What was done
Narrative mini-review examining published literature on the effects of cannabis consumption on male reproductive markers, sex hormone production, sperm production, sperm function, and the endocannabinoid system.
What was found
The abstract reports no numbers or statistical metrics. Qualitatively, current evidence regarding cannabis effects on male reproductive hormone production is contradictory, but most reviewed studies associate cannabis use with decreased sperm concentrations.
Why it matters
Provides clinical context on how cannabis exposure relates to semen parameters to aid clinicians in counseling infertile couples and reproductive-aged men.
Limits
The abstract provides no quantitative data, effect sizes, or study counts. As a narrative mini-review, it lacks systematic search methodology and reflects an evidence base with conflicting findings regarding hormonal outcomes.
