Rescuing Fertilization Failure in ICSI: A Narrative Review of Calcium Ionophore Activation, PLCζ Testing, and Embryo Morphokinetics.
Review in Biomedicines, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Fertilisation failure following intracytoplasmic sperm injection (ICSI) is a significant challenge in assisted reproductive technology (ART), particularly in the absence of an identifiable cause. Artificial oocyte activation (AOA), typically with calcium ionophores, has emerged as a potential solution in scenarios characterised by a deficiency of phospholipase C zeta (PLCζ). This narrative review consolidates the latest clinical and experimental data regarding the application of calcium ionophores for oocyte activation, the significance of PLCζ testing in instances of unexplained fertilisation failure, and the impact of AOA on the morphokinetics and developmental potential of embryos. AOA has demonstrated an enhancement in fertilisation, cleavage, and pregnancy outcomes in specific patient populations, including individuals with diminished ovarian reserve or those who have previously attempted conception unsuccessfully. Although AOA appears to have no impact on embryo morphokinetics, certain studies indicate slight alterations in early cleavage features. The available statistics indicate that there are no significant safety concerns about outcomes for babies. This finding underscores the significance of tailored ART methodologies that incorporate molecular diagnostics and targeted AOA therapies. It emphasises the necessity for additional prospective trials to enhance patient selection and long-term safety surveillance.
