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

backgroundThe possible effects of COVID-19 vaccines on reproductive health and male fertility in particular have been discussed intensely by the scientific community and the public since their introduction during the pandemic. On news outlets and social media platforms, many claims have been raised regarding the deleterious effects of COVID-19 vaccines on sperm quality without scientific evidence. In response to this emerging conflict, we designed this study to evaluate and assess the effect of the Pfizer-BioNTech mRNA COVID-19 vaccine on male fertility represented by the semen analysis parameters.

resultsComparing the semen parameters of the participants before and after vaccination, no statistically significant effects on semen volume, pH or normal sperm concentration and morphology were shown. However, there were statistically significant differences on total sperm motility (P = 0.05) and progressive motility (P = 0.02). These differences are clinically insignificant given the fact that both readings before and after vaccination were within the normal ranges, according to the WHO manual guidelines for the examination and processing of human semen.

conclusionOur data suggest that the Pfizer-BioNTech mRNA COVID-19 vaccine has no deleterious effects on semen parameters.
