The effects of physical activity on female fertility: a narrative review.
Review in Journal of assisted reproduction and genetics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Infertility is the inability to conceive after 1 year of regular unprotected sexual intercourse. Modifiable factors such as lifestyle interventions and nonmodifiable factors (advanced maternal age or reproductive disorders) can impact female fertility. Despite the still suboptimal success rates, assisted reproductive technologies (ARTs) remain a useful tool to overcome reproductive challenges. However, additional strategies to improve fertility are still required. Physical activity (PA) impacts overall health, including reproductive function. The effects of PA depend on its frequency, intensity, and duration and may vary depending on the individual's health status and reproductive context. This makes designing a one-size-fits-all PA regimen to improve fertility a particularly challenging task. To address this issue, we review and discuss the existing evidence regarding the impact of PA on the female reproductive system. Human studies indicate that women trying to conceive, women undergoing ART, and pregnant women should engage in regular moderate PA, since it is proven to be beneficial to both women and fetus. In contrast, excessive exercise, especially combined with low caloric intake, can negatively impact ovarian function and the female reproductive axis. Animal studies, in turn, provide relevant insight into the molecular/cellular consequences of PA: on how it affects hormonal changes, follicle development and integrity, oocyte mitochondrial fitness, spindle organization/chromosome alignment, and transcriptomic modifications, otherwise difficult to study in human samples. Overall, understanding how PA alters the female reproductive system might be key to establishing new therapeutic strategies to tackle infertility.
