WHO Sounds Alarm: Smoking Wrecks Fertility, Quitting Offers Hope for Parenthood

The World Health Organization (WHO) has dropped a critical new 'knowledge summary' on September 8, 2026, delivering a stark warning that smoking significantly harms fertility in both men and women, with women who currently smoke facing a 40 percent higher risk of infertility. This comprehensive publication consolidates decades of evidence, making it clear that kicking the habit isn't just good for overall health, it could be the key to starting a family. The report emphasizes that even past smokers can see a significant improvement, with their infertility risk dropping by 25 percent compared to those who continue smoking. The global health agency highlighted that infertility, defined as the inability to achieve pregnancy after 12 months of regular unprotected sex, now affects a staggering one in six people worldwide, underscoring the immense societal impact of this issue. For men, tobacco use is linked to a range of reproductive problems, including poor sperm quality, abnormal sperm shape, and issues like erectile dysfunction and ejaculation problems. Beyond direct smoking, the WHO also stressed that exposure to second-hand smoke can reduce fertility chances for both men and women. For couples pursuing Assisted Reproductive Technologies (ART) like In Vitro Fertilization (IVF), smoking can severely diminish success rates, potentially cutting the chances of a successful pregnancy by half. With these updated warnings, the WHO is urging healthcare providers globally to proactively inform individuals and couples about the profound reproductive risks of tobacco use and to offer evidence-based support for quitting. This push is part of broader public health initiatives aimed at curbing tobacco use, including newer products like e-cigarettes and waterpipes, whose long-term effects on fertility are still being researched. As the world grapples with rising infertility rates, the message is clear: quitting tobacco isn't just a personal health choice, it's a vital step towards safeguarding future generations.
