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

objectiveThis study aimed to assess the effects of sperm DNA fragmentation in parents belonging to different age groups. The couples included in the study comprised normozoospermic men and infertile women undergoing conventional IVF.

methodsThe results obtained from 163 conventional IVF cycles were analyzed retrospectively. The couples enrolled in the study included women aged between 30 and 37 years. Sperm DNA fragmentation was studied using the TUNEL assay. The patients were split into four groups based on male age and sperm DNA fragmentation, as follows: Group 1: ≤39 years and TUNEL assay ≤20%; Group 2: ≤39 years and TUNEL assay >20%; Group 3: ≥40 years and TUNEL assay ≤20%; and Group 4: ≥40 years and TUNEL assay >20%.

resultsNo significant differences were found in semen parameters or fertilization rates between groups. Groups with <20% sperm DNA fragmentation showed significant differences in other parameters, including higher blastocyst formation rate (Group 1: 63% and Group 3: 60% vs. Group 2: 43% and Group 4: 41%, p<0.05) and higher expanded blastocyst formation rate (Group 1: 42% and Group 3: 40% vs. Group 2: 21% and Group 4: 18%, p<0.05). Miscarriage rate was significantly higher in Group 4 (42% and 46% vs. 5%, 25% and 5% in Groups 1, 2 and 3, respectively, p<0.05).

conclusionsOur results showed lower blastocyst formation rates from IVF when males had high levels of sperm DNA fragmentation. Higher miscarriage rates were also observed in couples with males aged 40+ years. These results reinforce the need to inform couples with male partners aged 40+ years about the potential risks inherent to fertility treatment.
