Smoking is a widespread habit with profound implications not just on overall health but specifically on fertility for both men and women. Despite public health campaigns and increasing awareness, many people remain unaware of just how significantly smoking can impact reproductive health. Here, we explore the ways smoking affects fertility, the potential consequences for both genders and how quitting can improve the chances of conception.
Smoking has long been recognized as a detrimental habit that poses risks to nearly every organ in the body. According to the Centers for Disease Control and Prevention (CDC), smoking is linked to multiple diseases and conditions, including heart disease, lung cancer, and chronic respiratory illnesses. However, its impact on fertility is often overlooked. Research indicates that smoking can delay the time it takes to conceive, increase the risk of infertility, and negatively impact assisted reproductive technologies like In Vitro Fertilization (IVF).

How Smoking Affects Female Fertility
Reduced Ovarian Function
One of the most significant ways that smoking impacts female fertility is by reducing ovarian function. Studies show that chemicals in cigarettes, such as nicotine and carbon monoxide, disrupt the body’s ability to produce and release eggs. This disruption can lead to a reduction in ovarian reserve, which is the number and quality of eggs a woman has. Women who smoke are more likely to experience:
- Decreased Egg Quality: The quality of eggs is essential for conception and the healthy development of a pregnancy. Toxins from cigarette smoke accelerate the loss of eggs and can lead to chromosomal abnormalities in the eggs that remain.
- Premature Ovarian Aging: Women who smoke tend to experience ovarian aging at a faster rate than non-smokers. This can lead to early menopause, which directly impacts fertility.
Hormonal Imbalances
Smoking also interferes with the body’s hormonal balance, which is critical for reproductive health. Hormones such as estrogen and progesterone regulate the menstrual cycle and prepare the body for pregnancy. Nicotine and other chemicals in cigarettes can alter the production and functioning of these hormones, leading to irregular menstrual cycles and reduced fertility.
Increased Risk of Ectopic Pregnancy
Smoking is a known risk factor for ectopic pregnancy, a condition where a fertilized egg implants outside the uterus, typically in a fallopian tube. This occurs because smoking damages the fallopian tubes, impairing their ability to transport the egg to the uterus. Ectopic pregnancies are not viable and can pose severe health risks to the mother.
“The chemicals in cigarette smoke may put you at risk for an ectopic pregnancy. Ectopic pregnancy occurs when a fertilized egg fails to reach the womb, but instead begins to grow outside of the womb. This serious condition almost always results in death of the unborn child, and in some cases, death of the mother as well.” –FDA
Impact on Assisted Reproductive Technologies (ART)
Women who smoke are less likely to succeed with ART procedures such as IVF. Research has found that smoking significantly lowers the chances of successful implantation and pregnancy. One study published in Human Reproduction revealed that women who smoked required nearly twice as many IVF cycles as non-smokers to achieve pregnancy. The reduced success rate is likely due to the negative impact smoking has on egg quality and uterine receptivity.

Reduced Sperm Quality and Quantity
Men’s reproductive health is also heavily influenced by smoking. Sperm health is a crucial factor in achieving a successful pregnancy, and smoking has been shown to affect multiple aspects of sperm quality, including:
- Sperm Count: Smoking has been linked to lower sperm counts, which reduces the likelihood of fertilizing an egg.
- Sperm Motility: The ability of sperm to swim efficiently is known as motility. Reduced motility makes it harder for sperm to reach and fertilize an egg.
- Sperm Morphology: The shape and structure of sperm, or morphology, are essential for successful fertilization. Smoking can cause sperm to develop abnormally, affecting their ability to penetrate an egg.
DNA Damage in Sperm
Beyond affecting the physical characteristics of sperm, smoking can also result in DNA fragmentation. The chemicals found in cigarette smoke, such as cadmium and lead, can damage sperm DNA, which in turn increases the risk of miscarriage and congenital disabilities in offspring. Damaged DNA may not be immediately apparent, but it can significantly reduce the chances of successful conception and increase the risk of genetic abnormalities in the baby.
Secondhand Smoke and Fertility
Secondhand smoke is not just harmful to general health; it also poses risks to fertility. Women who are exposed to secondhand smoke may experience reduced ovarian reserve and irregular menstrual cycles, similar to active smokers. Men exposed to secondhand smoke may also see a decrease in sperm quality. The toxic chemicals inhaled indirectly can have nearly the same negative impacts as firsthand smoking, emphasizing the importance of a smoke-free environment for those trying to conceive.

Quitting Smoking: The Path to Improved Fertility
Benefits for Women
Quitting smoking has a profound positive effect on a woman’s fertility. Within a few months of quitting, the body begins to repair itself, leading to improved ovarian function and increased chances of conception. Although egg quality cannot be fully restored, stopping smoking can slow down the rate of ovarian aging, improve hormonal balance, and make ART procedures more effective.
Benefits for Men
For men, quitting smoking can lead to significant improvements in sperm quality. Studies have shown that sperm count, motility, and morphology can improve within three months of quitting due to the sperm production cycle. Additionally, stopping smoking reduces oxidative stress and decreases DNA damage, enhancing the overall genetic quality of sperm.
General Health Improvements
Both men and women who quit smoking also benefit from better general health, indirectly supporting reproductive health. Improved cardiovascular function, better lung capacity, and a stronger immune system all contribute to creating an optimal environment for conception and a healthy pregnancy.
Support Systems for Quitting
Quitting smoking is challenging, but there are multiple resources available to assist those looking to stop. These include:
- Counseling and Support Groups: Both online and in-person support groups provide emotional and psychological support.
- Nicotine Replacement Therapy (NRT): Products such as nicotine patches, gum, and lozenges help manage withdrawal symptoms.
- Prescription Medications: Drugs like varenicline (Chantix) and bupropion (Zyban) can help reduce cravings and withdrawal symptoms.
- Lifestyle Changes: Engaging in regular physical activity, maintaining a healthy diet, and practicing stress-relief techniques such as mindfulness can enhance the likelihood of successfully quitting smoking.
The Role of Healthcare Providers and Fertility Specialists
For couples planning to conceive, it is crucial to consult with healthcare providers who can offer tailored advice and treatment options. Fertility specialists often emphasize the importance of smoking cessation as a critical step in preconception health. They can provide personalized plans and connect patients with smoking cessation resources. Clinics specializing in reproductive health, such as MOM Fertility Center in Tehran, offer comprehensive support to ensure patients are informed and prepared for their fertility journey.
