Methylation Status of cAMP-responsive Element Modulator (CREM) Gene in Infertile Men and Its Association with Sperm Parameters.

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 methylation pattern of non-imprinting genes was little studied, although it is widely known that the abnormal methylation levels of imprinting genes are associated with different forms of male infertility. The purpose of this research was to assess the CREM gene's methylation status and seminal characteristics in infertile individuals who were potential intracytoplasmic sperm injection (ICSI) candidates. A total of 45 semen samples (15 normospermia, 15 asthenospermia, and 15 oligoasthenoteratospermia) were examined. Using aniline blue (AB) staining, we carried out conventional semen analysis, chromatin quality, and sperm maturity testing. DNA was taken from semen samples, and all isolated DNA was assessed using Nanodrop and gel electrophoresis. A quantitative methylation-specific polymerase chain reaction (Q-MSP) approach was used to quantify the methylation at the DMRs of the CREM gene. According to our findings, sperm count (P=0.012), concentration (P= 0.019), motility (P=0.006), progression (P=0.006), and normal morphology (P=0.004) were all inversely correlated with abnormal sperm chromatin condensation. Additionally, we noted that the methylation level of the CREM gene was considerably more significant in the oligoasthenoteratospermia group compared to the asthenospermia and normospermia groups (P<0.05). Additionally, sperm count (P=0.043), progression (P=0.026), and normal morphology (P=0.024) were all inversely linked with CREM methylation. Overall, the abnormal CREM methylation patterns have a negative impact on sperm parameters. Additionally, the CREM gene's DNA methylation status may serve as an epigenetic indicator of male infertility.
