WHO reports that smoking increases the risk of infertility in women by about 40%. The finding is based on a review of available evidence examining links between tobacco use and fertility outcomes.
The review also describes effects of smoking on male reproductive health. It associates smoking among men with reproductive dysfunction, including poorer sperm quality and problems such as erectile dysfunction and issues related to ejaculation. The outlets summarizing the WHO review present the findings as part of a broader assessment of tobacco’s health impacts on reproduction.
Both sources focus on the same central claims: a quantified increase in infertility risk for women and additional reproductive effects for men, without providing new study data beyond the WHO evidence review.
