1 · What the graph read from it

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.

2 · The registry

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

Few studies have been conducted on the paternal effects on embryogenesis as compared with studies on maternal effects. The fertility potential of sperm decreases with genomic material abnormalities. Damaged DNA of sperm has been correlated with poor fertilization, reduced implantation and pregnancy rates, and increased production of aneuploid embryos. Evidence suggests that the role of sperm in embryogenesis goes beyond genomic material transfer, and centrosomes, sperm-derived cytoplasmic factors, paternal mRNA, and small RNAs are essential for early embryonic development. Epigenetic factors like histone modification and DNA methylation participate in the regulation of gene expression in sperm. The etiology of sperm chromatin abnormalities is important in male fertility and may affect reproductive outcomes. Success in implantation depends on the quality of the fertilized sperm and oocyte as well as the type of assisted reproductive techniques. Therefore, male factors affecting development of embryo can play a role in the failure of assisted reproductive techniques. Further studies are needed to evaluate clinical aspects and the risks of transmitting genetic or epigenetic disorders to provide safe therapies for infertility.
