Fast food and pregnancy

Fast food and pregnancy

As society searches for convenience through dining out more – you may be wondering – can fast food cause infertility?

Studies have previously shown a strong link between smoking, obesity and longer time to pregnancy (TTP) or infertility. Recently, researchers have investigated the role diet may play on fecundity or the amount of time taken to fall pregnant.

A study at the University of Adelaide’s Robinson Research Institute has revealed a link between pre-pregnancy fast food and fruit intake and the amount of time to fall pregnant.

The research institute found that higher intakes of fast food and lower intakes of fresh fruit and vegetables were both directly associated with lowered fecundity rates and infertility. Although research into pre-pregnancy diets and TTP in humans has not been a topic largely investigated, there have been factors that have been identified as having a negative effect on couples trying to conceive such as fast food intake and the increased consumption of foods high in saturated fat, sodium and sugar.

The cohort study did show that small modifications in dietary intake may have benefits for increasing fertility in couples trying to conceive.

FAQs about improving natural fertility

Will stress affect my ability to get pregnant?

Yes, chronic stress can impact fertility by disrupting hormonal balance and ovulation patterns. Managing stress through relaxation techniques, regular exercise, adequate sleep, and mindfulness practices may help optimise your chances of conception. Consider speaking with a counsellor if stress feels overwhelming.

How does my partner's health affect our fertility?

Sperm health accounts for about 40% of conception challenges. Your partner can improve sperm health by maintaining a healthy weight, avoiding excessive heat exposure (hot tubs, saunas, tight clothing), limiting alcohol, quitting smoking, managing stress, and taking a multivitamin with antioxidants. Sperm takes about 3 months to develop, so lifestyle changes need time to show results.

When during my cycle am I most fertile?

Your fertile window typically spans 5-6 days, ending on ovulation day. For a regular 28-day cycle, this usually falls between days 10-15, with peak fertility 1-2 days before ovulation. Track your cycle using ovulation predictor kits, basal body temperature, or cervical mucus changes to identify your unique pattern. Having intercourse every 1-2 days during this window optimises your chances.
