Does Tobacco Cause Infertility?


Yes, tobacco use, both in the form of smoking and smokeless tobacco, has been linked to infertility in both men and women.

In Women:

  1. Menstrual Irregularities: Smoking has been associated with menstrual irregularities and disruptions in the normal hormonal balance in women. These changes can affect the regularity of menstrual cycles and ovulation.
  2. Reduced Ovarian Reserve: Smoking may lead to a reduction in ovarian reserve, meaning that women may have fewer viable eggs available for fertilization.
  3. Increased Risk of Miscarriage: Smoking during pregnancy increases the risk of miscarriage and complications, which can impact fertility.

In Men:

  1. Sperm Quality: Smoking has been shown to have detrimental effects on sperm quality, including reduced sperm count, motility, and morphology.
  2. Erectile Dysfunction: Tobacco use is a known risk factor for erectile dysfunction, which can impact sexual function and fertility.
  3. DNA Damage to Sperm: Smoking can cause damage to the DNA in sperm, potentially affecting fertility and increasing the risk of genetic abnormalities in offspring.

It’s important to note that quitting smoking or tobacco use can have positive effects on fertility. The negative impact of tobacco on fertility is just one of many reasons why health professionals encourage individuals, especially those trying to conceive, to quit smoking. If you are trying to conceive and have concerns about fertility, it’s advisable to consult with a healthcare provider who can provide personalized guidance and support.
