Human sperm centrosomal function during fertilization, a novel assessment for male sterility.
Review in Human cell, 2004. 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
In human fertilization, the sperm introduces the centrosome-the microtubule organizing center-and microtubules are organized within the inseminated egg from the sperm centrosome. These microtubules form a radial array, the sperm aster, the functioning of which is essential for pronuclear movement for the union of the male and female genomes. We established functional assay for human sperm centrosomal function, by using heterologus ICSI system with bovine and rabbit eggs. After human sperm incorporation into mammalian egg, we observed that the sperm aster was organized from sperm centrosome, and the sperm aster enlarged as the sperm nuclei underwent pronuclear formation. The normal human sperm aster formation rate at 6 h post-ICSI were 60.0% in bovine egg and 36.1% in rabbit egg, respectively. However, sperm aster formation rate following heterologus ICSI into bovine eggs with teratozoospermia (globozoospermia, dysplasia of fibrous sheath) were low. These data indicate that human sperm centrosomal function is low in abnormal shaped sperm. Wherus, elucidation of human sperm centrosomal function can lead us to find a new type of failure in "post ICSI events in fertilization".
