Tell your clinician about weed when erections, desire or orgasm change. The research doesn’t let anybody honestly promise it’ll help or guarantee it isn’t part of the problem.
If your erections, desire or orgasm changed, talk about the cannabis. You don’t have to crown it a sex drug or blame it for every time your dick said ‘fuck it.’ Some men report better sex and others report problems. Take those reports seriously without using them to claim weed treats the problem or caused the change you’re having.[3]
What to bring to the appointment
Write down what changed, the cannabis products you use and how often. Include alcohol, other drugs, medicines and whether you’re trying for a pregnancy. Separate erections, desire and orgasm instead of calling everything low testosterone. Have the clinician look for other reasons your erections, desire or orgasm changed, then work out together what to do about cannabis. Give them the actual use, not the amount you think sounds respectable.[3][5][6]
Feeling better isn’t proof it fixes erections
Before telling a guy cannabis will help his sex life, I’d want better human research than the 2023 review found. The authors found limited quality research on men’s sexual health, and their separate look at online discussions found conflicting experiences. Forums tell you what people are saying. They don’t tell you how often cannabis helps, whether it treats premature ejaculation or how much to take to get your dick cooperating again. A confident username doesn’t fix that gap.[3]
You can take someone’s experience seriously without recommending it to everybody. Sex feeling different while you’re high doesn’t establish reliable erections, improved fertility or a benefit that lasts after the drug wears off. The review didn’t prove those things. Don’t add them because you liked your experience.[3]
The erection studies don’t settle the cause
A 2019 review combined five studies comparing users and nonusers. Cannabis users had higher odds of erectile dysfunction, but the studies differed a lot. They weren’t trials assigning men to cannabis, and the authors wanted research following people over time. Bring it up, but don’t tell a guy that comparison proves weed caused his erection problem.[1]
‘Almost four times the odds’ doesn’t predict your next erection. An association doesn’t show cannabis caused it, and the review’s prediction interval included no association. The studies were about smoking too, not every edible, concentrate and pattern of use. Keep the concern and the limitations in the same conversation.[1]
The genetic study isn’t a clean bill of health
A paper published online in 2024 used genetic data to look at cannabis use and erection problems. It didn’t find evidence supporting a causal link between genetically predicted cannabis use and erectile dysfunction or the hormones it examined. That’s useful information. It still isn’t an experiment with whatever product you’re taking tonight.[2]
Genetic estimates of lifetime use or cannabis use disorder don’t directly test every product, amount or immediate effect. Not detecting a link doesn’t establish that every effect is zero. The paper didn’t prove weed harmless, and it didn’t prove the older association was entirely something else. ‘Science says I’m fine’ is doing more work there than the paper did.[2]
Testosterone and fertility are separate questions
A review of nine studies found no statistically clear difference in testosterone between users and nonusers. Its combined estimate for abnormal semen findings wasn’t statistically clear either. The authors said the limited, varied evidence couldn’t rule out an effect. That doesn’t prove permanent damage, but it doesn’t clear your fertility either. Those are different claims.[4]
The American Society for Reproductive Medicine also describes inconsistent cannabis and fertility findings. Its committee opinion advises discussing recommendations to reduce or stop marijuana before conception. If you’re trying for a pregnancy, discuss it with the clinician helping you. A normal testosterone result doesn’t tell you what your sperm are doing or your chances of a pregnancy.[5]
Take the actual problem seriously
Cannabis can impair attention, decisions and coordination. Don’t drive after using it, and know that alcohol can increase the impairment. If you can’t control the use or it keeps pushing aside things you care about, get help with that as well. You don’t get the rest of the problem handled by only mentioning the erection.[6]
Get help for ongoing sexual changes without waiting for everybody to agree on weed. Don’t assume cannabis caused all of it or dismiss the change because a paper didn’t prove cause. Don’t follow an internet dose, stopping schedule or promised reset. Bring the product and your actual use to the appointment, and work out the plan with your clinician.[3][6]
