World No-Tobacco Day 2025 — Impact Of Tobacco On Reproductive Health
(By Dr. Bani Kumar Mitra)
Tobacco consumption continues to be a major global health challenge, responsible for millions of deaths annually and contributing to a wide range of chronic diseases. While its link to cardiovascular disease, respiratory illness, and cancer is well-known and documented, but its impact on reproductive health is often overlooked and awareness is less.
The chemicals present in tobacco products, whether smoked or chewed, adversely affect nearly every organ in the body—including the reproductive system. For individuals and couples trying to conceive, understanding how tobacco use affects fertility and pregnancy outcomes is essential. As fertility issues become increasingly prevalent in modern society in both men and women, recognizing and addressing the role of tobacco in reproductive health is more important than ever, making this an important public health concern.

Effects On Male Reproductive Health
Tobacco consumption has a profound and harmful impact on human health, and its effects on reproductive health are particularly alarming. In men, smoking significantly contributes to infertility by reducing sperm count, impairing motility, and altering morphology. These changes are primarily due to an increase in oxygen free radicals, which cause oxidative stress in the reproductive system. This oxidative damage compromises sperm quality, leading to lower fertilization and pregnancy rates. Moreover, tobacco toxins can lead to DNA fragmentation in sperm, which further reduces the chances of successful conception and may even impact the health of future offspring.
Effects On Female Reproductive Health
In women, the reproductive system is equally vulnerable to the effects of tobacco. Smoking leads to a decline in oocyte (egg) quality by increasing oxidative stress in the follicular environment, thereby affecting fertilization, embryo development, and implantation. The chances of miscarriage also rise significantly, and pregnancy complications such as intrauterine growth restriction (IUGR), placental problems, and preterm labor become more likely. These complications can result in low birth weight or small-for-gestational-age babies. In summary, tobacco use severely compromises both male and female reproductive potential, making it a critical factor to address in fertility care and pregnancy planning.
The harmful effects of tobacco on reproductive health are extensive, affecting both male and female fertility, pregnancy outcomes, and even the health of future children. In the context of fertility care and family planning, tobacco use should be considered a significant modifiable risk factor .As part of comprehensive fertility care, counseling and support for tobacco cessation should be prioritized.
Quitting tobacco is not only a step toward better overall health—it is a vital investment in future parenthood and the well-being of the next generation.
