, according to results of a study from the Harvard School of Public Health funded by the US National Institutes of Health. The study investigated the effect of dietary fat (classified as total, saturated, monounsaturated, polyunsaturated, omega 6, omega 3 and trans) on a range of preclinical and clinical outcomes in women having IVF.

Women with a higher intake of dietary saturated fats have fewer mature oocytes available for collection in IVF, according to results of a study from the Harvard School of Public Health funded by the US National Institutes of Health. The study investigated the effect of dietary fat (classified as total, saturated, monounsaturated, polyunsaturated, omega 6, omega 3 and trans) on a range of preclinical and clinical outcomes in women having IVF. Results showed that the intake of saturated fat was inversely related to the number of mature oocytes retrieved, while polyunsaturated fat consumption was inversely associated with early embryo quality.(1)

On the question of recommendations to IVF patients, Professor Chavarro said: "While these results are interesting, this is the first time to our knowledge that dietary fats have been linked to treatment outcome in IVF. So it is important that our results are replicated in other studies before making strong recommendations about fat intake to women having infertility treatment."
