Vaping can risk a woman’s fertility because nicotine and flavorings in e-cigarettes reduce the quality of the egg a woman naturally produces each month. Poor quality eggs make it difficult to conceive or maintain a healthy pregnancy. What else? The nicotine and chemicals in e-cigarettes can inhibit a fertilized egg (embryo) from implanting in a woman’s uterus – Journal of the Endocrine Society, Study by the University of North Carolina at Chapel Hill, September 2019.
