Method for long-term room temperature storage of mouse freeze-dried sperm.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Permanent preservation of genetic resources may be indispensable for the future of humanity. This requires liquid nitrogen, as is the case for preserving animal sperm. However, this technique is expensive and poses a risk of irrecoverable sample loss on non-replenishment of liquid nitrogen in case of natural disasters. In this study, we demonstrate that lyophilization may be used as a reliable method for long-term preservation of mouse sperm at room temperature. Sperm from four mouse strains were freeze-dried and stored in a non-temperature controlled room for 5-6 years. Although the ability of the stored sperm to activate oocytes had diminished slightly, healthy offspring were obtained by artificially activating the oocytes after sperm injection. Moreover, the birth rate did not decrease even after ≤ 6 years of storage. Furthermore, owing to its low cost, safety, and ease of storage at any location, we believe that this method could be a major mode of preserving mammalian genetic resources in the future.
