Males who smoke or vape may have: trouble getting and maintaining an erection. lower sperm count. damage to the DNA in sperm, causing health problems in your baby.
Both tobacco and vaping have direct effects on fertility, damaging egg and sperm quality and reducing the success of assisted reproduction treatments. Quitting these habits is one of the healthiest and bravest decisions you can make when trying to get pregnant.
We do know that many of the chemicals found in e-cigarettes have a negative impact on reproductive health for both women and men. Informative studies have raised concerns about reduction in fertility as a result of exposure to e-cigarette vapour and liquids. It is best to quit vaping if you're trying to fall pregnant.
Motility. Daily oral nicotine administration of 0.5 mg/kg and 1.0 mg/kg per body weight for a period of four weeks significantly decreased (P < 0.05) the progressive motility of the sperm when compared with the control group. Although, this observation was dose-dependent.
More than 90% of male infertility is caused by sperm abnormalities, including poor-quality sperm, low sperm count, abnormal morphology or a combination of all these. Other reasons that may affect a man's fertility are: anatomical problems, genetic defects and hormonal imbalances.
A complete lack of sperm occurs in about 10% to 15% of men who are infertile. A hormone imbalance or blockage of sperm movement can cause a lack of sperm. In some cases of infertility, a man produces less sperm than normal. The most common cause of this condition is varicocele, an enlarged vein in the testicle.
Signs and symptoms you may notice include:
Even with limited research on the long-term effects of vaping on fertility, what we do know suggests vaping could negatively impact sperm and egg quality, hormone levels and general reproductive health. Experts generally recommend waiting at least three months after quitting vaping before trying to conceive.
The longer you go without smoking, the better. It takes about three months to produce both sperm and eggs, so that's how long it will take after quitting smoking before fertility fully improves, for both you and your partner.
Transmission electron microscopy revealed no effect of smoking on sperm ultrastructure. Alcohol consumption resulted in significant increases in morphologically abnormal nuclei and plasma membranes.
Vape alternatives range from Nicotine Replacement Therapies (NRTs) like patches, gum, and lozenges, to nicotine-free flavored air inhalers (FÜM, Cigtrus) that satisfy oral fixation, to plant-based diffusers (ripple+), and prescription medications (Varenicline, Bupropion), offering ways to manage cravings and quit vaping with options focusing on flavor, habit replacement, or nicotine reduction. Other alternatives include heated tobacco products and nicotine pouches, or adopting lifestyle changes like exercise.
We look at research studies to try to understand if an exposure, like e-cigarettes, might increase the chance of birth defects in a pregnancy. It is not known if e-cigarettes can increase the chance of birth defects. Animal studies suggest that exposure to e-cigarettes during pregnancy can impact fetal development.
Five foods to avoid that may decrease sperm health and male fertility
Five negative effects of vaping include nicotine addiction, serious lung damage (like EVALI or "popcorn lung"), increased risk of heart problems, exposure to cancer-causing chemicals, and harm to adolescent brain development, leading to issues with learning, mood, and memory. Vaping also causes immediate issues like coughing, shortness of breath, nausea, and even explosions/burns from faulty devices.
Male smokers can suffer decreased sperm quality with lower counts (numbers of sperm) and motility (sperm's ability to move) and increased numbers of abnormally- shaped sperm. Smoking might also decrease the sperm's ability to fertilize eggs.
Some animal studies have found that e-cigarette chemicals damage sperm cells and reduce testosterone levels and this has now been confirmed in recent human studies. However, more long-term human studies are needed to better establish the link between vaping and male infertility in humans.
Signs of Unhealthy Sperm
Sperm Regeneration Simplified: The Bottom Line
Here are a few key takeaways: Sperm production is a continuous process, but it takes about 64 days for a single sperm cell to fully mature. Sperm reserves don't fully replenish in 12 hours, though your body keeps producing enough to meet the demand.
A significant increase in semen volume, sperm concentration and total sperm count was observed 3 months after smoking cessation (2.48 ± 0.79 ml vs. 2.90 ± 0.77 ml, p = 0.002; 18.45 × 106/ml ± 8.56 vs. 22.64 × 106/ml ± 11.69, p = 0.001; 45.04 ± 24.38 × 106 vs. 65.1 ± 34.9 × 106, p < 0.001, respectively).
Although numerous studies have linked maternal smoking during pregnancy with reduced sperm counts in resulting sons, a recently published investigation from Sweden has shown that men whose fathers smoked at the time of pregnancy had half as many sperm as those with non-smoking fathers.
What's off-limits?
Male infertility often is treatable with surgery, medication, hormone therapy, fertilization procedures, or lifestyle changes. Male infertility should not be confused with erectile dysfunction, which is the inability to get or keep an erection long enough for sex and usually is treatable.
Basic semen analysis will tell you: your sperm count (the higher this number, the better); how well your sperm move (motility); morphology (if your sperm are shaped normally); anti-sperm antibodies (which your immune system can produce after injury to the area or other inflammatory processes).
Shettles proposed that deep penetration during intercourse could be a factor in increasing the chances of conceiving a boy. Deep penetration allows the male partner to ejaculate closer to the cervix and uterus, helping the Y chromosome sperm reach the egg faster.
