WHO Warns Tobacco Smoking Reduces Fertility Risks

The World Health Organization (WHO) issued a warning regarding the impact of tobacco smoking on fertility, stating that it may reduce the chances of conceiving for many people worldwide. In a knowledge summary published on Tuesday, WHO noted that tobacco use is associated with infertility in women and harmful effects on sperm and sexual function in men.

A systematic review of studies from 2000 to 2026 indicated that women who smoke have a 40% higher risk of infertility compared to non-smokers. Furthermore, quitting smoking can significantly lower this risk.

The review also highlighted that smoking in men is linked to reproductive dysfunction, including erectile dysfunction and abnormal sperm characteristics. WHO emphasized that second-hand smoke exposure could also negatively affect fertility, increasing infertility risks for women.

The agency called for further research on newer tobacco products, as evidence remains limited. WHO recommended that healthcare providers inform individuals and couples planning pregnancy about these reproductive risks.
