Many people tend to believe occasional or social smoking is harmless because it does not happen daily. However, you will be shocked to know that even casual smoking can affect fertility, reproductive health, and future pregnancy outcomes in both men and women. It is time to quit smoking and keep the fertility health intact. According to doctors, even passive smoking can do a great deal of damage. But can it lead to infertility? Let's find out.What is passive smoking?In an interaction with Health and Me, Dr. Prajakata Choudhary, Fertility Specialist, Nova IVF Fertility, Andheri, Mumbai, spoke about the risks of passive smoking and how it may impact fertility.Passive smoking has become increasingly common among young adults, especially during parties, weekends, vacations, or stressful social situations. They tend to smoke only while socializing and think that it is not going to cause any harm. They don’t consider themselves smokers because they smoke only occasionally or “just for fun.” However, even occasional smoking can quietly affect fertility and reproductive health over time. Unlike regular smokers, social smokers often underestimate the impact cigarettes can have on the body. While the number of cigarettes may be lower, repeated exposure to nicotine and harmful chemicals can still affect hormone balance, egg quality, sperm health, and overall chances of conception.How bad is passive smoking for women?In women, smoking can take a toll on ovarian function and reduce egg quality. Moreover, harmful chemicals present in cigarettes may damage eggs and speed up the natural decline of ovarian reserve. Social smoking can also impact the hormone levels, making menstrual cycles irregular and reducing fertility over time. Can smoking prevent you from getting pregnant?Women who smoke, even occasionally, may also face a higher risk of miscarriage, ectopic pregnancy, and other complications like premature birth, low birth weight, miscarriage, placental problems, stillbirth, and breathing difficulties in the baby. In men, social smoking can impact sperm count, sperm movement, and sperm quality. It may also increase oxidative stress in the body, which can damage sperm DNA and affect reproductive health. Many men remain unaware of these effects because fertility problems often develop gradually and silently. ConclusionPassive smoking is also risky. Partners exposed to cigarette smoke regularly may experience reduced fertility even if they do not smoke themselves. This becomes especially important for couples planning pregnancy or undergoing fertility treatments like IVF, where lifestyle factors can influence treatment success. Another concern is that social smoking is often linked with alcohol use, late-night routines, stress, poor sleep, and unhealthy eating habits, which together may further affect fertility and hormonal balance.Quitting smoking completely can improve the chances of a healthy pregnancy and long-term well-being. So, even if you are at the party, don’t smoke.
