Suppression of porcine polyspermy using mechanical vibrations during in vitro fertilization.

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
The efficiency of porcine in vitro fertilized (IVF) embryo production remains low. Polyspermy is considered a contributing factor to this result. In this study, we investigated the effects of mechanical vibrations during the co-culture of oocytes and spermatozoa on fertilization parameters and subsequent embryonic development. The rate of polyspermy decreased significantly in all vibration culture groups compared with the stationary culture (control) group (P < 0.05). Regarding subsequent embryonic development, the blastocyst formation rate was significantly improved in the middle-vibration culture group compared with the control group (P < 0.05). However, the high-vibration culture group had the lowest sperm penetration rate and did not show any improvement in monospermy rate and normal fertilization efficiency. In addition, their in vitro developmental status was the lowest. These results indicate that moderate mechanical vibrations during insemination effectively suppress polyspermy and improve porcine IVF embryo production efficiency.
