Comparison of three sperm selection methods for ICSI-DGC, Cumulus column, and incubation with supernatant product of adipose tissue-derived adult stem cells: An experimental study.
Article in International journal of reproductive biomedicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundThe examination of sperm parameters and sperm DNA integrity are necessary for male fertility expression. These parameters can be affected by method of sperm separation.
objectiveTo measure the damage of each sperm separation method on the sperm parameters and sperm DNA integrity. MATERIALS AND
methodsIn this experimental study, semen samples of 20 infertile men with asthenoteratozoospermia (Infertility Research Center, Qom, Iran, 2017) were processed in three ways: density gradient centrifugation (DGC), cumulus column, and incubation with supernatant products of adipose tissue-derived adult stem cells (SPAS). The results of sperm parameters and DNA fragmentation before and after the process were statistically analyzed.
resultsThe number of separated sperms by normal morphologies during the SPAS and the cumulus column was significantly more than the corresponding population in the DGC group. In addition, although all three methods have the same ability to increase total sperm motility and the number of recovered sperms, in the field of forwarding movement and DNA fragmentation, the SPAS method performed more efficiently (p = 0.021).
conclusionSperm parameters and DNA fragmentation in the SPAS group were better than those in the DGC and cumulus column groups. Furthermore, it has been shown that the sperm capacity was increased with the SPAS method. However, the rearrangement of sperm chromatin by reducing the disulfide bridges and providing the possibility of re-histone over capacity causes a significant reduction in DNA fragmentation.
