Can e-cigarettes damage your sperm?

A new study released from the University of Copenhagen has identified a troubling link between the use of e-cigarettes and reduced semen quality.

We have posted previously about the harmful effect cigarettes can have on the quality of your sperm and why it is so important to quit smoking if you are wanting to start a family, however the use of e-cigarettes hasn’t been fully investigated, until recently. Smoking can cause a dysfunction in the Sertoli and Leydig cells, specialised cells located in the tests that are responsible for the production of healthy sperm. Impairment to these testicular cells result in damage to the testes, alterations of male reproductive hormones and often result in reduced semen quality.

Researchers from the Department of Growth and Reproduction at the University of Copenhagen analysed the reproductive hormone levels of men and their semen parameters, and looked at their lifestyles, which included smoking behaviours. Approximately half the population of the study group were cigarette smokers and 13% used e-cigarettes. Compared to non-smokers, the study found that daily e-cigarette smokers had a significantly lower sperm concentration as did normal cigarette smokers.

Although e-cigarettes contain fewer components than actual cigarettes, the composition of the e-liquid created for e-cigarettes appears to cause histopathological changes in the testes, revealing adverse effects. Furthermore, additional studies that have come out of The University of North Carolina have supported these findings. The research shows a strong correlation between the use of e-cigarettes and significant delays in embryo implantation, as well as long term health implications and abnormal metabolism of female offspring when e-cigarettes are used during pregnancy.

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.
