Can women preserve their fertility longer through lifestyle choices?

Moderate evidence

Lifestyle can influence your fertility, but genetics largely determines when you go through menopause. Avoid frequent heavy drinking, limit exposure to air pollution and hormone-disrupting substances, and consider folic acid supplements up to 800 mcg per day if you want to protect your fertility.

Genetics is the single biggest factor determining when you go through menopause and how many eggs you have left. If your mother or sister went through menopause early, the chances are greater that you will too. Lifestyle can make some difference, but it always plays second fiddle.

The idea that smoking harms fertility is widespread, but a study of young African American women found no measurable reduction in ovarian reserve among smokers. This stands in contrast to what has been found in other population groups. So what applies to you personally is not clear-cut, and adjusting your smoking behaviour remains worthwhile for other reasons. Frequent heavy drinking is a different story when it comes to reserves: women who had binged on alcohol twice a week or more had 26% lower levels of the hormone that measures ovarian reserve, compared with women who did drink but had never binge-drunk. Moderate or occasional drinking was not associated with a lower figure.

You might expect the most from healthy eating, but the Mediterranean diet and similar pro-fertility diets were not associated with a higher antral follicle count (the maturing follicles that reflect reserve) in an observational study of women at a fertility centre. Overall dietary pattern therefore does not appear to measurably improve reserve. However, a different observational study did find that women who took folic acid supplements daily had a modestly higher reserve. The difference between 400 and 800 mcg of supplementary folic acid per day amounted to roughly one and a half extra follicles; above 800 mcg there was no additional benefit. Causality has not been established in observational studies of this kind.

Air pollution is a factor that few people have on their radar: higher exposure to particulate matter was associated with lower measured values of ovarian reserve, and the effect was stronger in women over 35. This is partly outside your control, but living and exercising in areas with high air pollution may have consequences. Exposure to hormone-disrupting substances in certain plastics (such as BPA) can negatively affect IVF outcomes, although the overall picture of lifestyle and IVF results is complex and variable.

In summary: there are modifiable factors, but the effects are modest and largely based on observational studies, not interventions. Avoiding frequent heavy drinking and limiting exposure to air pollution and hormone-disrupting substances are the most concrete steps you can take. Folic acid supplements up to 800 mcg per day are a modest additional option. If you think you may go through menopause early, discuss this with your gynaecologist so you can consider together whether additional monitoring makes sense.

The evidence
8 studies

All claims are based on reviews and observational studies. No randomised trials or meta-analyses are available demonstrating that lifestyle interventions causally improve ovarian reserve or the timing of menopause.

Can you delay menopause with lifestyle or diet?

Avoiding smoking, eating less red meat, and eating more citrus fruit and oily fish appear to have a favourable influence on the age of menopause. However, evidence from controlled experiments is still entirely lacking.

Preliminary evidence

Can hormones explain why women live longer on average than men?

Sex hormones likely contribute to women's longer lifespan, but they do not fully explain the difference. Social factors also play a role, and the hormonal protection has a clear downside after the menopause.

What does pregnancy do to your hormone balance in the long term?

Pregnancy brings about hormonal changes that are partly temporary, but in the case of gestational diabetes the risk of type 2 diabetes may remain permanently elevated. If you have had this, have your blood sugar checked afterwards.

Can stress make you infertile?

Prolonged, severe stress can genuinely disrupt fertility, but whether ordinary everyday stress alone is enough to cause infertility remains unclear. If you notice that your menstruation has stopped due to stress or overexertion, discuss this with your doctor.

Moderate evidence

What does chronic sleep deprivation do to your fertility when you are trying to conceive?

Chronic sleep deprivation and frequent insomnia have been linked in several large studies to a lower chance of conception and more reproductive problems. If you want to become pregnant, getting regular and sufficient sleep is a concrete starting point, even though causality has not yet been definitively proven.

What can help women increase their libido?

There are several well-supported options depending on your life stage: for women after menopause, transdermal testosterone has the strongest evidence base, and mindfulness therapy works for a broader group. Always discuss medication options with your doctor, as availability and long-term safety require a personal assessment.
