How does nicotine affect the developing embryo?

It’s no surprise that studies have shown repeatedly that nicotine has detrimental effects on your health.

Cigarette smoking has also been linked to impaired fertility in both men and women too and it’s common knowledge that smoking while pregnant can increase your chances of having a miscarriage, reduces birth weight and increases the likelihood of having a premature birth, but what about your developing embryo?

Research published in Stem Cell has reported that exposure to nicotine interferes with the ability of cells in the embryo to communicate with each other, elevated the level of DNA damage, interfered negatively with other cellular processes and increased cell death.

They found that smoking and nicotine consumption increases the pathological risk to endocrine, reproductive, respiratory, cardiovascular and neurological systems that all rely heavily on cell-to-cell communication. Again, this is another study that has shown a significant link between embryo health and development and the negative impact prenatal nicotine toxicity has.

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.
