Does Marijuana Affect Fertility? What Research Shows

People ask the question “does marijuana affect fertility?” a lot. Whether they’re planning a family or just thinking long term about their health, they have questions about how cannabis affects reproduction.

The short answer: marijuana can influence fertility — but effects depend on use, dosage & biology of the individual. Marijuana interacts with our reproductive systems using the endocannabinoid system — a network of receptors throughout the body that regulate mood, sleep, appetite, and hormone levels. The same receptors that regulate mood, sleep, appetite, and hormone levels are found in reproductive organs and affect the way hormones are produced.

That’s why THC can potentially affect the way we produce hormones in the reproductive system in both men and women.

Male Fertility Effects of Cannabis:

• Reduced Sperm Count With Heavy Use
• Changes In Motility (Movement) Of Sperm
• Temporary Fluctuations In Testosterone Levels
• Altered Shape Of Sperm

A 2020 clinical review stated that frequent marijuana use may negatively affect the quality of semen; however, occasional marijuana use has had inconsistent results regarding negative effects on semen quality.

“The relationship seems to be dose dependent — regular and high-dose use is associated with greater changes in sperm parameters.”

Additionally, most studies conclude that the negative effects on male fertility from marijuana use appear to be reversible once an individual stops using marijuana.

Female Fertility Effects of Cannabis:

• Timing Of Ovulation May Be Affected
• Temporary Disruption of Menstrual Cycles
• Potential Negative Effects on Implantation Processes
• Hormone Fluctuations That Could Negatively Affect Fertile Windows

There is still very little research done on marijuana’s effects on female fertility and it is somewhat conflicting. There is no clear evidence of any negative effects from occasional use on female fertility.

“Current research does not support permanent reproductive harm; however, heavy and/or prolonged exposure may affect cyclic regulation.”

Other Lifestyle Factors Are Much More Important Than You Think

There are a number of factors outside of marijuana that significantly affect fertility. As such, numerous studies have consistently shown that there is a stronger association between poor fertility and:

• Stress Over Time
• Sleep Patterns
• Alcohol/Tobacco Use
• Diet And Weight
• Environment

Therefore, marijuana is just part of a much broader picture of overall health.

Numerous healthcare providers recommend limiting/reducing or quitting marijuana altogether when actively trying to conceive.

Quality and Transparency Matter

When deciding to consume marijuana, it is essential that the product you purchase is high-quality. Therefore, knowing exactly what you are consuming and at what level of cannabinoids is crucial. The best way to ensure this is to select reliable products with accurate labelling and description of the amount of cannabinoids contained within each product.
