Does Smoking Weed and Drinking Milk Lower Sperm Count?

Marijuana (cannibis) and milk (and other dairy products) are both potentially related to sperm count because of how they interact with the human body uses and stores fat. While the effects of these two things aren't only negatively impactful on sperm count, it's important to understand how and when they can have a negative effect on sperm count and sperm motility.

How Long After Quitting Smoking Weed Does Male Fertility Improve

Since THC, the psychoactive part of marijuana, effects your body’s fat cells, it’s stored in your body for extended periods of time. This means that even after not consuming marijuana for days or weeks, it’s still possible that it’s having an effect on your system. For heavy marijuana users, or users with a higher body fat percentage, marijuana/cannabis can stay in your system for a month or slightly longer. After this month or so time period, it’s safe to assume that your body is on the path back to normal sperm production.

Marijuana use can potentially lower sperm count, among other things. From a 2021 study:

“In-depth research on the final studies concluded that marijuana seems to have specific adverse effects on the sperm parameters, namely, sperm count, concentration, motility, morphology, capacitation, and viability, thus affecting fertility in men. Certain hormone levels, including testosterone, luteinizing hormone, and follicle-stimulating hormone, also drew attention, potentially impacting men's fertility; however, a finite inference could not be substantiated by the studies. Although the studies show significant effects in sperm parameters and organic sexual dysfunction, it is also to be noted that these studies are observational only and are conducted in small groups in multicenter geographical locations where other lifestyle patterns could be confounding (1).”

Does Milk Increase or Decrease Sperm Count

Milk can have an effect on sperm count, but not in the way you might think. It’s actually dairy in general. More specifically, the fat content of dairy. Studies have shown that lower fat dairy product consumption results in a higher sperm count and increased sperm motility when compared to men consuming higher fat dairy products. From a 2014 study:

“Low-fat dairy intake was positively related to sperm concentration and progressive motility. On average, men in the highest quartile of intake (1.22–3.54 servings/day) had 33% (95% confidence interval (CI) 1, 55) higher sperm concentration and 9.3 (95%CI 1.4, 17.2) percentage units higher sperm motility than men in the lowest quartile of intake (≤0.28 servings/day). These associations were primarily explained by intake of low-fat milk. The corresponding results for low-fat milk were 30% (95%CI 1,51) higher sperm concentration and 8.7 (95%CI 3.0, 14.4) percentage units higher sperm motility. Cheese intake was associated with lower sperm concentration among every day smokers. In this group, men in the highest tertile of intake (0.82–2.43 servings/day) had 53.2% (95%CI 9.7, 75.7) lower sperm concentration than men in the lowest tertile of cheese intake (<0.43 servings/day) (2).”


Does Drinking Water Increase Sperm Count

Water is essential to your body’s ability to create both sperm and semen. Semen especially, is a mucus like substance, and is mostly water. Drinking enough water will ensure that your body can make the highest quality semen. That being said, drinking water won’t necessarily increase your sperm count on its own, but it can increase sperm motility. Sperm motility is the sperm’s ability to move efficiently, and effectively fertilize an egg. Without quality semen a sperm is less able to move effectively.
