Cannabis impacts female fertility as evidenced by an in vitro investigation and a case-control study.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Cannabis consumption and legalization is increasing globally, raising concerns about its impact on fertility. In humans, we previously demonstrated that tetrahydrocannabinol (THC) and its metabolites reach the ovarian follicle. An extensive body of literature describes THC's impact on sperm, however no such studies have determined its effects on the oocyte. Herein, we investigate the impact of THC on human female fertility through both a clinical and in vitro analysis. In a case-control study, we show that follicular fluid THC concentration is positively correlated with oocyte maturation and THC-positive patients exhibit significantly lower embryo euploid rates than their matched controls. In vitro, we observe a similar, but non-significant, increased oocyte maturation rate following THC exposure and altered expression of key genes implicated in extracellular matrix remodeling, inflammation, and chromosome segregation. Furthermore, THC induces oocyte chromosome segregation errors and increases abnormal spindle morphology. Finally, this study highlights potential risks associated with cannabis use for female fertility.
