Primordial Follicle Response to Two Methods of Ovarian Cortex Retrieval and Vitrification: A Pilot Study.
Article in Cureus, 2025. 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
Cryopreservation and transplantation of ovarian cortical tissue are novel techniques to preserve fertility in young patients undergoing gonadotoxic treatments that may affect fertility. Vitrification has demonstrated growing success in restoring ovarian function and achieving pregnancy post-grafting. It helps maintain communication between follicles and interstitial tissue, which is essential for follicular growth. This study compares two ovarian cortex dissection techniques (strips and layers) using an ovine animal model. The results indicate that manipulation of the ovarian cortex affects primordial follicle activation and stromal tissue during vitrification, potentially compromising oocyte viability and reproductive potential. Additionally, the distribution of primordial follicles in ovarian tissue varies, influencing transplantation efficiency. Both dissection methods increase follicle activation, suggesting that mechanical manipulation impacts outcomes. These findings underscore the need to optimize tissue processing to enhance fertility preservation, particularly by understanding the roles of the stromal and extracellular matrix (ECM) in maintaining follicle dormancy and viability post-vitrification and reimplantation.
