Smoking during pregnancy harms your baby and may lead to a greater chance of:
Miscarriage & Infertility
Birth complications
Having an underweight baby, makes them more vulnerable to infection and health problems in adulthood
premature birth (earlier than 37 weeks)
Baby being born with weaker lungs
Infant mortality - babies of mothers who smoke before and after birth are three times more likely to die from Sudden Infant Death Syndrome (SIDS)
Both women and men who smoke are more likely than non-smokers to struggle with infertility
Smokers suffer from higher rates of miscarriage and stillbirth than non-smokers
Smoking can damage eggs and ovaries, leading to lower egg quality and even earlier menopause
Cigarette smoking reduces sperm quality, giving you a lower sperm count, less semen, and poorer sperm movement
In 2019, a Danish study was published in the journal Human Reproduction, which examined the association between smoking and infertility in men and women. The study involved over 6,000 women and 4,000 men who were seeking fertility treatment between 1996 and 2018.
The results of the study showed that smoking was associated with a significantly higher risk of infertility in both men and women. Among women, the risk of infertility increased with the number of cigarettes smoked per day, with heavy smokers (more than 20 cigarettes per day) having the highest risk of infertility. The study also found that smoking during pregnancy increased the risk of miscarriage.
In men, the study found that smoking was associated with lower sperm counts and motility, as well as a higher percentage of abnormal sperm. The study also found that quitting smoking improved sperm quality, with men who quit smoking having higher sperm counts and motility compared to men who continued to smoke.
