Comparison of semen preservation methods and in vitro fertilisation embryo quality in Simmental cattle.

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
objectiveSemen quality plays a crucial role in embryo formation in cattle. This study aims to compare the effects of 0°C refrigerated semen and liquid nitrogen-frozen semen on the quality of in vitro fertilized embryos in Simmental cattle.
methodsSemen from six bulls was devidedt equally into two groups. One was diluted with cold storage solution and stored at 0°C for 72 h; the other with cryopreservation solution and preserved in liquid nitrogen for 72 h. Post-storage, sperm quality (motility, progressive motility via computer-assisted sperm analysis, and acrosome/plasma membrane integrity) was assessed, along with malondialdehyde, reactive oxygen species, adenosine triphosphate, and mitochondrial membrane potential levels. For in vitro fertilisation (IVF), oocytes from Simmental cows (>50 per group) were inseminated with the two semen groups. At 45 h post-IVF, embryo cleavage rate was recorded; on day 8, blastocyst rate was determined. Embryos then underwent BrdU staining (proliferation) and TUNEL staining (apoptosis), with proliferation and apoptosis levels quantified via marker genes.
resultsThe results showed that compared with liquid nitrogen-frozen semen, 0°C refrigerated semen exhibited significantly higher sperm motility, forward motility rate, acrosome integrity, and plasma membrane integrity (p<0.05). in vitro fertilized embryos also exhibited significant increases in quality and quantity (cleavage rate and blastocyst rate) (p<0.05), and embryos derived from 0°C refrigerated semen contained significantly more proliferating cells (p<0.05) and fewer apoptotic cells (p<0.05) than those from frozen semen.
conclusionThese findings suggest that 0°C refrigerated semen is superior to liquid nitrogen frozen semen in terms of sperm quality parameters and in vitro embryo development.
