Does Smoking Weed Affect Sperm?

Does Smoking Weed Affect Sperm?

Marijuana is one of the most common recreationally used drugs in the US. In fact, 24 states have legalized recreational marijuana. Statistics show that one in five Americans have tried marijuana once in their life and many use it on a regular basis. If you are one of the men that fall into this category and have questioned if your use of marijuana affects your sperm the answer is yes, it can.

Studies have shown that men who had used marijuana at least once a week for the past three months had a 30% lower sperm concentration or sperm count. Men who regularly used cannabis had a twice increased risk of poor sperm morphology (poor shaped sperm). We know that it is vital for sperm to be good swimmers for conception and the more moving sperm the higher the chance of fertility, which is key. Many studies have shown that more exposure to marijuana can cause lower percentages of motile sperm. 

How does smoking weed affect a sperm donor or potential donor? The use of marijuana could harm your sperm’s health. It can affect survival, motility, and morphology. Sperm analysis may discover that the quality of your sample is affected by your use and may determine whether you are selected to become a sperm donor.
